6.3.1 Reset alarms
The Power Unit is equipped with internal protections which can block the system or some of its
functionalities. Using the RESET ALARMS menu, you can unlock the alarm and reset normal
operation. If the fault persists, the Power Unit returns to the previous lock position.
In some cases, RESET is necessary to simply restore a fault signal, which does not cause any
lock condition of the Power Unit. Lock conditions that impose manual reset are:
 A10 BATTERY FAULT
 A12 STOP TIMEOUT SHORT CIRCUIT
 A29 MAINTENANCE REQUIRED
 A33 ASYMMETRIC LOAD
 A40 MIN DC VOLTAGE
 A41 MAX DC BATTERY CURRENT
 A50 CURRENT INVERTER SATURATED
 A52 UNDER VOLTAGE LOCKOUT
 A55 PARALLEL CABLE DISCONNECTED
 Restart of the Power Unit after stoppage following local EPO
For a description of the Power Unit status in each of the lock conditions previously listed, refer
to the "Faults and alarms" section.
AS28 CRITICAL STOP
NOTE: A test must be carried out on the Power Unit before restart, contact
customer service.
The Power Unit is equipped with protections which can cause it to lock.
Before resetting the alarm, ensure there are no critical faults on the Power Unit.
To reset this alarm, the "RESET ALARMS" procedure must be carried out as
indicated above and completely restart the Power Unit.
6.3.2 Battery test
The BATTERY TEST section allows you to run a short battery discharge test. If the battery is
not sufficient, at the end of the test, the "A10 BATTERY FAULTY" alarm will be generated.
If configuration of the battery is individual, this section will be disabled, but it will be present in
the controls of the system.
Possible power loss
This test can be risky for the continuity of the changes, if the battery is not completely
charged.
