Overview How the machine works Follett’s automatic-load ice machine is equipped with Follett’s 400 lb (181kg)/day ice technology. In the continuous icemaking process, water freezes to the inside wall of the evaporator. A rotating stainless steel auger carries the ice to the top of the evaporator where it is compressed and extruded through an outlet port. -

Service –––––––––––––––––––––––––––––––––––––––––––––––––– (continued) Electrical system Normal control board operation The PC board indicator lights provide all the information necessary to determine the machine's status. Green indicator lights generally represent “go” or normal operation; Yellow indicators represent normal off conditions; Red indicators generally represent alarm conditions, some of which will lock the machine off. A flashing green light labeled POWER indicates power to the machine. - Page 20 A soft error can either be automatically reset should the condition rectify, or if power is cycled. Should an error occur, consult the troubleshooting guide in this manual or a Follett service technician. Soft errors: HI AMPS: The PC board monitors the amperage of the auger motor. Should the gear motor experience current draw above the allowable limit, the machine will shut down and the TIME DELAY and HI AMP will be illuminated.
