The geared motor automatically recharges the spring after each closing
operation until the yellow indicator (7) appears.
If the power is cut off during charging, the geared motor stops and
automatically starts recharging the springs again when the power
returns.
In any case, it is always possible to complete the charging operation
manually.

having taken place is indicated by the signalling device (6 - fig. 6b).

When there is a shunt opening release, the operation can also be
