Reassembling The 582I Converter - Emerson Fisher 3582i Instruction Manual

Instruction Manual
D200138X012
Note
To check the operation of the I/P module, remove the pipe plug (key 12), and connect a pressure gauge. Provide a 1.4 bar (20 psig)
supply pressure to the converter. With a 4 mA signal the pressure output should read 0.16 to 0.24 bar (2.3 to 3.5 psig). With a 20
mA input signal the pressure output should read 0.96 to 1.07 bar (14.0 to 15.5 psig).
1. Turn off the input signal to the converter. Release all supply pressure from the valve positioner.
2. Remove the housing cap (key 2).
3. Note the location of the wires, disconnect the field wiring from the terminal block. Disconnect the grounding wire
from the external ground screw
(key 10).
4. To remove the I/P module, remove the two screws (key 9), and pull the module out of the housing. Inspect the
O‐ring (key 6) and replace it, if necessary. Apply lubricant (key 15) to the O‐ring before replacing.
a. To remove the entire 582i converter from the 3582i valve positioner, continue with steps 5 through 7.
b. To replace the I/P module only, obtain a replacement I/P module listed in the parts list and refer to the
procedures for reassembling the 582i converter.
5. Disconnect the supply tubing, output tubing, and electrical conduit from the converter.
6. If necessary, remove the 67CFR regulator by removing the two screws (key 13). Then, remove the regulator from
the converter assembly. Inspect the O‐ring (key 3) and replace it if necessary. Apply lubricant (key 15) to the O‐ring
before replacing.
7. Remove the two screws (key 11) holding the 582i converter to the valve positioner case. Remove the converter
from the valve positioner case (key 1 in figure 21). Inspect the gasket (key 20) and replace it if necessary.

Reassembling the 582i Converter

During the following converter reassembly procedures, refer to figure 26 for key number locations.
1. If the 582i converter was removed from the valve positioner, install a new gasket (key 20) between the converter
housing and the valve positioner case. Attach the converter housing to the valve positioner case with the screws
(key 11) and tighten the screws.
2. If the I/P module was removed from the 582i converter, reinstall the I/P module in the converter housing. Secure
the I/P module with the two screws (key 9).
3. If other valve positioner components are removed, refer to the appropriate reassembly procedures and assemble
the valve positioner completely.
4. Reconnect the supply tubing, output tubing, and conduit to the valve positioner.
5. Reconnect the wiring to the terminal block. Do not overtighten the terminal screws. Maximum torque is 0.45 NSm
(4 lbfSin.). Reconnect the grounding wire to the housing ground screw (key 10) and replace the cap (key 2).
Note
To check the operation of the I/P module, remove the pipe plug (key 12), and connect a pressure gauge. Provide a 1.4 bar (20 psig)
supply pressure to the converter. With a 4 milliampere input signal the pressure output should read 0.16 to 0.24 bar (2.3 to 3.5
psig). With a 20 milliampere input signal the pressure output should read 0.96 to 1.07 bar (14.0 to 15.5 psig).
