4.6 Solenoids and Coils
The solenoids pass the high-pressure liquid refrigerant to the low pressure motor and/or electronics cooling path.
4.6.1 Solenoid and Coil Connections
Solenoids are secured to the service side of the compressor housing in the upper left. Refer to Figure 4-28 Cooling
Figure 4-28 Cooling Valve Bodies
Solenoid orifice size will vary between compressor models. The size can be identified by reading the number
engraved into the solenoid orifice body. For solenoid identification by model, reference the Spare Parts Selection
Guide.
Solenoid actuator coils are secured to the solenoids by nuts tightened at the back of each actuator. Refer to Figure
4-29 Compressor Cooling Solenoid Coils.
24VDC Power is supplied to the Coils through the Backplane from the Serial Driver and controlled by signals from
the BMCC to the Serial Driver. The cable is connected to J16 on the Backplane. Refer to Figure 4-31 Backplane - J16
