Checking or Replacing Temperature Sensors

The D carousel dryer uses RTD sensors to monitor the temperatures of the drying air, the return air, the regeneration exhaust, and the regeneration and process heater boxes.

To check or replace an RTD sensors:

1

2Remove dryer panels, as necessary.

3Locate the RTD sensors.

4Check 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 sen- sor or wiring is damaged. 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 enclosure or microprocessor board.

5To check with ohm meter - measure the resistance across the RTDs. The resistance should be approx. 110 ohm.

6Replace the sensor, if necessary.

IMPORTANT: Always refer to the wiring diagrams that came with your dryer to locate specific electri- cal components. Illustrations in the User Guide are intended to be representative only.
