Safety Limit Feature - Welbilt Manitowoc NEO UDE0065A Technician's Handbook

SAFETY LIMIT FEATURE

In addition to the standard safety controls, your
Manitowoc ice machine features built-in safety limits that
will stop the ice machine if conditions arise which could
cause a major component failure.
Safety Limit #1: If the freeze time reaches 60 minutes,
the control board automatically initiates a harvest cycle. 3
cycles outside the time limit = 1 hour Stand-by Mode.
Safety Limit #2: If the harvest time reaches 3.5 minutes,
the control board automatically returns the ice machine
to the freeze cycle. 3 cycles outside the time limit = Safety
Limit (must be MANUALLY reset).
Safety Limit Stand-by Mode: The first time a safety limit
shut down occurs, the ice machine turns off for 60 minutes
(Stand-by Mode). The ice machine will then automatically
restart to see if the problem reoccurs.
During the Stand-by Mode the harvest light will be flashing
continuously and a safety limit indication can be viewed.
If the same safety limit is reached a second time (the
problem has reoccurred), the ice machine will initiate a
safety limit shut down and remain off until it is manually
restarted. During a safety limit shut down the harvest light
will be flashing continuously.
