Green Power
100-120 kVA
Operation for an extended period of time at high temperatures (degradation of the batteries);
-
large number of overloads (incorrect sizing);
-
continuous battery draining (unstable mains voltage);
-
large number of circuit breakers on the bypass (high peak loads).
-
Bypass maintenance alarm.
•
This alarm is generated if circuit breakers Q5 (bypass) and Q3 (output) are closed at the same time. Check the
position of the circuit breakers.
Phase cycle fault.
•
The phase cycle of the auxiliary mains is incorrect. Swap two input phases or two phases of the auxiliary mains
supply (only for UPS with separate auxiliary mains supply).
Input mains supply not present.
•
The input power supply or auxiliary mains supply has failed or is insuffi cient (voltage/frequency out of tolerance).
Check for “rectifi er input power fault” and “bypass power supply out of tolerance” to identify the failure.
Check that the voltage and frequency values are in range (see technical specifi cations).
If there is no input mains supply failure, check whether the upstream protections have tripped or whether circuit
breaker Q1 (input power supply) is open.
If there is no auxiliary mains supply failure, check whether the upstream protections have tripped or whether
circuit breaker Q4 (auxiliary mains supply) is open.
General unit alarm.
•
This alarm is generated if at least one alarm is present on the unit. Check the other active alarms for details.
Genset alarm.
•
The genset has sent an alarm; check the genset.
Optional board alarm.
•
This alarm is generated if one of the optional boards is no longer communicating with the UPS controller. Check
that the board is correctly mounted and reset the alarms.
External alarm 1,2,3,4.
•
An ADC board input has been activated; check the devices connected to the board.
