All actuators in this series provide 27 lb·in (3N·m) rated torque. A mechanical spring return system provides rated torque with or without power applied to the actuator. The series includes the following control options:•On/Off, 24 V, 85 to 264 VAC power•On/Off and Floating Point, 24 V power•Proportional, 24 V power, for 0(2) to 10 VDC or0(4) to 20 mA Control SignalThese actuators are configured for direct mounting and do not require a damper linkage. Actuators can be mounted directly to a damper shaft from 1/4 to 1/2 in. (6to 12 mm) diameter with a universal clamp. An accessory crankarm and remote mounting kit are available for applications where the actuator cannot be direct-coupled to the damper shaft. An optional line voltage auxiliary switch indicates an end-stop position or performs switching functions within the selected rotation range.Table 1: Features and Benefits (Part 1 of 2)FeaturesBenefits27 lb·in (3 N·m) Rated TorqueProvides high torque in a compact package size to expand the range of damper applications in HVAC systems.Direct-Coupled DesignRequires no crankarm or linkage and is capable of direct mounting to a shaft up to1/2 in. (12 mm) diameter and centered on a 1/2 in. (12 mm) shaft.Reversible MountingProvides either clockwise or counterclockwise operation.Electronic Stall DetectionProtects from overload at all angles of rotation. Power consumption is reduced in holding mode. The actuator may be stalled anywhere in its rotation range without the need for mechanical end switches.Double-Insulated ConstructionEliminates need for electrical ground connection for regulatory agency compliance. Microprocessor-controlledBrushless DC Motor(-AGx and -GGx types)Provides constant runtime independent of torque.External Mode Selection Switch(-AGx and -GGx types)Permits control logic reversal for Floating Control (-AGx types). Permits calibration, input signal range selection, and control logic reversal for Proportional Control (-GGx types).Integral Cables with Colored and Numbered ConductorsSimplify installation and field wiring.M9203-xxx-2(Z) Series Electric Spring Return ActuatorsProduct BulletinM9203-AGx-2, M9203-GGx-2, M9203-Bxx-2M9203-AGx-2Z, M9203-GGx-2Z, M9203-Bxx-2ZCode No. LIT-12011674Issued May 2018Figure 1: M9203-xxx-2(Z) Series ElectricSpring Return ActuatorM9203-xxx-2(Z) Series Electric Spring Return Actuators Product Bulletin2Application M9203-GGx-2(Z) Series Proportional ActuatorsM9203-GGx-2(Z) Series Actuators provide proportional modulation of dampers requiring up to 27 lb·in. (3N·m) in HVAC systems that are controlled by an electronic controller or positioner. The actuator responds to 0 to 10 VDC or 2 to 10 VDC control signals. With the addition of a 500 ohm resistor, the actuator responds to a 0 to 20 mA or 4 to 20 mA signal. A 0 to 10 VDC or 2 to 10 VDC feedback signal indicates position and provides support for master-slave applications. Manual control system override applications are supported through field wiring, and include:•override to MIN position•override to MAX position•override to MIN, MID, and MAX positionThe M9203-GGA-2 and M9203-GGA-2Z 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, when used for environmental air handling purposes, is an example of the type of space for which these actuators are configured.The M9203-GGx-2 actuators have 150 second constant runtime for 90° rotation. The M9203-GGx-2Z actuators have 90 second constant runtime for 90° rotation. When combined with other actuators in a control system, this choice provides flexibility in synchronizing the movement of equipment driven from a single proportional command.M9203-AGx-2(Z) Series On/Off and Floating Point ActuatorsM9203-AGx-2Z Series Actuators provide on/off control or modulation of dampers requiring up to 27 lb·in. (3N·m) in HVAC systems. Floating point control is provided from a triac or relay. On/off control can be provided from a manual switch, controller, auxiliary switch from a fan motor contactor, or similar device.Integral 1/2 in. (13 mm) Threaded Conduit Connector(s)Simplify installation and field wiring.Optional Integrated Auxiliary SwitchProvides one integrated, line-voltage-capable Single-Pole, Double-Throw (SPDT) switch with continuously adjustable switch point. Facilitates safety interfacing or signaling.Plenum Rated ModelsEnable use in other environmental air spaces (plenums) in accordance with section 300.22(C) of the National Electric Code.Override Control(Proportional Models Only)Supports manual control system override applications through field wiring.Underwriters Laboratories Inc.® (UL), CE Mark, and C-Tick ComplianceProvides internationally recognized regulatory agency approvals.Manufactured under International Standards Organization (ISO) 9001 Quality Control StandardsEnsures quality.5-Year WarrantyProtects consumer investment.Table 1: Features and Benefits (Part 2 of 2)FeaturesBenefitsIMPORTANT:Use these M9203-xxx-2(Z) Series Electric Spring Return Actuators only to control equipment under normal operating conditions. Where failure or malfunction of the electric 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. Incorporate and maintain other devices, such as supervisory or alarm systems or safety or limit controls, intended to warn of or protect against failure or malfunction of the electric actuator.M9203-xxx-2(Z) Series Electric Spring Return Actuators Product Bulletin3The M9203-AGA-2 and M9203-AGA-2Z 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.

When power fails during service, the mechanical spring return system provides rated torque to the connected equipment, returning it to the home position.M9203-GGx-2(Z) Series Proportional ActuatorsM9203-GGx-2(Z) Series Actuators use a brushless DC motor controlled by a microprocessor. The microprocessor drives the motor at constant speed, independent of torque. The microprocessor also monitors the brushless DC motor’s rotation to prevent damage to the actuator in a stall condition. The actuator can be stalled anywhere within its rotation range without the need for mechanical end switches. Power consumption is reduced in the holding mode.The M9203-GGB-2 and M9203-GGB-2Z models are provided with one integrated, line-voltage-capable auxiliary SPDT switch.
