2.9 LCD Messages

This section presents the most common alarm messages that appear on the LCD (the alphanumeric section of the “hidden” panel), and explains their meaning.

LOAD IS PROTECTED

UPS IS ON LINE

This is the normal display message. There are no alarms or problems, and the load is being supplied by the UPS inverter.

2.9.1General Alarms

LOW LEVEL ALARM

UPS OK !

This message indicates that a problem requiring action has occurred. The load is still supplied by the inverter. The problem is listed in the secondary alarm message (see below), as indicated by the flashing exclamation mark (!). The alarm message may be viewed by pressing the “alarm” pushbutton (!)

UPS INPUT FAILURE

LOAD ON BATTERY !

This message indicates that the main AC input (mains 1) has failed or is outside of tolerance, and power to the inverter is being supplied from the UPS battery system. The load is still supplied via the inverter.

REMAINING BAT. TIME __ MN %KW LOAD = __

This message is automatically displayed every five seconds when the UPS is on battery. It alternates with the previous message. The message provides an estimate of the available remaining time on battery, based on the percentage of full rated load being supplied, the type of battery, the battery temperature, and the battery age.

UPS LOW BATTERY

SHUTDOWN IMMINENT !

This message indicates that the batteries have reached the “low battery shutdown” warning level. The user must take steps to prepare the load for shutdown (load shedding, file saving and computer shutdown, etc.). This message replaces the previous two messages when the batteries are nearly depleted. When this message appears, there are only a few minutes of battery back-up time remaining.

UPS ALARM

CALL SERVICE !

This indicates that the battery disconnect circuit breaker QF1 has been open or the inverter has stopped and that service is required. The problem is listed in the secondary alarm message (see below), as indicated by the flashing exclamation mark (!). The secondary alarm message may be viewed by pressing the “alarm” pushbutton (!).

2.9.2Secondary Alarms

The presence of these alarms is indicated by a flashing exclamation mark (!) on the general alarm message. Press the “alarm” pushbutton to view these messages.

EMERGENCY SHUTDOWN

REPO ON !

This message indicates that the UPS has been shut down because a remote emergency power off (REPO) pushbutton has been pressed and is still closed.
