NOTE: The controller is designed so that the cover does not
need to be removed from the base plate for either
mounting or wiring.
The controller mounts using four screws inserted through the
corners of the base plate. Fasten securely with four No. 6 or
No. 8 machine or sheet metal screws.
The controller can be mounted in any orientation. Ventilation
openings are designed into the cover to allow proper heat
dissipation, regardless of the mounting orientation.
DIN Rail Mounting (PUL1012S, PUL4024S,
PUL6438S, PVL4024NS, and PVL6438NS)
To mount the PUL1012S, PUL4024S, PUL6438S,
PVL4024NS, or PVL6438NS controller on a DIN rail [standard
EN50022; 1-3/8 in. x 9/32 in. (7.5 mm x 35 mm)], refer to Fig. 8
and perform the following steps:
1. Holding the controller with its top tilted in towards the
DIN rail, hook the two top tabs on the back of the control-
ler onto the top of the DIN rail.
2. Push down and in to snap the two bottom flex connec-
tors of the controller onto the DIN rail.
IMPORTANT
To remove the controller from the DIN rail, perform
the following:
1. Push straight up from the bottom to release the top
tabs.
2. Rotate the top of the controller out towards you and
pull the controller down and away from the DIN rail to
release the bottom flex connectors.

Air flow Pickup
For PVL0000AS, PVL4022AS, PVL4024NS, PVL6436AS, and

ports on the controller (see Fig. 9).

Before wiring the controller, determine the input and output
device requirements for each controller used in the system.
Select input and output devices compatible with the controller
and the application. Consider the operating range, wiring
requirements, and the environment conditions when selecting
input/output devices. When selecting actuators for modulating
applications consider using floating control. In direct digital
control applications, floating actuators will generally provide
control action equal to or better than an analog input actuator
for lower cost.
Determine the location of controllers, sensors, actuators and
other input/output devices and create wiring diagrams. Refer to
Fig. 19 to Fig. 25 beginning on page 16 for illustrations of
typical controller wiring for various configurations.

Use 1/4 inch (6 mm) outside diameter, with a 0.040
in. (1 mm) wall thickness, plenum-rated 1219 FR
(94V-2) tubing.
Always use a fresh cut on the end of the tubing
that connects to the air flow pickups and the
restrictor ports on the controller.

If controllers are mounted in unusually dusty or dirty
environments, an inline, 5-micron disposable air
filter (use 5-micron filters compatible with
pneumatic controls) is recommended for the high
+
pressure line (marked as
flow pickup.
The tubing from the air flow pickup to the controller
should not exceed three feet (0.914 m). Any length
greater than this will degrade the flow sensing
accuracy.
Use caution when removing tubing from a connec-
tor. Always pull straight away from the connector
or use diagonal cutters to cut the edge of the tub-
ing attached to the connector. Never remove by
pulling at an angle.
