8. TROUBLESHOOTING
8.2. UPS
ALARMS
• A01: BATTERY ALARM
Failure or problem on the battery circuit. Check the battery switch is closed.
• A18: OVERLOAD OFF INV
Reduce the load rate applied to the UPS and reset the alarms.
• A20: WRONG CONFIG.
Error in the configuration parameters; contact the support service.
• A30: OVERLOAD STOP
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: SERVICE CHECK
The equipment has to undergo regular checks by the support service in order to ensure optimum performance and efficiency. If
the Scheduled Inspection signal appears on the mimic panel, the equipment should be inspected by a suitably trained technician.
• A59: BATT.CIRC. OPEN
Battery switch open.
• A60: FAN FAILURE
Fault in the ventilation system; check the air inlet at the front and the air outlet at the back of the UPS are not obstructed.
8.3. PREVENTIVE
MAINTENANCE
Please note that specialist regular maintenance (annually) is recommended for the MASTERYS BC to provide optimum operating
efficiency and avoid equipment downtime.
It is strongly advisable to give due consideration to any instructions to perform preventive maintenance displayed automatically
with alarm message M29 (refer to chapter 5).
All operations on the 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 battery is fundamental to UPS operation.
Thanks to the Expert Battery System, the information relating to the battery status and conditions of use are processed in real
time and recharging and discharging procedures are selected automatically in order to optimise battery life expectancy and offer
maximum performance.
Furthermore, during the operating life of the battery, MASTERYS BC stores statistics on the conditions of use of the battery for
analysis.
Since the expected lifetime of the batteries is very much dependent on operating conditions (number of charging and discharging
cycles, load rate, temperature), a regular check by authorised personnel is recommended.
When replacing the batteries use the same type and configuration by placing them in appropriate containers 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.
