System Installation
GMW-25 2-9
Pin Name Type Description
8 REMOTE
CONTROL
SELECT
DI Connect to Pin 31 to enable analog remote
control. Leave disconnected to disable analog
remote control.
Note: If the generator is in digital remote mode
(via 9-pin port for RS-232), it cannot
switch to analog remote mode until the
digital remote mode is disabled.
Therefore, setting this pin low will have
no effect until the digital remote mode is
disabled.
9 GENERATOR
FAULT (E)
DO Emitter side of isolated transistor switch. (See
Note 1)
Transistor ON - Generator fault
Transistor OFF - No fault
Signal Definition:
Generator Fault = generator overheat condition
or interlock broken.
10 INTERLOCK This pin should connect to Pin 35 to complete
the interlock chain.
If the interlock chain is broken, the AC contactor
will open.
External circuit should be capable of switching
100 mA at 24 VAC.
