3.4 Alarms
With a connected PC, the following alarms are realised (SNMP and
service modes):
Rectifier Failure The Rectifier mains is in order but a failure is present within the
rectifier.
Inverter Failure The inverter is ON but the inverter voltage or inverter conditions
are not in order.
Battery Switch OFF The battery switch is OFF
Retransfer blocked The inverter has attempted unsuccesfully to take over the load at
least 5 times within 3 minutes.
To reset, press the "RESET" pushbutton a second time after
muting the alarm.
Overtemperature The inverter/rectifier components are operating at an excessive
temperature. This can be due to extreme environmental conditions
or a failure within the inverter or rectifier sections.
If the bypass is available the UPS transfers immediately to the
bypass supply (in the case of a hot-standby system, the second
unit takes over the load, in the case of a parallel system the re-
maining inverters take over the load). If the bypass or another
inverter is not available then the UPS will continue to supply the
load for a further 10 minutes before shutting down.
Mains Failure The mains is not present or not within the specified voltage and
frequency tolerances.
Inverter not Feeding The inverter is not feeding the load and the bypass static switch,
SSI is OFF.
Battery Discharging The mains or rectifier has failed and the batteries are
discharging.This alarm is activated at a battery voltage of approx.
360Vdc.
Low Battery The remaining battery capacity during discharge has been calcu-
lated to be less than 20% of the nominal capacity.
Battery Test Failed The routine battery test has detected a decrease in capacity of the
battery. The battery must be checked.
Paralleling Fault The inverter has failed to regulate correctly in parallel operation
with another inverter (parallel systems only).
Bypass not Available The bypass mains supply is OK but the bypass is not available to
take the load if the inverter fails (the inverter is not synchronised or
is blocked externally).
