NMQB-MFT, NMQX-MFT Quick Proportional Control, Non-Spring Return, Direct Coupled, V, Multi-Function Technology Application For proportional modulation of dampers in HVAC systems. Actuator sizing should be done in accordance with the damper manufacturer s specifications. The actuator is mounted directly to a damper shaft up to.0 in diameter by means of its universal clamp, ½ self centered default. A crankarm and several mounting brackets are available for applications where the actuator cannot be direct coupled to the damper shaft. The default parameters for to 0 VDC applications of the actuator are assigned during manufacturing. If necessary, custom versions of the actuators can be ordered. The parameters can be changed by two means: pre-set and custom configurations from Belimo or on-site configurations using the Belimo PC-Tool software. (version. or later) Operation The actuator is not provided with and does not require any limit switches, but is electronically protected against overload. The anti-rotation strap supplied with the actuator will prevent lateral movement. The NMQB(X) series provides 9 of rotation and a visual indicator indicates position of the actuator. When reaching the damper or actuator end position, the actuator automatically stops. The gears can be manually disengaged with a button on the actuator cover. The NMQB(X)-MFT actuators use a Brushless DC motor, which is controlled by an Application Specific Integrated Circuit (ASIC). The ASIC monitors and controls the actuator s rotation and provides a digital rotation sensing (DRS) function to prevent damage to the actuator in a stall condition. Power consumption is reduced in holding mode. Add-on auxiliary switches or feedback potentiometers are easily fastened directly onto the actuator body for signaling and switching functions Dimensions (All numbers in brackets are in millimeters.).0 [].6 [88].7 [9].0 [77] Technical Data NMQB-MFT NMQX-MFT Power Supply VAC ±0% 0/60 Hz VDC ±0% Power Consumption W (.

Installation and Operation For Non-Spring Return Actuators Preliminary Steps. Belimo actuators with NEMA or NEMA 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: 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-00, ZG-0, ZG-0, ZG-0). Determining Torque Loading and Actuator Sizing Damper torque loadings, used in selecting the correct size actuator, should be provided by the damper manufacturer. If this information is not available, the following general selection guidelines can be used. Damper Type Opposed blade, without edge seals, for nontight close-off applications Parallel blade, without edge seals, for non-tight close-off applications Opposed blade, with edge seals, for tight closeoff applications Parallel blade, with edge seals, for tight closeoff applications Torque Loading in-lb/sq. ft. in-lb/sq. ft. in-lb/sq. ft. 7 in-lb/sq. ft. The above torque loadings will work for most applications under w.g. static pressure or 000 FPM face velocity. For applications between this criteria and w.g. or 00 FPM, the torque loading should be increased by a multiplier of.. If the application calls for higher criteria up to w.g. or 000 FPM, use a multiplier of.0. Torque Loading Chart 0 Damper Area (sq. ft.) 0 00 80 60 0 0 0 6 7 8 9 0 Torque Loading (in-lb/sq. ft.)

Reversible Clamp Quick Mount (LMQB, NMQB, and AMQB) Standard Mounting. Turn the damper shaft until the blades are fully closed.. 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. 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 recommended).. Loosen the nuts on the universal clamp. Press the manual override button and rotate the clamp to about from the closed position (¹ ₁₆ to ¹ ₈ between stop and clamp). Tighten the two nuts on the universal clamp with a 0 mm wrench (see table for required torque).. Snap on the reflective position indicator. Adjust end-stops, if required 6. Mount actuators indoors. If mounted outdoors, use approved protective enclosure. The damper is now fully closed but the actuator is from fully closed. This is called pre-loading 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 electronically protected from overload and will not be damaged. Testing the Installation Without Power. 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 of actuator stroke left.. Correct any problems and retest.
