Locking the control panel (HMI)
In order to avoid the accidental alteration of a value during manual operation the rotary knobs or the touchscreen can be
locked so that no alteration of values will be accepted without prior unlocking.

How to lock the HMI
1.
In the main page, tap the lock symbol
(upper right corner).
2.
The
Lock
screen will appear where you can select to lock the HMI completely or with the exception of the button
On/
Off
by enabling
On/Off possible during HMI lock
. Additionally, you can decide to activate the additional
PIN for user
interface lock
. The device would later request to enter this PIN every time you want to unlock the HMI.
3.
Activate the lock with
Start
. The device will jump back to the main screen and dim it.
If an attempt is made to tap the screen or rotate a knob whilst the HMI is locked, a requester appears in the display asking if
the lock should be disabled.

Locking the adjustment limits and user profiles
In order to avoid the alteration of the adjustment limits (also see
“3.4.4. Adjustment limits“) by an unprivileged user, the screen
with the adjustment limit settings (
Limits
) can be locked by a PIN code. This will lock group
Limits
in the
Settings
menu and
menu
Profiles
until the lock is removed by entering the correct PIN or, in case it has been forgotten, by resetting the device
to factory default.

How to lock the Limits and Profiles
1.
While the DC output is switched off, tap touch area
on the main screen. In case the HMI is locked, it has to be
unlocked first, probably by entering the PIN. After this, menu page
Lock
will be entered.

In the switch next to
Lock limits and profiles with user PIN
.
3.
Leave the
Settings
menu.
The same PIN as for the HMI lock is used here. It should be set before activating the Limits lock. See “3.7.
Locking the control panel (HMI)“
Be careful to enable the lock if you are unsure what PIN is currently set. In doubt use ESC to exit the
menu page. In menu page Lock you can define a different PIN, but not without entering the old one.
