Detailed Sanitary Mount Installation Instructions
1.
Wiring:
a.
Thread the retaining collar over the cable and onto the sensor with the threads facing the front
of the sensor.
b.
Route the cable either through conduit or on a cable tray.
c.
Insert the sensor cable into the Model C99 controller through a watertight cord grip. Conduit
holes are provided for the cord grip on the bottom of the C99 controller.
d.
Connect the sensor wires into the C99 sensor terminal block as shown in the C99 manual.
2.
Calibrate:
a.
Power the C99 controller.
b.
Remove the protective cap from the sensor head.
c.
Calibrate the Conductivity sensor as explained in the C99 manual. Subsequent calibrations
should be scheduled based on process demands.
d.
If measurement response time is slow or if the sensor will not calibrate, refer to Section 4 for
maintenance, refurbishment and troubleshooting suggestions.
3.
Mount:
a.
Insert the sensor into the adapter making sure the front o-ring on the sensor is seated.
b.
Thread the retaining collar into the adapter and tighten with a wrench until the face of the
sensor head is flush with the adapter and the o-ring forms a seal.
c.
Place a sanitary gasket on the branch flange.
d.
Insert the sensor with the adapter into the branch of the tee; be sure the pipe remains full while
installing to minimize trapped air.
e.
Install and tighten the sanitary clamp to retain the sensor and adapter in the tee.
Route the interconnect cable through metal conduit to minimize electrical noise
that may interfere with the sensor signal.
Do not route the interconnect cable conduit where there are AC or DC power
cables which create electrical noise that may interfere with the sensor signal.
