[. . . ] at 1 m N2024 / N20230 N3424 / N34230 PRODUCT DATA GENERAL These direct-coupled damper actuators provide two-position and floating control for: · air dampers, · VAV units, · air handlers, · ventilation flaps, · louvers, and · reliable control for air damper applications with up to 4. 6 m2 / 50 sq. ft. (34 Nm / 300 lb-in) (seal-less dampers; air frictiondependent). FEATURES · · · · · · · · New self-centering shaft adapter Access cover to facilitate connectivity Declutch for manual adjustment Mechanical end limits Field-installable auxiliary switches Rotation direction selectable by switch Mountable in any orientation (no IP54 if upside down) Mechanical position indicator ® U. S. Registered Trademark Copyright © 2009 Honeywell Inc. [. . . ] Rotation Direction Switch Dir (" ") is the default shipping position. When the rotation direction switch is set to this position, the actuator internally switches the rotation direction control signals as stated in section "Wiring Diagrams" on pages 5 and 6. "Service/Off": When the rotation direction switch 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 rotation direction switch to its former setting. Rev (" "): When the rotation direction switch is set to this position, the actuator follows signals as stated in section "Wiring Diagrams" on pages 5 and 6. Manual Adjustment IMPORTANT To prevent equipment damage, you must remove power or set the rotation direction switch to the "Service/Off" position before manual adjustment. After removing power or setting the rotation direction switch to the "Service/Off" 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. Limitation of Rotation Stroke Two adjustable mechanical end limits (20 Nm [177 lb-in] models, only) are provided to limit the angle of rotation as desired (see Fig. 6). Two-Position or Floating Control The actuator is capable of being operated by either a twoposition (open/close) or (unless explicitly identified as a 2POS model) a floating (three-wire) controller. Refer to wiring diagrams for correct connection. Feedback Signal Actuators equipped with a feedback potentiometer provide position feedback via the potentiometer resistance value (see Fig. =0 ENSURE PROPER MESHING OF TEETH P2 totally CCW totally CW =0 = max. Feedback signal settings If, while the actuator is not rotating, the user declutches it and manually repositions the shaft adapter, the feedback signal will then follow the new position at which the shaft adapter has been left. Fig. Mechanical end limits The mechanical end limits must be securely fastened in place as shown in Fig. Specifically, it is important that they properly mesh with the rotational angle scales when the screws are tightened. Position Indication The hub adapter indicates the rotation angle position by means of the rotational angle scales (0. . . 90° / 90. . . 0°) provided in the actuator plate (see Fig. 5). 3 EN0B-0320GE51 R0409 SmartAct N2024 / N20230, N3424 / N34230 CORRECT INCORRECT INSTALLATION These actuators are designed for single-point mounting. IMPORTANT In order to prevent equipment damage, you must remove power or set the rotation direction switch to the "Service/Off" position before manual operation. Mounting Instructions CORRECT INCORRECT All information and steps are included in the Installation Instructions supplied with the actuator. Mounting Position The actuators can be mounted in any position (no IP54 if mounted upside down; see Fig. Choose a mounting position permitting easy access to the actuator's cables and controls.
