System Control
Control of the system is achieved by the cyclic action of the compressor's electromagnetic clutch. When current is fed to the field coil of the compressor's clutch, a magnetic field develops between the field coil and the armature which pulls the field coil, complete with clutch assembly, onto the compressor rotor. Since the clutch assembly is turned constantly by the crankshaft pulley drive belt, the compressor armature turns, starting the refrigeration cycle.
Current is fed to the field coil through three series switches whose contacts are controlled by the following:
1 The manual A/C ON/OFF switch A in the control console.
2 The freeze protection thermostat switch monitoring the evaporator temperature.The high and low level binary pressure switch.
The ON/OFF Switch A will start the refrigeration cycle provided that the ambient temperature in the cab is greater than the Thermostatic Switch cut out temperature and the refrigerant pressure remains within the specified Binary
Switch limits.
