6. Resetting the GSCM for 60 seconds by shorting terminals 7 and 8 while in the ready mode forces the GSCM back to the
original factory default settings, as it came out of the box. The adjustment LEDs blink once in sequence to indicate a
return to default settings.
7. An alternate set of test adjustments may be selected by performing step 5 above and holding down the change/ store
button just before releasing the 60 second reset. The change/ store button is then released after the reset jumper is
removed, three of the ten adjustment LEDs blink. The test parameters are:
Maximum crank = 7 seconds - load delay = 20 seconds - pre-cool off delay = 10 seconds
Battery cut-in delay = 1 minute - battery cut-out delay = 2 minutes- 12 hour run time = 1 hour
To exit the test parameters operation the user must perform step 5 above to return to factory defaults.

Generator Emergency Shutdown with GSCM
The GSCM Generator Start Controller is NOT AN EMERGENCY SHUTDOWN DEVICE!! Shorting the reset terminals 7 and 8
terminates the current GSCM cycle. See GSCM RESET CONDITIONS section. If the manual start signal is removed the generator will
go through a normal shutdown which may include running for up to two minutes in a load removed cool-down cycle. Also shorting
reset terminals 7 and 8 will shut down the generator in a normal sequence including the cool-down cycle. If the generator has
started but is in the load delay period, applying a reset to terminals 7 and 8 will shut down the generator immediately.
A RECOMMENDED EMERGENCY SHUTDOWN SOLUTION is to install a separate "Kill" switch and label it as such. The recommended
wiring is shown on page 2 of these instructions and also in application 1. Disconnecting the power to the GSCM module will force
the relays to open. This will shut down generators that require a maintained run signal from K3 (ignition) relay. However this also
prevents the K4 (shutdown) relay from closing to shut down those generators requiring a momentary stop signal. Using a double
pole kill switch and wiring the second pole in parallel with the K4 (shutdown) relay terminals will force the generator to stop in an
emergency situation such as a fuel spill.

Continuous = manual start signal received
One blink every 5 seconds = ready to receive a command
Slow blink = auto start mode operation
Fast blink = 60 second delay after reset, before ready mode
Fast blink = over speed; slow blink = under speed
Continuous = start function disabled, AC Hz detected
Three slow blinks = run fault, loss of AC feedback signal after load relay has energized
Fast blink = high temperature; slow blink = low oil pressure
Fast blink = max. 4 crank attempts exceeded; slow blink = 12 hour max. runtime exceeded
On continuous = selected for adjustment
Blinking = entered crank delay period while glow plug relay K1 energized
Blinking = generator running, delay period before load transfer
Blinking = load disconnected, cool down period before shutdown
Blinking = battery voltage lower than cut-in point, during 5 minute delay
Blinking = generator Hz (over speed) greater than trip point, during 10 second delay
Continuous = adjustment selection; no blinking condition
One blink every minute = 30 day exercise option activated;
Fast blink = 60 second warning before 30 day exercise generator starting
