To set up the EBTRON EB-FlowII EF-A2000-U Airflow Measurement with Temperature and Alarm Capability, follow these steps:
1. Verify that the sensor probes are located as per the EBTRON published installation guides. The probes should be properly spaced with the airflow arrows pointing in the direction of airflow.
2. Install and wire the transmitter according to the EF-A2000-U Wiring Guide provided with the transmitter. Ensure that power is provided to the transmitter.
3. Clean the ductwork and ensure it is free of debris before starting the fan.
4. Energize power to the transformer. Check the LCD for any power-up faults. If any faults are detected, resolve them or contact EBTRON customer service before proceeding. If extension cables have been added, enter the extension cable length into the transmitter as per the Operations and Maintenance Manual.
5. The transmitter is factory calibrated and fully functional in I-P units (ft, FPM, CFM, °F). Airflow (FPM) and temperature (°F) are displayed on the LCD. If SI units are required, refer to the Operations and Maintenance Manual. The default airflow output is set to actual airflow (FPM, CFM). If standard (mass) airflow (SFPM, SCFM) is required, refer to the Operations and Maintenance Manual.
6. If two probes are provided and each probe is used in a separate measurement location (e.g., intake and exhaust paths of an ERV), enter the MAIN MENU by pressing the ↑↓ arrow buttons simultaneously. Navigate to the SETTINGS menu and set the LOCATIONS parameter to 2. Location 1 is the probe connected to receptacle C1.
7. Enter the area of the opening where the probes are mounted manually or calculate it using the area wizard tool (AREA WIZ). The area parameter, AREA, can be entered manually through the SETTINGS menu. Using the correct area is crucial for accurate volumetric airflow (CFM) measurement.
8. If analog output signals are used, verify that the transmitter is configured to match the analog input requirements of the host controller. Check the AOUT parameter and adjust it if necessary.
9. The analog output signal for airflow (AO1) is linear. The default minimum scale reading is 0 FPM and the full scale reading is 3000 FPM. If custom airflow scaling or unit of measure is required, refer to the Operations and Maintenance Manual.
10. If the transmitter is configured for two locations, repeat step 9 for AO2. The default output for AO2 is Airflow2 (AF2). If custom temperature scaling is required, refer to the Operations and Maintenance Manual.
11. If contact closure alarming is required, navigate to the RELAY submenu in the SETTINGS menu. Set the R1 ASGN parameter to ALRM (high/low airflow alarm) or TRBL (System Status Alarm). Adjust the R1 STATUS parameter if necessary.
12. Once the setup is complete, refer to the Operations and Maintenance Manual for more information on customization and additional features.
For more detailed information and troubleshooting, consult the Operations and Maintenance Manual. If you need further assistance, you can contact EBTRON Customer Service at 1-800-2EBTRON (1-800-232-8766) or reach out to your local EBTRON representative.
