(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.
Linear Flow Input Signal
This section is used if the job has Vortex shedders or another linear device made by
others. CAL SETUP does not function in this mode.
1. Set TRANS RANGE to = 0 (default value).
TRANS RANGE must be 0 for the linear input function to work.
2. Enter the velocity range of the linear device into LINEAR FL RG.
3. Set FLOW COEF to 1.
Proceed to
Flow Accuracy Verification
.
(Optional) Calibrating the DP Transmitter without an
Autozero Module
This section applies for fume hoods with an external pressure sensor and without an
Autozero module. If the DP Transmitter is slightly out of adjustment, you can
compensate for that within the controller.
1.
Set REPORT to
AIRFLOW IN
.
2.
Remove the tubing connected at the HI and LO ports of the DP transmitter
(the tubing can be disconnected at the flow sensor if desired). Both ports must
be disconnected to calibrate the transmitter.
