*Notes:

1.Use the voltage column to compare the meter voltage with the sensor connected to the controller and with the controller pow- ered.

2.Read voltage with meter set on DC volts. Place the “-”(minus) lead on GND terminal and the “+”(plus) lead on the sensor input terminal being investigated.

3.If the voltage is less than 0.05 VDC, then the sensor or wiring is “shorted” or “open”
