Changes to the operating parameters and starting operations on the UPS may be potentially
dangerous for the device and for persons.
13.3.1 Resetting the device
The UPS is equipped with internal protections which block the system or some of its sections. The alarm
can be cleared and normal operation can be resumed via the
DEVICE RESET
page. In case the failure
persists, the UPS will return to the previous failure condition.
In some cases the RESET is necessary to simply reset a failure signal, then the UPS will resume
operation. The failure conditions which impose a manual reset are:
Activation of the battery fault alarm (alarm A10)
Static switch re-transfer block (alarm A17)
Scheduled maintenance request (alarm A29)
Booster shutdown due to the operation of the load symmetry sensor (alarm A33)
Inverter shutdown due to voltage control loop error (alarm A39)
Booster shutdown due to voltage control loop error (alarm A41)
Booster shutdown due to current control loop error (alarm A43)
Block due to the disconnection of one parallel cable (alarm A50)
Block due to the disconnection of two parallel cables (alarm A55)
System restart after a shutdown due to EPO activation
Several specific blocking conditions of the power modules can only be cleared by directly entering the
Settings
section of the modules (see relevant paragraph).
For a description of the UPS status in each of the failure conditions listed above, please refer to the
“Faults and alarms” section.
