Using LTMCUF (Fast Device Replacement)

Backup service

In the HMI menu, when selecting the Backup service all the LTMR settings (configurations settings, LTMR and LTME commercial references, and custom logic file if used) will be downloaded to the internal non-volatile memory of LTMCUF.

The fastest way to back up the settings is to simultaneously press the two buttons with green circles for 3 seconds. The LTMCUF will start a backup sequence. This operation is equivalent to step 1 to 3 in the table below.

The other way to back up the LTMR settings is described in the table below.

Step	Description	Screen Display
1	Press to select the “HMI FDR” sub-menu and press “OK” to enter.
2	Press to select the “FDR backup now” and press “OK” to enter.
3	Press to select “Yes” and press “OK” to do the backup service. You can choose “No” to return to “FDR backup now” sub-menu. You can also press to return to the upper menu, or press on the right to return to the main menu.
4	Backup is in progress.
5	Backup is completed. After 5 seconds, the display will return to the main menu automatically.

Restore service

Restoration is done automatically during the LTMCUF startup sequence. It reads configuration of LTMR and compares it with the saved configuration. If the two configurations are different, LTMCUF starts to restore the configuration. LTMCUF will upload the backup memory to LTMR.

The restore operation is started if:

• the motor is not running,

• the LTMR and LTME commercial references match the previous configuration,

• Backed-up memory is valid (inside LTMCUF).

The restore command can also be done manually through the Restore menu.

If custom logic is used or the Ethernet network address has changed, LTMR will reboot.

The motor needs to be stopped during the entire FDR process.

Step	Description	Screen Display
1	Press to select the “HMI FDR” sub-menu and press “OK” to enter.
2	Press to select “FDR restore now” and press “OK” to enter. Verify that Backup service has been done before Restore service.
3	Press to select “Yes” and press “OK” to start the Restore service. You can choose “No” to return to “FDR restore now” sub-menu. You can also press to return to the upper menu, or press on the right to return to the main menu.
4	Restore is in progress.
5	Restore is completed. After 5 seconds, the display will return to the main menu automatically.

WARNING

unintended equipment operation LTMCUF only checks that the hardware configuration matches the saved memory. Before any operation, the user should verify that the configuration saved into LTMCUF is suitable for the application of the targeted LTMR. If a detected error message appears during FDR operation, a qualified operator should check the detected error root cause and recheck the configuration. Failure to follow these instructions can result in death, serious injury, or equipment damage.
