Orion Control Systems OE742-32-VAVZ User Manual

Temperature Sensor Testing
Temperature Sensor Testing
The following sensor voltage and resistance table is provided to aid in
checking sensors that appear to be operating incorrectly. Many system
operating problems can be traced to incorrect sensor wiring. Be sure all
sensors are wired per the wiring diagrams in this manual.
If the sensors still do not appear to be operating or reading correctly,
check voltage and/or resistance to conrm that the sensor is operating
correctly per the table. Please follow the notes and instructions in Figure
20 when checking sensors.
