Configuration menu blocking
This function prevents unauthorised access to the configuration menu using the buttons on the
front of the device. When the function is active, all buttons will function normally except for
the configuration menu no longer being accessible when INCREASE and DECREASE are
pressed simultaneously. The function can be activated via the display, Regio tool
©
and
Modbus. Please note that if the function is activated via the display, re-entering the parameter
list via the display will be prevented. The function must then be deactivated using Regio tool
©
.
