Description
The GSCM-mini-P (Pulse) is a micro-processor based
generator start-stop module, designed to auto start-
stop generators that need a 3 to 4 wire connection
from a 2 wire 12 volt manual start command. The
GSCM-mini-P automatically goes into run mode
when it either receives a remote start indication
lamp signal (connected to terminal 8) or an AC Hz
signal from the generator (AC connected to terminals
9 & 10). Various LEDs are blinked or turned on to
indicated the run or fault status of the GSCM-mini-P.
Manually resetting the GSCM-mini-P by removing
the power and removes any lockout that allows the
generator to restart if called to do so.
The GSCM-mini-P is powered by 12VDC from the
generator battery and can monitor the battery
voltage and start the generator to charge its own
battery. The GSCM-mini-P is a limited function
controller that is part of the GSCM family.
All auto start battery voltage thresholds are
fixed, if adjustability is required use the GSCM
full function Generator Start Control Module.
