VM1Features of the control module ED2.0 (standard version)� The closing coil can only be activated when VM1 is open� The opening coil can only be activated when VM1 is closed� Closing is disabled when an opening command is active at the same time� De-activation of the opening or closing coil takes place when the relative limit position

has been reached� WRONG POSITION (auto trip) function: if the final CLOSED (or OPEN) position is

not reached within 70 ms during a closing (or opening) operation, an opening operation is immediately started to guarantee reaching a defined safe position in any case.

� Anti-pumping function ensures that only one closing-opening cycle is carried out when a closing command followed by an opening command is active; active closing command must be cancelled and reset for the next closing operation.

� Activation of the input for the closing command can be locked by means of an external locking signal.

� Input for the “lock on closing” command must be energised to be able to close the circuit-breaker (without power it inhibits closing).

VM1Features of the control module ED2.0 full version� Undervoltage function

� controls VM1 opening if the voltage applied drops below the limit of tolerance (established by the Standards)

� rated voltage value to be monitored is set in the factory in conformity with the order specifications but it can be changed by dip-switches

� to prevent UVR intervention, when the voltage drops below the specified level (e.g. in the case of motor starting), it is possible to set a trip time

� UVR function can be disabled� Monitoring function of the actuator closing and opening coil; if a fault is

detected, the luminous “READY” signal on front of the circuit-breaker turns off and the “READY/NOT READY” signalling contacts are activated.

� Additional safety opening command function; the second input of the control module for the opening function is designed so that an opening command is carried out directly even in the case of a fault in the microprocessor.

VM1

Features of the capacitor� The energy stored is suitable for an O-C-O operating cycle without recharging� The energy stored is constantly monitored by measuring the voltage of the capacitor� “READY” indication signals:

� application of the power supply voltage� “ready” status of VM1 for the next operation

� “READY” signal switched on means� (VM1 in the open position) energy sufficient for one C-O operating cycle� (VM1 in the closed position) energy sufficient for one opening operation; energy available

is sufficient for one opening operation within 60 s from interruption of the auxiliary power supply (up to 120 s with 2 capacitors)
