GSCM-mini-P Option #1
Power/start/stop
The GSCM-mini-P accepts Outback's 2 wire switched 12VDC start /run signal or a dry contact, like Samlex, Trace and others,
it produces a 3-4 wire start/stop signal for most gas and propane generators. Using the generators remote port and remote
pilot lamp (PL) signal, if available, can make for a quick and easy instillation, otherwise it is wired in parallel with the power
and push to start/stop switch. The Pilot Lamp signal or 120/240VAC provides feedback telling the GSCM when the generator
has started and when the generator has completely shut down. A red connector with a protection diode is provided to
connect between terminal 8 on the GSCM-mini and pilot lamp wire for applications where the pilot lamp signal is positive
or high. If the pilot lamp signal is negative or goes low the pilot lamp signal inverter must be used, see Inverter Style
Generator. The GSCM-mini-P's configuration terminal # 6 has not connection, the starting sequence is as follows:
1. The start LED blinks once every 5 seconds to indicate that the GSCM-mini is in a "ready" mode. When a manual
signal is received, the start LED lights continuously. After a 2 second delay, the K1 relay provides a 1 second pulse
to wake up the generator's ECU, then after a second 2 second delay it provides another 1 second pulse to initiate
the ECU's starting sequence. The Champion's ECU will provide up to six starting attempts.
2. If the generator fails to start during six starting attempts and rest periods, approximately 90 seconds, the GSCM-
mini-P provides a 1 second pulse on the K2 relay to ensure the generator is not running and then enters the failed
to start fault. The Generator Hz LED does a double blink, the fault LED turns on and the GSCM-mini enters the
maximum crank lockout fault condition. This lockout condition remains until the GSCM-mini is reset by removing
power from terminal 2, waiting 5 seconds and then reconnecting power (see GSCM-mini wiring diagram, page ??).
This clears the lockout condition, and the GSCM-mini re-enters "ready" mode with the start LED blinking every 5
seconds.
3. When the generator starts, the GSCM-mini-P's green Run LED turns on, indicating that it received a valid run signal.
A valid run condition is determined by one of two conditions: A 12V run status pilot light signal provided by the
generator connected to terminal 8, or by generators AC output frequency exceeding the crank disconnect setting of
45Hz (terminals 9 & 10).
4. If the generator starts but shuts down after a few seconds due to a fuel problem, etc., the GSCM-mini-P exits the
run mode, energizing the K2 relay for 1 second, then enters a 60 second delay period blinking the yellow start LED
rapidly, then returns to "ready" mode. The GSCM-mini-P will then try to start the generator again in manual mode
or after a 5 minute delay period in auto-start mode.
5. If the generator starts but shuts down after the 60 seconds stabilization period, due to a fuel problem, low oil
pressure, broken AC Hz or 12V run status wire, the GSCM-mini-P exits the run mode, energizing the K2 relay for 1
second, then turns on the Red Fault LED and blinks the generator Hz orange LED 5 times with a 2 second delay
between blinks. The GSCM-mini enters a fault shutdown lockout condition and must be powered down to reset the
fault lockout.
6. When a run condition is detected, the GSCM-mini turns on the green run LED and transistor output (remote run
lamp terminal 11).
7. If no faults occur, the generator will continue to run until one of the following occurs: The manual start signal is no
longer received and the auto battery charge voltage or maximum auto run time has been reached, while running in
auto charge mode over Hz condition, under Hz condition occurs if the generator over/under Hz shutdown is enabled,
or the generator runs out of gas
