6.5.2
Installing terminal block
1.
Gently slide the terminal block into place, making sure the two power posts from the
electronics housing properly engage the receptacles on the terminal block.
2.
Tighten the captive screws.
3.
Replace the electronics housing cover. The transmitter covers must be fully engaged to
meet Explosion-Proof requirements.
6.5.3
Reassembling the Rosemount 2051C process flange
1.
Inspect the sensor module PTFE o-rings. Undamaged o-rings may be reused. Replace
o-rings that show any signs of damage, such as nicks, cuts, or general wear.
Note
If you are replacing the o-rings, be careful not to scratch the o-ring grooves or the surface of the
isolating diaphragm when removing the damaged o-rings.
2.
Install the process connection. Possible options include:
a.
Coplanar Process Flange:
–
Hold the process flange in place by installing the two alignment screws to
finger tightness (screws are not pressure retaining). Do not overtighten as this
will affect module-to-flange alignment.
–
Install the four 1.75-in. flange bolts by finger tightening them to the flange.
b. Coplanar Process Flange with Flange Adapters:
–
Hold the process flange in place by installing the two alignment screws to
finger tightness (screws are not pressure retaining). Do not overtighten as this
will affect module-to-flange alignment.
–
Hold the flange adapters and adapter o-rings in place while installing (in the
desired of the four possible process connection spacing configurations) using
four 2.88-inch bolts to mount securely to the coplanar flange. For gage
pressure configurations, use two 2.88-inch bolts and two 1.75-inch bolts
c.
Manifold:
–
Contact the manifold manufacturer for the appropriate bolts and procedures.
3.
Tighten the bolts to the initial torque value using a crossed pattern. See
for appropriate torque values.
4.
Using same cross pattern, tighten bolts to final torque values seen in
.
See
for complete warning
