Removing the
Electronics Board
The transmitter electronics are located behind the cover opposite the terminal
side.
NOTE
To prevent damage to the circuit board, remove power from the transmitter
before removing the electronics cover.
To remove the electronics board:
1.
Remove the housing cover opposite the field terminal side.
2.
Loosen the two captive screws that anchor the board.
NOTE
The circuit board is electrostatically sensitive. To prevent damage to the circuit
board, be sure to observe handling precautions for static-sensitive
components.
3.
Slowly pull the electronics board out of the housing. With the two
captive screws free of the transmitter housing, only the sensor
module ribbon cable holds the module to the housing.
4.
Disconnect the sensor module ribbon cable to release the electronics
board from the transmitter.
5.
Carefully tuck the cable connector completely inside the internal
shroud. The shroud protects the cable from damage that might occur
when the housing is rotated.
Removing the
Sensor Module
NOTE
Do not remove the housing until after you tuck the cable connector completely
inside of the internal shroud. The shroud protects the cable from damage that
can occur when you rotate the housing.
6.
Loosen the housing rotation set screw with a 5/64-inch hex wrench
and back off one full turn.
NOTE
Before removing the sensor module from the electrical housing, disconnect
the electronics board power cable from the sensor module. This will prevent
damage to the sensor module ribbon cable.
7.
Unscrew the housing from the module, making sure the shroud and
sensor cable do not catch on the housing. Damage can occur to the
cable if the internal shroud and sensor cable rotate with the housing.
Carefully pull the shroud and sensor ribbon cable assembly through
the housing opening.
NOTE
If the Coplanar flange has been removed, take care not to damage the
isolating diaphragm after disassembly. Damage to the isolating diaphragm
may lead to inaccurate measurements.
