9.1 UPS SYSTEM ALARMS.
Overload in output supply. •
The load power draw is greater than the system’s nominal output.
Check the load on the display and disconnect loads not requiring UPS service or distribute the total load over the
three phases.
IMPORTANT!
Overloading results in the load not being powered by the UPS for a limited period of time. For further details, see
the technical specifi cations.
Switching inhibited. •
Switching from system bypass to inverter may be inhibited by an inverter failure. Reset the alarm and contact
Aftersales Service.
UPS switching not possible. •
Switching from system inverter to bypass is prevented by problems on the auxiliary mains supply: mains supply
out of tolerance, not synchronised, etc. Ensure that Q4 is closed, that the auxiliary mains supply is available and
that the values are within range.
Insuffi cient UPS resources. •
The system is in overload, with auxiliary mains supply and inverter inhibited. The power supply to the load will be
interrupted if the load is not brought back within range or the auxiliary mains supply fails. Check the load on the
display and disconnect loads not requiring UPS service or distribute the total load over the three phases.
Loss of UPS redundancy. •
In case of a parallel redundant system, loss of redundancy is due to possible problems with one of the units. Check
values and alarms status of all units, and make sure that none of the operating units is overloaded.
T.SERVICE alarm. •
Aftersales Service has activated a remote UPS analysis procedure (if the T.SERVICE contract is active).
General UPS alarm. •
This alarm is generated if at least one alarm is present on at least one unit. Check the other active alarms for
details.
General alarm modules 1…6 •
These alarms are generated if at least one alarm is present on unit 1 to 6 respectively. Check the other active alarms
for details.
