Safe Operation Mode - Manitowoc QuietQube Series Technician's Handbook

SAFE OPERATION MODE

Allows the ice machine to operate up to 72 hours if the
ice thickness probe (E19 fault) and/or water level probe
sensors fail (E20 fault).
• When the control board starts the safe mode an alert
is flashed on the LCD display to notify the end-user
they have a production problem.
• The control board automatically initiates and monitors
the safe mode. The control will automatically exit the
safe mode if a normal signal is received from the input.
• After 72 hours the control board will enter a standby
mode and turn off.
• The control board needs a five cycle history to operate
safe mode. If five cycles have never been successfully
completed the ice machine will shut-off.
