Features and Benefits
Brushless DC Motor Technology
Belimo new generation actuators all employ
state-of-the-art halomo sensorless, brushless DC
motor technology. The halomo technology was
developed exclusively by Belimo’s Technology
division and enables Trane to offer the high quality
of brushless DC motor technology inside all actuator
models in the new generation.
With the increase in product lifespan and quality
the TLM series creates a new level of expectation
for actuators installed in VAV applications.
●Only ONE moving part!
●No brushes to wear out
●Position feedback is generated by ASIC
●Overload proof; uses integrated end stop filtering
●Running noise is reduced to absolute minimum

Damper Actuators
●Extensive product range.
●Specific retrofit offerings.
●Small dimensions in relation to torque.
●Microprocessor-controlled Brushless
DC motor increases actuator life span
and reliability & provides constant
running time (most actuators).
●Cut labor costs with simple direct
coupling.
●Check damper position easily with
clear position indication.
●Overload-proof throughout rotation.
●Temporary restrictions in damper
movement will not change actuator
operation. Actuator returns to normal
operation when restriction is remove.
●Built-in or add-on mechanical stops to
adjust angle of rotation.
●Built-in auxiliary switch is easy to use,
offers feedback or signal for additional
device (-S models).
●Need to change control direction?
Do it easily with a simple switch on
actuator housing.
●Rugged housings withstand rough
handling in the mechanical room.
●Automatically compensates for
damper seal wear, ensuring tight
close off.
Spring Return
●True mechanical spring return – the
most reliable fail-safe.
●Reverse mount for clockwise or
counterclockwise fail-safe.
●Manual override crank speeds
installation (TAF Series).
●3 ft. appliance cable and conduit
connector eases installation.
Non-Spring Return
●Increased torque output by up to 28%
●More mounting flexibility –
TLM accepts 3/4" dia. shafts,
TNM, TAM & TGM mounts to 1.05"
dia. jackshafts.
●New optional external auxiliary
switch(es) or position feedback
potentiometer modules – same
modules for all non-spring return
actuators!
●Manual override push button.
●Compatible to discontinued models.

The “10 questions” method for sizing and selection is recom-
mended as the best method for your actuation requirements.
Use the ‘Application Data’ column in this chart as a worksheet
to help in the selection process. This data, along with the
‘Actuator Product Range’ charts on pages 2 and 3, allow for the
best selection of a Trane actuator.

Sizing and Selecting Actuators
This will impact
the proper
selection as the
seals add resist-
ance requiring
more torque.
If this informa-
tion is not
available refer
to the “typical

chart.
Systems above 1,000 FPM
require additional actuator torque

Consider the application. Is the actu-

use spring return.
• Two position
• Floating point
• Modulating
• Sequencing
• “Non-standard”

This will be a critical component to the
damper selection of an actuator.

Do you need
a step down
transformer?
If replacing an oil
immersed gear
train actuator. Is
the transformer in the defective actua-
tor? You may need to purchase one.
Direct cou-
pling has
become the
industry stan-
dard. Some
retrofit appli-
cations do not
allow direct
coupling.
Some applications require the additions of
an auxiliary switch for proof of position. Or
a retrofit application may require an addi-
tional mounting bracket and linkage kit.
You must identify these needs prior to
leaving the job site or ordering products.

Control Signal Overview
Trane actuators are compatible with many control inputs. There
are many signals to select from with today’s controllers.
What does ‘on-off’, ‘open-close’, ‘3-point’, ‘tri state’, ‘floating point’,
‘proportional modulation’, mean?
Trane will help you understand more on this control signal
jungle with a quick overview:
On-Off or Open-Close: The actuator is able to drive either to
its full open position, or to its full closed position. The same
indication is used for Spring return type actuators. However the
actuator will drive to its full open position and spring return to its
zero position. This can also be reversed.
3-Point, Tri-state, Floating Point: The actuator has both clock-
wise (CW) and counter-clockwise (CCW) control inputs. One
drives the actuator to its open, the other to its close position. If
there is no signal (Null point) on either input the actuator simply
stays in its last position.
Proportional Control: The Actuator drives proportional to its
control input and modulates through-out its angle of rotation. This
control type is usually a variation of VDC. Common values are:
0-10 VDC 2-10 VDC
It is common to also have a 0-20 mA output from a controller.
This can be very easily converted to 0-10VDC or 2-10 VDC
with a 500Ωresistor.
