9.5 Performing the Material Setup
9.5.1 Overview
WARNING
Danger of cutting on sharp edges of the material web!
Severe cutting injuries caused by the edges of the moving material
web.
►
Never touch the edges of moving material webs.
►
Carry out the material setup only when the production machine
is stationary.
During the material setup the controller is automatically adjusted
to the properties of the material to be scanned.
9.5.1.1 When does a material setup have to be carried out?
In order to be able to achieve optimum guiding results, a material
setup must be carried out during / after the following work:
■ During the initial commissioning of the web guiding system
■ With optical edge sensor (IR 2011, IR 2012): After changing
over to a material with other contrast characteristics (e.g. film
with a different material transparency)
■ With ultrasonic edge sensors (US2010): After changing over to
a material with different sound absorption properties
■ After cleaning a dirty sensor
9.5.1.2 Manual or automatic material setup?
The material setup can be run automatically or manually.
■ The automatic material setup describes the normal procedure
for saving the bright / dark values of the sensors.
■ The manual material setup should always be used if the contrast
that has to be scanned is critical.
