The Carousel Plus D Series Dryer uses RTD sensors to monitor the temperatures of the return
air, the regeneration outlet, and the regeneration inlet. Your dryer may have (optional) a sen-
sor 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 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 micro-
processor board.
5
To check with ohm meter,
measure the resistance across the
RTDs. The resistance . should be approximately 1100 ohm at
room temperature.
6
Replace the sensor, if necessary.
IMPORTANT : Use only a
209758 Series part # RTD
from Conair. This dryer
uses a 1000 ohm RTD, NOT
a 100 ohm RTD. Verify you
have the correct part.
