VA-6100 Series Electric Valve Actuators Installation Instructions1ApplicationsVA-6100 Series Electric Valve Actuators use a synchronous motor to accurately position JohnsonControls® VG2000 Series Cast Iron Flanged Globe Valves in Heating, Ventilating, and Air Conditioning (HVAC) and industrial applications. These non-spring return electric actuators provide a 1,350 lb (6,000 N) force output for on/off (floating) or proportional control. Integral auxiliary switches are available for indicating end stop position, or for performing switching functions. Position feedback is also available through an isolated 2,000 ohm potentiometer at a fixed stroke of 1-21/32 in., or a nominal 0 to 10 VDC feedback signal. All models feature a hand wheel for manual positioning of the valve, independent of a power supply.InstallationNote the pre-installation details described in this section. Before installing a VA-6100 Series Electric Valve Actuator onto a VG2000 Series Cast Iron Flanged Globe Valve:•install the actuator and valve assembly with the actuator at or above the centerline•mount the actuator and valve assembly in an upright position, in a conveniently accessible location. When mounting the assembly horizontally, orient the yoke so that the yoke supports are positioned vertically, one above the other (as illustrated in Figure1). •allow sufficient clearance to remove the actuator (as illustrated in Figure4)IMPORTANT:Use this VA-6100 Series Electric Valve 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. 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 actuator.IMPORTANT:Utiliser ce VA-6100 Series Electric Valve Actuator uniquement pour commander des équipements dans des conditions normales de fonctionnement. Lorsqu'une défaillance ou un dysfonctionnement du actuator risque 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 actuator.IMPORTANT:Mount the actuator within 90 of the vertical position above the valve body. Failure to do so may permit water or moisture to travel down the valve stem, damaging the actuator and voiding the warranty.IMPORTANT:Protect the actuator from dripping water, condensation, and other moisture. Water or moisture could result in an electrical short, which may affect the operation of the actuator.IMPORTANT:Do not cover the actuator with thermal insulating material. High ambient temperatures may damage the actuator, and a hot water pipe, steam pipe, or other heat source may overheat it.Figure 1: Proper Yoke OrientationO.K.O.K.FIG:yokeVA-6100 Series Electric Valve ActuatorsInstallation InstructionsVA-6100-xxxPart No. 14-1234-18, Rev.

This debris can damage or severely impede the operation of the valve by embedding itself in the seats, scoring the valve, and ultimately resulting in seat leakage. If the debris becomes embedded in the seats, subsequent flushing and filtering of the piping system with the valve installed does not remedy the problem.Figure 2: VA-6100-HGC Circuit Board Parts and Light-Emitting Diode (LED) IdentificationMP 3Action Switch(0 = Direct Acting; 1 = Reverse Acting)Shown in Reverse Acting Mode;52 53 51Terminal BlockF2A/24VMP 2MP 1MP 5MP 6MP 4FIG:cboardTerminalBlock55 5460 61 58 57 56 59Terminal Block1234Green LED, V18(Ingoing Actuator StemOperation, OPEN)Yellow LED, V19(Outgoing Actuator StemOperation, CLOSED)Red LED, V21(Dead Time Active)Red LED, V22(E1 < 4mA)P1P2P4X1VA-6100 Series Electric Valve Actuators Installation Instructions3Special Tools NeededTransfer Bolt SettingPrior to applying power to the VA-6100-HGC Electric Valve Actuator, check that the transfer bolt is set at the proper stroke length for the valve size as indicated in Table2.See Figure3 to locate the stroke length identification sticker to determine the transfer bolt setting and associated stroke length.Figure 3: Cam and Feedback Potentiometer IdentificationTerminal BlockAuxiliarySwitchesStroke LengthIdentification Sticker(Measurements in mm)CamKnurledCam LockingKnobTransferArmCamCapacitor(The transfer boltis located behind thecapacitor.)FeedbackPotentiometerFIG:camfeedTable 1: Special Tools NeededActuator/Valve PartRecommended Actuator Mounting ToolsPacking Nut1 in.

The ohmmeter should display a resistance of less than 10 ohms.3.Apply 24 VAC power to Terminals 1 and 3 (Figure6) to drive the valve stem fully up. The ohmmeter should display a resistance of 1,300 to 1,500 ohms for a 4 in. valve; 1,600 to 1,800 ohms for a 5 in. valve; and 1,700 to 1,900 ohms for a 6 in. valve.To adjust the auxiliary switches, proceed as follows:1.Use Figure3 to locate the auxiliary switches, cams, and terminal block.2.Loosen the knurled cam locking knob by turning it counterclockwise.3.Adjust the actuator to the desired down position where the inner auxiliary switch is to be tripped.4.Adjust the inner cam so that it just trips the inner auxiliary switch.5.Adjust the actuator to the desired up position where the outer auxiliary switch is to be tripped.6.Adjust the outer cam so that it just trips the outer auxiliary switch.7.Tighten the knurled cam locking knob by turning it clockwise.To use the manual hand wheel to control the valve, proceed as follows:1.Disconnect the power.2.Pull down on the T-clutch. The T-clutch is located below the manual hand wheel.3.Rotate the manual hand wheel clockwise to extend the actuator stem and lower the valve stem. Rotate the manual hand wheel counterclockwise to retract the actuator stem and raise the valve stem.VA-6100-HGC Electric Valve ActuatorThe actuator action for the VA-6100-HGC Electric Valve Actuator is as follows:Direct Acting: As the control signal increases, the actuator stem fully extends and the valve stem moves to the fully down position. With no control signal, the actuator moves to the fully retracted position.Reverse Acting: As the control signal increases, the actuator stem retracts and the valve stem moves to the fully up position. With no control signal, the actuator moves to the fully extended position.To switch from direct acting to reverse acting or vice versa, proceed as follows:1.Apply 24 VAC power to Terminals 54 and 55 (Figure7) and determine if the actuator is set for direct acting or reverse acting.2.Disconnect the 24 VAC power if the actuator is not set for the desired action. Skip Step3 and Step4 if the actuator is set for the desired action.3.Set the action switch on the actuator circuit board from the 0(direct acting) position to the 1(reverse acting) position (Figure2).4.Apply 24 VAC power to Terminals 54 and 55 (Figure7) and check for the desired action.To adjust the operating range of the VA-6100-HGC Electric Valve Actuator, see Figure2 and proceed as follows:1.Apply 24 VAC power to Terminals 54 and 55 (Figure7).2.Note the location of the green and red LEDs on either end of the terminal block (Figure2). The green LED illuminates when the actuator motor is running, and the red LED illuminates when the actuator motor is stopped.3.For direct action, proceed as follows:a.Input the desired minimum control signal between 0 and 8 VDC to Terminals 56 and 57 (Figure7) for voltage applications, or input the desired minimum control signal between 0 and 16 mA to Terminals 58 and 59 (Figure7) for current applications. The actuator motor may run, illuminating the green LED (see Figure2). If so, wait until the actuator motor stops and the red LED is illuminated before proceeding.IMPORTANT:Do not power VA-6100 Series Electric Valve Actuators using the JohnsonControls M9000-200 Commissioning Tool. The M9000-200 provides a maximum power of 25 VA. The VA-6100-AGC Electric Valve Actuator requires 37VA and the VA-6100-HGC requires 42 VA. If the M9000-200 is used to power either valve actuator, the commissioning tool could become damaged.Note: As of October 2017 the M9000-200 has been discontinued.VA-6100 Series Electric Valve Actuators Installation Instructions8b.Connect a voltmeter to Terminals 57 and 61 or a current meter to Terminals 58 and 60 (Figure7). The voltmeter should be on the 10V range or the current meter should be on the 20 mA range.c.Rotate the feedback potentiometer clockwise to its stop (Figure3).d.Locate Potentiometer P1 on the actuator circuit board (Figure2) and adjust it until the voltmeter reads 0.35 V above the minimum control signal or the current meter reads 0.7mA above the minimum control signal. The actuator should fully retract.e.Check that the feedback potentiometer is fully clockwise and readjust it, if necessary. The motor may operate when the feedback potentiometer is adjusted. After the motor stops, readjust Potentiometer P1 until the voltmeter reads 0.35 V above the minimum control signal or the current meter reads 0.7mA above the minimum control signal.f.Input the desired maximum control signal between 2 and 10 VDC to Terminals 56 and 57 (Figure7) for voltage applications, or input the desired maximum control signal between 4 and 20 mA to Terminals 58 and 59 (Figure7) for current applications. The maximum control signal must always exceed the minimum control signal by at least 2 VDC or 4 mA.g.Locate Potentiometer P2 on the actuator circuit board (as illustrated in Figure2) and adjust it until the voltmeter reads 0.35 V below the maximum control signal or the current meter reads 0.7 mA below the maximum control signal. The actuator should fully extend.Note:If Potentiometer P2 adjustment is insufficient, adjust the transfer bolt. The transfer bolt is located behind the capacitor (Figure3). For reference purposes, a scale with numbers that correspond to notches on the transfer lever is located on the surface just below the feedback potentiometer.Loosening the transfer bolt nut and moving the transfer bolt location changes the span of the actuator operating range. If the voltage span from Step3, Stepc through Stepg is insufficient, the center of the transfer bolt needs to be adjusted to a smaller number (as indicated on the scale). If the voltage span is too great, the center of the transfer bolt needs to be adjusted to a larger number (as indicated on the scale). Regardless of which way the transfer bolt is moved, direct action Stepc through Stepg must be repeated.4.For reverse action, proceed as follows:a.Input the desired maximum control signal between 2 and 10 VDC to Terminals 56 and 57 (Figure7) for voltage applications, or input the desired maximum control signal between 4 and 20 mA to Terminals 58 and 59 (Figure7) for current applications.
