High gearmotor amps – Stage 2
If the restart is successful the board will continue to monitor the current draw on P4 for 60 minutes looking for
a second high amps (above 3A) occurrence. If the ice machine runs without problems for 60 minutes and no
additional torque errors occur, the ice machine will continue normal operation.

High gearmotor amps – Stage 3
If a second occurrence happens during the 60 minute monitoring period, the HI AMPS LED will come on again
and shut the machine down (strike two). The HI AMPS LED (wihout the TIME DELAY LED) will indicate to the
technician that two consecutive over-torque situations have occurred. The ice machine is shut down at this time
and locked out. It will not restart unless the manual reset button is depressed while power is on.
