1. Connect the sensor (ultrasonic transducer) and the unit cable with the Evaluati-
on Unit.
2. Make sure that the plug connectors are
fi
rmly mounted.
3. Connect the supply voltage.
Danger of injury due to electrocution!
Ä
Never disconnect terminals with the power on
Ä
Never unplug plug connections with the power on.
WARNING
Initialisation
After the supply voltage has been connected, the USi immediately begins with
initialisation. The USi tests inter alia the internal hardware, the stored functional pa-
rameters and the connected sensor (ultrasonic transducer). The result of the test is
stored internally in the diagnosis memory.
If the diagnosis memory does not contain error reports, the USi starts its function
immediately – namely independently of the existing functional parameters.
At the
fi
rst initialisation following delivery, the USi starts with the functional parame-
ters preset in the factory, the factory settings (see chapter
Factory Settings
): A sen-
sor in operating mode 1 range and a monitoring range of 200
cm (SP2), at medium
object size and middle measurement frequency. The outputs are preset as normally
open contacts.

The Evaluation Unit expects that at least one sensor (ultrasonic transducer) is con-
nected. If only one sensor (ultrasonic transducer) is used, then this must be con-
nected to “Sensor 1”.
