Wiring Connections
1. Loosen the screw on the conduit fitting and lift up
to remove the fitting.
2. Using a utility knife or drill, cut the red plug
to accept wiring or replace the plug with an
application-specific fitting.
NOTE: The red plug (or similar fitting) protects
internal components from debris, helping to
ensure long actuator life.
3. Thread wires through the plugged opening and
connect to the terminal block as shown.
4. Make the air pressure connections (see
Pressure Connection on page
MAX flow (see Min. and Max. Flow Limits on
page 3), and change the rotation direction (see
Rotation Direction on page
5. Reinstall the conduit fitting and tighten the screw.

Rotation Direction
The CSP-4702 is factory-set for counterclockwise to
close. To reverse the direction (with the conduit cover
removed), move the
jumper to the CW position.

Air Pressure Connection
Connect the CSP-4702 to a differential pressure flow
sensor with 1/4-inch OD x 0.040-inch wall FR instru-
ment and control tubing:
1. Connect the "HI" port to the
(high side) "H" of the sensor.
2. Connect the "LO" port to the
(low side) "L" of the sensor.
NOTE: For use as a static pressure controller, see
the
Control Application
NOTE: For VAV applications, the SSS-1000 series
differential pressure flow sensor must be
mounted with the arrow pointing in the
direction of the air flow. To connect to 1/4-
inch tubing from the CSP-4702, an SSS-100x
differential pressure flow sensor requires
a 3/8" to 1/4" barb union adapter and 1"
of 3/8" OD x 0.062 "FR" tubing for both
connections (as shown in the illustration).
An SSS-101x sensor does not require the
3/8" tubing or adapter.
NOTE: All tubing should be free of kinks and
restrictions.

NOTE: For about 15 seconds after power is applied,
no rotation occurs and one or both of the
LEDs will flash. The Close LED illuminates
(solid red) when the actuator is closing. The
Open LED illuminates (solid green) when
opening. When the actuator reaches the end
of rotation or the mechanical stop, the LED
may stay illuminated a brief time if the
called for condition remains unsatisfied.
