Troubleshooting
8.1
Fault and alarm indications
At the system control panel
If a system fault occurs, the audible alarm will sound and the
Warning
symbol will appear in the system control panel
header bar. In this case proceed as follows:
1. Silence the audible alarm by pressing the
RESET
button.
2. Identify the cause of the alarm by viewing the detected problem on the
EVENTS
screen
(see page 23)
.
3. If the fault relates to a UPS module the
Module
Selection
button on the display header bar will be red. If you press
the
Module
Selection
button the faulty module will be identified in the
MODULE
SELECTION
screen, as described
on page 31.
4. If the alarm event is shown in the table in paragraph 8.2, follow the actions provided in that table. If the event is not
shown in the table, or you have any doubts as to how to carry out the instructions given, then please contact Kohler
Uninterruptible Power Ltd. on 0800 731 3269 (24Hr.).
At the UPS module level
Fault events are displayed in date/time order on the module control panel as shown on page 16.
To access the module control panel events log:
1. Press the
UP
key once to access the menu system.
2. Use the
UP/DOWN
keys to move the cursor so that it is adjacent to
EVENTS.
3. Press the
ENTER
key.
4. Step through the logged events (up to 64) using the
UP/DOWN
keys and make a separate note of each alarm condition
as this will assist in identifying any problems.
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
RECT
FAULT
alarm
will activate and it may still indicate a fault condition even after the mains supply has returned to
normal.
If any of the following alarms appear, the first action to take is to attempt to
RESET
it.
•
MAINS
RECT

MAINS

If the alarm resets then it was probably caused by a transient condition and is no longer present; the
UPS has responded correctly and no further action is required. If it is not possible to reset the alarm,
or if the alarm is repetitive, investigative action is necessary which may require assistance from the
UPS Service department.
