Reference figure 4 for wiring diagram. Also note the jumper that is required on the remote sensor connector board.
Failure to install this jumper will cause a sensor fault condition.
Remote Mounting Configuration - Bridge Voltage Adjustment
When a sensor is remote mounted, consideration must be given to the lengths of cable used and how it affects the
sensor bridge voltage. Differing lengths of cables will have varying amounts of resistance which will shift the sensor
bridge voltage. Because of this, the bridge voltage will need to be adjusted after initial power up. This adjustment is
only required after initial installation and will not be necessary thereafter, even in the event of replacement of the
plug-in sensor. See section 3.6.2 for instructions.
3.6 START UP
Upon completion of all mechanical mounting and termination of all field wiring, apply system power and observe
the following normal conditions:
