Module-based Models Firmware Updating Instruction

Tools Preparation

  • One FAT32 formatted USB disk. Smaller than 16GB.
  • Firmwares:

    AC module U1

    Center control board U2

    HMI

    AC_U1_V[version].hex

    U2_V[version].hex

    monitor.tar.gz

The U2 is the center control board referred in the communication protocol file.

Before updating

Updating priority sequence, unless informed by us:

  1. HMI,
  2. AC modules,
  3. U2.

Make sure the inverter is not running.

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.

  1. Select Ctrl mode-Local Manual to show the complete menu.
  2. Remember to switch back to remote control after the updating operations.
  3. Login as super administrator with super password
  4. Check System- module on the HMI, whether the information conforming to actual configuration.
  5. Check the ACPCU U1 DSP versions in “info-AC details”, HMI version is in the left bottom of the screen.
  6. Change AC module number from 1 to 2/3/4/5(depending on the actual module quantity), if you can read the parameters, it means the module is online. Select AC module 11, you will read the U2 DSP version.
  7. Double check and make sure all modules are online in Info-Status.

Updating AC module

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

  1. Enter the Upgrade page in Settings.
  2. Select Type as DCAC, and Module
  3. Check all the modules that need to be updated
  4. Click Import, to load proper .hex file, named AC_U1_V[version].hex;
  5. Click Upgrade, then input the password 123456；
  6. Wait until the progress bar reaches 100%, updating completes.
  7. Hard rebooting is requested before the new firmware works.
  8. After the hard reboot, check whether the versions are right in “Info-AC details”.
  9. If any warning notes that updating failed, jump to Exception procedure in case of failure
  10. May you never need to refer to Exception procedure in case of failure

To UPDATE U2 Firmware, just repeat the procedures above, the differences are:

  1. Select Type as U2
  2. Check on #11
  3. Click Import, Select U2_V[version].hex

Updating HMI

  1. The PCS should be powered off from both AC and DC supply.
  2. Copy the HMI firmware file monitor.tar.gz into the USB disk, plug the USB disk to the USB port of the HMI (open the front door).
  3. Power on the PCS from AC.
  4. When HMI starting up, it will load the updating file and do the updating automatically. You will hear a “beep-” sound.
  5. Wait until it stops on Home page, it will feel like nothing happened. But the version in bottom of the HMI should have changed
  6. Unplug the USB disk, delete the HMI file monitor.tar.gz

Note,

In HMI version 1320, the Updating page is not available in English, you have to log in with a 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.

Exception procedure in case of failure

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.

graph TD; A(Start)-->B["Update U2 (#15)"]; B-->C{U2 updating success?}; C-->|Yes|D[1 power off
2 reconnect all plugs to U2
3 power on]; D-->E{Is there any DC module?}; E-->|Yes|F[1 plug the comm cable to #1 DC module
2 update DC module #15 on HMI]; F-->G{DC module updating success?}; G-->|Yes|H[1 unplug the comm cable from #1 DC module
2 Plug the comm cable to #2 DC module
3 update DC module #15 on HMI]; H-->I{DC module updating success?}; I-->|Yes|J[Repeat the DC module updating procedures until all modules updated]; J-->K[unplug the comm cables from all DC modules]; K-->L[1 plug the comm cable to #1 AC module
2 update AC module #15 on HMI]; L-->M{AC module updating success?}; M-->|Yes|N[1 unplug the comm cable from #1 AC module
2 Plug the comm cable to #2 AC module
3 update DC module #15 on HMI]; N-->O{AC module updating success?}; O-->|Yes|P[Repeat the AC module updating procedures until all modules updated]; P-->Q{HMI module updating needed?}; Q-->|Yes|R[1 power off
2 plug the USB disk with HMI updating file
3 power on and wait for updating
4 unplug the USB disk]; R-->S[1 Power off
2 restore all comm wiring
3 Power on]; S-->T{Versions right?}; T-->|Yes|U(END); C-->|No|ZZZ[contact us]; G-->|No|ZZZ[contact us]; I-->|No|ZZZ[contact us]; M-->|No|ZZZ[contact us]; O-->|No|ZZZ[contact us]; R-->|No|ZZZ[contact us]; T-->|No|ZZZ[contact us];

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

How to apply customized LOGO to HMI

Prepare the LOGO file and copy it to the root directory of the USB disk. The LOGO file should conform to the following requests,

  • .PNG format
  • Transparent background
  • Height 46 pixels (best performance, lower height can also work but may not be symmetry), the width can be determined by the logo itself.
  • Named as logo.png

Switch control mode to Local manual if necessary. Login as super administrator with password , Plug the USB disk to the USB port of the HMI. Click Settings-Local-change logo.

A dialog box will remind to reboot to take effect. Hard reboot the ACPCU and the Sinexcel LOGO will be replaced by the new LOGO.
