Rotary Movement The (clockwise or counterclockwise) can be selected using the (see part 7 in Fig. ), thus eliminating the need to re-wire. To ensure tight closing of the dampers, the actuator has a total stroke of 95. As soon as operating power is applied, the actuator may start to run. When power is removed, the actuator remains in position. For actuatorcontroller wiring instructions, see section Wiring on page 4. Fig.. Setting units and control elements 上海君琼空调科技有限公司

If you have additional questions, need further information, or would like to comment on our products or services, please write or phone your local Honeywell Automation and Control Products Sales Office or Honeywell Customer Care. Rotation ection Switch Manual Adjustment IMPORTANT To prevent equipment damage, you must remove power or set the to the position before manual adjustment. After removing power or setting the to the position, the gear train can be disengaged using the declutch button, permitting the actuator shaft to be manually rotated to any position. The feedback signal will then follow the new position. Fig.. Rotation ection Switch (" ") is the default shipping position. When the is set to this position, the actuator internally es the control signals as stated in section "Wiring Diagrams" on pages 4 and 5. "": When the is set to this position, all actuator rotary movement is cancelled and all control signals are ignored, thus enabling the actuator to be manually operated (see section "Manual Adjustment"). The user can then perform maintenance / commissioning without having to remove power from the actuator. To return to the control mode, simply move the to its former setting. (" "): When the is set to this position, the actuator follows signals as stated in section "Wiring Diagrams" on pages 4 and 5. Two-Position or Floating Control The actuator is capable of being operated by either a twoposition (open/close) or a floating (three-wire) controller. Refer to wiring diagrams for correct connection. Limitation of Rotation Stroke Two adjustable mechanical end limits ( Nm [77 lb-in] models, only) are provided to limit the angle of as desired (see Fig.5). Fig. 5. Mechanical end limits The mechanical end limits must be securely fastened in place as shown in Fig. 6. Specifically, it is important that they properly mesh with the al angle scales when the screws are tightened. Position Indication The hub adapter indicates the angle position by means of the al angle scales (...9 / 9... ) provided in the actuator plate (see Fig. 4). 9 9 Fig.6.

4 N, N4 SERIES CN6, CN64, CN46, CN464 INSTALLATION These actuators are designed for single-point mounting. IMPORTANT In order to prevent equipment damage, you must remove power or set the to the position before manual operation. Mounting Instructions All information and steps are included in the Installation Instructions supplied with the actuator. Wiring Access Cover To facilitate wiring the actuator to the controller, the access cover can be detached from the actuator. IMPORTANT Remove power before detaching the access cover. Once the access cover has been removed, please take care to avoid damaging any of the parts now accessible. Mounting Position The actuators can be mounted in any position (no or NEMA if mounted upside down; see Fig. 7). Choose a mounting position permitting easy access to the actuator's cables and controls. Fig. 8. Access cover Depending upon the model, the access cover may have one or two terminal strips, including a layout with a description for each of the terminals. Fig. 7. Mounting for Mounting Bracket and Screws If the actuator is to be mounted directly on a damper shaft, use the mounting bracket and screws included in the delivery package. Self-Centering Shaft Adapter The self-centering shaft adapter can be used for shafts having various diameters (...7 mm [/8...-/6 ]) and shapes (square or round) Fig. 9. Actuator with access cover removed In the case of short shafts, the shaft adapter may be reversed and mounted on the duct side. Stroke Limitation with Mechanical End Limits The mechanical end limits ( Nm [77 lb-in] models, only) enable the stroke to be limited from...9 in increments of. 4 上海君琼空调科技有限公司
