2. HOW IS MAGNETIC CLUTCH ENERGIZED?
The general process until the magnetic clutch is energized is shown below.
Dual Pressure Switch º'ONº:
Refrigerant Condition (2.1 kg/cm2 (30 psi, 206 kPa) less than 27 kg/cm
2 (384 psi, 2,648 kPa))
Thermistor supplies temperature signal of evaporator to A/C amplifier.

Magnetic Clutch Relay º'ONº
Temperature Sensor ºONº:
Temperature of Temperature Sensor is less than 180
°C (356°F).
Magnetic Clutch ºONº
Revolution Detecting Sensor supplies RPM signal of compressor to A/C amplifier.
If compressor is not locked, magnetic clutch is continuously energized.
