Configure Flow Settings
To configure the flow settings for the RAC System, perform the
following steps:
Note:
The Impactor
Assembly utilizes a critical
orifice to achieve the
desired median flow.
It is recommended that the
Median flow setting be
configured with the
impactor installed.
1. Ensure that the power is removed from the controller.
2. Remove the DIP Switch Cover Plate to expose the DIP Switch.
Verify DIP SW 1 and 6 are ON for MODBUS mode (default
setting). If any address other than address 1 is required, set DIP SW
1 through 5 to the desired address.
3. See Pages 3-5 and 3-6 for DIP Switch definitions and addressing.
4. Attach a flow meter to the tubing connected to the Vacuum Port on
the bottom of the RAC Controller. Connect the other end of the
flow meter to a needle valve that is attached to a vacuum source.
5. Attach the locking power jack to the Controller as shown in Figure
3-14. Confirm that the Power LED is on.
