Page 9: Troubleshooting The Wiring
Troubleshooting the Wiring General The following tests are to be performed using standard testing practices and procedures and should only be carried out by properly trained and experienced persons. A good quality electrical test meter, capable of reading from at least 0 - 300 V (ac), 0 - 2,000,000 Ohms, and testing for continuity is essential to properly test the wiring and sensors. -
Page 10: Testing The Wiring
Testing the Wiring Testing 24 V (ac) Power Supply 1. Remove the front cover from the setpoint control. 2. Use an electrical test meter to measure (ac) voltage between the R and C terminals. The reading should be 24 V (ac) +/– 10%. 3. - Page 11 Testing the Sensor To test the sensor, the actual temperature at the sensor location must be measured. Use a good quality digital thermometer with a surface temperature probe for ease of use and accuracy. Where a digital thermometer is not available, place a spare sensor alongside the one to be tested and compare the readings.
