ADVANCED CONFIGURATION MODE (SG4-P)
SG Extended GUI software (Graphic User Interface, GUI) for PC allows the user to set
ESPE advanced configuration. Many parameters are available to customize ESPE behav-
ior for specific applications.
Since ESPE parameters can be safety critical and PC software cannot be guaranteed as a
saf
ety component, a safe configuration procedure has to be followed.
Configuration procedure on GUI can be done by authorized personnel only. Such per-
sonnel must be sure that protected dangerous machine has no access during configura-
tion procedure.
There are 3 different kinds of operator that c
an use the GUI with 3 different levels of
authorizations.
System Integrator: has al
l the possible authorizations and can set every configuration
on the GUI
Maintainer: c
an upload the configurations (saved on the GUI) on the light curtain and
use the GUI for monitoring the system, but he can't create new configurations
Machine Operator: uses the GUI
only for monitoring the system
Depending on the kind of operator there are different passwords that protect some
fun
ctions of the GUI.
