The yellow LED "Line Transparent" signalizes that the communication line is established
between the CC–CO master and CC–CO slave.

communication line and modifies the tuning of the CC–CO accordingly. This process can
take up to 15 secs and should be followed by a "Line Transparent" signal. Additionally,
for the duration the button is being pressed the 3 upper LEDs and the DOK relay are
connected so that the signalizing elements can be checked for their operatability at the
same time.
To annote that configuration Master or Slave is set, make a cross on the corresponding
position on the label to be found at the upper side of the housing.
