Setting Damper Control
Skip this step if you are using high speed actuators from Siemens Industry, Inc.
The application has the option of not inverting DO2 operation. An inverted RETC DO2
means that to hold a position, the RETC DO2 must remain on.
Set INVERT DO2 by selecting one of the following:
– YES to invert RETC DO2 (default).
– NO for non-inverted operation.
Checkout of Damper
1. Set DMPR CMD to 100.0. The damper moves to the fully opened position.
2. Set DMPR CMD to -100.0. The damper moves to the fully closed position.
3. If the damper moves opposite of the way it should, reverse the wires on EXTN DO1
and RETC DO2 on the FHC terminal block.
4. Release DMPR CMD. Verify the point has been released.
(Optional) Setting Airflow Input Type
If you are using a Siemens terminal box/Venturi valve with an OAVS sensor, you can
skip this section.
Otherwise, if the job uses differential pressure sensors, Vortex shedders or another
linear device made by others, perform the steps in this section.
NOTE: When using AI-3 to input the airflow, the input can’t be used as an input for
External Face Area.
Setting Transmitter Range
1. Set TRANS RANGE to the value printed on the differential pressure transmitter,
typically: 0.1 in. WC (25.3 Pa), 0.25 in. WC (62.275 Pa), 0.5 in. WC (124.55 Pa), or
1.0 in. WC (249.1 Pa). Any value from 0.0 to 2.55 in. WC is acceptable. The default
value is 0 in. WC.
2. Zero the transmitter by doing one of the following:
– If an Autozero module is not present, proceed to
Calibrating the DP Transmitter
without an Autozero Module
.
– If an Autozero module is present, proceed to
Calibrating with an Autozero
Module
.
NOTE:
If the milliamp reading from the transmitter is less than 3.7 mA or more than 4.3 mA
with the high and low ports disconnected, you must zero the DP transmitter using the
zero screw on the DP transmitter.
