G Issued May 2021 Applications The M9203-AGx-2(Z) Series On/Off and Floating Point Electric Spring Return Actuators are direct-mount actuators that operate on AC/DC 24 V power. These bidirectional actuators do not require a damper linkage, and are easily installed on round shafts from 1/4 to 1/2 in. (6 to 12 mm) or square shafts from 1/4 to 5/16 in. (6 to 8 mm) using the standard shaft clamp included with the actuator. A single M9203-AGx-2(Z) Series On/Off and Floating Point Electric Spring Return Actuator provides 27 lb·in. (3 N·m) running and spring return torque. An integral line voltage auxiliary switch, available only on the M9203-xxB-2(Z) models, indicates end-stop position, or performs switching functions within the selected rotation range. M9203-AGA-2(Z) actuators include plenum-rated cables and are specially configured for installation in spaces used for environmental air-handling purposes other than ducts and plenums as specified in National Fire Protection Association (NFPA) 70: National Electrical Code section 300.22(C), Other Space Used for Environmental Air. The space over a hung ceiling used for environmental air handling purposes is an example of the type of space for which these actuators are configured. IMPORTANT: Use this M9203-AGx-2(Z) Series On/Off and Floating Point Electric Spring Return Actuator only to control equipment under normal operating conditions. Where failure or malfunction of the actuator could lead to personal injury or property damage to the controlled equipment or other property, additional precautions must be designed into the control system.

Positioning the tab midpoint in the slot prevents actuator binding and premature wear, and makes actuator removal easier. 2-1/4 (57.5) 3-1/4 (82.5) Self-Drilling Sheet Metal Screws (2) Anti-Rotation Bracket 7. Hold the actuator perpendicular to the damper shaft. Evenly hand-tighten each nut on the coupler U-bolt, then torque the coupler U-bolt nuts to 100 to 125 lb·in. (11 to 14 N·m). 8. Apply power long enough for the actuator to travel a full stroke. Verify that the actuator rotates freely throughout the range. Limiting Rotation Range Using M9203-603 Adjustable Stop Kit The actuator is factory set for 95° rotation, and its range is limited in 5° increments to a minimum of 35°. A stroke-limiting stop can be attached in the field to the shaft coupler side of the actuator to reduce the rotation range. Attaching the stroke-limiting stop in the furthest mounting position reduces the rotation range of the actuator by 5°. Each progressive mounting position reduces the rotation range an additional 5°. 1. Check that the damper blade is visible or its position is permanently marked on the end of the damper shaft, as illustrated in Figure 7. FIG:M9203_ Anti-Rotn_Mntg_Brkt_Posn FIG:FIdaG:dmapemrpsos Damper Frame Figure 6: Anti-Rotation Mounting Bracket 2. Bend or cut the anti-rotation bracket to fit the damper frame or duct as illustrated in Figure 6. Note: The anti-rotation bracket can be bent to fit a round damper. 3. Mark or drill mounting holes in the damper frame or duct using the anti-rotation bracket as a guide (based on the measurements obtained in Table 2 and Figure 5). 4. Secure the anti-rotation bracket to the damper frame or duct using the two No. M3.5 x 9.5 mm self-drilling sheet metal screws provided. IMPORTANT: Do not overtighten the mounting screws to avoid stripping the threads. Be certain that the tab on the anti-rotation bracket remains properly positioned in the slot on the actuator, and that the actuator remains parallel to the mounting surface. 5. Slide the actuator onto the damper shaft, and position the anti-rotation bracket tab into the slot at the bottom of the actuator as illustrated in Figure 6. 6. Rotate the damper blade(s) to the desired position if the power is lost. Figure 7: Damper Position 2. Position the stroke-limiting stop in the serrated slot with its leading edge at the scale position matching the desired stroke. 3. The product label marks hole positions for the M3-0.5 x 8 mm self-tapping screw provided with the adjustable stop kit. Drive the screw through the slot in the adjustable stop and into the actuator face over a marked hole position. (See Figure 8.) Note: The minimum rotation range is 35°.
