582i Converter Installation
Note
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.
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.
Note
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.
Note
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.
