Checking or Replacing Temperature
Sensors
The Carousel Plus W Series Dryer uses RTD sensors to monitor the temperatures of the
return air, the regeneration outlet, and the regeneration inlet. Your dryer may have (option-
al) a sensor for delivery air, process protection, and/or setback.
To check or replace an RTD sensors:
1
Disconnect and lockout the main power supply.
2
Remove dryer panels, as necessary.
3
Locate the RTD sensors.
4
Check the sensor positions and conditions.
Temperature readings will be incorrect if the
sensors are touching the wall of an air hose or pipe or if the sensor or wiring is dam-
aged. The tip of the sensor should be centered within the air hose or pipe. Sensor wires
should be attached to the appropriate connection points on the dryer’s electrical enclo-
sure or microprocessor board.
5
To check with ohm meter,
measure the resistance across the RTDs. The resistance
should be approximately 110 ohm at room temperature.
6
Replace the sensor, if necessary.
