Installing A 1012T Mounting Track In Direct Mode - Siemens SITRANS FUS1020 Manual

Section 3
5. Once transducer is in place, secure with the transducer clamping screw. Do not overtighten.
Observe the upstream/downstream orientation and connect the transducer cable to the computer's
input jack. If a dual-channel unit, make sure you connect the cable to the input jacks of the correct
channel. Repeat this procedure for the number index transducer.

Installing a 1012T Mounting Track in Direct Mode

Paragraph 3.6 describes the Transducer Installation procedures that lead up to the automatic selec-
tion of transducers, mounting mode and spacing method. Shown is a Model 1012T mounting track to
accommodate size B3 Universal transducers. Examine the figure below which shows a typical Pick/
Install Xdcr menu screen. Note the automatic assignment of model numbers for the transducer and
mounting track (see below), plus the designation of number index.

1. Perform all required menu steps up until the point where the flow computer prompts you to press
<ENTER> to finish the transducer install routine. Note the reported number index.
You will be inserting an index pin into this hole and the reference hole. Check to ensure that you
have a matched set of transducers. They both should have the same S/N number but marked with
either an "A" or "B" (e.g., 100A and 100B).
2. The direct mount configuration uses two track rails, one for each transducer, installed 180
on the pipe. One track rail includes the tension screw while the other has a locating stud to support
the chain (see below and on next page).
