VA9208-AGx-x Series On/Off and Floating Point Electric Spring Return Valve Actuators

Installation Instructions 1

Refer to the QuickLIT website for the most up-to-date version of this document.

Applications

The VA9208-AGx-x Series On/Off and Floating Point

Electric Spring Return Actuators are direct-mount valve

actuators that operate on AC/DC 24 V power. These

bidirectional actuators are used to provide accurate

positioning on Johnson Controls® VG1000 Series

1-1/4, 1-1/2, and 2 in. (DN32, DN40, and DN50) ball

valves in Heating, Ventilating, and Air Conditioning

(HVAC) applications.

Integral line voltage auxiliary switches, available only

on the VA9208-xxC-3 models, indicate end-stop

position, or perform switching functions within the

selected rotation range.

VA9208-AGA-2 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.

Installation

Install the ball valve with the actuator at or above the

center line of the horizontal piping (see Figure 1).

IMPORTANT: Use this VA9208-AGx-x Series

On/Off and Floating Point Electric Spring Return

Actuator 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.

IMPORTANT : Utiliser ce VA9208-AGx-x Series

On/Off and Floating Point Electric Spring Return

Actuator uniquement pour commander des

équipements dans des conditions normales de

fonctionnement. Lorsqu'une défaillance ou un

dysfonctionnement du electric 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 electric

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: Before specifying VA9208 Series

Electric Spring Return Valve Actuators for plenum

applications, verify acceptance of exposed plastic

materials in plenum areas with the local building

authority. Building codes for plenum requirements

vary by location. Some local building authorities

accept compliance to UL 1995, Heating and Cooling

Equipment, while others use different acceptance

criteria.

IMPORTANT: Do not install or use this VA9208

Series Electric Spring Return 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.

Mounting the Thermal Barrier

Figure 16 shows the optional M9000-561 Thermal

Barrier.

To mount the optional thermal barrier:

1. Install the thermal barrier drive shaft into the

thermal barrier by aligning the tab on the drive

shaft with the slot on the thermal barrier

(Figure 17).

2. Rotate the drive shaft to align marks on the top of

the thermal drive shaft with matching marks on the

valve stem.

3. Mount the thermal barrier onto the valve using the

four included M5x16 mm machine screws and four

M5 flange nuts. Tighten the screws to a

recommended torque of 21 to 25 lb·in.

(2.4 to 2.8 N·m) (Figure 18)

4. Proceed to the actuator mounting instructions.

Follow the same steps as mounting directly to the

valve when mounting actuator to the thermal

barrier.

Note: Depending on your application, you may

position the assembly in any of the four 90° increments

on the valve.

Manual Override

Use only the supplied manual override crank to

reposition the actuator hub when using the manual

override feature.

To reposition the actuator hub, proceed as follows:

1. De-energize the actuator.

2. Insert the hex end of the manual override crank

into the manual override adjustment point on the

face of the actuator.

3. Rotate the manual override crank in the direction

indicated by the arrow on the label.

4. The actuator requires 8-1/2 manual override crank

rotations from the full spring return position to fully

reposition the actuator hub. At the end of travel, the

rotation resistance increases. Do not force the

manual crank past this point.

5. While holding the manual crank in the wound

position, rotate and hold the red lock shaft

approximately 10° then release the manual crank

to lock the actuator hub in place.

Note: Insert and slightly rotate the manual crank

in the direction indicated by the arrow on the label

to unlock the actuator hub. Alternately, the actuator

hub automatically unlocks when power is applied

to the actuator, and returns the actuator to normal

drive and spring return operation.

Wiring

IMPORTANT: Applying excessive torque to the

manual override or operating the manual override

with a power tool may damage the internal

components of the actuator and cause premature

failure.

FIG:in_act

WARNING: Risk of Electric Shock.

Disconnect or isolate all power supplies

before making electrical connections.

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.

Instructions

See Figure 19 to wire the applicable VA9208-AGx-x

Series model.

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.

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.

IMPORTANT: Multiple VA9208-AGx-x Actuators

must be on independent loads.
