Application
The Verasys® Application Controller is part of the SMART Equipment Controller family. The Verasys Application
Controllers run pre-engineered applications and provide the inputs and outputs required to monitor and control a
wide variety of HVAC equipment.
Verasys Application Controllers operate on an RS-485 BACnet® (MS/TP) Bus as BACnet Advanced Application
Controllers (B-AACs) and integrate into Johnson Controls® and third-party BACnet systems.
Verasys Application Controllers have an integral real-time clock. The clock functionality monitors and controls
schedules, calendars, trends, and operate for
the system network.
IMPORTANT: Use this Verasys Application Controller only as an operating control. Where failure or
malfunction of the Verasys Application Controller 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 Verasys Application Controller.

IMPORTANT: Utiliser ce Verasys Application Controller uniquement en tant que dispositif de contrôle de
fonctionnement. Lorsqu'une défaillance ou un dysfonctionnement du controller 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 Verasys Application Controller.

• V e r ify that all parts ship with the controlle r.
• Do not drop the controller or subject it to physical shock.
minimize vibration and shock damage, transport the controller in the original container.
Parts Included
• One Verasys 32 point 24V Application Controller
• One installation instruction sheet
Materials and Special To ols Needed
• Three fasteners appropriate for the mounting surface, such as M4 screws or #8 screws
• One 20 cm (8 in.) or longer piece of 35 mm DIN rail and appropriate hardware for DIN rail moun t only
• Small straight-blade screwdriver for securing wires in the terminal blocks
Mounting
IMPORTANT: Only qualified personnel should install or service Verasys products. These instructions are a
guide for such personnel. Mount the Verasys controllers on a wall or DIN rail inside an enclosure (rated at least
IP20). Carefully follow all instructions in this document and all instructions for the controller.
Follow these guidelines when you mount a field controller:
• Ensure the mounting surface can support the controll er , DIN rail, and any user-supplied enclosure.
• Mount the controller horizontally on 35 mm DIN rail whenever possible.
• Mount the controller in the proper mounting position, see Figure 1.
• Use shi ms or was hers to mount the cont rolle r secur ely and evenly on the mounting surface.
• Mount the controller in an area free of cor rosive va pors a nd fo llow the am bien t conditio n re quireme nts l isted in
Table 11.
• Ensure suffic ien t space around the con troller for
ventilation through the controller. Provide a minimum of 50 mm (2 in.) on the top, bottom, and front of the
controller.

• Do not mount the controller on surfaces prone to vibration, such as duct work.
Horizontal Mount Position
Required for DIN Rail Mounting
• Do not mount the controller in areas where electromagnetic emissions from other devices or wiring can
interfere with controller communication.
Follow these additional guidelines when you mount a field controller in a panel or enclosure:
• Mount the controller so that the enclosure walls do not prevent cover remova l and obstruct ventilation throug h
the controller.
• Mount the controller so that the power tran sfo rmer and other devices do not radiate excessive heat to
controller.
• Do not install the controller in an airtight enclosure.
• Use a zip-tie to secure the controller when you ship it.

DIN Rail Mount Applications
Mounting the field controller horizontally on 35 mm DIN ra il is the preferred mounting method.
To mount a field controller on 35 mm DIN rail, complete the following steps:
the
1. Securely mount a 20 cm (8 in.) or longer section of
space so that the controller mounts as in in Figure 1.
2. Pull the two lower mounting clips outward from the controller to the extended position.
3. Hang the controller on the DIN rail by the hooks at
and position the controller snuggly against the DIN rail.
4. Zip tie the controller to the DIN rail when you ship.
5. Push the bottom mounting clips inward (up) to secure the controller on the DIN rail.
To remove the controller from the DIN rail, pull the bottom mounting clips out to the extended position and
carefully lift the controller off the DIN rail.
IMPORTANT: Do not overtighten the mounting screws. Overtightening the screws may damage the mounting
clips.

Wiring
Risk of Electric Shock.
Disconnect power from the controller before making any adjustments. Do not touch any part of the printed circuit
board while power is applied. Failure to follow these precautions can result in personal injury or death.
Risque de décharge électrique.
Déconnecter l'alimentation du controller avant toute opération de réglage. Veiller à ne toucher aucune partie du
circuit imprimé lorsque celui-ci est sous tension. Le non-respect de ces précautions peut p rovoquer des blessur es
graves, voire mortelles.
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.
Risque de décharge électrique.
Débrancher ou isoler toute alimentation avant de réaliser un branchement électrique. Plusieurs isolations et
débranchements sont peut-être nécessaires pou r -couper entière ment l'alimentation de l'équipement. Tout contact
avec des composants conducteurs de tensions dangereuses risque d'entraîner une décharge électrique et de
provoquer des blessures graves, voire mortelles.
IMPORTANT: Do not exceed the controller electrical ratings. Exceeding controller electrical ratings can result
in permanent damage to the controller and void any warranty.
IMPORTANT: Use copper conductors with a rating of at least 75°C (167°F). Make all wiring in accordan ce with
local, national, and regional regulations.
IMPORTANT: Electrostatic discharge can damage controller components. Use proper electrostatic discharge
precautions during installation, setup, and servicing to avoid damaging the controller.
For detailed information on configuring and wiring an MS/TP Bus, System Bus, and Sensor Bus, refer to the
Verasys® BACnet® MS/TP
Communications Bus T echnical Bulletin (LIT-12012362).
Verasys Appl ication Controller Terminal Blocks and Bus Ports
See Figure 11 for terminal block, spade location, and bus port locations on the LC-VAC300x-0 controller. Use the
following guidelines when wiring a controller.
Input and Output T e rm in al Blocks
On most field controller models, all of the input terminal blocks or spade terminals are mounted on the bottom of the
controller and the output terminal blocks and s p a d e t e r m i n a l s a re mounted on the top of the cont ro l le r. See Table 5
for more information about I/O
terminal functions, requirements, and ratings.

Sensor Bus Port
The Sensor Bus port on the middle left side of the controller (Figure 11) is an RJ-12, 6-position modular jack that
provides a connection for the SBH, the VAV Balancing Too l, specified network sensors, or other Sensor Bus devices
with RJ-12 plugs.
The Sensor port connects internally to the Sensor bus terminal block. See Table 7 for more information . The sen sor
bus port pin assignment is shown in Fi gure 8.
