4.10 Save and Restore
The controller has a feature to save and then restore on an SD card the actual unit settings. This
feature can be useful when a software upgrade is needed or to keep a copy of the actual settings
for future usages like a controller replacement.
In case of backup, part of the settings like number of starts and running hours may not be restored.
Backups may be done periodically to save a more recent status of the settings.
This page has all the setpoints to command a save and/or a restore of a previously saved
parameter file.

Before proceeding be sure that the SD card is properly fitted in its slot as shown in the picture. A
status of the SD card is also displayed in the same page to check if it’s allowed to save the
parameters.
To save a copy of the settings the SD Card State must be ReadWrite (1). If the State is ReadOnly (2)
check the position of the card-lock.
