WARNING: The fan controllers contain high voltage capacitors that take time to discharge after removal of mains supply.
Before working on the fan controller, ensure isolation of mains supply from line inputs at the fan controller’s disconnect if
installed. Wait three (3) minutes for capacitors to discharge to safe voltage levels. Failure to do so may result in personal
injury or death. Darkened display LEDs are not an indication of safe voltage levels.
Connections
1. Disconnect AC mains power from the fan via the included rotary disconnect or other means, and then wait for a darkened LED
display on the fan controller.
2. Remove the lower VFD cover and install the Modbus card into the rear of the lower cover. If an ESFR system interface relay is
present, relocate it to the interior wall of the VFD.
3. Install the Modbus cable into the main drive housing with the appropriate fitting, e.g. cord grip connector or EMT connector.
4. Install jumpers between terminals 1,4, and 13B.
5. Connect the data cable as shown on the following page. Pay special attention to the polarity for MBA, MBB. The cable shield's drain
lead and reference line (if present) connect to terminal #1 on the Modbus card.
6. Remove the free end of the Modbus card/VFD patch cable from the two plastic retainer clips, and then plug the free end of the patch
cable into the VFD's accessory card socket (located below the EPM module).
7. Reinstall the VFD's lower cover while being mindful of the bare drain leads slack (if present). Incidental contact between the drain
lead and the VFD's input/output leads can result in catastrophic damage to all other devices on the Modbus loop!
8. Reapply power to the fan. The BAFWorks
®
application will now be able to connect to this fan on the network.
Note: The following actions will result in a communications loss and subsequent fan shutdown:
• Closing the BAFWorks application
• iPad
®
, gateway, or Wi-Fi router power loss
• Modbus data loop wire break
• iPad out of range of the Wi-Fi router
Parameter changes
The following parameter changes are required for proper operation:
WARNING: Before making parameter changes, ensure that the fan is stopped.
To change fan parameters:
1. Press on the fan controller to enter programming mode.
2. Press or until parameter P199 is displayed.
3. Press to view the current setting.
4. Press or to change the setting to 0.
5. Press to save the change.
Repeat the steps above to navigate to and change the remaining required parameters. When the last change is completed, the
controller will return to the normal operational screen.
