6. BATTERY TEMPERATURE SENSOR
WARNING: IT IS IMPORTANT TO MOUNT THE TEMPERATURE SENSOR ON THE BATTERIES
FOR PROPER TEMPERATURE COMPENSATION. IF THIS CANNOT BE DONE, LOCATE THE SENSOR
AS LOW AS POSSIBLE IN THE BUNGALOW, ENCLOSURE, OR CABINET.
The external battery temperature sensor is an optional way of extending battery life by using temperature
compensation. One end of the temperature sensor cable has a three-pin plug that plugs into a receptacle
labeled “BATTERY TEMP SE NSOR” on the UIM (see Figure 7-1). The other end of the cable has the
temperature sensor sealed in a terminal.
The terminal-type sensor should be attached to a negative (-) battery post near the center of the battery pack.
If the threaded stud is long enough above the battery jumper nut, attach the sensor with another nut. Torque
this nut to proper specifications. If the stud is too short, the nut holding the jumper wire will need to be
removed. Open or remove the load and charging circuits to the batteries. Remove the nut holding the jumper
and add the sensor, then torque the nut to the proper specifications. Then close or connect the load and
charging circuits back to the batteries.
Securely fasten the temperature sensor cable to protect the sensor from being torn from the battery.
Secure the sensor cable to a fixed object to ensure the sensor will not be pulled loose. Use a cable tie mount
on the battery or on the adjacent battery, if necessary.
