Defective sensor
• Be sure the sensor cable is properly
connected to both the sensor and the controller.
• Disconnect the cable from the controller and
check the resistance of the sensor and cable
combination. Compare to the chart at the end
of this section.
If the resistance is outside the allowable range,
disconnect the cable from the sensor and be
sure the resistance of the cable is above 1 mil-
lion ohms. Connect the ends of the cable wires
together and be sure the cable resistance is
less than 5 ohms. If either condition fails,
replace cable.
• Compare the resistance of the sensor itself
to the sensor resistance chart. Replace sensor
if necessary.
