3.4.7 Control panel (HMI) lock
In order to avoid the accidental alteration of a value during manual operation, the rotary knobs and the buttons can
be locked so that no action is accepted without prior unlocking.
► How to lock the HMI
1.
While the DC output (1 or 2) is switched off, press button Settings .
2.
In the menu use the left knob to navigate to HMI Setup and press the knob.
3.
In menu HMI Setup use the knob to select and configure the lower four parameters related to the HMI lock.
For details about the single parameter see section
«3.4.3.3. Menu “HMI Setup”».
4.
The HMI lock is activated with Lock HMI? = Yes and leaving the menu. The active lock is indicated by
symbol .
Alternatively to the simple lock, which can be unlocked very easily by every person and thus offers no protection
against intentional misuse, a PIN can set up and activated, which then is requested to be entered every time the
HMI is going to be unlocked.
► How to lock the HMI with PIN
Don’t activate the PIN lock if you are unsure about the current PIN! It can be changed, but only
if the current PIN is entered. Resetting the device via remote command will also reset the PIN
to the default 0000.
