Configurable functions
Universal I/O connections of
the SafeZone Mini
You are not allowed to use the universal I/O connections for safety-relevant functions!
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 safety-relevant functions.
The SafeZone Mini has two universal I/O connections (see Chapter 6, “Round plug connector SafeZone Mini” on page 40).
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 page 18)
•
Resetting the restart interlock (see page 18)
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
Note
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. Fig. 7 shows a configuration
example.

Stand-by
If, in mobile applications, vehicles are not moved for a time, the OSSDs can be switched to the OFF state and the laser on
the SafeZone Mini can be switched off. In this way the power consumption of the device is reduced.
Recommendation
Use this function if, e.g. you use several vehicles and do not move them for a time.
The SafeZone Mini remains in the stand-by mode as long as the related input information is present.
