Backing up settings made by the customer
The factory operating parameters are always preset in replacement units. All settings made
by the customer to the original electronic drive unit are lost when it is replaced. To preserve
your custom settings, you have the following options:
1. Back up all your settings as a parameter set in a HPU.
2. Load a backup parameter set by means of a HPU into the new electronic drive unit.
3. Program the individual settings into the new electronic drive unit by hand.
4. Observe the operating instructions of the electronic drive unit and the HPU.
