INSTALLATION

Before mounting the controller on damper shaft,
review the power, inputs and output specification
on pg.3.
Hardware driven by the analog current outputs
must have a maximum resistance of 550 Ω.
IMPORTANT
Avoid mounting in areas where acid fumes
or other deteriorating vapors can harm the
metal parts of the controller, or in areas
where escaping gas or other explosive
vapors are present.

Before Mounting Actuator onto the Damper
Shaft
WEB-VA423B24N controller includes the direct-
coupled actuator with Declutch mechanism, which
is shipped hard-wired to the controller.
Before mounting the WEB-VA423B24N onto the
VAV damper shaft, do the following:
1. Ensure that the diameter of the damper shaft
is within the allowed limits:
Square shaft
Round shaft
2. Ensure that the damper shaft has a length of

3. Determine the direction in which the damper
shaft rotates to open the damper (CW or CCW)
(see Fig. 5). Typically, there is an etched line
on the end of the damper shaft that indicates
the position of the damper. In Fig. 6, the
indicator shows the damper open in a CW
direction.

IMPORTANT
Mount the actuator flush with damper
housing or add a spacer between the actuator
mounting surface and damper box housing.
4. Determine the damper full opening angle
(45, 60, or 90 degrees). In Fig. 6, the
damper is open to its fully open position of
90 degrees.
