Introduction
Scope of Manual
This instruction manual includes installation,
operation, calibration, maintenance, and parts
ordering information for 3610J and 3620J Series
positioners. (i.e. 3610J, 3610JP, 3611JP,
W6594 / IL
Figure 2. 3621JP Positioner with 585C Actuator
3620J, 3620JP, and 3621JP). This manual also
provides field installation information for the 3622
electro-pneumatic converter. Refer to separate
instruction manuals for information on the actuator
and control valve. Contact your Emerson Process
Managementtsales office if assistance is needed
in obtaining actuator or control valve instruction
manuals.
Do not install, operate or maintain a 3610J or 3620J
Series positioner without first Dbeing fully trained
and qualified in valve, actuator and accessory
installation, operation and maintenance, and D
carefully reading and understanding the contents of
this manual. If you have any questions about these
instructions, contact your Emerson Process
Management sales office.
Description
3610J or 3610JP pneumatic positioners and 3620J
or 3620JP electro-pneumatic positioners are used
with diaphragm rotary actuators and piston rotary
actuators as shown in figure 1. 3611JP and 3621JP
positioners are used with 585, 585R, 585C, or
585CR sliding stem actuators as shown in figure 2.
The positioner mounts integrally to the actuator
housing and provides a valve ball, disk, or plug
position for a specific input signal. The positioner
accepts either a pneumatic or milliampere input
signal. Refer to the Type Number Description for a
detailed explanation of type numbers.
