medium. Use of natural gas as the
supply medium can result in personal
injury or property damage from fire or
explosion.
Supply pressure must be clean, dry, and oil-free air
or noncorrosive gas. Use of a 67CFR Filter
Regulator, or equivalent, to filter and regulate supply
air should suffice in most applications. The 67CFR
filter regulator can be integrally mounted with the
positioner. Use 3/8-inch tubing or 1/4-inch pipe for
the supply line.
CAUTION
To avoid equipment damage caused
by excessive pressure, do not exceed
the maximum pressure rating of the
actuator or positioner. Refer to the
appropriate instruction manual to
determine the maximum pressure
rating of the actuator, and to table 1
for the maximum pressure rating of the
positioner.
The supply pressure should be high enough to
permit setting the regulator 0.3 bar (5 psi) above the
upper limit of the appropriate pressure range, for
example: 1.4 bar (20 psig) for a 0.2 to 1.0 bar (3 to
15 psig) range. However, do not exceed the
maximum allowable supply pressure of 10.3 bar
(150 psig) nor the pressure rating of any connected
equipment.
Output Connections
For the 3610J or 3620J positioner, the OUTPUT A
connection must be plugged. Connect the OUTPUT
B connection to the actuator diaphragm casing

connection. Figure 8 shows a positioner with a
bypass valve. When the bypass valve is used,
connect the OUTPUT connection on the bypass
valve to the diaphragm casing connection on the
actuator. A manifold in the bypass body adapter
internally connects OUTPUT B to the bypass valve.
Use 3/8-inch tubing between the actuator and the
positioner.
For the 3610JP or 3620JP positioner, connect the
OUTPUT A connection to the lower actuator cylinder
connection and the OUTPUT B connection to the
upper actuator cylinder connection. Figure 1 shows
the positioner connected to a piston actuator. Use
3/8-inch tubing between the actuator and positioner.
For the 3611JP or 3621JP positioner, connect the
OUTPUT A connection to the lower actuator cylinder
connection and the OUTPUT B connection to the
upper actuator cylinder connection. Figure 2 shows
the positioner connected to a 585C actuator. Use
3/8-inch tubing between the actuator and the
positioner.
Instrument Connection
Use 3/8-inch tubing to connect the output from the
control device to the INSTRUMENT connection on a
pneumatic positioner. For the electro-pneumatic
positioner, refer to the Electrical Connections
section.
