Caution and Safety

ATTENTION: Safety. READ THE ENTIRE MANUAL BEFORE OPERATING THE FAN. Ensure that

all safety practices and instructions are followed during the installation, operation and servicing

of the fan. Failure to apply these safety practices could result in death or serious injury. If you do

not understand the instructions, please call our Technical Department for guidance.

ATTENTION: Qualified Technicians. All fan controls and incoming power should only be

installed by qualified technicians familiar with the requirements of the National Electrical Code

(NEC) and local codes. Refer to appropriate portions of this manual for other important

ATTENTION: Code Compliance. Installation is to be in accordance with the NEC, ANDSI/NFPA

70-1999 and local codes.

Hazard of Electrical Shock, Explosion or Arc Flash:

ATTENTION: Read. Read and understand this manual before installing or operating a fan unit.

Installation, adjustment, repair, and maintenance must be performed by qualified personnel.

ATTENTION: Code Compliance. The user is responsible for compliance with all international

and National Electrical Code requirements with respect to grounding of all equipment.

WARNING: Do Not Touch. Many of the parts of this unit operate at line voltage. DO NOT

TOUCH.

WARNING: Covers. Install all covers before applying power or starting and stopping the unit.

Installation and Service

WARNING: Damage. Do not operate or install any fans or fan accessories that appear to be

damaged.

WARNING: Death and Injury. Failure to follow this instruction can result in death, serious

injury, or equipment damage.

WARNING: Disconnect Power. If the fan does not operate properly using the procedures in

this manual. BE CERTAIN TO REMOVE ALL POWER TO THE UNIT and contact our technical

department for further assistance.

CAUTION: Moving Parts. Keep all body parts clear of moving parts at all times.

ATTENTION: Qualified Technicians. All electrical troubleshooting and repair must be done by

a qualified technician and meet all applicable codes.

REFER TO FAN INSTALLATION MANUAL(S) FOR FURTHER MAINTENANCE INFORMATION.

Fan Network Ordering

It is important to purchase fans that are setup for a network. MacroAir customizes fans to

operate in a network by:

Addressing the fans.

Providing bean crimps for T-splices (AVD 370).

Supplying an additional 15ft [4.57m] piece of CAT5e (AVD 370).

Modifying the panel enclosure (AVD3, 550, 780, Y and X Series Fans).

Modifying the wiring on the VFD (AVD3, 550, 780, Y and X Series Fans).

Note: If you did not order your fans for a network, please contact Technical Support for

assistance with networking your fans. Also, when installing new fans in an existing mixed

network, contact Technical Support.

Note: For 370 Fans, Repeaters/Isolators must be added every 5 fans for stability. (Page 6)

*If you did not order your fans for a network by default, they will all have a default Node

Address, and you will be missing necessary materials. Contact technical support to modify your

fans when installing for networking.

Modbus/BACnet Nomenclature

ATTENTION: For purposes of this manual the following shall be true:

It shall be recognized that where this manual indicates BACnet it shall be recognized as

Modbus/BACnet .

It shall be recognized that where this manual indicates BACnet IP it shall also be

recognized as Modbus TCP/IP .

It shall be recognized that where this manual indicates BACnet MSTP it shall also be

recognized as Modbus RTU .

Repeater Install for AVD 370 Fans

Repeater/Isolator

The Repeater/Isolator boosts the sign

minimizes noise on the line.

Repeaters/Isolators should be evenly placed in the network. Make sure there is at least one

Repeater/Isolator every 5 fans.

Network Wiring Requirements

Use Stranded Twisted Pair, CAT5e (or higher grade) shielded cable

Minimum 24 AWG (0.5mm) cross section

Route wires as far away as possible from high voltage AC cables, fluorescent lights, arc

welders, and other equipment that transmits EMI (electromagnetic interference).

For AVD 370 Fans:

Ground the shielding and drain wire at only one point of the cable run

Add Repeaters/Isolators (1/5fans)

Daisy Chain

Networked MacroAir fans must be connected in one single line, referred to in this document as a

The characteristics of a proper daisy chain are: one beginning (AirLynk) and one

end (last fan).

If the fans are not connected in one line/chain, there will be a de-graduation of the

communication signal and the network may not function as intended (fans in the network may

not operate).

Excess Cable at Connection Point

With noise being emitted throughout a typical industrial/commercial environment, extra cable

should not be coiled up as the coil itself will create noise/interference in the communication

signal. There should be no more than two feet of excess cable at each connection point.

If more than two feet of cable is needed for future relocation of the fan, run the cable up toward

the ceiling and back down in a horseshoe shape.

ALWAYS AVOID SHARP BENDS OF THE CABLE.

A Quick Start Guide

PLC STARTUP

Basic navigation around the PLC display

1. Use the up , down , left , and right

arrows to navigate through the options on the screen.

2. Press OK to select the currently highlighted option

(takes you to another screen or allows you to edit the

selected value).

3. If the option is editable you will then be able to edit it using the up and down arrows. To

get to the next digit press the left or right arrows. When you are done editing, press OK

to set the value.

NOTE: The fans will be auto discovered each time the PLC is powered on. Setting the fans

through the web browser will ensure that the PLC knows there is a fan at that address.
