Front Panel Lockout
In order to avoid the accidental modification of a set value during manual operation, the
rotary knobs or the touchscreen can be locked so that no change in values will be accepted
without prior unlocking.
How to Lock the Front Panel:
1.
In the main page, tap the lock symbol
(upper right corner).
2.
In the settings page “HMI Lock” you are then asked to chose between a complete
HMI (“Lock all”) lock or one where the On/Off button is still usable (“ON/ OFF
possible”), resp. chose to activate the additional PIN (“Enable PIN”). The unit would
later request to enter this PIN every time you want to unlock the front panel, until
the PIN is deactivated again.
3.
Activate the lock with
. The status “Locked” as shown in the figure to the right.
If an attempt is made to alter something while the front panel is locked, a dialog box
appears in the display asking if the lock should be disabled.
How to Unlock the Front Panel:
1.
Tap any part of the touchscreen of the locked front panel, or turn one of the rotary
knobs or press the “On/Off” button (only in “Lock all” situation).
2.
This request pop-up will appear:
.
3.
Unlock the front panel by tapping on “Tap to unlock” within 5 seconds, otherwise
the pop-up will disappear and the front panel remains locked. In case the additional
PIN code lock has been activated in the menu “HMI Lock”, another dialog box will
pop up asking you to enter the PIN before it unlocks the front panel.

Limits Settings Lock
In order to avoid changes in adjustment limits (also see section 6.4.4, “Adjustment or User
Limits” on page 74) by an unauthorized user, the screen with the adjustment limit settings
(“Limits”) can be locked by a PIN code. When locked, the menu pages “3.Limits” in SETTINGS
and “Profiles” in MENU will become inaccessible until the lock is removed by entering the
correct PIN or in case it has been forgotten, by resetting the unit as last resort.
How to Lock the “Limits” settings:
1.
While the DC Input is switched off, tap the touch area
on the main
screen.
2.
In the menu tap “Limits Lock”.
3.
In the next page set the check mark for “Lock”.
Note: The same PIN as for the front panel lock is used here. It should be set before
activating the Limits lock. See section 6.7, "Front Panel Lockout” on page 90.
