ECOMMENDED ACTION
,
IF ANY
R This is the result of a brief variation in the bypass frequency. It is usually of no concern.
29.
Static switch is sending an
alarm or warning.
E
One of the bypass, inverter or output voltages may be out of range.
The inverter output voltage may not be synchronized to the bypass voltage
The bypass input frequency may be out of range.
Warning
R Perform the instructions in section
”.
30.
Static switch not responding. E There is a problem with communication between the controller and the static switch.
Warning
R
Is it just the STSW that isn’t communicating? Is data from the UPS modules being passed to the controller?
The controller may not be firmly seated in its shelf, resulting in a bad electrical connection with the
communication cable.
The controller may be frozen and needs to be rebooted.
Is the Alarm LED lit up?
Verify that the communication flat cable is connected firmly on the STSW and on the controller rear.
The STSW controller card (PC796) may need replacement.
31. Sync fault
(compare with “Short sync
fault”)
E A prolonged (minutes) loss of synchronization occurred between the bypass and the inverter frequencies.
Warning
R
This could be due to an unstable bypass source.
There may be a problem with the communication cable and its connection to the static switch.
If this problem occurs during first-time operation of the UPS, it could be due to improper phase order, or improper
definition of the bypass frequency (60 Hz instead of 50, for example. See “Setup > System > Nominal settings”).
32. Temperature fault.
E The battery temperature sensor has registered a temperature outside of the acceptable range (too high or too low). Measured temperature
can be seen on the “status” screen (tap on the battery icon).
Critical
R
The room’s air conditioning may need to be adjusted to lower the air temperature.
The temperature sensor may have malfunctioned.
The temperature alarm thresholds can be seen at “Setup > Alarms > Set limits > Temperature limits”.
See Table 3 on page 7 for recommended air temperature for optimal battery life.
33. The system is operating with E The system should have only 1 master module, yet the controller says there is more than 1.
