Ground Fault

A short between any circuit and earth ground will result in the following:

1)Activation of trouble relay contacts, trouble LED in a flashing mode, and local buzzer.

2)Operation of any output circuits which have been described as TROUBLE BELL.

3)“TROUBLE” and “GROUND” displayed on LCD.

Loss Or Reduction Of AC Power

A reduction in the AC input voltage will result in the following:

1)Activation of amber trouble LED in a flashing mode and local buzzer.

2)Operation of any output circuits which have been described as TROUBLE BELL.

3)“TROUBLE” and “A.C.” displayed on LCD.

4)LCD Backlight will be extinguished.

5)Loss of green AC LED.

6)The trouble relay contacts will transfer after 90 minutes.

Low Battery Voltage

Loss of or reduction of battery voltage to 22 volts will result in the following:

1)Activation of common trouble relay contacts, amber trouble LED in a flashing mode and local buzzer.

2)Operation of any output circuits that have been described as TROUBLE BELL.

3)“TROUBLE” and “BATTERY” displayed on LCD.

Loss Of Auxiliary Power Output

Loss of output of the auxiliary power will result in the following:

1)Activation of trouble relay contacts, trouble LED in a flashing mode and local buzzer.

2)Operation of any output circuits that have been described as TROUBLE BELL.

3)“TROUBLE” and “AUX LOW” displayed on LCD.

4)Activation of amber POWER TROUBLE LED.

5)Activation of amber SYSTEM TROUBLE LED.

To Silence The Buzzer Or Outputs That Have Been Described As Trouble Or Supervisory Bell

Press the scroll up or scroll down buttons. Once all events in the trouble or supervisory queue have been viewed, the buzzer and appropriate output will silence. The applicable system TROUBLE or SUPERVISORY LED will change from flashing to steady. Note: Any continuous trouble conditions that have been silenced automatically resound 24 hours after the first trouble condition was silenced.
