Installing the Tank Wall Plate Assembly
The figure below illustrates the Tank Wall Plate (TWP) assembly components.
Tank Wall Plate Assembly Components
Caution:
The use of implements other than those mentioned in these instructions can damage the
feed-through body.
This assembly provides a pressurized/vacuum seal for the transformer and optically connects the internal fiber
optic probe to the external fiber optic extension cables. The tank wall penetrators are welded onto the tank wall
feed-through plate.
After the transformer is assembled in the tank, run the internal probes to the tank wall penetrators.
To assemble the probe at the TWP (inside the transformer):
1.
Insert the probe-side SMA-type connector with the lock nut into the TWP (feed-through). Ensure the
Viton O-ring, located on the body of the probe-side SMA-type connector, is not damaged.
2.
Firmly tighten the jam nut by hand or with small hand pliers, to the point of resistance. Do not over
tighten.
3.
Tighten the lock nut against the TWP assembly. Using a torque wrench, tighten one-half turn past hand-
tight. Apply less than 25 foot pounds of torque.
4.
Check the probe signal level with the LumaSMART controller to ensure the probe is properly installed.
Signal level should be between 60% and 95%. (Refer to Section 4.5
Testing the Probe Signal Strength.)
5.
Complete the LumaSMART installation using the appropriate information provided in Chapter 4
