Installation and wiring
The infrared sensors do not detect the door in its closed state, what needs to be
considered?
The infra-red sensors have only a specific working range. In particular for the two external
sensors, 7030.120 infrared access sensor and 7030.200 CAN bus Access care must be
taken to ensure that the sensors are not placed too near the door because otherwise the
infrared light can no longer be reflected correctly. An overview of the possible working ranges
is shown in the following table:
In the delivered state, a protective foil that covers the front of the sensor protects it from
transport damage. This foil must be removed when the sensor is installed.
What is the pin assignment of the 7030.190 universal sensor when the S
0
or the
Wiegand interface is used?
If the 7030.190 universal sensor is used as S
0
interface, pin 5 or pin 6 (pulse) and pin 2
(GND) must be used. The universal sensor so permits the connection of two devices with S
0
interface:
If the "7030.190 universal sensor" is used as Wiegand interface, pin 5 and pin 6 must be
used as data lines. Consequently, only one reader device with Wiegand interface can be
connected to a universal sensor. Pin 1 and pin 2 can also serve as 24 V power source:
