Safe Operation Mode - Manitowoc Indigo 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
NOTE: 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.
• Example - The ice machine is a new installation
and the water has not been turned on. The ice
machine will stop after five cycles with five long
freeze cycles and five water system faults in the
event log.
