8. Place the reference object at the desired distance in the detection
fi
eld.
If the USi recognises the reference object, the green LED “Power” changes from
quick
fl
ashing (5
Hz) to being continuously lit.
9. Press the “Teach
In” button (> 0.5 s), and the USi overwrites the previous switch
point
SP1 with the determined distance to the reference object.
The USi now operates automatically in the operating mode 2 ranges.
10. Check both switch points: Move the reference object toward the USi and back
again. Does a signal change occur at the output when the set switch points are
executed (see yellow LEDs “OUT”)? Does the signal change take place at the
correct distance?
TIP: Omit reference object.
If you set the switch points without the reference
object, the USi automatically saves the
maximum
distance
of 250 cm for switch
point
SP2 and the
minimum
distance
of 1 cm for switch point
SP1.
TIP: Cancel.
After Step 5, cancellation is only possible by
disconnection of the
supply voltage.
Logon/logoff Sensor
2
The USi is preset to one sensor (ultrasonic transducer) on Sensor 1 when supplied.
If a second sensor (ultrasonic transducer) is required, Sensor 2 must be logged on.
Sensor
1 must always remain connected; it may not be logged off.
The “Sensor 2 logon/logoff” function is not available with a USi that is ready for
operation.
This is how to logon Sensor
2:
1. Make sure that there is no supply voltage connected.
2. Connect Sensor 2 to the M8 socket “Sensor 2”.
3. Keep the “Teach In” button pressed down (up until step 5).
4. Connect the supply voltage.
The USi signalises readiness for operation to “Logon Sensor
2” by slowly
fl
ashing
(1
Hz) the green LED "Power".
5. Now release the “Teach In” button.
Now both yellow LEDs “OUT
2.1” and “OUT
2.2” simultaneously
fl
ash slowly
(1 Hz). The USi expects your con
fi
rmation for the logon to Sensor 2 within 10 s.
Note:
If the “Teach
In” button is not pressed, the USi will automatically cancel the
function “Logon/logoff Sensor
2” after a period of 10 s.
