Application
For proportional modulation of dampers in HVAC systems.
Actuator sizing should be done in accordance with the damper manufacturer’s specifications. The actuator mounts directly to the damper operating shaft with a universal V-bolt clamp assembly. The actuator operates in response to a 2 to 10 VDC or, with the addition of a 500
Ω resistor, a 4 to 20 mA input signal from an electronic controller or positioner. A 2 to 10 VDC feedback signal is provided for position indication or master slave applications. (Not available on “-T” versions)
The LM24SR
US provides an electronic angle of rotation adjustment to limit the actuators rotation 20% to 100% while still using the full input signal and feedback control range. (Not available on LM24SR-T
US
)
Operation
The anti-rotation strap supplied with the actuator will prevent lateral movement of the actuator. The damper actuator is not provided with and does not require any limit switches, but is protected electronically against overload. The angle of rotation is mechanically limited to 95°. When reaching the damper or actuator end position, the actuator automatically stops. The gears can be manually disengaged by pressing a button on the actuator cover. The position of the actuator is indicated by a visual pointer.

Preliminary steps
1.
Belimo actuators should be mounted indoors in dry, relatively clean environment free from corrosive fumes. If the actuator is to be mounted outdoors, a protective enclosure must be used to shield the actuator. (See Belimo Mechanical Accessories Doc. 5.2)
2.
For new construction work, order dampers with extended shafts. Instruct the installing contractor to allow space for mounting and service of the Belimo actuator on the shaft.
3.
The LM Series actuator requires a minimum shaft length of 1.5”.
Use the ZG-LMSA for short shaft installations on 1/2” diameter shafts.

Installation Instructions
General Wiring
WARNING The wiring technician must be trained and experienced with electronic circuits. Disconnect power supply before attempting any wiring connections or changes. Make all connections in accordance with wiring diagrams and follow all applicable local and national codes. Provide disconnect and overload protection as required. Use copper, twisted pair, conductors only.
Always read the controller manufacturer's installation liter-
ature carefully before making any connections. Follow all instructions in this literature. If you have any questions, contact the controller manufacturer and/or Belimo.
Transformer(s)
The LM Series actuators require a 24 VAC transformer and draw a maximum of 4 VA.
CAUTION: It is good practice to power electronic or digital controllers from a separate power transformer than that used for actuators or other end devices. The power supply design in our actuators and other end devices use half wave rectification.
Some controllers use full wave rectification. When these two different types of power supplies are connected to the same power transformer and the DC commons are connected together, a short circuit is created across one of the diodes in the full wave power supply, damaging the controller. Only use a single power transformer to power the controller and actuator if you know the controller power supply uses half wave rectification.
Multiple actuators, one transformer
Multiple actuators may be powered from one transformer provided the following rules are followed:
1. The TOTAL current draw of the actuators (VA rating) is less than or equal to the rating of the transformer.
2. Polarity on the secondary of the transformer is strictly followed.
This means that all No. 1 wires from all actuators are connected to the common leg on the transformer and all
No 2 wires from all actuators are connected to the hotleg.
Mixing wire No. 1 & 2 on one leg of the transformer will result in erratic operation or failure of the actuator and or controls.
Multiple actuators, multiple transformers
Multiple actuators positioned by the same control signal may be powered from multiple transformers provided the following rules are followed:
1. The transformers are properly sized.
2. All No. 1 wires from all actuators are tied together and tied to the negative leg of the control signal. See wiring diagram.
Wire length for LM Series actuators
Keep power wire runs below the limits listed in the Fig. 1. If more than one actuator is powered from the same wire run, divide the allowable wire length by the number of actuators to determine the maximum run to any single actuator.
Maximum wire length:

Example for LM…
US
: 3 actuators, 18 Ga wire
725 Ft ÷ 3 Actuators = 241.6 Ft. Maximum wire run.
Wire Type and Wire Installation Tips
For most installations, 18 or 16 Ga. cable works well with the
LM24 type actuators. Use code approved wire nuts, terminal strips or solderless connectors where wires are joined. It is good practice to run control wires unspliced from the actuator to the controller. If splices are unavoidable, make sure the splice can be reached for possible maintenance. Tape and/or wire tie the splice to reduce the possibility of the splice being inadvertently pulled apart.
LM Series Actuators with Terminal Strip
LM…-T actuators feature an external screw terminal strip on the top of the actuator housing (instead of cable). Connections are numbered and a wiring schematic is shown next to the terminal strip. The terminals are designed for 26 to 14 GA wire.
Overload protection
All Belimo actuators are electronically protected against overload. In the LM series an electronic circuit maintains the current at a level which will not damage the motor while providing adequate holding torque.
Manual Override
A button on the actuator cover disengages the gear train so the damper shaft can be moved manually. Release the button and the gear train is re-engaged.
Use the manual override to test the installation without power. For tight shut-off the damper should close with 5° of actuator stroke left.

Feature Operation
Installation Instructions
Direction of Rotation Switch (All LM except LM24-T
US
, LM24-5P0-T
US
)
LM actuators have a reversing switch on the cover labeled “L-R”.
Switch position indicates start point. For the LM24SR(-T), with the switch in position “L”, the actuator rotates clockwise with an increase in voltage or current. With the switch in position “R”, the actuator rotates counterclockwise with an increase in voltage or current.
During checkout, the switch position can be temporarily reversed and the actuator will reverse its direction. This allows the technician a fast and easy way to check the actuator operation without having to switch wires or change settings on the thermostat.
When the check-out is complete, make sure the switch is placed back to its original position.
The LM24 (-S)
US and LM24-10P
US rotate clockwise when the switch is in the “R” position and power is applied to wire #2. When power is applied to wire #3 the actuator rotates counter clockwise.
Rotating the “L/R” switch to “L” reverses the control logic.

Mechanical Angle of Rotation Limiting (LM Series, On-Off/Floating and LM24SR-T
US
)
The adjustable stops are needed when there is no damper stop or if you want the damper to halt rotating before it reaches its stops. The LM actuator can be indefinitely stalled in any position without harm.
1. Loosen the two end stops with a No. 2 Phillips head screwdriver being careful not to unscrew the captive nut under the slot.
2. Move the stops (in 2.5° steps) to the desired position and retighten the screws.

With the LM24SR
US proportional actuator, you can adjust the angle of rotation (95°) anywhere between 20% and 100% using an external adjustment. A potentiometer limits rotation while allowing the full control input and feedback range (2 to 10
VDC), providing higher control resolution within the limited angle of rotation.

Adjustable Auxiliary Switch (LM24-S
US
)
The LM24-S
US actuator is equipped with an adjustable auxiliary switch used to indicate damper position or to interface additional controls or equipment. Switching positions can be set over the full scale of 0 to 95° simply by setting switch on the actuator cover.
Method A
1. Set desired switch position. (Example 60%)
2. As the actuator rotates, the switch indicator moves from
60% toward 0%. When the indicator passes 0 the switch contact between S1 and S3 is broken and the contact between S1 and S2 is made.
Method B
1. Use manual override to position universal clamp to desired switch position.
2. Turn switch pointer to “0”.

Explanation: The diode allows the positive (+) signal to pass through it and does not allow a higher level positive signal to back feed to the other controller. Only the highest controller signal is seen by the actuator. There is a .7 VDC voltage loss across the diode. This makes the actual voltage range 2.7 to 10.7 VDC.

Check input signal with a digital volt meter (DVM). Make sure the input is within the range of the actuator. For
LM24SR(-T)
US this is 0 to 10 VDC or
0 to 20 mA.
Note: The input signal must be above the 2 VDC or 4 mA to have the actuator move.
Input voltage or current should be ±1% of what controller's adjustment or programming indicate.
Use the manual override button to move the damper by hand from fully closed to fully open.
Damper will go from fully closed to fully open.

8.
Actuator works properly. Test controller by following controller manufacturer's instructions.
Note 1
Check that the transformer(s) are sized properly.
• If a common transformer is used, make sure that polarity is observed on the secondary. This means connect all No. 1 wires to one leg of the transformer and all No. 2 wires to the other leg of the transformer.
• If multiple transformers are used with one control signal, make sure all No. 1 wires are tied together and tied to control signal negative (-).
• Controllers and actuators must have separate 24 VAC/VDC power sources.
Note 2
If failure occurs within 5 years from original installation date, notify Belimo and give details of the application.
