When mounting the instrument the correct orientation of the flow element must be maintained to ensure repeatability to within specifications.
Apply sealant to the male threads.
Carefully place in the process media line with the machined flat facing up.
Tighten the process connection. To avoid leaks do not overtighten or
Shown below is the 1 inch NPT mounting.
Step 3. Wiring Preparation
Before the instrument is opened to install the wiring, FCI recommends that the following ESD precautions be observed: Use a wrist band or heel strap with a
1 megohm resistor connected to ground. If the instrument is in a shop setting there should be static conductive mats on the work table and floor with a 1 megohm resistor connected to ground. Connect the instrument to ground. Apply antistatic agents such as Static Free made by Chemtronics (or equivalent) to hand tools to be used on the instrument. Keep high static producing items away from the instrument such as
The above precautions are minimum requirements to be used. The complete use of ESD precautions can be found in the U.S. Department of Defense Handbook 263.
Open the instrument enclosure to wire the instrument. Remove the control circuit by lifting and rocking the circuit board back and forth to expose the terminal block as shown. The wiring connections are then accessible.
