Option 1 Momentary Start Contact
The GSCM-mini-d option 1 provides the same momentary glow plug operation for those 3 wire diesel applications where the key switch or
off button is pressed for 10 seconds energizing the glow plugs, then the start button is pressed starting the generator. The GSCM-mini-d
energizes K2 for 10 seconds to heat the glow plugs, then energizes K1 relay, providing the start signal to start/crank input and removes it
when the generators AC output has reached 45Hz or half speed. The K2 relay also provides a momentary stop signal until the generator AC
Hz has dropped to zero. For operational sequence details see page 6, option 1.
Option 2 Maintained Start Contact
The K1 relay provides a continuous run signal for generators
requiring a maintained start signal. The K2 relay provides a
momentary stop signal until the generator AC Hz has dropped to
zero. For GSCM-mini operational sequence details see page 7,
option 2.
Option 3 Ignition Key Switch Type Start Contact
The K1 relay is used to switch the starter input that is looking for a momentary signal and opens it when the AC line output has reached
45Hz. The K2 relay provides a continuous run signal for generators requiring a maintained ignition signal. When the GSCM-mini no longer
receives a run command, K2 relay opens telling the generator to shut down. For GSCM-mini operational sequence details see page 8,
option 3. A single pole kill switch wired and installed by the user, stops the generator instantly in emergency situations such as a fuel
spill. One switch pole (N.C.) kills power to the GSCM-mini opening all relays shutting down the ignition switch type generators.

Typical Generator with Starter Control Box
Typical Generator with Starter Control Box
A double pole kill switch wired and installed by the user, stops
the generator instantly in emergency situations such as a fuel
spill. One switch pole (N.C.) kills power to the GSCM-mini
opening all relays. The other switch pole (N.O.) shorts out the
magneto for an instant stop.
