Troubleshooting
7.1 Alarms
A number of UPS operating parameters and conditions are monitored and will generate an alarm or warning event
notification on the UPS control panel if an error is detected or an abnormal condition occurs.
In the event of an alarm occurrence you should:
1. Silence the audible warning.
2. Identify the cause of the alarm by noting any recent events in the UPS module control panel ‘event’ register.
3. Interpret the cause of the alarm (see below) and seek assistance from your nearest service centre if the cause of the
alarm is beyond simple rectification.
7.2 Module control panel
The module control panel is described on page 21.
If an alarm condition occurs, the red
ALARM led will flash accompanied by an audible warning:
1. Cancel the audible warning by pressing the RESET button.
a) If the alarmed condition was transient the audible warning will stop and the red warning light will extinguish.
b) If the red warning remains ON it indicates that the cause of the alarm is still present and must be investigated.
2. Investigate the cause of the alarm by making a note of the
EVENT LOG
, which is accessed from the
MAIN MENU
– this
will present a list of time-stamped events that took place preceding the detected alarm. The module control panel
menu map is shown in Figure 2.18 on page 24.
3. Access the
MEASURMENTS
screen from the
MAIN MENU
and make a note of the UPS input, output, battery parameters
etc.
4. Refer to the following troubleshooting table for possible fault resolutions.
IMPORTANT NOTE
Certain alarm conditions may ‘latch-on’ even after the cause of the alarm is no longer present. For
example, if there is a brief mains failure during unattended operation the
MAINS FAIL
alarm will
activate and it may still indicate a fault condition even after the mains supply has returned to normal.
Similarly, a
LOAD ON BYPASS
alarm might have been caused by an inverter overload, and a brief
load transfer to bypass while the fault cleared.
If any alarm appears, the first action you should take is to attempt to
RESET it.
If the alarm indication resets then it was probably caused by a transient condition; the UPS has
responded correctly and no further action is required. Investigative action is necessary only if it is not
possible to reset the alarm or if the alarm occurrence is repetitive, in which case you should seek
advice or assistance from the Kohler Uninterruptible Power Ltd. Service Department.
