description

For proportional modulation of dampers in HVAC systems.Actuator sizing should be done in accordance with thedamper manufacturer’s specifications.The actuator is mounted directly to a damper shaft up to 1.05”in diameter by means of its universal clamp, 1/2” self-centereddefault. A crankarm and several mounting brackets are availablefor applications where the actuator cannot be direct coupledto the damper shaft.The actuator operates in response to a 2 to 10 VDC, or withthe addition of a 500Ω resistor, a 4 to 20 mA control inputfrom an electronic controller or positioner. A 2 to 10 VDCfeedback signal is provided for position indication or masterslaveapplications.OperationThe actuator is not provided with and does not require anylimit switches, but is electronically protected against overload.The anti-rotation strap supplied with the actuator will preventlateral movement.The AMB series provides 95° of rotation and a visual indicatorindicates position of the actuator. When reaching the damper oractuator end position, the actuator automatically stops. The gearscan be manually disengaged with a button on the actuator cover.The AMB24-SR… actuators use a sensorless Brushless DCmotor, which is controlled by an Application SpecificIntegrated Circuit (ASIC). The ASIC monitors and controls theactuator’s rotation and provides a digital rotation sensing(DRS) function to prevent damage to the actuator in a stallcondition. Power consumption is reduced in holding mode.Add on auxiliary switches or feedback potentiometers areeasily fastened directly onto the actuator body for signalingand switching functionsDimensions (All numbers in brackets are in millimeters.)5.47” [139]2.2” [56]2.49” [63.4]4.3” [109]1.18”[30]3.46” [88]5/16”

General Information

Preliminary steps1. 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 mount-ed outdoors, a protective enclosure must be used to shield the actuator.

2. For new construction work, order dampers with extended shafts. Instruct the install-ing contractor to allow space for mounting the Belimo actuator on the shaft.

For replacement of existing gear train actuators, there are two options:

A. From a performance standpoint, it is best to mount the actuator directly onto the damper shaft.

B. If the damper shaft is not accessible, mount the non-spring return actuator with a ZG-NMA or ZG-GMA crankarm kit, and a mounting bracket (ZG-100, ZG-101, ZG-103, ZG-104).

10 VDC 2 VDC 10 VDC2 VDC

Direction of Rotation Switch

Non-spring return actuators have a reversing switch on the cover. Switch position indicates start point. For the non-spring return, with the switch in position 1, the actuator rotates clock-wise with a decrease in voltage or current. With the switch in position 0, the actuator rotates counterclockwise with a decrease in voltage or current.

The non-spring return rotates clockwise when the switch is in the 1 position and power is applied to wire #2. When power is applied to wire #3 the actuator rotates counter clockwise.Rotating the switch to 0 reverses the control logic.

During checkout, the switch position can be tem-porarily 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 …-S model actuators are equipped with an adjustable auxiliary switch used to indicate damp-er position or to interface additional controls or equipment. Switching positions can be set over the full 0 to 95° rotation simply by setting a switch on the actuator.

1. Turn the damper shaft until the blades are fully closed.

2. ① Slip the actuator’s universal clamp over the damper shaft. Make sure that the duct and the controls on the cover are accessible. Place the actuator in the desired mounting position.

➁ Hand tighten the two nuts on the actuators universal clamp.

3. ① Disengage the actuator gear train by pressing the manual override button and rotate the clamp until centered.

➁ Slide the anti-rotation strap up under the actuator so it engages the actuator at the center of the cutout. Bend the bracket as needed to support the rear of the actuator. Secure to ductwork with self-tapping screws (No. 8 recommended).

4. ① Loosen the nuts on the universal clamp. Press the manual override button and rotate the clamp to about 5° from the closed position (1/16 to 1/8” between stop and clamp).

➁ Tighten the two nuts on the universal clamp with a 8, 10 or 12mm wrench (see table, column D on page 2 for required torque).

5. ① Snap on the reflective position indicator. ➁ Adjust end-stops, if required6. Mount actuators indoors. If mounted out-

doors, use approved protective enclosure. The damper is now fully closed but the actuator is 5° from fully closed. This is called “pre-load-ing” the actuator. When the actuator is powered and sent to the closed position: it will put its full torque on the shaft compressing the edge and blade seals. This ensures that the damper will meet its leakage rating. The actuator is elec-tronically protected from overload and will not be damaged.

Testing the installation without power1. 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.

2. Correct any problems and retest.

Manual Override

The Belimo non-spring return actuators have a black, “manual override button” located on the top of the housing. Press this button and the gear train is disengaged 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 installa-tion without power. For tight shut-off the damper should close with 5° of actuator stroke left.

Manual override

OperationsMechanical Features

®

Mechanical Angle of Rotation Limiting

The adjustable stops are needed when there is no damper stop or if you want the damper to stop rotating before it reaches its stops. The non-spring return actuators 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 re-tighten the screws.
