1. Loosen the two screws (key 19C).
2. Tighten the pivot pin (key 19L) by compressing
the upturned ears of the arm support (key 19K).
Tighten the screws (key 19C) and make sure the
flapper (key 19B) does not rub on the supports.
3. The flapper should be snug, but not constricting
to pivot action.
Replacing the 582i Converter Primary
O-Ring and Filter
Key numbers used in this procedure are shown in
figure 26.
1. Locate and remove the nozzle restriction adaptor
assembly (key 4).
2. Inspect and replace, if necessary, the O-rings
(keys 5 and 6). Apply lubricant (key 15) to the O-ring
before replacing.
3. Inspect and replace the filter cartridge (key 23).
Replacing the 582i Converter Housing
Cap O-Ring
Key numbers used in this procedure are shown in
figure 26.
1. Unscrew and remove the converter housing cap
(key 2). Inspect and replace the O-ring (key 8), if
necessary. Apply lubricant (key 15) to the O-ring
before replacing.

Removing the 582i Converter

During the following converter removal procedures,
refer to figure 26 for key number locations.
CAUTION
The I/P module should never be
disassembled because the magnetism
in the coils will decrease permanently.
If troubleshooting or alignment
attempts indicate a faulty I/P module,
replace the module or return the
converter to your Emerson Process
Management sales office for repair.
3582, 582i, and 3583
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 20). 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
