Diagnostic sequence – Stage 8
If the restart is successful the 20M LED goes off, the 60 minute timer LED (60M) comes on. The 60M LED will
remain on for 60 minutes from restart. A lighted 60M LED tells the technician that the ice machine has
experienced an over-torque condition. If the ice machine runs without problems for 60 minutes and no additional
torque errors occur, the 60M LED will go off and the ice machine will continue normal operation.

Diagnostic sequence – Stage 9
The second error (2ND) LED will come on if an over-torque condition occurs while the 60M LED is still lighted.
The 2ND LED will indicate to the technician that two consecutive over-torque situations have occurred. The ice
machine will shut down at this time and lock out. It will not restart unless the manual reset button is depressed.
