Confirm Operation of Alarm Wiring
After the converters are recognized to be in a normal state, one should confirm the proper operation of
the alarm contact closures. If alarm wiring is correct:
1. The loss of A or B input power should result in the assertion of a Power Minor.
2. The loss of both A and B input power, which will result in a loss of service, should result in a Power Major and a
Power Minor.
3. If a controller is installed in the system then it will indicate an alarm state by red display backlight. Using the
buttons on the keypad specific alarms can be retrieved by pressing the Back Arrow, . When the system
returns to normal function the display will be green.
