8. With a pencil or chalk mark a generous area around the perimeter of the track assembly.
Loosen and move the assembly away from marked area.
9. Prepare the area you marked by degreasing the surface, if needed, and removing any
grit, corrosion, rust, loose paint or surface irregularities with the abrasive pipe
conditioning material provided. Clean the pipe of all debris and abrasive particles.
10.Rotate the track into the position that was just cleaned. Insert the index pin into the REF
hole.
11.Insert the index pin into the reference hole.
12.Select a sensor and apply a thin band of couplant compound to the sensor’s emitting
surface.
13.Place the sensor between the track rails, slightly behind the pin and under the clamping
screw assembly. Slide it forward until it butts up firmly against the reference pin.
14.Once the sensor is in place secure it with the sensor clamping screw. Do not over tighten.
15.Repeat the procedure for the number index sensor making sure to insert an index pin into
the correct number index hole. Refer to the mounting track (side view) figure above.
16.Fill connector end with Super Lube prior to connecting.
17.Apply Super Lube to the internal threads at the large end of the thread connector.
18.Observing the upstream and downstream orientation, attach the 1A (upstream) and 1B
(downstream) cables to the sensors and make snug. Attach other ends of cables to the
transmitter at 1A and 1B terminals of the transmitter.
Installing a mounting track in Direct mode
The sensor installation procedures show how the automatic selection of sensors, mounting
mode and spacing method are established. Note the automatic assignment of model
numbers for the sensor and mounting track, plus the designation of the number index.
The combination of two mounting tracks and a spacer guide is the recommended way to
mount sensors in the Direct mode. This method ensures that sensors will align exactly 180°
from each other and remain spaced the proper distance apart.
