3.4 Connecting/Wiring the Sensor Cable
The sensor cable is supplied with a keyed quick-connect fitting for easy
attachment to
the controller, see Figure 3-19. Retain the connector cap to seal the
connector opening in case the sensor must be removed. Optional extension
cables may be purchased to extend the sensor cable length. If the total cable
length exceeds 100 M (300 ft), a termination box must be installed. See the
Replacement Parts section in the sensor manual for part number information.
Figure 3-19 Attaching the Sensor using the Quick-connect Fitting
Modify the controller for sensor hard-wiring as follows:
1. Open the controller cover.
2. Disconnect and remove the existing wires between the quick connect and
terminal block J5, see
Figure 3-20 on page 18.
3. Remove the quick connect fitting and wires and install the threaded plug on
the opening to maintain the environmental rating.
