Adjust settings
6. Now press the “Teach In” button > 0.5 s.
The USi signalises that Sensor 2 is now logged on by the continuously lit yellow
LEDs “OUT” for 1 s.
This is how to logoff Sensor
2:
1. Make sure that there is no supply voltage connected.
2. Keep the “Teach In” button pressed (up until step 4).
3. Connect the supply voltage.
The USi signalises readiness for operation to “Logoff Sensor
2” by slowly
fl
ashing
(1
Hz) the green LED “Power”.
4. Now release the “Teach In” button.
Now the yellow LEDs “OUT
2.1” and “OUT
2.2” are alternately lit. The USi
expects your con
fi
rmation for the logoff 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.
5. Now press the “Teach In” button > 0.5 s.
The USi signalises that Sensor 2 is now logged off by the continuously lit yellow
LEDs “OUT” for 1 s.
6. Disconnect Sensor 2 from the M8 socket “Sensor 2”.
Restore Factory Settings
Sometimes a RESET is faster, if a USi that has previously been assigned param-
eters must be reassigned. A RESET writes over all parameters, restoring the factory
settings (see chapter
Factory Settings
). The USi subsequently restarts and auto-
matically executes a “Teach
In”.
Exception: The settings “Sensor
2 logged on” and “Sensor
2 logged off” are not
included in the parameters. These settings remain untouched during RESET.
The “RESET” function is not available with a USi that is ready for operation.
This is how you perform a RESET:
1. Make sure that there is no supply voltage connected.
2. Keep the “Teach In” button pressed down (up until step 4).
3. Connect the supply voltage.
