Behaviour after switching on the mains
voltage
After the mains voltage is switched on, the display
(B) lights up permanently.
If the device has not yet been connected, teach-in mode
will be activated during the first 3 minutes after the mains
voltage has been switched on. You will find further infor-
mation about connecting your device in the next section.
