ACCESSORIES 7/41

Operating principles:
• a selector on the front of the MOE, is used to select the operating mode:
- AUTO: when the selector is in this position, the push-buttons on the front of the motor are locked
and covered by a sliding cover. It is possible to seal the sliding cover to avoid mode changing.
Circuit-breaker closing is commanded remotely only by means of an electric impulse, whereas open-
ing is allowed both remotely and from the front of the motor using a tool;
- MANUAL: the circuit-breaker can only be opened/closed from the front of the motor using the rele-
vant push-buttons. It is possible to seal the sliding cover to avoid mode changing;
- LOCKED: the device can be used only if the motor is in the open position and the springs are
charged. The padlock device can be withdrawn and the can be motor locked in the open position;
• operation of the motor operator via remote control is also guaranteed by permanent electrical opening/
closing impulses. Once an opening command has been given, the next closing command (permanent) is
taken over by the motor operator once the opening has been completed. In the same way, an opening com-
mand is taken over once the previous closing operation has been completed;
When the Ekip Com module is used, the MOE-E motor operator must be used instead of the MOE motor op-
erator. The MOE-E allows digital signals from the supervision and monitoring system to be used by means of
the release and Ekip Com contacts and to be converted into power signals to command the motor operator.
All the features described above for the MOE motor operator are also available on the MOE-E version.

With the XT5 MOE and MOE-E and the XT6 MOE, it is possible to define some reset logic in order to charge
the springs automatically once the circuit-breaker has tripped depending on the reset wiring
diagram chosen. Three different options are available:
• Auto Reset: the circuit-breaker is automatically reset after a trip (not due to the trip unit) and the springs
are charged;
• Remote Reset: it is possible to connect a push-button in order to charge the springs after a trip (not
due to the trip unit);
• Manual Reset: charging springs must be done manually after a trip.
As explained in the motor circuit diagram, the auxiliary contact S51 must be properly connected to enable
remote or automatic resetting. After a trip due to an overload or a short-circuit (trip unit), only a manual re-
set is permitted.
