. Rotate the damper to its

ail-sa

e position

If the shaft rotates counterclockwise

mount the “

W” side of the actuator out

If it rotates clockwise, mount the actuator with the “

W” side out.

. I

the universal clamp is not on the correct side o

the actuator, mount it onto the correct side

3. Slide the actuator onto the shaft and ti

hten the nuts on the V-bolt with a 13mm wrench to 11 ft-lb of torque

4. Slide the anti-rotation strap under the actuator so that it engages the slot at the base of the actuator. Secure the strap to the duct work with #8 self-tapping screws.

Installation Instructions Quick-Mount Visual Instructions for Mechanical Installation Quick-Mount Visual Instructions 1. Rotate the damper to its fail-safe position. If the shaft rotates counterclockwise, mount the “CCW” side of the actuator out. If it rotates clockwise, mount the actuator with the “CW” side out. 2. If the universal clamp is not on the correct side of the actuator, mount it onto the correct side. 3.

Installation Instructions Mechanical Installation 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.

Installation Instructions Mechanical Installation 4. 5. 6. 7. 8. 9. position the clamp so that the pointer section of the tab is pointing to 0° (see Figure C) and the spline pattern of the clamp mates with spline of the actuator. Slip the clamp over the spline. (Use the same procedure if the “CW” side is out.) If your application requires a mechanical minimum position, read the Rotation Limiting, Mechanical Minimum Damper Positionn section. Lock the clamp to the actuator using the retaining clip.

Installation Instructions Mechanical Installation Rotation Limitation The angle of rotation limiter, which is built into the actuator, is used in conjunction with the tab on the universal clamp or IND-EFB position indicator. In order to function properly, the clamp or indicator must be mounted correctly. See Figure A. The rotation limiter may not work in certain mounting orientations using the ZG-EFB mounting kit. Limiting the damper rotation must be accomplished by adjusting the crank arm linkage.

Installation Instructions Mechanical Installation Manual Override Auxiliary Switches The EFB, EFXX series actuators can be manually positioned to ease installation or for emergency positioning. The EFB, EFX series actuators may be ordered with two built-in SPDT auxiliary switches used for safety interfacing or signaling, for example, for fan start-up. The switch position near the fail-safe position is fixed at 10°.

Installation Instructions Non-Direct Mounting Methods KH EFB Crank KH-EFB C k Arm A Including Retaining Ring The KH-EFB crank arm is used in non-direct coupled mounting applications. The KHEFB may also be used to simultaneously direct couple to a damper shaft and provide an additional crank arm connection to a second damper.

Installation Instructions Electrical Operation General Control Accuracy and Stability The EFB, EFX series actuators utilize both DC Motors and brushless DC motor technology. The EFB, EFX uses this motor in conjunction with an Application Specific Integrated Circuit (ASIC). In the On/Off versions of the EFB and EFX, the ASIC monitors and controls the actuator’s rotation and a digital rotation sensing function to prevent damage to the actuator.

Installation Instructions General Wiring Instructions 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.

Control signal is applied to actuator. Actuator will move to its “Control Signal” position. Actuator operates properly Step 7. No response at all Step 2. Operation is reversed Step 3. Does not drive toward "Control Signal Position" Step 4. 2. Check power wiring. Correct any problems.
