Description
The GSCM-mini-d is a micro-processor based generator
start-stop module, designed to auto start-stop diesel
generators that need a 3 or 4 wire connection from a 2
wire 12 volt or dry contact manual start command. The
GSCM-mini-d automatically disconnects the starter
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-d. Manually
resetting the GSCM-mini-d by removing the power and
removes any lockout that allows the generator to
restart if called to do so.
The GSCM-mini-d is powered by 12VDC from the
generator battery and can monitor the battery voltage
and start the generator to charge its own battery if
connected to pin 4. The GSCM-mini-d 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.
