Running Check
1. Before starting the compressor, with the power on, using the SMT, verify Stator temperature
reading is an acceptable value.
2. While the compressor is running, verify the Stator temperature fluctuates to expected values
during operation.

3.7.1.13 High and Low
Pressure Temperature
Sensors
The high and low pressure temperature sensors (Figure 122 (High and Low Pressure Temperature
Sensors)) are used to signal the operating pressures and temperatures at the suction and discharge
ports to the CCM. These values are used to calculate pressure ratios and saturated temperatures. The
high and low pressure temperature sensors are located just behind the suction and discharge anges.
Refer to Figures 123 (Suction Temperature Sensor Location) and 124 (Discharge Temperature Sensor
Location) for further details on the exact locations.
