WARNING
If the user confirms the "Standard Command" function by pressing the "Reset to
factory settings" button, this causes the device to be immediately reset to the as-
delivered state.
Downstream processes can be affected. The behavior of the current outputs can change.

Make sure that downstream processes are not started unintentionally.
To perform a reset there is no additional locking, e.g. device unlocking is not required to
perform a reset. Furthermore, the device status is also reset. Any customer-specific
configuration carried out at the factory is not affected by a reset (customer-specific
configuration remains).
The following parameters are
not
reset when a reset is performed:
• Minimum µC-Temperature
• Maximum μC-Temperature
• Last Diagnostic (LST)
• Operating hours
