Automatic Shut-Off; Restart After Automatic Shut-Off - Manitowoc QuietQube Indigo Series Technician's Handbook

AUTOMATIC SHUT-OFF

7. Automatic Shut-Off
Ice Machine Section: Shuts off when:
• The storage bin is full at the end of a harvest
sequence.
• The sheet of cubes fails to clear the water curtain
and holds it open.
• Ice damper is held down.
• Bin level probe thermistor senses setpoint (when
used).
After the water curtain or ice damper are held open for
30 seconds, the ice machine shuts off. The ice
machine remains off for 10 minutes before it can
automatically restart.
ICVD Condensing Unit: The liquid line solenoid valve
closes and the condensing unit pumps down. The
LPCO opens and signals the control board. The
control board starts a ten minute delay period and
opens the 24 VAC circuit to the contactor coil, stopping
the compressor and condenser fan motor.

RESTART AFTER AUTOMATIC SHUT-OFF

The ice machine remains off until enough ice has been
removed to allow the ice to fall clear of the water
curtain or ice damper. As the water curtain or ice
damper swings back to the operating position, the bin
switch re-closes and the ice machine restarts (steps 1
- 2), provided the 10 minute delay period is complete.
