Step 2 - Disassembly
1. Remove the outer ring by pulling up on the
three catches.
2. Remove the three screws.
3. Remove the blue sensor disk from the
sensor enclosure.
Avoid scratching any part of the surface of
the blue sensor disk. Scratches will result
in corrosion not covered by warranty.
Step 3 - Wiring
Remove the wiring terminal block by pulling up from the blue
sensor disk. Connect the 4 conductor wire to the yellow (YEL),
blue (BLU), red (RED) and black (BLK) wiring terminations. If
the installed 4 conductor cable uses a different color code, then
make a note of the wire color versus the wiring terminal color
names. Push the wiring terminal plug onto the pins of the blue
sensor disk. At the Snow Melting Control location, connect the
corresponding wires to the yellow, blue, red and black wire
terminations.

Step 4 - Assembly
1. Align the blue sensor disk tekmar logo with the highest point of the sensor enclosure
body. The blue sensor disk has a notch that ensures the sensor is installed in the
correct position.
2. Insert the three screws into the holes and screw them until tight. Do not over
tighten.
3. Align the three notches of the outer ring with the sensor body and push down until
each of the three corners have snapped on tight.
Maintenance
The sensor is installed in a harsh environment. Accumulation of dirt on the surface of the
sensor may affect snow detection. The sensor should be checked on a periodic basis
and, when necessary, cleaned.
1. Remove the outer ring by pulling up on the three catches.
2. A cloth with warm soapy water can be used to clean any dirt.
3. Rinse with water.
4. Align the three notches of the outer ring with the sensor body and push down until
each of the three corners have snapped on tight.

Testing and Troubleshooting
If the Snow Melt Control shows an error message describing a sensor failure, perform the
following test procedure:
The 4 conductor wires at the sensor should be disconnected.
•
Use a good quality electrical testing meter with an ohm scale range of 0 to 2,000,000
•
Ohms.
Using the ohmmeter and standard testing practices, measure the resistance between:
1. The yellow (YEL) and black (BLK) wiring terminals to measure a 10 kΩ sensor and use
the Temperature vs. Resistance Table to calculate the approximate temperature reading.
Measure the surface temperature of the 095 blue sensor disk and compare versus the
yellow to black temperature reading.
2. Measure the resistance between the blue (BLU) and black (BLK) wiring terminals. When
the sensor surface is clean and dry, the reading should be 2,000,000 Ohms. When the
sensor surface is wet it should be between 10,000 and 300,000 Ohms.
3. Measure the resistance between the red (RED) and black (BLK) wiring terminals This
reading should be between 45 to 47 Ohms.
If resistance readings are outside of the normal operating range, the sensor has failed.
