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.

Disconnect power supply before beginning wiring or 

making wiring connections to prevent electrical shock 

or equipment damage.

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.

The controller may be mounted in any orientation.

explosive vapors are present. See Fig. 4–Fig. 7 on 

page 4 for mounting dimensions.

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.

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).
