BEFORE INSTALLATION
The controller is available in eight models (see Table 1).
Review the power, input, and output specifications on page 2
before installing the controller.
— Hardware driven by Triac outputs must have a minimum
current draw, when energized, of 25 mA and a maximum
current draw of 500 mA.
— Hardware driven by the analog current outputs must have
a maximum resistance of 550 Ohms, resulting in a
maximum voltage of 11 volts when driven at 20 mA.
If resistance exceeds 550 Ohms, voltages up to 18 Vdc are
possible at the analog output terminal.
Electrical Shock Hazard.
Can cause severe injury, death or property
damage.
Disconnect power supply before beginning wiring or
making wiring connections to prevent electrical shock
or equipment damage.
INSTALLATION
For PVL0000AS, PVL4022AS, and PVL6436AS models, the
actuator is mounted first and then the controller is mounted.
For the other models, go to “Mount Controller” on page 4 to
begin the installation.
Mount Actuator onto Damper Shaft (PVL0000AS, PVL4022AS, and PVL6436AS)
PVL0000AS, PVL4022AS, and PVL6436AS controllers
include the direct-coupled actuator with Declutch mechanism,
which is shipped hard-wired to the controller.
The actuator mounts directly onto the VAV box damper shaft
and has up to 44 lb-in. (5 Nm) torque, 90-degree stroke, and
90 second timing at 60 Hz. The actuator is suitable for
mounting onto a 3/8 to 1/2 in. (10 to 13 mm) square or round
VAV box damper shaft. The minimum VAV box damper shaft
length is 1-9/16 in. (40 mm).
The two mechanical end-limit set screws control the amount
of rotation from 12° to 95°. These set screws must be securely
fastened in place. To ensure tight closing of the damper, the
shaft adapter has a total rotation stroke of 95° (see Fig. 1).
NOTE: The actuator is shipped with the mechanical end-limit
set screws set to 95 degrees of rotation. Adjust the
two set screws closer together to reduce the rotation
travel. Each “hash mark” indicator on the bracket
represents approximately 6.5° of rotation per side.
NOTE: The Declutch button, when pressed, allows you to
rotate the universal shaft adapter (see Fig. 1).
IMPORTANT
Determine the damper rotation and opening angle
prior to installation. See Fig. 2 and Fig. 3 on page 3
for examples.

Before Mounting Actuator onto Damper Shaft
(PVL0000AS, PVL4022AS, and PVL6436AS)
Tools required:
— Phillips #2 screwdriver - end-limit set screw adjustment
— 8 mm wrench - centering clamp
Before mounting the actuator onto the VAV box damper shaft,
determine the following:
1. Determine the damper shaft diameter. It must be
between 3/8 in. to 1/2 in. (10 to 13 mm).
2. Determine the length of the damper shaft. If the length
of the VAV box damper shaft is less than 1-9/16 in.
(40 mm), the actuator cannot be used.
3. Determine the direction the damper shaft rotates to
open the damper (CW or CCW) (see Fig. 3). Typically,
there is an etched line on the end of the damper shaft
that indicates the position of the damper. In Fig. 2, the
indicator shows the damper open in a CW direction.
4. Determine the damper full opening angle (45, 60, or 90
degrees). In Fig. 2, the damper is open to its full open
position of 90 degrees.
Fig. 3. Determining the rotation direction (CW or CCW)
for damper opening.
Mounting Actuator onto Damper Shaft (PVL0000AS,
PVL4022AS, and PVL6436AS )
The unit is shipped with the actuator set to rotate open in the
clockwise (CW) direction to a full 95 degrees. The extra 5
degrees ensures a full opening range for a 90 degree damper.
The installation procedure varies depending on the damper
opening direction and angle:
1. If the damper rotates clockwise (CW) to open, and the
angle of the damper open-to-closed is 90 degrees:
a. Manually open the damper fully (rotate clockwise).
b. Using the Declutch button, rotate the universal shaft
adapter fully clockwise.
c. Mount the actuator to the VAV damper box and shaft.
d. Tighten the two bolts on the centering clamp
(8 mm wrench; 70.8–88.5 lb-in. [8–10 Nm] torque).
When the actuator closes, the damper rotates CCW
90 degrees to fully close.
2. If the damper rotates clockwise (CW) to open, and the
angle of the damper open-to-closed is 45 or 60 degrees:
a. Manually open the damper fully (rotate clockwise).
b. The actuator is shipped with the mechanical
end-limits set at 95 degrees. Adjust the two
mechanical end-limit set screws to provide the
desired amount of rotation. Adjust the two set
screws closer together to reduce the rotation travel.
c. Tighten the two mechanical end-limit screws
(Phillips #2 screwdriver; (26.5–31 lb-in. [3.0–3.5
Nm] torque).
d. Using the Declutch button, rotate the universal shaft
adapter fully clockwise.
e. Mount the actuator to the VAV damper box and shaft.
f. Tighten the two bolts on the centering clamp
(8 mm wrench; 70.8–88.5 lb-in. [8–10 Nm] torque).
g. When the actuator closes, the damper rotates CCW
either 45 or 60 degrees to fully close.
3.
If the damper rotates counterclockwise (CCW) to open,
and the angle of the damper open-to-closed is 90 degrees:
a. Manually open the damper fully (rotate counter-
clockwise).
b. Using the Declutch button, rotate the universal shaft
adapter fully counterclockwise.
c. Mount the actuator to the damper box and shaft.
d. Tighten the two bolts on the centering clamp (8 mm
wrench; 70.8–88.5 lb-in. [8–10 Nm] torque). When
the actuator closes, the damper rotates CW
90 degrees to fully close.
4. If the damper rotates counterclockwise (CCW) to open,
and the angle of the damper open-to-closed is 45 or
60 degrees:
a. Manually open the damper fully (rotate counter-
clockwise).
b. The actuator is shipped with the mechanical
end-limits set at 95 degrees. Adjust the two
mechanical end-limit set screws to provide the
desired amount of rotation. Adjust the two set
screws closer together to reduce the rotation travel.
c. Tighten the two mechanical end-limit screws
(Phillips #2 screwdriver; (26.5–31 lb-in. [3.0–3.5
Nm] torque).
d. Using the Declutch button, rotate the universal shaft
adapter fully counter-clockwise.
e. Mount the actuator to the VAV damper box and shaft.
f. Tighten the two bolts on the centering clamp
(8 mm wrench; 70.8–88.5 lb-in. [8–10 Nm] torque).
g. When the actuator closes, the damper rotates CW
either 45 or 60 degrees to fully close.

Panel Mounting
The controller enclosure is constructed of a plastic base plate
and a plastic factory-snap-on cover.
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 controller onto the top of the DIN rail.
2. Push down and in to snap the two bottom flex connectors of the controller onto the DIN rail.
NOTES:
— 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.
Connect the high pressure or upstream tube to the plastic
restrictor port labeled (
downstream tube to the restrictor port labeled (
+), and the low pressure or
-). See labeling
in Fig. 9. When twin tubing is used from the pickup, split the
pickup tubing a short length to accommodate the connections.
NOTES:
— 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
+) connected to the air
flow pickup.
— The tubing from the air flow pickup to the control-
ler 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 con-
nector. Always pull straight away from the connector or use diagonal cutters to cut the edge of
the tubing attached to the connector. Never
remove by pulling at an angle.

NOTES:
— For multiple controllers operating from a single
transformer, the same side of the transformer secondary must be connected to the same power
input terminal in each controller. Controller configurations will not necessarily be limited to three
devices, but the total power draw, including
accessories, cannot exceed 100 VA when powered by the same transformer (U.S. only). For
power and wiring recommendations, see “Wiring”
on page 5 The earth ground terminal (terminal 3)
must be connected to a verified earth ground for
each controller in the group (see Fig. 12 on
page 7).
— All loads on the controller must be powered by the
same transformer that powers the controller itself.
A controller can use separate transformers for
controller power and output power.
— Keep the earth ground connection (terminal 3)
wire run as short as possible.
— Do not connect the universal input COM
terminals, analog output COM terminals or the
digital input/output COM terminals to earth
ground. Refer to Fig. 10–Fig. 12 for wiring
examples.
The 24 Vac power from an energy limited Class II power
source must be provided to the controller. To conform to Class
II restrictions (U.S. only), the transformer must not be larger
than 100 VA.
— Maintain at least a 3 in. (7.6 cm) separation
between Triac outputs and L
ONWORKS® wiring
throughout the installation.

NOTE: When attaching two or more wires to the same termi-
nal, other than 14 AWG (2.0 sq mm), be sure to twist
them together. Deviation from this rule can result in
improper electrical contact (see Fig. 13).
Each terminal can accommodate the following gauges of wire:
— Single wire: from 22 AWG to 14 AWG solid or stranded
— Multiple wires: up to two 18 AWG stranded, with 1/4 watt
wire-wound resistor
Prepare wiring for the terminal blocks, as follows:
1. Strip 1/2 in. (13 mm) insulation from the conductor.
2. Cut a single wire to 3/16 in. (5 mm). Insert the wire in
the required terminal location and tighten the screw.
3. If two or more wires are being inserted into one terminal
location, twist the wires together a minimum of three
turns before inserting them (see Fig. 13).
4. Cut the twisted end of the wires to 3/16 in. (5 mm)
before inserting them into the terminal and tightening
the screw.
5. Pull on each wire in all terminals to check for good
mechanical connection.
3. CUT TWISTED END OF WIRES TO 3/16 IN. (5 MM)
BEFORE INSERTING INTO TERMINAL AND
TIGHTENING SCREW. THEN PULL ON EACH
WIRE IN ALL TERMINALS TO CHECK FOR
GOOD MECHANICAL CONNECTION.
