3.
Set CAL AIR to
YES
. The calibration will take approximately 3 seconds. When
calibration is completed, this point will automatically change back to NO.
4.
When
CAL AIR
changes back to NO, reconnect the HI and the LO tubing to
the transmitter (or to the flow sensor if you disconnected it there).
(Optional) Calibrating with an Autozero Module
This section is for fume hoods with an external pressure sensor and 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. Set CAL AIR to YES.
When calibration is completed, this point will automatically change back to NO.
AVS FAILMODE
AVS FAILMODE is a point that describes how the Venturi Air Valve will respond if the
Air Velocity Sensor (AVS1) fails.
Set AVS FAILMODE to the desired value.
AVS1 failure and AVS FAILMODE values.

Setting Airflow Control — Application 2942
Refer to the chart below. If you have a setpoint that will fall below the value in this
chart, you must perform these steps; otherwise, these steps can be skipped.
Airflows below 350 fpm are difficult to sense precisely. If your valve will be operating
below 350 fpm (see the Table
Venturi Airflow @ 350 fpm
for the corresponding cfm),
perform the following steps.
