Installation
3.5.1.2 Using the Optional pH (9184sc TFC only)
The optional pH ( Figure 2 on page 7 ) is used when analysis is needed for measuring all of
the free available chlorine (both HOCI and OCI – ). See 4.3 Sensor Setup on page 19 for
selecting this option using the controller during initial sensor parameter selection.
1. Remove the red cap from the left side of the flow cell.
2. Remove the O-ring from the white blank.
3. Gently remove the cover from the pH probe.
4. Put the O-ring from Step 2 onto the pH probe, sliding it gently over the glass end and
up the probe until it is flush against the red connection.
5. Insert the newly assembled probe into the left chamber of the flow cell.
6. Attach the keyed electrode cable.
3.6 Connecting the Sensor with the sc Controller
3.6.1 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 (
Figure 9 ). 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.
