Application
For on-off and floating point control of dampers in HVAC
systems. Actuator sizing should be done in accordance with
the damper manufacturer’s specifications.
The actuator is mounted directly to a damper shaft from 1/4”
up to 5/8” in diameter by means of its standard universal
clamp. Shafts up to 3/4” diameter can be accommodated by
an accessory clamp.
Operation
The actuator is not provided with and does not require any
limit switches, but is electronically protected against overload.
The anti-rotation strap supplied with the actuator will prevent
lateral movement.
The TLMB series provides 95° of rotation and a visual
indicator which indicates position of the actuator. When
reaching the damper or actuator end position, the actuator
automatically stops. The gears can be disengaged with
manual release on the actuator cover.
The TLMB24-3… actuators use a sensorless brushless DC
motor, which is controlled by an Application Specific Integrated
Circuit (ASIC). The ASIC monitors and controls the actuator’s
rotation and provides a digital rotation sensing (DRS) function
to prevent damage to the actuator in a stall condition. Power
consumption is reduced in holding mode.
Add on auxiliary switches or feedback potentiometers are easily
fastened directly onto the actuator body for signaling and
switching functions.
For all accessories, see pages 110 and 132.
