Description The M91xx Series includes M9108, M9116, M9124, and M9132 models. All of these direct-mount electric actuators operate on AC/DC 24 V power. The M91xx actuators are available for use with on/off, floating, proportional, or resistive controllers. These bidirectional actuators do not require a damper linkage, and are easily installed on a damper with a round shaft up to a 3/4 in. (20 mm) in diameter or a square shaft up to 5/8 in. (16 mm). They may be direct or remote mounted to a damper, or mounted to a valve using one of the M9000-5xx Valve Linkage Kits. A single M91xx model delivers up to 280 lb·in (32 N·m) of torque. Two -AGx, -GGx, or -HGx models in tandem deliver twice the torque or 560 lb·in (64 N·m). The angle of rotation is mechanically adjustable from 0 to 90° in. 5-degree increments. Integral auxiliary switches are available to indicate end-stop position or to perform switching functions at any angle within the selected rotation range. Position feedback is available through switches, a potentiometer, or a DC 0(2) to 10 V signal. Features • simple direct coupling reduces installation and commissioning time while improving reliability by eliminating damper linkages • six torques: 70 to 560 lb·in (8 to 64 N·m) offer the most suitable choice for the application • four control inputs meet the needs of most applications • output position feedback provides simple closed-loop control with accurate position sensing • electronic stall detection ensures higher reliability by deactivating the actuator motor when a stall condition is detected • master/slave operation allows synchronized control for two actuators • stacked for tandem applications • zero and span adjustment (-HGx models) allows sequential operation of dampers from a single input signal of DC 0(2) to 10 V, DC 0(4) to 20 V, or DC 0(4) to 20 mA • jumper-selectable rotation direction and manual gear release simplify installation, setup, and field adjustments • NPT threaded housing provides easy connection for electrical fittings • manual gear release simplifies damper/valve setup and commissioning Applications M91xx actuators are designed to position air dampers and valves in HVAC systems. Applications include: positioning return air or exhaust dampers, controlling face and bypass dampers, positioning blades for variable volume fans, positioning VF4000 and VF5000 Series butterfly valves, and positioning VG1000 Series ball valves and VG7000 Series globe valves when used with the M9000-5xx Series Valve Linkages. Two of the following models provide twice the amount of running torque of a single unit when mounted in tandem: M9116-GGx or -HGx, M9124-AGx, -GGx or -HGx, and M9132-AGx or -GGx. Refer to the manufacturer’s information to properly size the damper, valve, and/or actuator. Spring-return actuators, such as the M9206 and M9216 Series actuators, are recommended for use with outdoor air dampers in cold climates. These compact M91xx actuators use a DC motor with stall detection circuitry that operates throughout the entire stroke. The -GGx, -HGx, and -JGx models employ noise-filtering techniques on the control signal to eliminate repositioning due to line noise. Rotation is mechanically limited to 93° by integral end stops. The position of the actuator is visually indicated from 0 to 90° on the cover. An anti-rotation bracket prevents lateral movement of the actuator. Pressing the spring-loaded gear release on the actuator cover disengages the gear train for manual repositioning of the coupler. Refer to the M9108, M9116, M9124, M9132 Series Electric Non-Spring-Return Actuators Product Bulletin (LIT-2681058) or the M9108, M9116, M9124, M9132 Series Electric Non-Spring-Return Actuators Installation Instructions (Part No. 34-636-399) for important product application information. Repair Information If the M9108, M9116, M9124, or M9132 Series Electric Actuator fails to operate within its specifications, replace the unit.
