s. Temperature sensors Pt100 or Pt1000
RC2 models utilize suction return gas to cool down the motor coil. To effectively detect temperature of motor coil
and adequately adjust volume of liquid injection by measured temperature, Hanbell specially mounts Pt100 or
Pt1000 sensor on motor coil as an optional accessory. This temperature sensor along with controller of the system
monitor motor coil temperature and then control on/off of liquid injection valve accordingly to provide suitable liquid
injection as shown in the diagram below.

1. Note: Hanbell suggests to control temperature of motor coil at 60℃ (not higher than 60℃)
2. On the terminal cover plates, “A” is PTC sensor, and “B” is Pt1000 or Pt100 temperature sensor.
3. The terminal cover plates for models RC2710B, RC2790B, RC2830B, RC2930A, RC2930B are
shown above. The PTC sensor is on the top right side and Pt1000 or Pt100 is on the left bottom side of
terminal cover plate.
