Make sure the inverter is NOT running.
Updating priority sequence, unless informed by us:
If the menu on top of the screen seems less than shown below, it indicates that the system has been set to remote control mode.
Since V1330, even if the module is indicated “Offline” due to the module firmware version is too new or too old for HMI to communicate, you can still update it.
In HMI version 1330 or earlier, the Updating page is not available in English, you have to log in with an operator password and change the language to Chinese. You can check the following 4 English-Chinese comparing figures to find how to change it back to English again.
Login and then you can see all the menus.
In HMI version 1340 or later, the Updating page is English.
Open the front door, plug the USB disk to the USB port of the HMI
Make sure that the HMI firmware: monitor.tar.gz, is NOT in the USB disk at this moment
To UPDATE U2 Firmware, just repeat the procedures above, the differences are:
Before leaving the site, DO remember to set the HMI to Remote Control mode if it was not in this mode!
If any failure happened in updating operations, plug the USB disk in the USB port of the HMI
DELETE the HMI updating file BEFORE PLUGGING!
follow the following flow chart.
If the internal communication failed, the updating flow chart must be strictly followed. The first step is always updating U2-15#. And a hard reboot is necessary, remind the firmware version of the U2. After updating failure, the updating must be implemented one module by one module, and the ID is always 15#, and every time there should always be one module plugged with comm plug.
AC module (U1) updating in case of failure
DC module (U1) updating in case of failure
U2 updating in case of failure
Prepare the LOGO file and copy it to the root directory of the USB disk. The LOGO file should conform to the following requests,
