LED Description and Meanings
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
Generator Hz Shutdown:
Fast blink = over speed condition
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
Run:
Continuous = GSCM-mini has a valid run signal from generator
Fault:
Continuous = GSCM-mini is in a fault condition and requires a reset
K1 & K2:
Continuous = status of K1 and K2 relays on
