The refrigeration cycle is continuous;...

  • Page 13: Water System

    Water system The water level in the evaporator is controlled by a feed solenoid and level detecting sensors. Referencing the diagram below, water sensing rods extend down into the reservoir at the end of the evaporator assembly. The system works via electrical conductivity as follows: One of the longest probes is a common.

  • Page 14: Electrical System

    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 green light labeled POWER indicates power to the machine.

  • Page 15: Test Points

    Test points: The Horizon PC board incorporates on-board test points that can be used to determine various electrical outputs. The test point holes allow a standard probe to be inserted for quick voltage measurement. For 208-230 systems, use TP-4 (L2) as the common for testing outputs for solenoids, motors, etc. Error faults: The Horizon PC board monitors various operating parameters including high pressure, auger gearmotor amperage limits, clogged drain, and high and low water alarm conditions.

    “Bin full” detection system The Follett Horizon icemaker incorporates a unique “bin full” detection system that consists of the shuttle and actuator. The shuttle incorporates a fl ag and sensor. Referencing the fi gure below, the normal running position of the fl ag is down, out of the sensor. When the bin fi lls to the top and ice can no longer move through the tube, the machine will force the shuttle fl ag up into the sensor, shutting the machine off.
