Series CRJ Specific Product Precautions Be sure to read before handling. Refer to front matter 35 for Safety Instructions and pages 4 to 4 for Rotary Actuator and Auto Switch Precautions. Caution Rotation Adjustment As a standard feature, the actuator with external stopper is equipped with a rotation angle adjustment screw that can be used to adjust the angle of rotation. Mounting of Speed Controller and Fittings Caution Angle adjustment per single rotation of angle adjustment screw 2.3 2.3 The rotation adjustment range for the actuator with external stopper is ±5 at each rotation end. Please note that adjusting beyond this range, may cause product malfunction. The M3 x.5 piping port is used. In case the speed controller or fittings are directly connected, use the series listed below. Speed controller AS2F/Elbow type AS3F/Universal type One-touch fitting One-touch mini Series KJ Reducer bushing Series M3 Caution External Stopper Assembly Procedure Actuators with external stopper (Model CRJU) come already assembled; therefore, the following procedure is not required. Caution External Stopper Unit Order external stopper unit with the unit part numbers shown below. Parts List Model Unit part no.

Note 2) When using external stoppers for 9, use Mini- rotary Actuators with a rotation range of, and for 8, use actuators with a rotation range of 9. Stopper Stopper retainer Hexagon socket head cap screw Caution Mounting of Auto Switch If a size actuator with auto switch is being used, keep the magnetic body away at least 2 mm or more from the bottom of the actuator. If the magnetic body comes closer than 2 mm, malfunction of the auto switch may occur due to the magnetic force drop. When using the bottom face for mounting, a non-magnetic spacer (such as aluminum) is required as shown below. Mini-rotary actuator Single flat Auto switch Non-magnetic spacer with a thickness of 2 mm or more. Mini-Rotary actuator Magnetic body.5 Caution Maintenance This product requires special tools; therefore, it cannot be disassembled for maintenance. 9 Fig. () Fig. (2). Assemble the stopper retainer to the stopper temporarily. Then place the stopper retainer in the single flat position and tighten with hexagon socket head cap screws. Leave a space of approximately.5 mm between the stopper and the Mini-rotary actuator, as shown in Fig. (). Tighten the hexagon socket head cap screws evenly so that the stopper retainer is not unevenly tightened as in Fig. (2). Furthermore, take precautions to avoid applying excessive force to the shaft when tightening. 2. Tighten the holder assembly with hexagon socket head cap screws.
