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

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.
