Applications
VA9204-Bxx-2 Series on/o󰀨 electric spring return actuators
are direct-mount valve actuators that operate on 24 VAC
power at 50/60 Hz, 24 VDC power, or 85 VAC to 264 VAC
power at 50/60 Hz. These bidirectional actuators are used for
on/o󰀨 control 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-xxB-2 models, indicates end-stop position, or
performs switching functions within the selected rotation
range.
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.
Installation
Install the ball valve with the actuator at or above the center
line of the horizontal piping (see Figure 1).
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

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.

Setup and adjustments
Auxiliary switch (VA9204-xxB-xx models)
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 21).
Figure 21: 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.
The VA9204-xxB-xx models include one integral auxiliary
switch with a switch adjuster accessible on either face
of the actuator (Figure 22). The factory setting for the
auxiliary switch is 10% closing (relative to the 0% to 100%
rotation range as printed on the product label). See the
Technical specications section for the auxiliary switch
ratings.
The switch point is continuously adjustable throughout the
actuator’s rotation range. For the most accurate switch
positioning, see Figure 22 and use the method in the following
example. To change the switch point of the auxiliary switch:
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 Step 1 through
Step 3.
