2. The actuator is usually shipped with the universal clamp mounted to the “CCW” installing contractor to allow space for mounting and service of the Belimo actuator on side of the actuator. To test for adequate shaft length, slide the actuator over the the shaft. - Page 18 Installation Instructions Mechanical Installation position the clamp so that the pointer section of the tab is pointing to 0° (see Multiple Actuator Mounting Figure C) and the spline pattern of the clamp mates with spline of the actuator. If more torque is required than one AFB, AFX actuator can provide, a second AFB, AFX Slip the clamp over the spline.
- Page 19 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-AFB position indicator. In order to function properly, the clamp or indicator must be mounted correctly. See Figure A.

The electromagnetic allows these actuators to track even the slightest deviation very accurately, yet poles are switched by a special ASIC circuit developed by Belimo. Unlike the allowing the actuator to “wait” for a much larger change in control signal due conventional DC motor, there are no brushes to wear or commutators to foul. -
