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

 

FAULT

MAINS

 

BYP

BYPASS

OK

BYPASS

 

IS

 

NOT

 

OK

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.
