Reassembly procedures
1.
Inspect all cover and housing (non-process wetted) O-rings and replace if necessary.
Lightly grease with silicone lubricant to ensure a good seal.
2.
Carefully tuck the cable connector completely inside the internal black cap. To do so,
turn the black cap and cable counterclockwise one rotation to tighten the cable.
3.
Lower the electronics housing onto the module. Guide the internal black cap and cable
on the sensor module through the housing and into the external black cap.
4.
Turn the module clockwise into the housing.
Important
Make sure the sensor ribbon cable and internal black cap remain completely free of the housing
as you rotate it. Damage can occur to the cable if the internal black cap and ribbon cable
become hung up and rotate with the housing.
5.
Thread the housing completely onto the sensor module. The housing must be no more
than one full turn from flush with the sensor module to comply with explosion proof
requirements.
6.
Tighten the housing rotation set screw using a
5
/
64
-inch hex wrench.
6.5.1
Attaching electronics board
1.
Remove the cable connector from its position inside of the internal black cap and attach
it to the electronics board.
2.
Using the two captive screws as handles, insert the electronics board into the housing.
Make sure the power posts from the electronics housing properly engage the
receptacles on the electronics board. Do not force. The electronics board should slide
gently on the connections.
3.
Tighten the captive mounting screws.
4.
Replace the electronics housing cover. The transmitter covers must be engaged
metal-to-metal to ensure a proper seal and to meet Explosion-Proof requirements.
6.5.2
Reassembling the 3051C 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.
