ATTENTION: You are not allowed to use the universal I/O connections for

You are only allowed to use the universal I/O connections for signaling. You
must never use the signals for controlling the application or for

The SafeZone Mini device has two universal I/O connections (see
Connector on page
63). You can configure these two connections for the
following functions:
• Inactive (factory default setting)
As inputs (it is only possible to select one function per universal I/O
connection):
• Stand-by
• External device monitoring (EDM) (see
• Resetting the restart interlock (see
As outputs (it is possible to select several functions per universal I/O
connection, these functions are linked together using an OR operator):
• Device error
• Contamination error
• Contamination warning
• Second warning field
• Reset required
TIP Other functions that can be configured are dependent on the configuration
of the universal I/O connections. For example, you can only realize a restart
interlock if you configure one of the universal I/Os as an input for resetting
the restart interlock.
The universal I/O connections are configured in the SCD software in the Universal I/O area.
