BEFORE INSTALLATION
Review the power, input, and output specifications on page 7
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.
INSTALLATION
The controller must be mounted in a position that allows
clearance for wiring, servicing, removal, connection of the
LonWorks® Bus Jack, and access to the Neuron® Service Pin
(see Fig. 18 on page 19). The controller may be mounted in
any orientation.
IMPORTANT NOTE:
Avoid mounting in areas where acid fumes or other
deteriorating vapors can attack the metal parts of the
controller, or in areas where escaping gas or other explosive
vapors are present (see Fig. 6-Fig. 7 on page 11 for mounting
dimensions).
Mount Actuator onto Damper Shaft
(CVL4022AS-VAV1 only)
The CVL4022AS-VAV1 controller includes 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. 3).
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. 3).
IMPORTANT:
Determine the damper rotation and opening angle prior to
installation. See Fig. 4 and Fig. 5 for examples.
