W.E.E.E. DIRECTIVE
At the end of their useful life the packaging and product should be disposed of via a suitable recycling
centre. Do not dispose of with household waste. Do not burn.
TROUBLESHOOTING
PROBLEM
Sensor reading is incorrect
Sensor reads infinity/very high resistance
Sensor reads low resistance
Erratic readings
SOLUTION(S)
•
Verify sensor wiring to controller is not damaged and has continuity.
•
Verify sensor or wires are not shorted together.
•
Verify controller is setup for correct sensor curve.
•
Disconnect wires from sensor terminal block, tighten terminal block
screws down, and take a resistance (ohm) reading with a multimeter.
•
Compare the resistance reading to the Temperature Vs Resistance
Curves online:

•
Verify proper mounting location to confirm no external factors are
affecting reading.
•
Sensor or wires are open.
•
Sensor or wires are shorted together.
•
Condensation on PCB board
•
Bad wire connections.

WIRING INSTRUCTIONS
(Continued)
Connect thermistor/RTD wire leads to controller analog input wires using wire nuts, terminal blocks, or
crimp style connectors. All wiring must comply with all local and National Electric Codes. After wiring,
attach the cover to the enclosure.
Note:
When using a shielded cable, be sure to connect only (1) end of the shield to ground at the
controller. Connecting both ends of the shield to ground may cause a ground loop. When
removing the shield from the sensor end, make sure to properly trim the shield to prevent any
chance of shorting.
Note:
If the controller requires a (2) wire input for a RTD, connect the (2) common wires (same
color) together. If the controller requires (3) wires, use (3) individual wires.
