5-wire special operation
In case that only 5 lines are available
to connect the device and the M-wire
cannot be connected, you can use the
device in 5-wire special operation.
!
Installing a wire bridge between the wires b and M is only permitted
when observing some conditions.. For a solution for your project,
please contact our hotline.
Commissioning
!
First install the system completely, than connect it to
the mains voltage!
Install the devices of the system completely.
V1 and V2 must not be connected with the P-, a- or b-wire.
When connecting the video wires V1 (+) and V2 (−) the polarity
must be observed.
Proof the a-, b- and P-wire against each other on short-circuit.
Switch on the main voltage.
Error detection and indication
Errors are signalled optically and acoustically: single error tone and per-
manent flashing of both LEDs.
error cause
indication

error tone
our solution
a- and P-wire are
mixed or short-
circuited
both LEDs
are flashing
change a- and P-wire or remove
short-circuit,
device is in standby mode again
a- or M-wire not con-
nected or not sup-
plied
connect the a- or M-wire or check
the power supply,
device is in standby mode again
button stucks
(press longer than 15
seconds)
release button at the device or
release floor push button,
device is in standby mode
again
