- 12 V Present
Green
Normal status: ON
ON when the -12 V from the Generator Command
Board 400PL1 is present.
OFF when there is a problem with the -12 V from
the Generator Command Board 400PL1. In this
case, proceed as follows:
• Check the status of the -12 V on the Generator
Command Board 400PL1 indicated by its green
DS11 LED.
If the DS11 LED is ON, change the cable between
the XJ1 connector on the kVmA Board and the
XJ5 connector on the Generator Command
Board 400PL1.
If the DS11 LED is OFF, check whether the -12 V
returns when you disconnect the cable between
the XJ1 connector on the kVmA Board and the
XJ5 connector on the Generator Command Board
400PL1.
If the problem persists (i.e. DS11 is still OFF),
change the Generator Command Board 400PL1.
