6 SOFTWARE FUNCTIONS
The real power with a microprocessor based sensor is that the sensor learns what the
products and the stream look like and make decisions according to this.
Before actual settings are discussed, first a short description of the major functions and
terms.
6.1 Mode Setting
The DENEX Gripper LED has a Single Production Mode and a Double Production Mode.
The difference is the Blocking Zone, see below. There are also modes for replacement of
mechanical fingers
There are four DIP-switches that tell the sensor which application it should be set for.
It is very important to set the right application!
6.2 Blocking Function
This function will eliminate false counts due to double edges or a cut-edge-first delivery.
The sensor will count edges coming within the blocking zone as one product. In
productions using stitches, extra pulses due to the stitch are blocked out by this function.
The blocking zone is a dynamic value that constantly adapts to the average distance
between copies. It will be either 15% or 30 % of the mean lap, depending on application.
The average distance between copies is 100%, see figure 6.2.1.
If speed sensor pulses are used, the blocking will switch to a fixed number of pulses
instead of a dynamic time.
