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.

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.
