Applications

VA9204-GGx-2Z Series proportional electric spring return

actuators are direct-mount valve actuators that operate on

24 VAC/VDC power. These bidirectional actuators are used to

provide accurate positioning on Johnson Controls® VG1000

Series 1/2 in., 3/4 in., and 1 in. (DN15, DN20, and DN25) ball

valves in HVAC applications.

An integral line voltage auxiliary switch, available only on

the VA9204-GGB-2Z model, indicates end-stop position,

or performs switching functions within the selected rotation

range.

VA9204-GGA-2Z actuators include plenum-rated cables and

are specially congured for installation in spaces used for

environmental air-handling purposes other than ducts and

plenums as specied in National Fire Protection Association

(NFPA) 70: National Electrical Code (NEC) 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

congured.

IMPORTANT: Use this VA9204 Series valve actuator only

to control equipment under normal operating conditions.

Where failure or malfunction of the VA9204 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 VA9204 Series valve actuator.

IMPORTANT : Utiliser ce VA9204 Series valve actuator

uniquement pour commander des équipements dans

des conditions normales de fonctionnement. Lorsqu’une

défaillance ou un dysfonctionnement du VA9204 Series

valve 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 VA9204 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.

Figure 1: Mounting positions for chilled water and

condensing atmosphere applications

IMPORTANT: Do not install or use this VA9204 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.

Special tools needed

• Digital voltmeter

• T-20 TORX® driver

Installation

Install the ball valve with the actuator at or above the center

line of the horizontal piping (see Figure 1).

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.

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 vérié tous les raccords de câblage.

Des ls 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 l non utilisé avant de

mettre l’actuator sous tension. Le non-respect

de cette obligation d’isolation et de protection de

chaque l 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.

Using conduit

All VA9204 Series actuators accept 1/2 in. threaded

electrician’s ttings (Figure 22).

Figure 22: Adding exible metal conduit

1. Feed the actuator cables through the eld-supplied

electrician’s tting and conduit.

2. Thread the electrician’s tting into the actuator and secure

the conduit to the tting in accordance with local building

code requirements.

Setup and adjustments

Mode selection switch

Actuators have an external mode selection switch to calibrate,

select the input signal range, and to reverse the control logic.

The switch is accessible from both the A and B sides of the

actuator (Figure 23). Actuators are delivered in Direct Acting

(DA), 0 VDC to 10 VDC input signal mode. To change to

Reverse Acting (RA) mode, move the mode selection switch

from DA to RA. The input signal range is selectable between

0 VDC to 10 VDC or 2 VDC to 10 VDC. If you do not use

the CAL function, both input signal ranges are proportioned

across the full rotation range of 0° to 95° rotation.

For example, if you select a 0 VDC to 10 VDC input signal

and the rotation range is limited to 75°, the rotation range lit

will be reached at 8.3 VDC.

CAL

Control response

The installation side of the actuator and the position of the

mode selection switch combine to determine control response

from the actuator (Figure 24).

Figure 24: Control response

Calibration (CAL) function

The CAL function enables the actuator to redene the

selected input signal range proportionally across a reduced

rotation range. The actuator maintains calibration when power

is lost or removed.

Follow these steps to calibrate the input signal range:

1. With power applied to the actuator, move the mode

selection switch to the CAL position and leave it in this

position for approximately 5 seconds. The actuator begins

rotating until the end-stops are found.

2. Move the mode selection switch to the desired input signal

range. You can make a selection while the calibration

process is in progress, or after it is complete. The selected

input signal is proportionally recongured to the reduced

rotation range.

Note: During normal operation, if the actuator stroke

increases due to seal or seat wear, input signals are

automatically recongured to the increased rotation range in

approximately 0.5° increments.

3. If the actuator mounting position is changed or if the

linkage is adjusted, repeat Step 1 and Step 2 to repeat the

CAL function.

Note: The mode selection switch must remain out of the CAL

position for at least 2 seconds before re-initiating the CAL

function.

Note: If the mode selection switch is left in the CAL position,

the actuator defaults to 0 V to 10 V input signal range, DA.
