conduit according to local and national electrical
codes which apply to the application.
Refer to figures 9, 10 and 11 when connecting field
wiring from the control device to the converter.
Connect the positive wire from the control device to
the converter positive (+) terminal, and the negative
wire from the control device to the converter
negative (−) terminal. Do not overtighten the terminal
screws. Maximum torque is 0.45 NSm (4 lbfSin.).
Connect the converter grounding terminal to an
earth ground.
582i Converter Installation
Contact your Emerson Process
Management sales office for
application information before
upgrading an existing 3582 valve
positioner by field installation of a 582i
electro-pneumatic converter.
WARNING
Avoid personal injury from sudden
release of process pressure. Before
mounting the 582i converter:
D Always wear protective clothing,
gloves, and eyewear when performing
any maintenance operations.
D Do not remove the actuator from
the valve while the valve is still
pressurized.
D Disconnect any operating lines
providing air pressure or a control
signal to the actuator. Be sure the
actuator cannot suddenly open or
close the valve.
D Use bypass valves or completely
shut off the process to isolate the
valve from process pressure. Relieve
process pressure on both sides of the
valve.
D Vent actuator loading pressure.
D Use lock-out procedures to be
sure that the above measures stay in
effect while you work on the
equipment.
Note
3582, 582i, and 3583
D Do not open when an explosive
dust atmosphere is present.
D Check with your process or safety
engineer for any additional measures
that must be taken to protect against
process media.
Before planning to retrofit an installed
3582 positioner, refer to the positioner
mounting plate illustrations shown in
figure 5. Mounting plates with a
three-hole mounting pattern
(positioner to mounting plate) cannot
support a 582i converter. Do not
attempt to mount a 582i converter on
an existing 3582 positioner which has
a three-hole mounting pattern.
Isolate the control valve from the line pressure, and
release pressure from both sides of the valve body.
Use lock-out procedures to be sure that the above
measures stay in effect while you work on the
equipment.
If a 3582 pneumatic valve positioner has previously
been installed using a mounting plate with a
five-hole mounting pattern (positioner to mounting
plate), either at the factory or in the field, it can be
upgraded to a 3582i electro-pneumatic valve
positioner by installation of a 582i converter. To
install a 582i converter, refer to the following
instructions.
Inspect the existing valve positioner to
determine the input signal range. If the
input signal range is not 0.2 to 1.0 bar
(3 to 15 psig), refer to the appropriate
sections of this manual describing
input signal ranges and how to change
the range spring.
1. Inspect the positioner mounting plate. Be certain
that five screws fasten the positioner to the mounting
plate. Two additional screws fasten the plate to the
actuator.
When the positioner is correctly attached to the
mounting plate, proceed with the installation by
taking the control valve/actuator/positioner package
out of service.
2. Properly vent the actuator loading pressure and
the supply pressure. Disconnect the pressure tubing
connections to the valve positioner.
