The sensor cable is supplied with a keyed quick-connect fitting for easy
attachment to the controller, see Figure 20. Retain the connector cap to seal the
connector opening in case the sensor must be removed.
The 1720E sensor cable may be extended by a maximum of 7.62 m (25 ft),
see Replacement Parts and Accessories on page 55.
Modify the controller for sensor hard-wiring as follows:
1. Remove all power to the controller.
2. Open the controller cover.
