Installation, Operation, and Maintenance Instructions
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.
Safety Warning:
Improper installation, adjustment, alteration, service or maintenance can cause property damage, injury or death. Read the installation, operating, and maintenance instructions thoroughly before installing or servicing this equipment.
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 highly recommended. Do not store at temperatures in excess of 100°F (37ºC).
Due to continuing research, Greenheck reserves the right to change specifications without notice.
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.
Spreader Bar
Attachments
Multi section dampers
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
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.
Installation- Failure to follow instructions will void all warranties
1. Ensure the AMD-xx-TD series damper 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.
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.

SAFETY DANGER !
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 30 seconds. Once the start-up sequence has been completed the transmitter's display will show the measured volumetric airflow rate, velocity, and ambient air temperature (see below). Under normal operation a dot in the upper right corner of the display will blink rapidly (4 times per second).
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 Dampers 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’s Ordered with a Factory Supplied Controller
When you order a factory supplied controller, it comes with a Greenheck exclusive VAFB24-BAC-GTD actuator which has the controller integrated inside of it. The actuator/controller is configured by the factory at the time the unit is 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 the all the BACnet datapoints is listed in Table 1 (page 7).

The controller is designed to modulate the AMD-xx­TD 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.

This controller is designed to modulate the AMD­xx-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 BACnetSetpoint 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) BACnetSetpoint = (Target CFM / Maximum CFM)
BACnetSetpoint = (6,000 / 8,000) = 75%
With a BACnetSetpoint 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 BACnetSetpoint 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 BACnetSetpoint 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.

BACnet Data Point List
Table 1 lists and describes all of the BACnet data points associated with the controller inside the actuator of BACnet enabled AMD-TD series dampers.
Name Type # Access Description
Greenheck AMD-TD AI 1 C Displays the application version
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.
BACnetSetpoint 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 = BACnet; 2 = Local AI; 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.
Our Commitment
As a result of our commitment to continuous improvement, Greenheck reserves the right to change specifications without notice.
Specific Greenheck product warranties can be located on greenheck.com within the product area tabs and listed in the Library under Warranties.
