Compressor Components
For split cooling models ONLY
•The actuator coil positions are dedicated.
•The coils can be disassembled to verify the wire
colors for proper reinstallation.
•The right-side coil can be identified by a blue
mark on the outside of the component or by the
presence of an “R” affixed to the coil. See Figure
64 (Motor Cooling Solenoid Actuators).
•The left-side coil can be identified by no mark
present or the presence of an “L” affixed to the
coil. See Figure 64 (Motor Cooling Solenoid
Actuators).

NOTE
Refer to Figure 58 (IGV Connections) for the location of the IGV connections.
3.13 IGV
3.13.1 Function
3.13.2 Connections
The IGV assembly consists of movable vanes
and a motor. The IGV assembly is a variable-
angle guiding device that is used to control the
capacity at low-load conditions. The IGV position
can vary between approximately 0% (closed/
perpendicular to flow) and 100% (open/parallel
to flow). The vane angle is determined by the
BMCC and controlled by the Serial Driver. The
Serial Driver, in turn, uses +15VDC to control the
IGV stepper motor.
1. The IGV assembly is bolted to the compressor
housing.
2. The compressor controller cable is held to the
IGV Motor feed through by the cable clip.
3. The compressor controller cable continues on
to the suction pressure/temperature sensor.
4. The suction pressure/temperature sensor is
connected to the IGV Housing.
5. IGV Position Indicator
