O/1 24 V DC reference sensors
I/2 Buffer zone sensor 2
O/3

O/3 0 V reference sensors
I/2 O/1
I/4 Buffer zone sensor 1
I/2 O/1
The sensor inputs are negative-switching (normally-closed).
If 24 V DC is applied, the small parts conveyor will be switched on.
The 4-pin plug “Sensors” wired at the factory bridges the sensor
inputs I/2 and I/4 with 24 V DC. The inputs I/25 and I/26 at the con-
nection “Controller” are then connected internally with the reference
voltage.

Connector socket “Controller” on the Sortbox
O/7 24 V DC reference voltage
I/25 Buffer zone sensor 1
I/6 Buffer zone sensor 2
I/24 Sortbox Buffer zone sensor 3
I/5 Sortbox Buffer zone sensor 4
I/23 Sortbox Buffer zone sensor 5
I/4 Sortbox Buffer zone sensor 6
Sensor inputs I/25 and I/26 are already connected internally to
24 V DC via the plug “Sensors”. The plug “Controller” wired at the
factory bridges the connections “Buffer zone sensors 3...6”.
