LD1
Ground – red control-LED
Ground – must light up, if protective earth screw is with-
drawn
Otherwise grounding is on
LD2
green + 24 V
Is on, if 24 volt circuit OK
Comes off in case of by-pass in 24 volt circuit
LD3
green + 32 V
Is on, if system connected to mains voltage
LD4
red control-LED
For MF key S1 – is blinking, if button is pressed
Multifunctional key Function, after pulses have been given
1 pulse
Releases an opening movement (AKI)
