GENERATOR EMERGENCY SHUTDOWN WITH THE GSCM-mini-D
SECTION - 7
The GSCM-mini-D Generator Start Stop module is
NOT AN EMERGENCY SHUTDOWN DEVICE!!
If the manual start signal is
removed the generator will go through a normal shutdown which may take up to 15 seconds to completely shutdown the generator.
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-mini-D
module will force the relays to open. This will shutdown generators that require a maintained run signal from K1 relay. However this
also prevents the K2 relay from closing to shutdown those generators requiring a momentary stop signal. Using a double pole “Kill”
switch and wiring the second pole in parallel with the K2 relay terminals will force the generator to stop in an emergency situation such
as a fuel spill. (see note 1 on wiring diagram, page 2, for Ignition/crank emergency shutdown option).
LED DESCRIPTION (WHAT THEY MEAN)
SECTION - 8
1.
Start:
one blink every 5 seconds = Ready mode, looking for a start signal;
one blink every 2.5 seconds = auto start mode operation;
one blink every other second= auto start/stop period,
continuous = manual start signal received;
fast blink = 60 second delay after start signal removed before generator started;
2.
Generator
Hz
fast blink = over speed condition;
Shutdown:
slow blink = under speed condition;
double blink = Maximum Crank attempts reached, Failed to Start;
triple blink = Auto start attempted with-in 30 minutes of a Max run time (6 hour ) shutdown;
Four blinks every 2 seconds = Ac Hz or 12v run status signal lost during run mode;
continuous = start function disabled, AC Hz detected while in ready mode;
3.
Run:
continuous = GSCM has a valid run signal from generator;
4.
Fault:
continuous = GSCM is in a fault condition and requires a reset;
5.
K1 & K2:
continuous = Status of K1 and K2 Relays “ON”
