Jackshaft Installation (MS40-7043 Series) The MS40-7043 actuator is designed for use with jackshafts up to 3/4" (19 mm) in diameter. In most applications, the MS40-7043 actuator may be mounted in the same manner as a standard damper shaft application. If the jackshaft diameter is larger than 5/8" (16 mm) in diameter, the optional AM-710 universal clamp must be used. (MS4X-7153 and MS4X-7073 Series) The MS4X-7153 and MS4X-7073 actuators are designed for use with jackshafts up to 1.05" (27 mm) in diameter.
Wiring Requirements Control Leads See Table-3 for power wiring data. Refer to Figure-1 and Figure-2 for typical wiring. Table-3 Power Wiring. Actuator Voltage Maximum Wire Run in ft.
Rotation Limitation Rotation Limitation for MS40-7043 Series The Stop Block is used in conjunction with the tab on the universal clamp or the AM-709 position indicator. In order to function properly, the clamp or indicator must be mounted correctly. The Stop Block controls the rotational output of the MS40-7043 and MF40-7043-501 actuators. It is used in applications where a damper has a designed rotation that is less than 90°, for example with a 45° or 60° rotating damper.
Rotation Limitation for MS4X-7153 and MS4X-7073 Series The AM-689 rotation limiter is used in conjunction with the tab on the universal clamp or the AM-686 position indicator which comes with the AM-689. In order to function properly, the clamp or indicator must be mounted correctly. The AM-689 rotation limiter controls the rotational output of the MS4X-7153, MS4X-7153502, MS4X-7073, and MS4X-7073-502 actuators.
Minimum Damper Positioning Note: When using the AM-689 rotation limiter with an MS4X-7073 or MS4X-7153 actuator to provide a minimum damper position, the short shaft mounting procedure must be used to mount the actuator. Caution: • The AM-689 rotation limiter should not be used with an MS4X-7073 or MS4X-7153 actuator to provide a minimum damper position in outdoor air damper applications. The rotation limiter prevents the damper from reaching the full-closed position.
CHECKOUT After the entire system has been installed and the actuator has been powered up, the following check can be made for proper system operation. Check for correct operation of the damper while actuator is being stroked. 1. Apply power to the actuator. Actuator and damper should be driven to their powered position as determined by the control signal. 2. On the MS4X-7XXX-50X models, check for correct auxiliary switch operation. 3. Break power to the actuator.
MAINTENANCE Regular maintenance of the total system is recommended to assure sustained optimum performance. The MS4X series actuators are maintenance free. FIELD REPAIR None. Replace with a functional actuator.
