3.7 Control panel (HMI) lock

complete HMI lock (check mark set for “ Lock HMI ”) or a partial lock where the On/
Off button on the front of the device is still usable (check mark also set for “ On/Off ”).
You may also chose to activate the additional PIN (“ Enable PIN ”). The device would
later request to enter this PIN every time you want to unlock the HMI, until the PIN is
deactivated again.
Be careful with the “ Enable PIN ” option if you are unsure what PIN is currently set. If you
are unsure, use “ Change PIN ” to define a new one.
