CONFIGURATION RESTORE
If the user needs the complete factory restoration of positioner parameters (including current and
pressure sensor calibrations), they should insert two magnetic screwdrivers (one in each hole - Z and S)
in local adjustment and restart the equipment, awaiting numerical counting until the word "donE" is shown
on display. After that, simply reconfigure it with the desired values for the application.

JUMPER CONFIGURATION FOR LOCAL ADJUST AND WRITE PROTECTION

(ADJL1). Figure 3.2 presents those jumpers.
