Example: This function may be used for Corona / Plasma pre-treatment security. A
corona treatment device modifies the surface of materials especially plastic
material as a preparation for the ink jet print. The corona treatment and the
ink jet print happen on the fly. In case the production line stops or gets too
slow there is the danger that the surface of the material can be destroyed
by the corona treatment if the device isn't stopped. The stop can be
managed by the speed dependent output of the Printer. In this example the
speed is set to 30 m/min. The speed is
detected through the encoder signals which are also used for the
positioning of the Printer printout. As soon as the production line reaches or
exceeds the set speed the assigned output will switch to a high level. This
high level remains as long as the speed doesn't drop below 27 m/min (30
m/min -10%). If the speed drops below the lower limit the output will switch
to a low level. The output level is used to control the on/off of the corona
treatment electrode.
