Greenheck AMD TD Series User manual

This manual is the property of the owner and is required for future maintenance. Please leave it with the owner when
the job is complete.
Receiving and Handling
Upon receiving dampers, check for both obvious
and hidden damage. If damage is found, record all
necessary information on the bill of lading and file
a claim with the final carrier. Check to be sure that
all parts of the shipment, including accessories, are
accounted for.
Dampers must be kept dry and clean. Indoor storage
and protection from dirt, dust, and the weather is
ideal. Do not store at temperatures in excess of
100°F (37°C).

AMD-xx-TD Series
Installation, Operation and Maintenance Manual
Please read and save these instructions for future reference. Read carefully before attempting to assemble, install,
operate or maintain the product described. Protect yourself and others by observing all safety information. Failure
to comply with these instructions will result in voiding of the product warranty and may result in personal injury
and/or property damage.

Pre-Installation Guidelines
The basic intent of a proper installation is to secure
the AMD-xx-TD series damper into the opening in
such a manner as to prevent distortion and disruption
of damper operation. The following items will aid in
completing the damper installation in a timely and
effective manner.
1. Check your schedule for proper damper locations
within the building. Visually inspect the damper for
damage.
2. When you lift or handle the damper use the sleeve
or frame. Do not lift damper using blades, linkage,
actuators, probes, or jackshafting. When you handle
multiple section assemblies, use sufficient support
to evenly lift at each section mullion (see drawing).
Do not drag, step on, apply excessive bending,
twisting, or racking.
3. Do not install screws in damper frame that will
interfere with unexposed blade linkage and prevent
damper blades from opening and/or closing.
4. Damper must be installed into duct or opening
square and free of twist or other misalignment.
Damper must not be squeezed or stretched into
duct or opening. Out of square, racked, twisted
or misaligned installations can cause excessive
leakage and/or torque requirements to exceed
damper/actuator design.
5. Damper, actuator, and transmitter must be kept
clean, dry and protected from dirt, dust and other
foreign materials prior to and after installation.
Examples of such foreign materials include but are
not limited to:
a) Mortar dust
b) Drywall dust
c) Firesafing materials
d) Wall texture
e) Paint overspray
Spreader Bar
Attachments
Multi section dampers
6. Damper should be sufficiently covered as to prevent
overspray if wall texturing or spray painting will
be performed within 5 feet (1.5m) of the damper.
Excessive dirt or foreign material deposits on the
damper can cause excessive leakage and/or torque
requirements and inaccurate airflow measurement to
exceed damper/actuator design.
7. ACCESS: Suitable access (actuators maintenance,
etc.) must be provided for damper inspection
and servicing. Where it is not possible to achieve
sufficient size access, it will be necessary to install a
removable section of duct.
Electrical Guidelines
All wiring shall be done in accordance with the National
Electrical Code ANSI/NFPA-70 latest edition, any local
codes that may apply, and wiring diagrams developed
in compliance with the job or project design and
specifications.
Important!
Electrical in put may be needed for this equipment. This
work should be performed by a qualified electrician.
Verify power before wiring actuator. Greenheck is not
responsible for any damage to, or failure of the unit
caused by incorrect field wiring. To avoid causing death
or serious bodily harm to building occupants, follow all
instructions carefully. Dampers must close completely to
preserve the integrity of the fire smoke separation.
Connect electrical connection to power strip as shown
in drawings on pages 4 and 5.
AMD-xx-TD Series2

6.AMD-xx-TD series more than one section high will be
shipped separately in individual sleeves. Using the provided
RJ-45 cable connect the bottom probe on the top section to
the top probe on the bottom section. The bottom section has
the transmitter mounted to it.
Do not twist
or bow. Mount
damper plumb
in the opening.

Installation - Failure to follow instructions will
void all warranties
1. Ensure the AMD-XX-TD series dampers is mounted
with measurement probes upstream of the damper.
2. Your duct opening or opening square should measure
1/4 inch (6mm) larger than damper dimension and
should be straight and level.
3. Use shims between damper frame and duct opening
or opening space to prevent distortion of frame by
fasteners holding it in place. Brace at every horizontal
mullion and vertically brace at every 8 feet (2.4m) of
damper width for strength. Dampers in high velocity
(2000 fpm [610m per second]) may require more
bracing.
NOTE: Greenheck dampers are specifically designed
and engineered for structural integrity based on model
and conditions. Attachment, framing, mating flanges,
and anchoring of damper assemblies into openings,
ductwork, or walls is the responsibility of the installer.
Design calculations for these retaining and supporting
members should be determined by field engineers for
that particular installation.
4.Individual damper sections, as well as entire multiple
section assemblies must be completely square and
free from racking, twisting, or bending. Measure
diagonally from upper corners to opposite lower
corners of each section.
5.Damper blades, axles, and linkage must operate
without binding. Before system operation, you can
cycle dampers after installation to assure proper
operation. On multiple section assemblies all sections
should open and close simultaneously.
Setup and Operation for AMD-xx-TD
Series Damper
All AMD-xx-TD’s are supplied with a Vari-Green®
airflow rate transmitter that is factory wired to one or
more Vari-Green airflow measurement probe(s). The
transmitter has been configured at the factory with
customer supplied parameters. For normal applications
the transmitter’s configuration should not need to be
modified in the field. However, if field configuration is
necessary please reference the Vari-Green transmitter
Installation, Operation, and Maintenance Manual
available at www.greenheck.com.
Once electrical power is applied, the transmitter will
go through a standard start-up sequence during which
it will identify and enable each airflow sensor. This will
take approximately 25 seconds. Once the start-up
sequence has been complete, the transmitter’s display
will show the measured volumetric airflow rate, velocity,
and ambient air temperature (see below). Under normal
operation, a blinking green dot in the upper right corner
of the display signifies that the processor is functioning
correctly, and two flashing arrows indicate that the
sensor(s) and transmitter are communicating normally.
You can order AMD-xx-TD’s with or without a factory
supplied controller. When a factory supplied controller
is ordered, the controller can be configured for either
analog operation or operation via a BACnet MS/TP
connection. Setup and operation for these different
options are described on the following pages.
AMD-xx-TD Series 3

AMD-xx-TD Series Damper Without a
Factory Supplied Controller
Units ordered without a factory supplied controller are
supplied with a standard modulating actuator. The Vari-
Green transmitter and actuator are wired to a factory
supplied terminal block. Figure 1 shows the field wiring
side of the terminal block.
The 0-10 VDC analog output at terminals 3 and 4 comes
from the Vari-Green transmitter and is proportional
to the velocity going through the AMD-xx-TD. A 10
VDC signal represents the maximum velocity that was
selected at the time the unit was ordered. The selected
maximum velocity and the area of the AMD-xx-TD
are listed on a label adjacent to the terminal block. An
example of how you can determine the velocity and/or
cfm going through the unit is shown below.

AMD-xx-TD Series Ordered with a
Factory Supplied Controller
When you order a factory supplied controller, it comes
with a Greenheck exclusive VAF24-BAC-GTD actuator
which has the controller integrate inside of it. The
actuator/controller is configured by the factory at the
time the unit was ordered for either analog or BACnet
operation. This selection is made by setting the Setpoint
Source datapoint to Local AI or BACnet. A complete list
of all the BACnet datapoints is listed in Table 1 (page 7).

Example 1:
Determine the CFM from a 24 in. x 24 in. AMD-xx-TD
(area of 4 ft2) with a selected maximum velocity of 2,000
fpm and a voltage reading across terminals 3 and 4 of
3.5 VDC.
AMD-xx-TD Series4

The controller is designed to modulate the AMD-xx-
TD series damper such that it maintains a desired
cfm setpoint. The setpoint is supplied via a 0-10 VDC
analog input (terminals 5 and 6) that is proportional to
that setpoint. The Vari-Green transmitter will output
a 0-10 VDC signal (terminals 3 and 4) proportional to
the actual cfm being measured by the unit. For both
the desired cfm setpoint and the cfm output, a voltage
reading of 10 VDC represents the maximum velocity
that was selected at the time the product was ordered.
The selected maximum velocity and the area of the
AMD-xx-TD are listed on a label adjacent to the terminal
block. Example 2 shows how to determine the voltage
corresponding to the desired cfm setpoint.
Example 2:
Determine the voltage setpoint that should be sent to
terminals 5 & 6 to achieve a flow of 4,800 CFM on a 24
in. x 24 in. AMD-xx-TD (area of 4 ft2) with a selected
maximum velocity of 2,000 fpm.
Maximum CFM = 4 ft2* 2,000 fpm = 8,000 cfm
Voltage Setpoint = 10 * (Desired CFM Setpoint /
Maximum CFM)
Voltage Setpoint = 10 *(4,800 / 8,000) = 6.0 VDC
See example 1 on how to convert the transmitter
voltage output (terminals 3 & 4) to cfm.

Figure 3
This controller is designed to modulate the AMD-xx-
TD series damper such that it maintains a desired
cfm setpoint. The setpoint is established by the
BACnetSetpoint datapoint. Table 1 lists all of the BACnet
datapoints. The BACnet Setpoint is a percentage of the
MaxCFMSetpoint datapoint, which is set at the factory
based on the maximum velocity which is selected at the
time the unit is ordered.
Example 3: Determine the BACnet setpoint for a 24
in. x 24 in. AMD with a maximum velocity of 2,000 fpm
and a target flow of 6,000 cfm.
MaxCFMSetpoint = 8,000 cfm (4 ft2 x 2,000 fpm)
BACnet Setpoint = (Target CFM / Maximum CFM)
BACnet Setpoint = (6,000 / 8,000) = 75%
With a BACnet Setpoint of 75% the actuator/controller
will position the damper to allow 6,000 cfm through it.
Position Control Mode
Example 3 applies when the actuator/controller is
in its factory default operating mode called “Flow
Control Mode”. However, for certain applications it may
be desirable to operate the AMD-TD as a standard
modulating damper. This can be accomplished by
changing the DamperMode BACnet data point (see
Table 1) from CurrentAirflow to DamperPosition. In
“Position Control Mode” a BACnet Setpoint of 75% will
drive the damper 75% open instead of finding a position
that supplies 75% of the maximum airflow.
Safety Override of the BACnet Setpoint
If your application requires the ability to locally close
the damper, the factory installed jumper wire should be
removed and replaced with a normally closed “safety
switch”. When the safety switch is closed the damper
will track the BACnet Setpoint as if the jumper wire was
left in place. When the safety switch is open the actuator
will power the damper closed. Interlocking the damper
with a fan such that the damper closes when the fan
shuts down is an example of when the safety switch
feature may be utilized.

AirflowSetpoint AI 2 C Displays the real-time setpoint in cfm
CurrentAirflow AI 3 C Displays the real-time volumetric airflow rate in cfm
AirVelocity AI 4 C Displays the real-time air velocity in fpm
DamperPosition AI 5 C Displays the real-time damper position as a percentage (0% - fully
closed; 100% fully open)
MaxCFMSetpoint AI 6 C
Displays the maximum volumetric airflow rate in cfm. This value is
a function of the value selected for "Maximum FPM". (Max CFM
Setpoint = Damper Area * Maximum FPM).
DamperArea AV 1 C Represents the nominal damper face area in square feet. Set by
the factory.
MinimumFPMSetpoint AV 2 C
Represents the minimum allowable velocity setpoint in fpm. If the
actuator receives a setpoint below the "Minimum FPM Setpoint"
the setpoint will be set to zero. The factory default value is 100
fpm.
BACnet Setpoint AV 3 C
When the Setpoint Source is set to BACnet this variable
establishes the unit's setpoint. When the Damper Mode is set
to Flow the BACnet Setpoint is a percentage of the MaxCFM
Setpoint. When the Damper Mode is set to Position the BACnet
Setpoint is the percentage the damper is open. When the Setpoint
Source is set not set to BACnet this variable has no impact on
controlling the damper.
SafetyStatus BI 1 C Represents the status of the safety circuit. Inactive = Open/Failure;
Active = Closed/OK
MaximumFPM MV 1 C
Represents the maximum setpoint velocity in fpm. The value this
variable is set to corresponds to a 10 VDC input to the actuator.
This value is set at the factory based on maximum velocity that
was selected at the time the unit was ordered. 1 = 500 fpm; = 1000
fpm; 3 = 1500 fpm; 4 = 2000 fpm; 5 = 2500 fpm; 6 = 3000 fpm; 7 =
3500 fpm; 8 = 4000 fpm
DamperMode MV 2 C
Establishes the mode of operation for the actuator. When in flow
control mode the actuator will view the setpoint as a target cfm
to maintain. When in position control mode the actuator will view
the setpoint percentage as a position to drive to (0% fully closed,
100% fully open). Whether the actuator is in Flow or Position
control mode the source of the setpoint will be determined by the
Setpoint Source variable. 1 = Flow; 2 = Position
SetpointSource MV 3 C
When set to BACnet the actuator uses the BACnet variable as
the setpoint. When set to Local AI it uses the actuator's second
analog input (S2) as the setpoint. When set to Zth the actuator
uses a handheld Zth module to establish the setpoint. 1 = Local AI;
2 = BACnet; 3 = ZTH

Damper Maintenance
Greenheck's dampers are designed to be trouble free and hassle free under normal operation. Dampers are to be
installed square and straight so as to prevent binding during operation. The following annual damper maintenance
suggestions will help to insure proper damper operation and increase the life expectancy of the damper.
Foreign Matter Over the course of time, dirt and grime may collect on damper surfaces. The
damper surfaces should be cleaned to prevent hindrance to airflow.
Moving Parts Make sure that parts such as linkage, bearings, blades, etc. that are intended to
move freely, can do so. Lubricating these components can prevent possible rusting
and unnecessary friction increase. Use only a moli-spray oil or similar graphite
based oil as regular lubricating oil will attract dirt.
Bearings: Synthetic, oil impregnated, and ball bearings (without grease fittings) do not require
lubrication. Ball bearings with grease fittings require only minimal grease.
Closure Remove foreign materials that may be interfering with blade closure or effective
sealing of the blades with each other or with the frame.
Operation While operating the damper through its full cycle, check to see that the blades open
and close properly. If there is a problem, check for loose linkage, especially at the
actuator. Tighten the linkage where required.
Minimum Installation Requirements
When installing the AMD-xx-TD, the installation should match as closely as possible to one othe examples shown on
pages 10 and 11. Failure to match the installation examples may negatively affect the performance and accuracy of
the AMD-xx-TD.
Avoid locating the AMD-xx-TD where they will be exposed to condensing moisture, such as downstream of a coil or
humidifier.
Design requirements for installing the AMD-xx-TD:
• Turbulent Airflow: The engineered design of the AMD-XX-TD sensor aperture will permit accurate airflow
measurement in the presence of moderate air turbulence as long as the AMD-XX-TD is installed the required
distance as shown above in the examples on pages 10 and 11.
• Stratified Airflow: The AMD-XX-TD should be mounted so that the probes cross any stratified airflow - not
parallel to flow.
• Airborne Contaminants: The levels of air filtration and cleanliness associated with commercial HVAC systems
are satisfactory for the AMD-XX-TD. Applications containing contaminants or condensing moisture may
impair airflow measurement accuracy and functionality.
