The pin assignment can be found in the chapter Cabling.

The first zone: Zone 1

In principle, you can set up and wire the first zone in the same way as all other zones. The conveying process starts as soon as a package is placed in the detection range of the sensor.

However, since the feeding of packages takes place at the beginning of zone 1 and the sensor is usually at the end of the zone, it may make sense to use an additional sensor or push button at the beginning of zone 1. The additional sensor or push button is shown as "optional" in the figure.

Connect the signal of the sensor or push button to pin 4 of X02 of the first EP7402. The pin assignment can be found in the chapter Digital input/outputs.

The last zone

In the factory setting of EP7402, the conveying process stops as soon as a package reaches the detection range of the sensor of the last zone.

The wiring and configuration of the last zone depends on whether the last zone is connected to channel 1 or channel 2 of an EP7402.

Sensor signals

With the factory settings, the EP7402 expects a digital Hi level when a sensor detects a package.

If you are using sensors that provide a low-active signal, change the following parameters:
