8. TROUBLESHOOTING
8.2. UPS ALARMS
A01: BATTERY ALARM
Failure or problem on the battery circuit. Check the battery switch is closed.
A18: BLOCKING INVERTER FOR OVERLOAD
Reduce the load rate applied to the UPS and reset the alarms.
A20: WRONG CONFIGURATION
Error in the confi guration parameters. Please contact the support service.
A30: UPS STOPPED FOR OVERLOAD
Reduce the load rate applied to the UPS and reset the alarms.
A42:REMOTE SERVICE ALARM
This alarm indicates that a critical anomaly has occurred on the UPS. Where a maintenance contract with the Remote Monitoring option
is in place, the procedure for analysing the UPS via remote connection will be automatically activated by your service centre provider.
A44: PERIODIC SERVICE CHECK-UP
The equipment must undergo regular inspections by the support service in order to ensure optimum performance and e ciency. If
the Scheduled Inspection signal appears ( ) on the mimic panel the equipment should be inspected by a suitably trained technician.
A51: OPTION BOARD GENERAL ALARM
Check if the optional cards are correctly inserted in the slots.
A59: BATTERY CIRCUIT OPEN
Battery switch open.
A60: FAN FAILURE
Fault in the ventilation system. Check that the air inlet at the front and the air outlet at the back of the UPS are not obstructed.
8.3. PREVENTIVE MAINTENANCE
We recommend regular specialist maintenance (annually) for the MASTERYS BC, to achieve optimum operating e ciency and
avoid equipment downtime.
It is strongly advisable to comply with any requests for preventive maintenance automatically displayed with an alert message ( ).
All operations on equipment must only be carried out by SOCOMEC personnel or authorised support personnel.
Maintenance consists of accurate functional checks on electronic and mechanical parts with replacement of parts subject to wear
if necessary (typically batteries, fans and capacitors).
8.3.1. Batteries
The condition of the external batteries is fundamental to UPS operation.
Thanks to the Expert Battery System, battery condition information is processed in real time and recharging and discharging
procedures are selected automatically in order to optimise battery lifetime expectancy and o er maximum performance.
Furthermore, during the operating lifetime of the battery, MASTERYS BC stores statistics on battery conditions of use for analysis.
Since the expected lifetime of batteries is very much dependent on operating conditions (number of charging and discharging
cycles, load rate, temperature), a regular inspection by authorised personnel is recommended.
When replacing the batteries use the same type and configuration by placing them in the appropriate containers
so as to avoid the risk of acid leakage.
Used batteries must be disposed of at authorised recycling and disposal centres.
Do not open the plastic cover of the batteries as they contain harmful substances.
