2 Overview The system consists of the components: ART.NO.
• EHS control module CM3 9341100100, 140, 150, 160, 170, 180
• Input/output module IO 8/8/4 9341100300
• Relay module RK 16/8 9341100400
• Conti Control Module CCM 9341100500
• Fieldbus interface BI 9341100200 or 9341100250
The EHS control module CM3 is for the control and monitoring of electro hydraulic swivel drives. Op-
eration can be carried out manually with the assistance of the control module operation elements, via
digital inputs and outputs of the control module and via a serial data connection to a supervisory con-
trol system. The CM3 control function can be adapted to the different actuator types by means of a
quadruple switch.
The input/output module IO8/8/4 has 8 analog inputs, 8 digital inputs and 4 digital outputs and is for
monitoring and output of control signals. Link-up to a supervisory control system is carried out via a
serial data connection.
The RK16/8 module provides 8 relay outputs (normally open) and 16 digital inputs with opto-couplers.
This module is primarily used to control centralized hydraulic actuators. Up 4 double acting or 8 single
acting actuators can be operated by a single module.
The CCM module is used to control centralized hydraulic actuators with analog position feedback.
Those actuators use flowmeters with digital outputs that can directly be connected to the CCM.
The fieldbus interface BI forms the interface between the bus protocol of the local module bus and the
fieldbus according to the Modbus RTU or Profibus DP standard. Furthermore, the fieldbus interface
acts as a monitor for all modules at the local bus and enables simple parameterisation of these mod-
ules.
2.1 Assembly
The modules BI, CM3 / CCM and IO are installed in a narrow, compact top-hat rail housing
(22.5x105x115, WxHxD). They are interconnected via a connector system in the top-hat rail and can
be removed from the system independently or re-applied without interfering with the function of the
overall system. The RK 16/8 module is installed in a flat top-hat rail housing (102x126x30) connected
to the local bus by means of a prefabricated connetcion cable.
CM3 CCM IO 8/8/4 BI RK 16/8
The local bus connects all modules to a 24V supply voltage, a serial databus and a common digital
control line used for lamp test. Up to 50 CM3 modules, 10 IO and 20 RK modules can be connected to
a fieldbus interface. In doing so the IO modules must be aligned to the left of the fieldbus interface and
the CM3 and RK modules to the right of the fieldbus interface.

3 EHS control module CM3 The EHS CM3 control module monitors and controls electro-hydraulic flap or valve actuators manu-
factured by Pleiger Maschinenbau. One control module is required for each actuator. The actuator can
be connected directly to the control module. The module is equipped with the necessary power relays
and actuator supply voltage fusing.
3.1 Operation
The EHS control module has several operating and display elements that enable manual on-site oper-
ation of the actuator.
switch „local - remote“
In position “local” the drive can be operated by means of the „close-0-
open“ switch. In position „remote” the can be operated using the digital
control inputs or the local serial bus.
button „close - 0 - open“
This button is used to operate the drive while the operating mode is „lo-
cal“. If the operation mode is “remote” pressing this button will indicate
the device and software version on the BI display.
Furthermore, operation of the local-remote switch causes temporary display of the module address on
the fieldbus interface. In addition, these control elements are also used for the parameterisation of the
local bus (see also: 7.1.2).
Three LED (red, yellow, green) signalise the operating status of the actuator and the con-
trol module.
LED red LED green meaning

3.2 Control functions
The control function that is required for the various types of actuators can be selected with the
assistance of a quadruple switch in the front of the control module housing. For this the trans-
parent module cover flap must be opened. To accept the new type the module has to be reset.
ATTENTION: It is absolutely necessary to adapt the control function to the type of actuator
as otherwise correct function of the actuator is not guaranteed and the actuator or
the control module can be damaged as the case may be.

3.2.1 Types of actuators
Double-acting
This actuator actively opens and closes with activated drive motor. In the event of a power failure it
stops in the current position.
Single-acting, spring close
This actuator actively opens with activated drive motor. The closing procedure is carried out by spring
force. The actuator closes in the event of a power failure.
Single-acting, spring open
This actuator actively closes with activated drive motor. The opening procedure is carried out by
spring force. The actuator opens in the event of a power failure.
MOV, motor valve
This actuator behaves likes a double-acting actuator and contrary to this automatically turns the drive
motor off upon reaching the end position. The control module always leaves the current supply
switched on during normal operation.
Spring close, mechanical override with handwheel
This actuator corresponds to a normal spring-close actuator, but can be opened manually with the as-
sistance of a handwheel. This operating status is permitted and the control module will not report this
as an error. In order to re-close the manually opened actuator this must initially be completely opened
electrically. This function is carried out automatically by the control module.

spring close, electro-hydraulic override with hand pump and separate hand valve
The actuator operates like a standard spring close type but can manually be opened by means of a
manual operated valve and a hand pump. This operation mode is signalised at the CM3 module but is
not indicated as a fault. The actuator may be closed again by the CM3 by powering the magnetic
valve of the EHS. This will open the manual operated valve again.
spring close, hydraulic override with hand pump and separate hand valve
The actuator operates like a standard spring close type but can manually be opened by means of a
hand pump. Using the hand pump will open actuator and automatically prevent the oil from flowing
back to the tank. This operation mode is signalised at the CM3 module but is not indicated as a fault.
The actuator may be closed again manually by pressing a button or by the CM3 by starting the pump
for a few s.
double acting, Ex-Type
The Ex-type actuator can only be operated in combination with the capacitor module (9311222810).
The function equals a standard double acting actuator. This kind of actuator is available with
open/close and analog position indicator.
3.2.2 Operation modes of the actuators
Operation mode: open / close
After the drive command has been given, e.g. by pushing the command key in the direction of ”close“,
the actuator will operate until the final position is reached or the maximum permissible operating time
is exceeded. The alarm output is activated if the operating time is exceeded and alarm status signal-
ised via the light-emitting diodes on the module.
Operation mode: open / step closing
To a large extent this operation mode corresponds to the open/close operation mode. Upon closing,
however, the actuator is repeatedly stopped briefly in order to extend the closing time. In this connec-
tion the closing time is extended by the set operating time, i.e. the closing time is approximately dou-
bled. The turn-on times of the actuator amount to at least 1 second. Depending on the operating time
the actuator is halted up to 20 times.
Operation mode: step opening / step closing
To a large extent this operation mode corresponds to the open/close operation mode. Upon closing
and opening, however, the actuator is repeatedly stopped briefly in order to extend the closing or
opening time. In this connection the closing or opening time is extended by the set operating time. The
turn-on times of the actuator amount to at least 1 second. The actuator is halted up to 20 times.
Operation mode: %
In this operation mode the actuator is only operated for as long as the command key is depressed or
the command is pending. The actuator can thus be stopped in any position. Only exception: Insofar as
either of the actuator limit switches is operated, the actuator is moved to the appropriate end position
when the key is released. This ensures that the actuator has actually moved completely to the end po-
sition if this is signalised by the end position switch. For example, this function is used for throttle
valves.
Operation mode: %Pos
This operation mode is only used in connection with the issue of a command via a superimposed con-
trol system. In this case the superimposed control system prescribes the desired position of the valve
as a percentage and the control module automatically moves the valve into the target position. Devia-
tions from the target position not exceeding 2% are ignored by the module. This operation mode is al-
ways replaced by operation mode % during mimic diagram operation or local command input.

manual -version 2013-07
3.3 Adjusting the operating time
The operating time of the actuator can be adjusted by means of a potentiometer on the front side of
the module. The transparent module cover flap must be opened for this. In general a fairly rough ad-
justment (-5% .. +25%) is sufficient whereby, if anything, the time should be assessed somewhat too
generously.
The operating time should only be determined exactly for actuators with a successive opening or clos-
ing function and in particular for actuators with the %Pos operation mode. A help function is integrated
into the control software for this purpose, allowing this to be very simple and reliable.
In case of a %Pos operation mode the runtime setting determines when the actuator is stopped while
it is approaching the nominal position. If the actuator stops too early and does not reach the nominal
position please increase the runtime a bit. On the other hand, if the actuator overshoots the nominal
position please decrease the runtime.
3.3.1 Calibration of the operating time
• Set the operating time to maximum (r.h. limit stop).
• Move the actuator from the closed position to the open position by selecting the “local”
operation mode and pushing the command key in the direction of “open”.
• Once the actuator has opened completely, push the command key again in the direction of “open“
and hold depressed. Now slowly reduce the operating time until the red LED also starts blinking. If
both LED are blinking, the time has been adjusted correctly.
3.4 Extended operation modes
The function of the CM3 module can be changed by setting several extended operation modes. This
feature is implemented from Version V2.0 upwards. Up to four extended operation modes can be set:
1. mimic inputs are active even in local operation mode (V2.3 or higher)
2. mimic close input is inverted, that means it is activated if connected to 0V (V2.5 or higher)
3. mimic open input is inverted, that means it is activated if connected to 0V (V2.7 or higher)
4. the alarm contact indicates the position of the local remote switch,
closed = remote, open = local (V2.7 or higher)
One or more extended operation modes may be set concurrently.
3.4.1 Mimic wire break detection (article numbers 9341100160 / 170 only)
As an alternative to the a.m. extended operation modes 2 and 3 a wire break detection for the mimic
command inputs is available. In this case the software version 3.1 or higher is required. In this version
the following extended operation modes are available.
1. mimic inputs are active even in local operation mode
2. mimic close input with wire break detection
3. mimic open input with wire break detection
4. the alarm contact indicates the position of the local remote switch,
closed = remote, open = local
For wire breakage detection the input must be permanently pulled up to the 24VDC supply voltage of
the PCM modules by a 10 kOhm to 20 kOhm resistor (15kOhm is recommended). This resistor must
be installed parallel to the contact of the command button or relay. If two parallel command buttons
are used a resistor of 30kOhm to 45kOhm must be installed parallel to each contact (36kOhm is rec-
ommended).

In case of a wire break the alarm, contact opens and the fault condition is indicated in the CM3 status
byte, Bit3 and Bit4 (see also: 8.1.2).
3.4.2 Extended operation mode set-up
Depending on the requested extended operation mode one or more type selector switches 1..4 must
be changed while the module is running. Now turn operation mode to “remote”.
• To set the extended operation push the command button to „close“ position until the yellow LED
starts flashing several times. The extended operation mode is set now.
• To reset the extended operation push the command button to „open“ position until the yellow LED
starts flashing several times. The extended operation mode is reset now. Please note that the
mimic close input must be connected to 24V if the extended operation mode shall be reset!
• to set the extended op modes the mimic inputs must not be activated!
ATTENTION: Do not forget to turn the type selector switches back to the original position.
3.4.3 Displaying extended operation modes
If at least one of the extended operation modes is set it will be displayed at the BI module if the „close“
button is pressed in operation mode „remote“. If no extended operation mode is selected the version
number of the CM3 is displayed as usual.

If any extended operation mode is set and the mode switch is turned to local mode the yellow lamps
starts flashing several times.
3.5 Start reports and self-test
Directly after the programme has started up, the module displays the last “reset“ cause by illuminating
one or two LED briefly. The module subsequently carries out a short self-test. In the event that the
self-test is not carried out successfully, the yellow LED will start to flash.
Once the self-test has been carried out successfully, the normal status display will start up.

3.6 Alarm output
Once the self-test has been carried out successfully, the alarm output is closed initially. As soon as an
error occurs the output is opened. The output is not closed until the error is reset, e.g. by entering a
new drive command. Errors that will raise an alarm are:
• power supply failure 24VDC or 230VAC
• invalid or inadmissible position indications
• timeout while closing or opening
see also 2.4
3.7 Lamp test
Terminal no. 3 on the local bus is used as a lamp test input. As soon as 24V are applied, the 3 LED
on the module are illuminated and in addition to this both report outputs “LED open” and “LED closed”
to the mimic diagram are activated.
3.8 Placing commands
Commands can be placed in three different ways:
• Using the open/close button while the operation mode is “local”
• Using the control inputs “CMD-close / CMD-open” while the operation mode is “remote”
• Using a command sent via the BI module
Note: As long as the command inputs are set, they will overrule the commands sent via the BI
module.

4 Input/output module IO 8/8/4 The IO module is an assembly group for registering analog and digital signals and for the output of
digital signals. All signal transmitters must be isolated, as this module does not provide internal poten-
tial separation. Generally speaking, this is the case for temperature and pressure sensors or limit
switches, floating switches and dry relay contacts. Insofar as this is not applicable, isolation amplifiers
or isolating relays must be used.
This also applies correspondingly to the digital outputs that are designed as short-circuit proof semi-
conductor relays, dispensing 24V supply voltage.
4.1 Displays
The module has a total of 20 LED at its disposal to display the input or output status.
• 8 green LED indicate the status of the individual measured values.
green LED input signal meaning
on >=3.8mA and <=20.2 mA valid measurement
blinking fast > 20.2mA above range or short circuit
blinking slowly >0.2 mA and <3.8mA below range
off <=0.2mA not used or wire broken
• 8 yellow LED indicate the status of the digital inputs.
• 4 red LED indicate the status of the digital outputs.
Furthermore, the LED are used to display any error status. In this connection the 4 lower and 4 upper
green LED flash alternately whilst the yellow LED indicate the error number from 1..8.
LED Error status Comment
1. address changed the address of the module was changed
2-7. reserved
8. module offline There is no data connection to the BI module
Alteration to the module address initially brings about the output of the “address changed“ error mes-
sage. This error message also brings about the display of the module address on the fieldbus inter-
face. The new module address is not accepted until the module has been re-started.
4.1.1 Start messages and self-test
Directly after the start of the programme the module displays the last reset cause by illuminating one
of the yellow LED briefly. The module subsequently carries out a short self-test. In the event that the
self-test is not carried out successfully, the two lowest green LED will start to flash.
Normal status display commences once the self-test has been carried out successfully (see above).
4.1.2 Lamp test
Terminal no. 3 on the local bus is used as a lamp test input. As soon as 24V are applied the 8 green
and 8 yellow LED are illuminated. The red LED are not activated during the lamp test.

4.2 Adjusting the address
The module address is adjusted with the as-
sistance of a quadruple switch. The switch is
to be found behind a transparent cover flap.
The address range of the IO modules starts at
51 and finishes at 60.
The range beginning with setting 0101 is also mapped to
the addresses 51 to 56. In this case the state of the digital
input is hold for at least 0,9s. By this means even very
short events like pressing a push button can be detected
securely (Version B.6 and higher).

5 Relay Module RK 16/8 The relay module provides 16 opto-decoupled digital inputs and 8 relay outputs.
The inputs are arranged in two groups with common 0V. A jumper allows to con-
nect both groups to the same 0V. The relay outputs are designed as normally
open contacts with one common terminal. The common terminal is fused
onboard. Standard fuse is 2AT, max. 10AT is allowed. The fuse is monitored. A
voltage drop of more than 100VAC will be indicated and signalled. The relay
contacts may switch up to 3A / 230V. A short cable with two plugs serves to
connect the RK 16/8 with each other.
5.1 Indication
The module is equipped with 24 LED for indication of the input and output state. An addi-
tional yellow LED is used for status display.
- 16 green LED indicate the state of the digital inputs
- 8 yellow LED indicate the state of the digital outputs
The status LED indicates the data traffic on the local bus, a fuse fail and also assists the user during
set-up of the module.
LED yellow meaning
on fuse fail, voltage drop on fuse > 100VAC
off no fuse fail, no data on the local bus
blinking no fuse fail, valid data on local bus but module is not addressed
flickering no fuse fail, communication on local bus is running
5.2 Operation
A push button is used to show and to set-up the module address and operation mode. This function is
only available in conjunction with a BI module with software version 2.1 or higher. To set up the ad-
dress the BI must run in set-up mode (see also: 7.1.3).
If BI is running in normal operation mode the push button is used to indicate the RK address. If the
button is pressed for more than 3s the software version of the RK is indicated instead of the address.
5.3 Jumper B1
If the jumper B1 is plugged on (default) the common 0V of both input groups are connected. In this
case only pin 9 of terminal X1 or X2 must be connected to 0V. If both input groups are connected to
independent supply voltages the jumper must be removed.
5.4 Counter function
To collect rapidly changing input values the RK provides a counter function for the input 1. Both rais-
ing and falling edges of the input signal are counted and stored in an 8 bit counter value. If the counter
reaches 255 it will be reset on the next edge of the input signal.
Each pulse must last at least 15ms. The counter value must be read frequently to detect a counter
overrun reliably. With a pulse duration of 15ms the counter must be read at least every 15ms*255 =
3825ms.

6 Conti Control Module CCM The CCM is used to control centralized hydraulic actuators with analog position indica-
tion. To measure the actuator’s position a flow meter with two 90° phase shifted binary
signals is used. The flow meter is inserted in the hydraulic pipe that is used to open the
actuator.
The CCM fully controls the actuator including the solenoid valves. Operation can be
done by means of local switches, external devices like mimic push buttons or via a
PCM-BI module. The module provides the required power relays and the fuses to safely
control the solenoid valves. The CCM uses the same address range as the PCM-CM3
modules. The casing equals the one of the CM3. From a BI’s point of view the CCM be-
haves like a CM3 for EHS with analog feedback.
The calibration of the CCM is done by teach-in. The module determines the volume of
the actuator as well as different compression volumes and the runtime of the actuator.
6.1 Operation
The CCM provides several control and monitoring devices for local operation of the ac-
tuator.
switch „local – remote“
In position “local” the actuator can be operated by means of the „close-
0-open“ button. In position remote the actuator can only be operated via
local bus or digital control inputs.
button „close – 0 – open“
In operation mode „local“ this button is used to control the actuator. In
operation mode “remote” the button is used to indicate the version of the
device respectively the software.
set button
Pressing this button in local operation mode will start the calibration
function. A transparent plastic cover protects the button against unin-
tended use.
The address setting of the CCM is done in the same way that is described for the CM3 (see also:
7.1.2).
6.1.1 Status LED
Three LED (red, yellow, green) signalise the operating mode of the actuator and the control
module.
LED red LED green Meaning

on blinking 1/s actuator in closed position, open command received
off blinking 1/s actuator is opening, left closed position
off on actuator in open position
blinking 1/s on actuator in open position, close command received

LED yellow Meaning
on missing coil supply voltage
off supply voltage OK, no valid data on local bus
blinking supply voltage OK, valid data on local bus but CCM not properly addressed
flickering supply voltage OK, local bus interface OK
6.1.2 Position measurement
A flow meter inserted in the hydraulic pipe that opens the actuator is used to determine the actual po-
sition of the drive. Several compression volumes are considered to determine the position as exactly
as possible.
As an incremental measuring is used referencing is required from time to time. Each time the final po-
sitions are reached (actuator stops) and the position is less than 3% or more than 97% the actual po-
sition is set to 0% respectively 100%.
6.1.3 Position indication
Two 7 segments LED displays are used to indicate the current position of the actuator. The final posi-
tions are indicated as for “close” respectively for “open”. All intermediate positions are indicated
in percent ...
The decimal point of the lower digit flashes whenever the position value is referenced. A synchronous
blinking of both decimal points indicates that the position value has not yet been referenced after the
CCM was turned on. In this case the shown position value could be invalid if the position changed
while the CCM was turned off!
6.2 Calibration
After installation the CCM must be calibrated. During calibration the CCM calculates all parameters
concerning the actuator and the piping and stores these parameters in an internal non-volatile
memory.
The calibration run is started by pressing the SET button while the operation mode is set to “local“.
The calibration passes the following steps:
- - close actuator and wait for a standstill
- - open actuator and wait for a standstill
- - close actuator once more and wait for a standstill
- - open actuator one third and wait for a standstill
- - close actuator to app. 10% and wait for a standstill
- - close actuator, wait for a standstill and store parameters
The current step is indicated on the 7 segment display ....
The calibration may be started every time when opening the actuator is allowed. During calibration the
operator has to make sure that the actuator reaches the final positions completely.

6.3 Extended Operation Modes
Besides the default operation mode, the CCM provides several extended modes. If the “set” button is
pressed for 3s while CCM is in “remote” mode the extended operation mode is shown. The upper digit
always shows . and the lower one a number. By means of the “open/close” switch the desired num-
ber can be selected. Each Bit in this number enables a certain mode. The default value is .
extended operation mode “local override“,
the inputs for the mimic push buttons are always enabled. This mode is required if the mimic
inputs are used for some safety functions that must be independent from the local / remote
switch.
extended operation mode “flow meter in pipe used to close the actuator”.
This mode is required if the flow meter is inserted in the pipe that is used to close the actuator.
Attention: During calibration run the actuator first starts opening and remains in open position
at the end of the test.
extended operation mode “very slow actuators”
this mode is required if very slow actuators are used. In this case the timeout periods are ex-
tended:
- close timeout and open timeout from 4 to 10 minutes
- calibration timeout from 10 to 20 minutes
extended operation mode “counter inhibit on lamp test”
In this operation mode the lamp test input has an additional function. When lamp test is set the
counter is blocked and no command can be entered, neither manually nor via serial interface.
The extended operation modes may also be combined. If for example you want to enable the “local
override” mode for “very slow actuators” you may add both numbers 1 and 4 and select mode .
6.4 Start reports and self test
During start-up the CCM indicates cause of the last “reset“ on the 7 segments display and performs a
short self test. If the self test fails the yellow LED starts blinking.
6.5 Alarm output
After self test is finished successfully the alarm contacts are closed. In case of a fault the contacts
open and are closed again if all faults have been removed. The alarm contacts are opened if:
• supply voltages 24VDC or 230VAC fail
• the runtime limit of the actuator is exceeded
• internal device fault
6.6 Lamp Test
Terminal no. 3 on the local bus is used as a lamp test input. As soon as 24V are applied, the 3 LED
and all segments of the 7-segment display of the module are illuminated. The mimic outputs are
turned on.
6.7 Placing commands
Commands can be placed in three different ways:
• Using the open/close button while the operation mode is “local”
• Using the control inputs “CMD-close / CMD-open” while the operation mode is “remote”
• Sending a command via the PCM-BI module while the operation mode is “remote”
Note: As long as the command inputs are set they will overrule the commands sent via the BI module.

6.8 Analog Position Signal
The CCM provides an analog 4..20mA output. The current signal indicates the position of the actuator.
• 4mA = closed
• 20mA = open
The current output is not isolated to local 24V supply voltage. The max. resistance in the current load
must not exceed 150 Ohms. The deviation between analog output and 7 segment display may be up
to 2%. This output is intended to be connectd to a position indication meter. It is not intended for
connecting a supervisory control system.
6.9 Behaviour in case of black out
If the 24VDC supply of the module fails the current counter value is stored in an internal non-volatile
memory. If the supply voltage is turned on again the old counter value is restored. It is not possible to
capture counter pulses while the voltage is turned off.

7 Fieldbus interface BI The fieldbus interface serves to connect the control and IO modules to a superim-
posed control system via a fieldbus. Furthermore, the module provides two control in-
puts and a collective alarm output. The module and the local bus are supplied with
24VDC.
Two 7-segment displays and two push-buttons serve to parameterise the module and
display system status.
Two fieldbus protocol variations are available:
• Modbus RTU, slave
• Profibus DP V0, slave
The choice of the fieldbus protocol is carried out via the parameterisation functions on the module.
The fieldbus lines are connected via terminal screws. Bus termination in accordance with the Profibus
standard can be activated via a miniature switch if required.
Note: The Profibus Interface is not available on BI modules with Art.No. 9341100250. Those BI only
provide Modbus RTU. If Profibus is selected anyhow an error message is indicated
7.1 Operation
Parameterisation of the module is carried out with the assistance of the “set“ and “prgm“ push-buttons.
The push-buttons are only accessible if the transparent lid on the module is opened. Display of the
chosen parameters is by means of two 7-segment displays.
7.1.1 Parameterisation of the fieldbus
Parameterisation of the fieldbus settings is only possible if the “prgm“ push-button is depressed for at
least 3s when switching on the module. After this all parameters must be entered in succession. The
“set“ key is always used to set the value and the “prgm“ key to accept the value. All parameters are
saved in a non-volatile memory.
Parameter sequence
Step Meaning Range of values Display (example)
1 Address, least significant digit x 0h … x Fh, x = any ……2 Address, most significant digit 0 xh … F xh, x = any
3 Selection baud rate / protocol 4k8 / 9k6/ 19k2 / 38k4 / 56k / 57k6 /
76k8 / Profibus DP
Modbus only
4 Selection of parity none / odd / even ......
If the Profibus is chosen during step 3, step 4 is not applicable.
Automatic baud rate setting is generally used for the Profibus protocol. When the last parameter is en-
tered the module changes to normal operation.
7.1.2 Setting the address of the EHS-CM3 / CCM modules
The address of the CM3 / CCM control modules is adjusted with the assistance of the CM3 / CCM
control elements. Those modules do not provide separate address switches. Operation mode change-
over on the CM3 / CCM module brings about the indication of the current module address on the
fieldbus interface for the duration of approx. 2 seconds.
As the address setting needs to be protected against unintentional alteration, it is necessary to
put the system in addressing mode. Addressing mode is set by pressing the “prgm” and “set”

keys on the BI simultaneously. This operation mode is shown as on the BI display. To leave this
mode just press both push buttons once more.
The CM3 / CCM module to be programmed is now switched to “remote“ operation mode. The
lowest available address on the local bus is now displayed by operating the command key in
any direction. An available address is an address to which no CM3 / CCM module will currently
respond. The two programming functions “delete“ and “accept“ are now available.
New modules are programmed in turn from left to right. Once programming has been completed the
fieldbus interface must be set to normal operation mode. For this both buttons are again pressed sim-
ultaneously.
PLEASE NOTE: The module address determines which register / data word is used by this actuator in
the data model of the fieldbus connection. If the address is not allocated as arranged, the wrong
valve will be activated. If possible, addressing should be carried out in such a way that the address
complies with the slot, i.e. that the 7th module, for example, is given address no. 7.
7.1.2.1 Deleting the module address
If the command key is pushed in the direction of “open“ and the operation mode is then switched to
local while the command key is depressed, the module address is erased. The module is then no
longer visible for the fieldbus interface.
7.1.2.2 Accepting the lowest available address
If the command key is pushed in the direction of “close“ and the operation mode is then switched to
local while the command key is depressed, the module address is set to the lowest available address.
This new address can be displayed again by changing the operation mode.
7.1.3 Setting the address and operation mode of the RK 16/8
The address of the RK16/8 control modules is adjusted with by means of the push button near the sta-
tus LED of the RK. If the button is pressed the module’s address is displayed at the BI. If the button is
pressed for more than 3s the module’s software version is displayed instead of the address.
As the address setting needs to be protected against unintentional alteration, it is necessary to
put the system in addressing mode. Addressing mode is set by pressing the “prgm” and “set”
keys on the BI simultaneously. This operation mode is shown as on the BI display. To leave
this mode just press both push buttons once more.
Now the push button of the appropriate RK must be pressed for some seconds. The status LED
first lights brightly and the turns off. The BI module now shows the lowest unused address for
an RK module in the range 61..80. As soon as the LED turns on again the button may be re-
leased. The RK is now programmed.
New modules are programmed in turn from left to right. Once programming has been completed the
fieldbus interface must be set to normal operation mode. For this both buttons are again pressed sim-
ultaneously.
PLEASE NOTE: The module address determines which register or data word in the data model of the
fieldbus connection to the BI is assigned to this RK. If the address is not allocated as arranged, the
wrong outputs are activated respectively the wrong inputs are read
Stetting the operation mode:
If the button is kept pressed after the LED turns on again for at least 2,5s the LED starts blinking. This
indicates the activation of the extended operation mode. In this case the state of each digital input is
hold for at least 0,9s. By this means even very short events can be detected securely. The version
changes from .x to .x if this operation mode is turned on (Version D.4 and higher).

7.1.3.1 Deleting the module address
To erase the module address the button must be pressed again. As soon as the LED turns off the but-
ton must be released. The module address is erased now and the module becomes invisible for the
BI.
7.1.4 Skipping addresses
If necessary an address gap may be inserted at an arbitrary position. If the BI module is in “set-up
mode” and the CM3 is set to “remote” operation, the lowest unused address is show when the close
button of the CM3 is pressed. Now the address may be increased by pressing the BI´s “Set” button or
decreased again by pressing the “Prgm” button. Only unused addresses are selected by the BI. This
set-up, that means the number of address gaps, is also used for further addressing of the CM3 mod-
ules until the BI´s “set-up mode” is left. (Remark: This function is only available for BI firmware version
V1.6 or higher).
Also addresses of the RK16/8 modules can be skipped. As soon as the lowest used address is shown
on the BI the “set” and “prgm” button can be used to modify the RK address.
7.1.5 Display functions
Various system data can be displayed for diagnosis purposes in connection with the “Set” and “Prgm”
keys of the fieldbus interface or the operation mode switches of the CM.
Display of the address of a CM3 module
Upon changing the operation mode (local – remote) of a CM3 its address is displayed for 2 sec-
onds via the 7 digit display of the BI (. = address 12).
Display of the lowest available address
The lowest available local address is displayed by pressing the set key of the fieldbus interface
(. = address 17). The address of the module in position 17 should be programmed as the
next CM3 module.
Display of modules that have failed
If a module does not respond to queries from the fieldbus interface for a certain period of time,
it moves to “offline“ status. The address of this module is then displayed for 3 seconds (.. =
address 13). The display of the address of the module that have last moved to offline status can
be repeated at any time by pressing the “prgm” key. Displaying .. indicates that none of the modules
have gone offline.
PLEASE NOTE: Only the change to offline status is registered. If a module never answers after
power up, it will not be displayed.
Display of control inputs 1 and 2
If control input 1 or 2 is set, or output will appear on the display.
Position indication of actuators with analog position feedback
If an actuator with analog position feedback is operated in „local“ mode the current position is dis-
played at the 7-segments display of the BI module. This indication is turned off a few seconds after
the actuator comes to a standstill. (Remark: This function is only available for BI firmware version V1.6
or higher).
Normal operation
If status display is not necessary, the display will switch to . (program execution).

7.1.6 Start messages and self test
Directly after the programme has started up, the module displays the last “reset“ cause in the form of
two digits. The module subsequently carries out a short self test. In the event that the self test is not
carried out successfully, the red LED will start to flash. If Profibus DP is selected as fieldbus the red
LED always indicates an error while the error code is shown in the display.
Once the self test has been carried out successfully the version number of the software (x.y) is dis-
played briefly. The normal status display begins subsequently (see above).
7.1.7 Power management
The BI module provides a power management function to limit the 230VAC supply current. To avoid
that the high starting current of the drives blows the fuses the actuators are started successively al-
ways one drive every 100ms. Additionally the number of running drives that are connected to the
same fuse is limited (default 8). The current that is required to keep the magnetic valve of a single act-
ing drive closed is neglected. A motor valve is treated like an EHS even though the current is much
less.
If more than 8 actuators of a group connected to the same fuse get a command, the execution of this
command is delayed in such a way that not more than 8 actuators are running simultaneously. Up to 4
of such groups can be configured for each BI. The first group begins with the drive using the address
1 and ends with address A1, the second groups begins with A1+1 and ends with A2 and so on.
The default set up uses 2 groups:
• group 1: drive 1..25
• group 2: drive 26..50
• number of drives: 8
7.1.7.1 Configuring the power management
To configure the power management the „Set“ button must be pressed for at least 3s while the BI
starts up. The display will now show . By pressing the “Set” button the group number can be in-
creased. Pressing the “Prgm” button will select this group and the last address of this group is shown
in the display. The “Set” button may now be used to increment the last address. The highest value is
50, the lowest value is the last address of the preceding group plus one. Pressing the “Prgm” button
once more will store the address and return to the group number display. If the last group (no 3) is
programmed or any group is programmed to address 50 the set-up is finished.
From BI V2.2 the number of drives running at the same time can also be adjusted. Instead of leaving
the set-up mode the number of drives is displayed in the lower digit while the upper digit shows a “.”.
The number can be changed using the “Set” button. Pressing the “Prgm” button will store the selected
number and leave the set-up mode.
PLEASE NOTE: The BI firmware secures that the last address of a succeeding group is always
higher than the last address of the preceding one. If this condition is not fulfilled the
firmware will adjust the addresses automatically.

7.1.8 Set-up of Quick Close Functions
The control input E2 of the BI module is used to activate differ-ent quick close functions. As soon as the input is set a close or open command is sent to all CM3 modules that are appropri-ately parameterised. This parameterisation is done in the set-up mode of the BI module. At first the appropriate CM3 is se-lected by changing its operation mode. Afterwards the “Prgm” push-button is pressed. The present mode is now displayed.
By pressing the „Set“ push-button the required mode is se-
lected and confirmed by pressing the “Prgm” push-button once more. The mode that is valid at pre-
sent is displayed with the decimal points turned on otherwise the decimal points are turned off.
This function must be repeated for all required CM3. Press both push-buttons simultaneously to leave
the set-up mode.
7.1.9 Alarm output
To begin with the alarm output is closed after the self test has been carried out successfully. Cyclical
testing is carried out subsequently as to whether the modules connected to the local bus are working
accurately. If a module is not available (offline) or if a CM3 / CCM module reports a fault (e.g. timeout)
or is set to local operation mode, the alarm output will be opened and not closed until the fault has
been removed and the alarm acknowledged on the CM3 module.
7.1.10 Lamp test
Terminal no. 3 on the local bus is used as a lamp test input. As soon as 24V are applied, the 3 LED
and all segments of the 7-segment display of the module are illuminated.
7.1.11 Bus Termination
If the BI module is placed at a physical end of the bus the bus cable has to be termi-
nated. This can be done by means of a miniature switch at the front of the module. If
both sliders are set to ON position the termination is turned on, if they are set to the op-
posite position the termination is turned off. All other settings are not allowed.
The bus termination is an active one and meets the Profibus standard.

8 BI Modbus interface (slave) The Modbus interface of the fieldbus interface serves to exchange data with a superimposed control
and visualisation system, hereinafter referred to as Modbus master. A register in both report direction
and control direction is used for every valve. Transmission is carried out via an RS485 connection.
The baud rate (4800-76800 baud), the parity (none, even, odd) and the Modbus address (1h..6Fh) can
be parameterised. The number off data bit is fixed to 8. One stop bit is used.
The fieldbus interface has a Modbus RTU interface (slave) and serves the following functions:
• 03 Read holding registers
• 06 Preset single register
• 16 Set multiple registers
This chapter describes the applied data model, i.e. the use and meaning of the individual registers of
the Modbus. This information is required for the preparation of the data model of the superimposed
control system and for the commissioning of the Modbus interface as the case may be. More detailed
information about the Modbus protocol may be obtained from www.modbus.org.
8.1 Modbus data model
The data model described here complies with the program version 1.5 or higher.
The first register is always used to monitor the fieldbus interface itself. The following registers are
used for the CM3 and the IO modules.
In detail, the binary digits of the registers have the following meaning:
8.1.1 Fieldbus interface BI status, register 1, (read only)
Bit Meaning
Bit0 CM3 fault, collective message
Bit1 IO fault, collective message
Bit2 reserved
Bit3 control input E1 set
Bit4 control input E2 set
Bit5 control input „lamp test“ set
Bit6 running in passive mode (see also: 10 !used only if secondary BI is connected)
Bit7 RK16/8 fault, collective message
Bit8..14 not used
Bit15 live bit, changes state every 2s *
*implemented in BI version V1.6 or higher
CM3 fault collective message
This binary digit is set if at least one EHS-CM3 reports a fault.
IO fault collective message
This binary digit is set if at least one IO module reports a fault.
Fault on the local data bus
This binary digit is set if at least one module on the local bus replies to broadcast address 0 or if fur-
ther faults arise that cannot be allocated to a specific bus participant.
Control input E1 / E2 set
This binary digit is set if control input E1 / E2 has been set (24V).
Control input lamp test set
This binary digit is set if lamp test input has been set.

8.1.2 CM3 status register (read only)
The CM3 status register includes the valve position and the valve error messages. The register num-
ber depends on the module address (1-50).
Register number = module address + 1
(50 registers, from no 2 to no 51)
The lower-order byte of the register contains the position information:
Value Meaning
0..100 actual position of valves with analog position feedback
(128..228) most significant bit is set while drive is running (add128)
101 drive closed and in a standstill
102 drive neither open nor closed
103 drive open and in a standstill
105 drive in open position, close command received
106 drive in closed position, open command received
107 drive neither open nor closed while closing
108 drive neither open nor closed while opening
109 drive indicating closed position but is still running
110 drive indicating open position but is still running
111 unknown position
The higher-order byte of the register indicates the error messages:
Bit Meaning
Bit 0: error no 0 = no error
Bit 1: (Bit 0-2) 1 = timeout while opening
Bit 2: 2 = timeout while closing
3 = invalid feedback
4 = invalid command
5 = reserved
6..7 = not used
Bit 3: command close received via mimic input*
Bit 4: command open received via mimic input*
Bit 5: local / remote switch in local position
Bit 6: no AC supply (230VAC)
Bit 7: offline, no response on local bus
The error flags 1..3 stay set until the cause of the error is removed or a new command is sent.
Runtime errors generally require resending a command.
*These status bit are implemented in CM3 firmware V1.9 or higher. The bit is set as soon as the corre-
sponding input is set and reset when the input is released. In any case the bit is set for at least 5s. If
the close input is activated the open input is assumed as deactivated regardless of the physical input
voltage.
In case of an activated wire break detection for the mimic close and mimic open inputs the wire break
case is indicated by setting both bits 3 and 4 concurrently.

8.1.2.1 Combining error messages
The above mentioned error indications are very detailed. It is not necessary or even recommended to
display all error indications on a SCADA system. A useful combination of different error messages in
several groups is recommended.
Example:
Group 1: runtime error = (error no equals 1) OR (error no equals 2)
Group 2: device error = (error no equals 3) OR (error no equals 4) OR (Bit6 is set)
Group 3: offline error = (Bit7 is set)
Group 2 and 3 may also be combined. Further fault analysis can be done by means of the LED of the
CM3 module.
Furthermore it is recommended that the SCADA control elements of an actuator are hidden or greyed
if the Bit5 is set.
8.1.3 CCM status register (read only)
The CCM status register includes the valve position and the valve error messages. The register num-
ber depends on the module address (1-50).
Register number = module address + 1
(50 registers, from no 2 to no 51)
The lower-order byte of the register indicates the position information:
Value Meaning
0..100 actual position of actuator / valve, 0 = closed, 100 = open
128..228 actual position while valve is moving
While actuator is moving and also during calibration the most significant Bit in the position byte is set.
The higher-order byte of the register indicates the error messages:
Bit Meaning
Bit 0: error message 0 = no error
Bit 1: (Bit 0-2 binary) 1 = timeout while opening
Bit 2: 2 = timeout while closing
3 = reference run required
4 = invalid position counter value
5 = self test error
6..7 = not used
Bit 3: command close received via mimic input*
Bit 4: command open received via mimic input*
Bit 5: local / remote switch in local position
Bit 6: no supply for solenoid valves (both 24VDC or 230VAC)
Bit 7: offline, no response on local bus
The error flags 1..4 stay set until the cause of the error is removed respectively a new command is
sent. Runtime errors generally require resending a command. Flag 3 is set on power up and is deleted
when the counter is referenced the first time.
The bits 3 and 4 are set as long as the corresponding inputs are set. In any case the bit is set for at
least 5s.

8.1.4 IO status register (read only)
The IO status registers contain the status of the analog and digital inputs of an IO module. An IO mod-
ule occupies a total of 9 registers. The register number depends on the module address.
The module addresses are in the range of 51 – 60.
Register number of the first register = 9*(module addresses -51) + 52
(90 registers, from no 52 to no 141)
The first register contains the status of the 8 digital inputs in the lower-order byte and error messages
in the higher-order byte.
Bit Meaning
Bit 0..7: digital input 1..8 set
Bit 8: address was changed after last start up
Bit 9: error analog input 1..8
Bit 10: used internally
Bit 15: offline, no response on local bus
The following 8 registers contain one each of the 8 measured values as 12 binary digit value (0..20mA
= 0..4000 Incr.). A valid value must be even.
Attention: An odd value indicates that the last measurement has not been updated because of an
invalid measurement.
8.1.5 Fieldbus interface BI remote control, register 142 (read/write)
This register can be used by the Modbus master to control various functions of the fieldbus interface.
Bit Meaning
Bit0 reserved
Bit1 force BI to passive mode (see also: 10)
Bit2..14 not used
Bit15 *Profibus data are valid (see also: 0)
*implemented in BI version V1.6 or higher
8.1.6 CM3 control register (read/write)
A CM3 control register is used to send a command to a valve. The register number depends on the
module address (1-50).
Register number = module address + 142
(50 registers, from no 143 to no 192)
Only the lower-order byte of the valve control register is used.
Command Meaning
0..100 position set point for %Pos drives
101 close drive
102 stop drive
103 open drive
104 acknowledge error, erase last command
111 commands by mimic diagram inputs only
If command 111 is sent the BI completely passes control to the CM3 modules. The CM3 acts as if
there is no BI. Only old CM3 versions V1.6 or lower require this command to enable the mimic inputs
permanently. V1.7 and newer always react properly on mimic inputs in remote mode and do not re-
quire this command any longer.

Any command change will reset the errors 1..4. To force a command change the following way is sug-
gested:
Set the most significant bit of the command byte to indicate a new command. The CM3 / CCM
will react on this command immediately. The bit should be kept high for at least 1s and should
be reset afterwards.
Beside resetting error conditions restarting a command may be useful in certain applications like actu-
ators that may be operated manually by hand wheel (override). If such a drive is closed by command
and opened manually afterwards a repeated close command will close it again.
example:
• send close command 128+101=229, actuator starts running, wait 1s, send close command
101
• actuator is closed
► actuator is opened manually
• send close command 128+101=229 once more , actuator starts running, wait 1s, send close
command 101
• actuator is closed again
8.1.7 CCM control register (read/write)
The CCM control register is used to send a command to the actuator. The register number depends
on the module address (1-50).
Register number = module address + 142
(50 registers, from no 143 to no 192)
Only the lower-order byte of the valve control register is used.
Command Meaning
0..100 position set point
101 close drive completely (same as 0)
102 stop drive
103 open drive completely (same as 100)
104 acknowledge error, erase last command
105 start calibration
111 commands by mimic diagram inputs only
Commands 104 and 111 are used for compatibility to older CM3 versions only.
Attention: During calibration the actuator will be completely opened and closed again. The operator
has to make sure that the actuator completely reaches both final positions.
8.1.8 IO control register (read/write)
The IO control register is used to set the 4 digital outputs of the IO 8/8/4 module. The register number
depends on the module address. The module addresses are in the range of 51 – 60.
Register number = (module address – 51) + 193
(10 registers, from no 193 to no 202)
Bit Meaning
Bit 0..3: digital output 1..4 set, outputs are reset if IO 8/8/4 goes offline
Bit 4..7: digital output 1..4 set, outputs stay on if IO 8/8/4 goes offline

8.1.9 RK status register (read only)
The RK status registers contain the status of the digital inputs and error flags of an RK module. An RK
module occupies a total of 2 registers. The register number depends on the module address.
The module addresses are in the range of 61 – 80.
Register number = 2*(module address – 61) + 203
(40 registers, from no 203 to no 241)
The first register shows the error flags in the lower byte and a 8 bit counter value in the upper byte.
Value Meaning
Bit 0: fuse is damaged
Bit 1: address button pressed
Bit 2: used internally
Bit 7: offline, no response at the local bus
Bit 8-15 8 Bit counter, all changes of input 1 are counted.
The second register shows the status of the 16 digital inputs.
Value Meaning
Bit 0: digital input 1 (24V = Bit set)
…
Bit 15: digital input 16 (24V = Bit set)
8.1.10 RK control register (read / write)
The RK control register are used to control the relay outputs. Each module uses one register.
The register number depends on the module address.
The module addresses are in the range of 61 – 80.
Register number = (module address – 61) + 243
(20 registers, from no 243 to no 262)
Value Meaning
Bit 0..7: set relay output 1..8;
all outputs are reset if the data connection between PLC and PCM system fails
Bit 8..15: set relay output 1..8;
all outputs keep the current state if the data connection between PLC and PCM system
fails
8.2 Fieldbus Watchdog
The BI Module permanently supervises the proper function of the Modbus (Profibus). The BI must re-
ceive at least one valid Modbus request every 5s otherwise the following functions will be carried out:
• A command 111 „enable mimic diagram inputs“ is sent to all CM3 modules.
• All control bits 0..3 of all IO8/8/4 are set to 0, that means that all outputs are reset
• All control bits 0..7 of all RK16/8 are set to 0, that means that all outputs are reset
We recommend to start a request at least every second. This function is implemented for the Profibus
protocol is the same way.

9 BI Profibus DP interface (slave) The Profibus DPV0 interface is available as an alternative to the Modbus and can be chosen via the
set-up menu of the fieldbus interface (BI). Automatic baud rate identification is used. Baud rates be-
tween 9600 baud and 1.5 Mbaud are permissible. If required a bus terminator (in accordance with the
Profibus standard) can be connected via a miniature two-pole switch in the front of the housing.
The advanced V1 and V2 services are not available. Differing from the Profibus standard an inexpen-
sive screw-type terminal is used for the electrical connection instead of a sub-D connector. More de-
tailed information about the Profibus protocol may be obtained from the standard EN 50170 or from
the „Profibus Nutzer Organisation“ (PNO, www.profibus.com).
Note: The Profibus Interface is not available on BI modules with Art.No. 9341100250. Those BI only
provide Modbus RTU. If Profibus is selected anyhow an error message is indicated
9.1 Profibus data model
For compatibility reasons the same data model is used as for the Modbus. 16 binary digit-wide data
words are used instead of the Modbus registers. On account of the maximum telegram length of 244
bytes a maximum of 7 IO modules can be used for the Profibus protocol. The data model is described
in the “PE_PCMV2.gsd“ GSD file (or newer versions). The meaning of the individual data words corre-
sponds to those in the registers for the Modbus protocol.
To avoid unnecessary data transfer the BI module is set-up as a modular station. The following mod-
ules are available.
Module 1 BI, status & control, 1 word read, 1 word write
Module 2 5x CM3/CCM, status & control, 5 words read, 5 words write
Module 3 10x CM3/CCM, status & control, 10 words read, 10 words write
Module 4 1x IO8/8/4, status & control, 9 words read, 1 word write
Module 5 1x RK16/8, status & control, 2 words read, 1 word write
Module 6 5x RK16/8, status & control, 10 words read, 5 words write
The module type 1 must always be inserted in first place. Next up to 50 CM3, 7 IO8/8/4 and 20
RK16/8 may be added. Please keep in mind that the number of data bytes both read and write must
not exceed 244.

9.1.3 Data Valid Bit
Some Profibus DP masters keep on sending data even if the supervisory controller is stopped. In this
case all commands are set to 0. This is not suitable for PCM system. Therefore the highest Bit15 of
the control word of the BI is used as a „Data Valid Bit“. If this bit is not set the Profibus connection is
treated as invalid.
This Bit is used only if the Bit0 of the first Parameter Byte is set to 1, otherwise the data is always
treated as valid data. This function is only implemented in BI firmware version V1.6 or higher.

10 Secondary BI Module To achieve an improved availability of the field
bus connection (either Profibus DP or Modbus
RTU) an additional, secondary BI module may
be used. This secondary module is usually
running in passive mode permanently reading
the traffic on the local bus. Therefore it will al-
ways show the latest data of all modules con-
nected but it can not and must not send any
command to the modules.
Whether a BI runs in passive or active mode
depends on its priority on the local bus. Al-
ways the BI with the highest priority becomes
active. The priority depends on the following
conditions:
Priority Condition
3 primary module, field bus connection to supervisory control is working properly
3 primary module, running in set-up mode
2 secondary module, always
1 primary module, no field bus connection and no set-up mode
If the field bus connection of the primary module fails the priority of this module is reduced to 1 and
therefore the primary module becomes passive whereas the secondary module becomes active. Be-
cause a BI running in set-up mode needs full access to the local bus the priority of the primary BI is
set to 3 if set-up mode is turned on. To use the secondary BI in set-up mode the fieldbus connection
of the primary BI must be interrupted during set-up.
The secondary BI should preferably be mounted on the right side of the CM3 modules. The control
inputs E1 and E2 are connected in parallel to the primary BI if used at all.
10.1 Parameterisation of the secondary BI module
The address setting is the only difference between primary and secondary BI. If both BI are connected
to separate field busses they both may (and preferably should) use the same real fieldbus address.
The secondary BI module is set to a fieldbus address “real address + 80h”. That means that the sec-
ondary BI with the fieldbus address 1 is set to address 1+80h = 81h.
ATTENTION: All functions described here are available only in software version 2.0 or higher!
10.2 Fieldbus interface BI status, register 1 (read only)
One entry is added to this register. As long as the BI is running in passive mode all data are valid but
no command will be sent to the modules.

10.3 Fieldbus interface BI remote control, register 142 (read/write)
One entry is added to this register. For test purpose the BI can be forced into passive mode. The
other BI will than change to active mode.
Bit Meaning
Bit1 force BI to passive mode
10.4 Operating redundant BI
Both master interfaces should be (but don’t have to be) identical. If two separate bus cables are used
even the slave addresses may and should be the same. The master software should treat both BIs ás
well as the connected modules identically. There is no need to send commands to the passive BI as
this BI can’t send commands to the connected modules. Anyhow you may do so if it is more conven-
ient. The passive flag in the BI status register should be indicated to the user. Of course both masters
must poll the primary and the secondary BIs permanently. Otherwise a failure of the secondary bus
may not be noticed.
For test purpose the master should be able to stop polling the primary bus. In this case the secondary
BI must indicate that it turned to active state a few seconds later. If turning off the primary master is
not possible the primary BI can be forced to passive mode by setting the corresponding bit in the con-
trol register.
10.5 Alarm output
The alarm output of the passive BI is always closed that means an alarm is never signalised. The ac-
tive BI behaves like a standard BI.

12 Assembly of the system Certain boundary conditions must be adhered to during the assembly of the complete control systems
in order to ensure reliable and trouble free operation.
• Only a maximum of 50 CM3 / CCM, 10 IO8/8/4 (7 for Profibus DP) and 20 RK modules are to be
connected to a fieldbus interface.
• The IO modules must be aligned to the left and all other modules must be aligned to the right of
the fieldbus interface. RK modules must be mounted on the very right side of all other modules.
• All 230VAC supplies must be fused with max. 16A B characteristic.
• The 24VDC supply may be connected several times to separate the supply for different systems
(etc. bilge, ballast). Each 24V supply is separately fused up to 4AT. All 0V supplies must be
connected directly to the same terminal. 0V supply is fused with a common 6AT fuse. For
the connection of the DC supply the BI (9, 10) or the plugs of the prefabricated cable sets must be
used.
• The local data bus and the lamp test control may be extended by means of prefabricated cable
sets. Up to 4 adapting cables and one extension cable may be used per BI module. The screen of
these cables must be connected to a PE terminal right beside the plug connector. The PE terminal
is also used to fix the modules on the rail mount.
• All control signals from and to the CM3 / CCM and IO 8/8/4 modules are supplied via the 24VDC
of the CM3 respectively the IO 8/8/4 modules.
• All cables leaving the control cabinet and being connected to the modules must be screened. The
screen must be connected extensively to the mounting plate. So-called “pigtails“, i.e. cables be-
tween the screen and a PE terminal, are not permissible.
12.1 Controlling via mimic diagram
The CM3 modules can be used without a fieldbus interface for applications in which the actuators are
controlled exclusively by a mimic diagram. The feeding-in of the 24VDC supply voltage is then via the
local bus connector pins 4 and 5. The voltage must have external fuse protection amounting to a max-
imum of 6A. Insofar as necessary, a 24VDC lamp test signal is also connected via the local bus con-
nector. The current consumption of this control input amounts to approx. 1mA per module.

12.2 Commissioning hints
Incorrectly connected drives or defective cables may cause damage of the CM3 modules or
the OC3 feedback modules. To avoid this some tests must be performed before 24VDC or
230VAC supply is turned on.
1. 24VDC and 230VAC are completely separated from each other and from protective earth (PE),
e.g. the rail-hat. Therefore a high insulation resistance must be measured between those circuits.
The insulation resistance measurement should be
performed with an insulation resistance meter with 50
to 500VDC test voltage. The following minimum re-
sistance values must be achieved:
Using a standard multi-meter as a substitute may re-
sult in uncertain results. This measuring must be per-
formed during commissioning and should be re-
peated after any repair works on the cabling of the
actuators.
2. Please also check that pin 13 of the CM3 module, this is the position feedback input 4..20mA, is
connected only for those actuators that really use an analog position feedback signal.
3. Turn on 230VAC for a few devices only and check proper operation carefully before connecting
the next devices to 230VAC.
12.3 Safety Advice
The plate beside shows an important safety advice and
must be fixed at the top-hat rail right beside the installed
CM3 modules.
If CM3 modules are mounted on different top-hat rails
one plate has to be fixed at each rail.
Pay attention to this safety advice during any kind of work on the pluggable screw terminals!
12.4 Accessories
For the proper installation of PCM systems the following accessories are required.
12.4.1 Adapting Cable
This cable is used if the 24VDC supply shall be feed several times. The length of the cable is app.
20cm must not be extended or replaced by a different cable. The modules are fixed on both sides of
the cable by means of an end holder that is fastened on the hat-rail. The right plug (4+5) must be con-
nected to 24VDC power
supply. Connect pin 4 to
the common 0V directly,
connect pin 5 to 24V fused
up to 4A.

12.4.2 Extension Cable
This cable is used to connect additional modules on a second hat-rail to the same BI module. Only
one cable can be used per BI module. The shield of the extension cable must be connected to the
hat-rail via PE terminals. These termi-
nals are also used to fix the modules
mechanically. The cable is app. 150 cm
long and must not be extended! If such
a cable is used the 24VDC power sup-
ply must be connected to the modules
separately.
