Cam Switch Adjustment

Check the cam switch for proper adjustment by slowing turning the clutch by hand in a counterclockwise direction while listening for the switch contacts to change. The switch should have an audible “click” as the roller reaches the high part of the cam. Now slowly turn the clutch in a clockwise direction and the switch should have an audible “click” as the roller reaches the low part of the cam. Adjust the switch by loosening the mounting screws and moving the position of the switch. If the cam switch is suspected of being defective it should be checked with an ohmmeter. It should not be assumed that the switch is good because a “click” can be heard when moving the actuator arm.

High Temperature Safety Control The high temperature safety control is a thermal disc that protects the

machine if the machine “sticks” in the harvest cycle. The high temperature safety is clamped to the suction line near the expansion valve thermal bulb.

It opens when the suction line temperature reaches 120ºF (48.8ºC) and closes when the temperature drops to 80ºF (26.6ºC). If the high temperature safety opens during harvest, it will de-energize the harvest components. If the high temperature safety is defective and fails open during the freeze cycle, it will not allow the relay(s) to energize and the machine will not enter harvest. Remove the high temperature safety control and check it with an ohmmeter to verify that it is defective.

Note 1: ICE0500R3, ICE0606R3, ICE0806R3 and ICE1006R3: The high temperature safety control specifications have been changed to open at 120ْ F and close at 100ْ F.

Note 2: On models where the high temperature safety control is mounted on the hot gas valve outlet tube, the specifications are open at 180ºF and close at 120 ºF.

Additionally the high temperature safety control is wired in series with the contactor. If the high temperature safety control opens for any reason, the compressor will shut down. This is an automatic reset control. Do not allow the machine to operate without the high temperature safety control. Damage to the machine may result and the warranty will be void.

Bin Control Operation

The bin control is used to shut the machine off when the bin fills with ice. The bin control must be checked upon installation or initial start-up and when performing maintenance. Adjustments are

not covered under warranty.

There is one bin switch for each evaporator. The actuator arm of the bin switch comes in contact with the splash curtain. When the bin is full of ice, the splash curtain is held open when ice drops off of the evaporator. This releases the pressure of the bin switch actuator arm allowing the switch to open.

Single evaporator machines: If the bin switch opens during freeze, or the first part of harvest, relay 2 bypasses the bin switch and the machine will continue running. If the bin switch is opened during harvest, when the cam switch is lifted onto the high part of the cam, the machine will shut off. When the bin switch closes again, the machine will restart.

Dual evaporator machines: If either bin switch opens during the freeze cycle, the machine will shut off. Relay 1 and relay 2 will bypass the bin switches during defrost. If either bin switch is open when the machine returns to the freeze cycle, the machine will shut off.
