General Information
Preliminary Steps
. Belimo actuators with NEMA 1 or NEMA 2 ratings should be mounted indoors in
a dry, relatively clean environment free from corrosive fumes. If the actuator is
mounted outdoors, a protective enclosure must be used to shield the actuator.
. For new construction work, order dampers with extended shafts. Instruct the
installing contractor to allow space for mounting the Belimo actuator on the shaft.
For replacement of existing gear train actuators, there are two options:
. From a performance standpoint, it is best to mount the actuator directly onto the
damper shaft.
. If the damper shaft is not accessible, mount the non-spring return actuator with
a ZG-NMA or ZG-GMA crank arm kit, and a mounting bracket (ZG-100, ZG-101,
ZG-103, ZG-104
Determining Torque Loading and Actuator Sizing
amper torque loadings, used in selecting the correct size actuator, should be pro
vided by the damper manufacturer. If this information is not available, the following
eneral selection guidelines can be used
amper Type
Opposed blade, without edge seals, for
ht close-off application
non-ti
Parallel blade, without edge seals, for
non-ti
ht close-off application
pposed blade, with edge seals, for tight
close-off application
Parallel blade, with edge seals, for tight
close-off application
he above torque loadings will work for most applications under 2 in. w.g. static
ressure or 1000 FPM face velocity. For applications between this criteria and 3 in.
w.g. or 2500 FPM, the torque loading should be increased by a multiplier of 1.5. If
the application calls for higher criteria up to 4 in. w.g. or 3000 FPM, use a multiplier
of 2.0

Hand tighten the two nuts on the actuators universal clamp.

Disengage the actuator gear train by pressing the manual override button
and rotate the clamp until centered.
Slide the anti-rotation strap up under the actuator so it engages the
actuator at the center cutout. Bend the bracket as needed to support the rear
of the actuator. Secure to ductwork with self-tapping screws (No. 8 recom

4
Loosen the nuts on the universal clamp. Press the manual override
utton and rotate the clamp to about 5° from the closed position (1/16 to 1/8”
etween stop and clamp).
Tighten the two nuts on the universal clamp with a 10 mm wrench (see

Mount actuators indoors. If mounted outdoors, use approved protective enclosure.
e. Place the actuator in the

“pre-loading” the actuator. When the actuator is powered and sent to the closed
osition: it will put its full torque on the shaft compressing the edge and blade seals.
his ensures that the damper will meet its leakage rating. The actuator is electroni
ally protected from overload and will not be damaged.
Testing the Installation Without Powe
. Disengage the gear train with the manual override button and move the shaft
from closed to open to closed. Ensure that there is no binding and that the
damper goes fully open and closes with 5° of actuator stroke left
. Correct any problems and retest.

en replacing an actuator, whether Belimo or other, be sure to consider the ap
lication parameters before selecting the replacement. The new product may not
e the best fi t for the application. Example would be a Belimo AM24 US mounted
to a valve linkage. The direct replacement of the actuator is AMB24-3. However,
the AM24 US and the AMB24-3 are different lengths, the linkage would need to be
laced as well
Instead of replacing the linkage the retrofi t bracket Z-SMA and Z-GMA can be used
to extend the location of the anti-rotation bracket to match the location of the anti
otation bracket of discontinued Belimo actuators
NOTE: LM and LMB are the same size.

Electrical Operation
eneral
elimo non-spring return actuators utilize Halomo sensorless Brushless DC motor
echnology developed by Belimo. The non-spring return actuators use this motor in
onjunction with an Application Specific Integrated Circuit (ASIC). The Halomo ASIC
provides the intelligence to provide a constant rotation rate to prevent damage to
Initializati
When a power source is applied the motor carries out an initialization of the
actuator. The purpose of this initialization is to determine the mechanical angle of
rotation and to adapt the running time to the angle of rotation. When power is
applied, the internal microprocessor recognizes that the actuator is at its full-safe
position and uses this position as the base for all of its calculations.
Brushless DC Motor Operation
elimo’s Halomo sensorless brushless DC motor spins by reversing the poles of
stationary electromagnets housed inside rotation permanent magnets. The
lectromagnetic poles are switched by a special ASIC developed by Belimo. Unlike
he conventional DC motor, there are no brushes to wear or commutators to foul.
Motor Position Detect
elimo's Halomo motor technology is a sensorless, brushless DC motor. The
alomo technology eliminates the need for potentiometers for positioning. The
alomo ASIC detects the spinning rotor by monitoring the back EMF of the motor
poles. The ASIC counts these pulses and calculates position within 1/3 of a motor
revolution
Overload Protection
The Belimo non-spring return actuators are electronically protected from overload at
all angles of rotation by digital technology in the ASIC. The ASIC circuitry constantly
monitors the rotation of the brushless DC motor inside the actuator and stops the
pulsing to the motor when it senses an overload. The motor remains energized an
produces full rated torque when in overload.
The overload filtration helps increase the actuators installed life expectancy by
iltering out unnecessary control signal changes or end-stop pulsing while in
overload. This helps ensure that dampers are fully closed and that edge and blade
seals are always properly compressed
Control Accuracy and Stability

brushless DC motors which provide
better accuracy and lon
elimo non-spring return actuators are designed with a unique non
ymmetrical deadband. The actuator follows an increasing or decreasing
ontrol signal with a 75 mV resolution. If the signal changes in the opposite
irection, the actuator will not respond until the control signal changes by
75 mV. This allows these actuators to track even the slightest deviation very
ccurately, yet allowing the actuator to “wait” for a much larger change in
ontrol signal due to control signal insta

Use the manual override to test the installation without power. For tight shut-off the
damper should close with 5° of actuator stroke left.

Manual Override Button
Non-spring return actuators have a reversing switch on the cover. Switch position

actuator rotates clockwise with an decrease in voltage or current. With the switch
