59. Control Overview The power control module on VCC product is identical to that on non VCC product The power control module senses if it is connected to a VCC compressor and uses the appropriate algorithm The compressor can operate at speeds between 1590 and 4300 rpm inclusive On the Fisher 8 Paykel product we operate the compressor at a select number of different speeds between 1590 and 4300 rpm to reduce the variation in sound produced by the compressor An electronic module inverter connected between the power control module and the compressor controls the speed This it does by supplying a modulated DC 3 phase supply to the compressor Warning Permanent damage will occur if the compressor is directly connected to the AC supply line The power control module monitors amongst other things the refrigerator compartment temperatures via thermistors and the defrost cycle and from this information sends signals to the electronic module inverter to determine compressor speeds Whenever the compressor starts it is run at 2200 rpm for 2 5 seconds to establish lubrication and is then run at 1590 rpm for a further 27 seconds before changing to any other higher speed as requested by the power control module This is to provide a softer start before the compressor potentially ramps up to some higher speed Whenever the refrigerator is plugged in turned on and or after a defrost in the first cooling cycle the control will run the compressor after i

ECT RANGE RELA Auto Power OFF Li RESET y Output Voltage The measurement of an output voltage using a multimeter voltmeter will not give a valid reading in a no load state because once the inverter is unable to sense the motor inductance on its output it will cease to operate The best method would be to use a current probe connected to an oscilloscope and measure one of the output phases blue black or brown wires from the inverter while the inverter is still connected to the compressor While it is appreciated that oscilloscopes and current probes are not commonly available to service technicians it is not a valid test to even try to measure the output voltage and that is one of the reasons why we have introduced this type of inverter with the built in LED diagnostic feature 46 Compressor system fault suspected Disconnect power from the appliance Are winding 27 resistances Measure compressor winding OK resistance between phases Refer Section 1 for compressor specifications Megger test between compressor windings and compressor case Is insulation between windings and case OK Compressor windings damaged Replace compressor with new part Yes Measure VCC Signal and VCC Mains harnesses for continuity and inspect connectors for damage Are wires continuous Harness damaged and No p Replace harness with new connectors part undamaged
