DESCRIPTION
The GSCM-mini is a micro-processor based generator start-
stop module, designed to auto start-stop high speed gas
generators needing a 3 wire connection from a 2 wire manual
start command. It automatically disconnects the starter when
a minimum generator AC Hz. output is measured. It can
monitor the generator's output for an over or under Hz
condition and shut it down if either is detected. The Gen. Hz
LED is blinks to indicate the cause of the shutdown. Manually
resetting the GSCM-mini by removing the power, removes any
fault shutdown and allows the generator to restart if called to
do so. The GSCM-mini is powered by 12VDC from the
generator battery, and can monitor the battery voltage and
start the generator to charge it's own battery. All Thresholds
are fixed. The GSCM-mini is a limited function controller, part
of the GSCM family. If adjustability is required use the GSCM
full function Generator Start Control Module.
THREE MODES OF RELAY OPERATION
The GSCM-mini's two relay contacts can be configured for
three types of three wire start/stop hook-up configurations;
momentary, maintained and Ignition for Hondas, Onans,
Yamahas, and other brands of generators.
accomplished with an optional jumper on terminal 6.
Momentary Start Contact Option #1, terminal 6, has No
Connection. The GSCM-mini defaults to a momentary crank
operation for those generators that use two momentary push
button switches to start and stop the generator. K1 cranks the
Starter and K2 momentarily grounds the magneto. See
Section 1 for operation description.
Maintained Start Contact Option #2, terminal 6, is
grounded. The GSCM-mini changes to a maintained start
operation for generators that use a maintained closed contact
to start (K1). The generator is stopped by opening K1 and
closing K2 contact, momentarily grounding the magneto. See
Section 2 for operation description.
Ignition Key Switch Start Contact Option #3, terminal 6, is
connected to B+ (12VDC). The GSCM-mini simulates an
automobile ignition switch, K2 closes, maintains a closed
ignition contact for the generator to run and K1 closes
momentarily to crank the starter motor. and de-energizes
when the start signal is removed. The K1 relay operates in a
momentary crank configuration. See section 3 for operation
description.

LED INDICATION DESCRIPTION
The GSCM-mini has six indication LEDs. The Start LED, blinks
every 5 seconds to indicate ready for a start signal, blinks every
2.5 sec. to indicate running in Auto Start mode, 'On' continuously
indicates running in Manual Start mode.
The Generator Hz LED, blinks to indicate over/under Hz Fault
and Start Failure do to Maximum crank attempted. A slow blink
indicates an under Hz condition, a fast blink indicates an over Hz
condition. 'On' continuously indicates AC present in a non run
condition. A double blink indicates a start failure condition. The
Run LED, 'On' continuously indicates a valid Run signal from the
generator. The Fault LED,'On' indicates a Fault condition has
occurred and GSCM is in lockout and must be reset. The K1
and K2 LEDs indicate the relay status.
OPERATIONAL THRESHOLDS
The GSCM-mini has fixed operational thresholds. Those are:
Crank delay, Maximum Crank time, Crank Hz. Disconnect,
Under Speed Shutdown, Over Speed Shutdown, Max auto start
This is
run time, and auto detects the Battery voltage to determine the
auto start and auto stop threshold values for 12V, 24V, and 48V
battery systems. If adjustability is required then use the GSCM
full function control module.
