6.4 Inputs
6.4.1 General
The assignment of the sensors to the inputs is predetermined�
Input 1 = sensor 1 with normally closed output (upper value)
Input 2 = sensor 2 with normally open output (lower value)
The connection of mechanical switch contacts is not recommended since
they tend to bounce and produce faulty pulses�
Terminals 5 and 7 can be used for the sensor supplies�
6.4.2 Connection of sensor 1 (upper switching point)
For the correct operation use a sensor with normally closed output
(→ 3.1 Functionality).
