Pull the wire through the wall and out of the junction box, leaving about six inches free.2. Pull the wire through the hole in the base plate.3. Secure the base to the box using the #6-32 x 1/2 inch mounting screw provided.4. Terminate the unit according to the guidelines in Termination on page 2.5. Attach Cover by latching it to the top of the base, rotating the cover down and snapping it into place.6. Secure the cover by backing out the lock-down screws using a 1/16" allen wrench until they are flush with the bottom ofthe cover.Drywall Mounting1. Place the base plate against the wall where you want to mount the sensor.2. Using a pencil, mark out the two mounting holes and the area where the wires will come through the wall.3. Drill two 3/16" holes in the center of each marked mounting hole. Insert a drywall anchor into each hole.Drywall Mounting continued on next page...*Some items may not be CE compliant, call Circon for additional information.Specifications subject to change without notice.CIRCON SYSTEMS CORPORATION • 110 - 6651 Fraserwood Place, Richmond, BC, Canada VJW 1J3 • website www.circon.comtoll free 1.800.338.1866 • telephone 604.232.4700 • technical support 1.877.350.2299 • facsimile 604.232.47471

CT/-RSOC or CT/-BSOCTermination and Troubleshooting16475_ins_circon_rsocTroubleshootingPossible Problems:General troubleshootingrev. 12/16/05Possible Solutions:- Determine that the input is set up correctly in the controller’s and building automationsoftware.- Check wiring for proper termination- Check for corrosion at either the controller or the sensor. Clean off the corrosion, re-stripthe interconnecting wire and reapply the connection. In extreme cases, replace thecontroller, interconnecting wire and/or sensor.- Label the terminals that the interconnecting wires are connected to at the sensor end andthe controller end. Disconnect the interconnecting wires from the controller and thesensor. With the interconnecting wires separated at both ends measure the resistancefrom wire-to-wire with a multimeter. The meter should read greater than 10 Meg-ohms,open or OL depending on the meter you have. Short the interconnecting wires together atone end. Go to the other end and measure the resistance from wire-to-wire with a multimeter.The meter should read less than 10 ohms (22 gauge or larger, 250 feet or less). Ifeither test fails, replace the wire.- Don’t forget to reconnect the wires.Temperature reading isincorrectSetpoint reading is incorrectOverride is not workingcorrectly- Determine that the temperature sensors wires are connected to the correct controller inputterminals and are not loose.- Check the wires at the sensor for proper connections.- Measure the physical temperature at the temperature sensor’s location using an accuratetemperature standard. Disconnect the temperature sensor wires and measure the temperaturesensor’s resistance across the sensor output pins with an ohmmeter. Comparethe temperature sensor’s resistance to the appropriate temperature sensor table below. Ifthe measured resistance is different from the temperature table by more than 5% callCircon technical support. Don’t forget to reconnect the wires.- Make sure the sensor leads are not touching one another or any other circuit components.- Make sure that the setpoint output is correct. Remove the setpoint output wire and checkthe output for the correct resistance output. See the setpoint range section of thisdocument for details. Don’t forget to reconnect the wire.-Check that the resistance across the temperature sensor output is less than 5 ohms whenthe override switch is pushedThermistor Output Table°F ° C 1K10K-3°F ° C 1K10K-31,000 ohms@32°F (0°C)10,000 ohms @77°F (25°C)1,000 ohms@32°F (0°C)10,000 ohms @77°F (25°C)50.010.0 103918,78677.0 25.0 109710,00055.012.8 105016,64978.0 25.6 10999,77860.015.6 106114,78380.0 26.7 11049,35362.016.7 106514,10382.0 27.8 11088,94864.017.8 106913,45984.0 28.9 11128,56266.018.9 107412,84786.0 30.0 11178,19668.020.0 107812,26888.0 31.1 11217,84770.021.1 108211,71790.0 32.2 11257,51672.022.2 108711,19595.0 35.0 11356,75474.023.3 109110,698100.0 37.8 11456,07976.024.4 109510,226104.0 40.0 1155.4 5,5944
