VM1Accessories available (on request)

Signalling auxiliary contacts circuit-breaker open/closed Fixed circuit-breaker (-BB1; -BB2; -BB3; -BB8):

Set of 5 make contacts plus 5 break contacts Set of 10 make contacts plus 10 break contacts

(alternatively) Withdrawable circuit-breaker (-BB1; -BB2)

Set of 5 break contacts plus 5 make contacts Transmitted contacts of the withdrawable circuit-breaker installed in the

truck (-BT1; -BT2)These contacts are either in addition or as an alternative to the position contacts (for signalling circuit-breaker racked out) located in the unit; they also carry out the function of the position contact (-BT3)

Position contact of the withdrawable circuit-breaker (-BT3)With binary input SL1 prevents remote CB closing during translation of the truck; it is supplied when the transmitted contacts -BT1; -BT2 are not required

Motorised truck (-MT) (only for VM1 for UniGear panel)

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.

VM1Features 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)
