5. FIELD STARTUP
The AAON Airflow Signal Processor has been configured by the factory for the specific application.
Therefore, the only parameters that need to be configured in the field are the network communication
settings, with the exception of Modbus® Slave communication with WattMaster Controls which has
been configured at the factory, and the High/Low Alarm Option if ordered. Communication settings
will be configured under the Tech Configuration Menu (see Section 5.1). The High/Low Alarm Option
will be configured under the Field Setup Menu (see Section 5.2).
During field startup, if the displayed value on the AAON Airflow Signal Processor does not match the
reading from the Balancer, a Flow Correction (K-Factor) can also be entered under the Field Setup
Menu (see Section 5.2).
If required, the AAON Factory Settings can be checked or reconfigured following procedures outlined
in Section 6. If parameters are reconfigured incorrectly, all device settings can be restored to the
original AAON Factory Settings (see Section 5.2.3). This guide is intended for field startup only of the
AAON Airflow Signal Processor. The full AAON Outdoor Airflow Measurement System O&M can be
downloaded from AAON’s website at www.AAON.com.
