7.3.5. Unsuccessful closing operation
operation checks the correct position of the
sensors at the end of the operations (after 95ms
magnetic actuators).
If the position is incorrect (i.e. both position
open (autotrip) is performed. If this opening is not
performed correctly the status go to NOT READY
After 10 autotrip operations the Ready LED is
turned off and the unit go in NOT READY
condition. In this case it is necessary to reset the
unit (remove the auxiliary supply and discharge
the capacitors).

Even after one successful operation the
unsuccessful operation counter is continuing to
increment the counter.

The above table is valid when the UV
function is enabled.
Note: When the UV function is disabled, the
UV input is always High.
7.3.8. Auxiliary Voltage Interruption (auxiliary
voltage for the capacitor charge)
Approximately one second after a voltage
interruption, a corresponding signal occurs over

It is then possible to open the apparatus, by
means of remote signals or by using local push
