overload present.
7. OVERLOAD SHUTDOWN This message informs the operator that the load has been
transferred to bypass due to an inverter overload.
8. OUTPUT SWITCH OPEN This is a status alarm. The output switch must be selected
‘CLOSED’ at all times except when operating on the Maintenance
bypass supply.
9. BYPASS SWITCH OPEN This is a status alarm. The bypass input switch must be closed all
the times.
10. BATTERY C.B. OPEN This is a status indication only. Note that if the UPS is operating
with the Battery circuit breaker open, and the mains power fails,
then the UPS output will also fail together with load power, since
the inverter has no battery backup.
11. BATTERY: FUSE FAIL This problem should be rectified as soon as possible. If the mains
power fails then the UPS output will also fail together with load
power, since there is no battery backup.
12. BATTERY: TEST FAILED The system has carried out a test of the battery. If this alarm is not
accompanied by a [BATTERY C.B. OPEN] or [BATTERY: FUSE FAIL]
message then a full check of the Battery bank is required.
13.
DC BUS: UNDERVOLTAGE
When the inverter is operating on the battery this message is
displayed on the condition when battery voltage has fallen below a
preset value. If the input a.c. power cannot be restored, you should
shut down your loads.
