Signal Type Description
Power Raise J12-3
Discrete Open Collector Input - A pull
down to ground on this line indicates
that the Power of the System is to be
Raised.
(Low = Activate : Floating = No
Change)
Command
Power Lower J12-4
Discrete Open Collector Input - A pull
down to ground on this line indicates
that the Power of the System is to be
Lowered.
(Low = Activate : Floating = No
Change)
Command
System Interlock J12-5
Discrete Open Collector Input - A pull
down to ground on this line indicates
