3.7 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 padlock symbol in upper right corner. If the DC input is switched on in this moment, the
lock is immediately effective.
2. Otherwise 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.
How to unlock the HMI
1. Tap any area on the touchscreen or rotate any knob or press the button “On/Off” (only in full lock).
2. This request pop-up will appear: .
3. Unlock the HMI by tapping on Unlock within 5 seconds, otherwise the pop-up will disappear and the HMI remains locked.
In case the additional PIN code lock has been activated in the Lock screen, another requester will pop up, asking you
to enter the PIN before it nally unlocks the HMI.
3.8 Locking the adjustment limits and user proles
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 Proles 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 Proles
1. While the DC input is switched off, tap the padlock symbol on the main screen. In case the HMI is locked, it has
to be unlocked rst. After this, menu page Lock will be entered.
2. In the switch next to Lock limits and proles 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 dene a different PIN, but not without entering the old one.
How to unlock the Limits and Proles
1. While the DC input is switched off, tap touch area on the main screen.
2. In the menu tap on HMI setup, then on group Lock.
3. In the group tap on “Unlock limits and proles”. You will be requested to enter the 4-digit PIN.
4. Deactivate the lock by entering the correct PIN.
