Only qualified personnel should conduct the tasks described in this section of the

The system can be used with any sc controller. Refer to the controller manual for
installation instructions.
The Contacting Conductivity sensor may be ordered with an internal or external digital

3.1 Connecting the Sensor to an sc Controller
3.1.1 Attaching a sc Sensor with a Quick-connect Fitting
The sensor cable is supplied with a keyed quick-connect fitting for easy attachment to the
controller (see
Figure 8: "Attaching the Sensor using the Quick-connect Fitting" ). 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.
Note: Use of a load termination box other than Cat. No. 5867000 may result in a hazard.
