6.2Display Panel Message Interpretation

The following table lists the various messages displayed on the operator panel together with a description of their interpretation.

DISPLAY MESSAGE

INTERPRETATION

 

 

EMERGENCY STOP

INVERTER OFF OR FAILED

OVERTEMPERATURE

OVERLOAD

BATTERY C/B OPEN

OUTPUT C.B. OPEN

RECTIFIER OFF

OR

FAILED

This alarm indicates that the UPS was shut down by means of the local or remote (if fitted) emergency stop pushbutton which of course is normally due to operator action - investigate why the emergency stop pushbutton was pressed.

If the emergency stop pushbutton was not pressed then check the continuity of the remote emergency stop line (if fitted), and if no remote emergency stop line is fitted then check that a link is connected between terminals 3 and 4 of the UPS auxiliary terminal block.

This alarm is active whenever the inverter is not producing its correct output voltage; either because it has been switched OFF or due to an internal fault.

The alarm will accompany other alarms such as [OVERLOAD],

[LOAD ON BYPASS]

Overtemperature is sensed by a normally-closed thermostat (90º C operating) fitted to each inverter heatsink. If an overtemperature condition arises, the audible alarm will accompany this message - the inverter stops and load transfers to bypass after 3 minutes.

The inverter overload has an inverse load/time characteristic - i.e. it will accept 125% overload for 10 minutes and 150% for 60 seconds. If this characteristic is exceeded then the load transfers to the bypass supply, the inverter stops and the

overload alarm annunciates. The [OVERLOAD] alarm will annunciate as soon as the load exceeds 100 % of the UPS rating, and the load will transfer to bypass some time later - depending on the degree of overload present.

This is a status indication only. Note that UPS if operating with the battery circuit breaker open and the mains power fails then the UPS output will also fail together with load power. Also check battery fuses.

This is a status alarm. This output isolator must be selected ‘CLOSED’ at all times except when operating on the maintenance bypass supply.

This alarm is active whenever the battery charger (rectifier) is not producing its correct output voltage; due to either an input supply failure, an internal fault, or an open input circuit breaker.
