VA9203-Bxx-2 Series On/Off Electric Spring Return Valve Actuators InstallationInstructions1 Refer to the QuickLIT website for the most up-to-date version of this document.ApplicationsThe VA9203-Bxx-2 Series On/Off Electric Spring Return Actuators are direct-mount valve actuators that operate on AC 24 V power at 50/60 Hz, DC 24 V power, or AC 85 to 264 V power at 50/60 Hz. These bidirectional actuators are used for on/off control on JohnsonControls® VG1000 Series 1/2, 3/4, and 1 in. (DN15, DN20, and DN25) ball valves in Heating, Ventilating, and Air Conditioning (HVAC) applications.An integral line voltage auxiliary switch, available only on the VA9203-xxB-2 models, indicates end-stop position, or performs switching functions within the selected rotation range. InstallationInstall the ball valve with the actuator at or above the center line of the horizontal piping (see Figure1). Special Tool Needed•Digital voltmeter•T-20 TORX® driverIMPORTANT:Use this VA9203 Series Valve Actuator only to control equipment under normal operating conditions. Where failure or malfunction of the VA9203 Series Valve 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 VA9203 Series Valve Actuator.IMPORTANT :Utiliser ce VA9203 Series Valve Actuator uniquement pour commander des équipements dans des conditions normales de fonctionnement. Lorsqu'une défaillance ou un dysfonctionnement duVA9203 Series Valve Actuatorrisque de provoquer des blessures ou d'endommager l'équipement contrôlé ou un autre équipement, la conception du système de contrôle doit intégrer des dispositifs de protection supplémentaires. Veiller dans ce cas à intégrer de façon permanente d'autres dispositifs, tels que des systèmes de supervision ou d'alarme, ou des dispositifs de sécurité ou de limitation, ayant une fonction d'avertissement ou de protection en cas de défaillance ou de dysfonctionnement du VA9203 Series Valve Actuator.IMPORTANT:In steam applications, install the valve with the stem horizontal to the piping. Failure to follow this precaution may shorten the life of the actuator.IMPORTANT:Do not install or use this VA9203 Series Valve Actuator in or near environments where corrosive substances or vapors could be present. Exposure of the actuator to corrosive environments may damage the device’s internal components, and will void the warranty.Figure 1: Mounting Positions for Chilled Water and Condensing Atmosphere FIG:mntpos_H2O_appVA9203-Bxx-2 Series On/Off Electric Spring ReturnValve ActuatorsInstallation InstructionsVA9203-BGA-2, VA9203-BGB-2,VA9203-BUA-2, VA9203-BUB-2Part No. 14-1380-16, Rev.

More than one disconnection or isolation may be required to completely de-energize equipment. Contact with components carrying hazardous voltage can cause electric shock and may result in severe personal injury or death.AVERTISSEMENT : Risque de décharge électrique.Débrancher ou isoler toute alimentation avant de réaliser un raccordement électrique. Plusieurs isolations et débranchements sont peut-être nécessaires pour -couper entièrement l'alimentation de l'équipement. Tout contact avec des composants porteurs de tensions dangereuses risque d'entraîner une décharge électrique et de provoquer des blessures graves, voire mortelles.!CAUTION: Risk of Property Damage.Do not apply power to the system before checking all wiring connections. Short circuited or improperly connected wires may result in permanent damage to the equipment.MISE EN GARDE : Risque de dégâts matériels.Ne pas mettre le système sous tension avant d'avoir vérifié tous les raccords de câblage. Des fils formant un court-circuit ou connectés de façon incorrecte risquent d'endommager irrémédiablement l'équipement.VA9203-Bxx-2 Series On/Off Electric Spring Return Valve Actuators Installation Instructions9Using ConduitAll VA9203 Series Actuators accept 1/2in. threaded electrician’s fittings (Figure21).1.Feed the actuator cables through the field-supplied electrician’s fitting and conduit.2.Thread the electrician’s fitting into the actuator and secure the conduit to the fitting in accordance with local building code requirements.Setup and AdjustmentsAuxiliary Switch (VA9203-xxB-xx Models) The VA9203-xxB-xx models include one integral auxiliary switch with a switch adjuster accessible on either face of the actuator (Figure22). The factory setting for Auxiliary Switch is 10% closing (relative to the 0 to 100% rotation range as printed on the product label). See the Technical Specifications section for the auxiliary switch ratings.The switch point is continuously adjustable throughout the actuators’s rotation range. For the most accurate switch positioning, see Figure22 and use the method in the following example. To change the switch point of auxiliary switch, proceed as follows:1.Position the actuator in the full spring return position.Note:The switch is factory set to trip when the actuator reaches the 10% position.2.Rotate the switch adjuster until it points to the desired switch point.3.Connect the auxiliary switch to a power source or an ohmmeter and apply power to the actuator. The actuator moves to the fully open position and holds while power is applied.4.Observe the switch point. If required, repeat Step1 through Step3.Repair InformationA number of replacement parts are available; see Table4 for more details. If an VA9203 Series Electric Actuator fails to operate within its specifications, replace the unit. For a replacement electric actuator, contact the nearest JohnsonControls representative.!CAUTION: Risk of Property Damage.Insulate and secure each unused wire lead before applying power to the actuator. Failure to insulate and secure each unused wire lead may result in property damage.MISE EN GARDE : Risque de dégâts matériels.Isoler et protéger chaque fil non utilisé avant de mettre l'actuator sous tension. Le non-respect de cette obligation d'isolation et de protection de chaque fil non utilisé risque d'entraîner des dégâts matériels.IMPORTANT:Make all wiring connections in accordance with the National Electrical Code and local regulations. Use proper Electrostatic Discharge (ESD) precautions during installation and servicing to avoid damaging the electronic circuits of the actuator.Figure 21: Adding Flexible Metal Conduit!WARNING: Risk of Electric Shock and Property Damage.Insulate and secure each unused wire lead before applying power to the actuator. Failure to insulate and secure each unused wire lead may result in property damage, electric shock, and severe personal injury or death.AVERTISSEMENT : Risque de décharge électrique et dégâts matériels.Isoler et protéger chaque fil non utilisé avant de mettre l'actuator sous tension.
