4.18.2.9 SCR Temperature Sensor Installation - TTS300/TGS230
1. Carefully thread the SCR Temperature Sensor into the SCR Cooling Manifold and torque to 6 Nm (53
in.lbs.).
• • • CAUTION • • •
Be careful to not damage the wire exiting the SCR Temperature Sensor when tightening.
2. Carefully slide the sensor cable under the SCR Cooling Manifold from the discharge side of the
compressor
3. Connect the SCR Temperature Sensor to the Compressor controller Harness. Refer to Figure 4-148 SCR
Temperature Sensor Connector - TTS300/TGS230 on page 146.
4. Install the Terminal Block. Refer to Section 4.11.2.2 Specific 3-Phase Main Voltage Input Terminal Block
Removal - TTS300/TGS230 on page 102.
5. Connect the discharge pressure/temperature sensor connector if it was removed.
6. Continue to Section 4.18.2.11 SCR Temperature Sensor General Installation.
4.18.2.10 SCR Temperature Sensor Installation - TTS/TGS/TTH/TGH Rev. F and Earlier (Except TTS300/TGS230)
1. Carefully thread the SCR Temperature Sensor into the SCR Cooling Manifold and torque to 6 Nm (53
in.lbs.).
• • • CAUTION • • •
Be careful to not damage the wire exiting the SCR Temperature Sensor when tightening.
2. Connect the discharge pressure/temperature sensor connector if it was removed.
3. Install the SCR Temperature Sensor Cable in the same location. It should be on top of the SCR Cooling
Manifold and next to the Inverter. Refer to Figure 4-150 SCR Temperature Sensor Connector -
TTS/TGS/TTH/TGH Rev. F and Earlier (Except TTS300/TGS230) on page 147.
4. Connect the SCR Temperature Sensor Cable to the Compressor Controller Cable Harness.
5. Install the Capacitor and DC Bus Assembly and verify the SCR Temperature Sensor Cable is not pinched.
Refer to Section 4.21.4.4 DC Capacitor Bus Bar Assembly Installation - TTS/TGS/TTH/TGH (Except
TTS300/TGS230) on page 174.
6. Install the Terminal Block and AC Bus Bars. Refer to Section 4.11 3-Phase Main Voltage Input Terminal
7. Connect the Soft Start AC wires to the AC Bus Bars.
8. Continue to Section 4.18.2.11 SCR Temperature Sensor General Installation.
4.18.2.11 SCR Temperature Sensor General Installation
1. Install the Soft Start. Refer to Section 4.14 Soft Start on page 113.
2. Install the top covers. Refer to Section 4.1 Compressor Covers on page 52.
3. Return the compressor to normal operation.
