Safety Limits
GENERAL
In addition to standard safety controls, such as the
high-pressure cutout, the control board has two built-in
safety limit controls which protect the ice machine from
major component failures. There are two control
boards with different safety limit sequences. The
microprocessor chip can identify the control boards.
Current production control boards have an orange
label on the microprocessor with the number 302. The
earlier version does not have the orange label.
Safety Limit #1: If the freeze time reaches 60 minutes,
the control board automatically initiates a harvest
cycle.
Control Board with orange label and 302 on
microprocessor.
If six consecutive 60-minute freeze cycles occur, the
ice machine stops.
Control Board with black microprocessor.
If three consecutive 60-minute Freeze cycles occur,
the ice machine stops.
