9. TROUBLESHOOTING
The system log (option "4 – HISTORY" on the main menu) can be very useful in determining the cause
of a UPS malfunction. See section
5.4 "Retrieving History (LOG of Events)" on page 62.
The indicator lights on the UPS module's front panel can also signal a malfunction.
Figure 9-1: UPS module front panel
As shown in Figure 9-1 there are three LEDs on the front panel of each UPS module: Alarm,
Output and Line. The internal buzzer in the UPS module sounds when there is no
communication with the system controller.
These 3 LEDs and the buzzer indicate the status of the UPS module (see
Table 9-1 below).
The alarm LED is red, line and output LEDs are green.
Normal condition is indicated by the green line LED and output LED on, with no beeps from the
buzzer.
