Safety LimitsIn addition to standard safety controls, the controlboard has two built in safety limit controls whichprotect the ice machine from major componentfailures.Safety Limit #1: If the freeze time reaches 60minutes, the control board automatically initiates aharvest cycle. 3 cycles outside the time limit = 1 hourStand-by Mode.Safety Limit #2: If the harvest time reaches 3.5minutes, the control board automatically returns theice machine to the freeze cycle. 3 cycles outside thetime limit = Safety Limit (must be MANUALLY reset).Safety Limit Stand-by Mode: The first time a safetylimit shut down occurs, the ice machine turns off for 60minutes (Stand-by Mode). The ice machine will thenautomatically restart to see if the problem reoccurs.During the Stand-by Mode the harvest light will beflashing continuously and a safety limit indication canbe viewed. If the same safety limit is reached a secondtime (the problem has reoccurred), the ice machinewill initiate a safety limit shut down and remain off untilit is manually restarted. During a safety limit shut downthe harvest light will be flashing continuously.Determining Which Safety Limit Stoppedthe Ice Machine: When a safety limit conditioncauses the ice machine to stop, the harvest light onthe control board continually flashes on and off. Usethe following procedures to determine which safetylimit has stopped the ice machine.1. Move the toggle switch to OFF.2. Move the toggle switch back to ON.3. Watch the harvest light. It will flash one or twotimes, corresponding to safety limits 1 and 2, toindicate which safety limit stopped the icemachine.After safety limit indication, the ice machine will restartand run until a safety limit is exceeded again.Part Number 80-01111-9 7/10 109
