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.
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.
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).
