VAV System
Description
The OE282 Damper Actuator is a shaft
mounted, floating point control actuator.
Actuators are 24VAC/24VDC with a 10K
ohm feedback signal for position monitor-
ing. Wiring connection to the actuator is by
means of a modular phone cable connector
located on the actuator cover. The actuator
is rated for 35 in-lb of torque. All actuators
are electronically protected against over-
load. The angle of rotation is mechanically
limited to 95
°
. When the end position of the
actuator or damper is reached, the actuator
automatically stops. For adjustment pur-
poses, the gears can be manually disen-
gaged by pushing the manual override
button on the actuator cover.
Applications
The OE282 Damper Actuator is used to
provide control of air volume dampers in
the WattMaster VAV systems. It is gener-
ally used in conjunction with an MG3204-
00-VABOX controller board.
Mounting
The Damper Actuator is designed to fit ei-
ther a 3/8” diameter or 1/2” diameter
damper shaft. The Damper Actuator slides
over the damper shaft through its integral
U-bolt clamp and is then tightened in place
using the 2 nuts provided on the U-bolt
clamp.
