Setting Inverter ID
There is an EEROM in the inverter which stores its
supported LCD type ID code. If you replace the LCD with
a different brand, the ID information in the inverter EEROM
should be updated.
Follow the steps below to set the LCD Inverter ID:
1. Boot from the Utility Program Diskette.
2. Select Inverter ID Utility from PC DOS 7.0 Startup
Menu.
3. Follow the instructions on screen to read current or to
set a new inverter ID code.
Note: When you set a new inverter ID and the new
LCD is not yet enabled (to function), connect an
external monitor to see the program execution
process.
Important: Make sure the new ID code you choose
corresponds with the LCD brand and type. If you
write a wrong ID into the inverter, just reboot and
re-execute the program and input the correct ID code.
4. Restart computer - the new LCD should work
normally.
Note: If LCD does not display after changing the ID
code, make sure you write the correct ID code, or try
reseating the LCD FPC cable connectors.
