7.2  Restoring the factory settings 
 
If you reset, all the settings you have made will be overwritten by factory defaults. 
 
NOTICE 
An inadvertent reset can cause disturbances and failures in the configured network. 
Requirement 
The device is in the startup phase. 
 
Reset despite disabled "SELECT/SET" button 
Using the "SELECT/SET" button, you can always reset the device parameters to the 
factory defaults during the startup phase of the device. This applies also if the "Reset 
to Factory Defaults" function was disabled in the configuration. This allows you to reset 
the device to the factory defaults in an emergency. 
If the function has been disabled in the configuration, it is only disabled on completion 
of the startup phase. 
Procedure 
To reset the device to the factory defaults during the startup phase, follow the steps 
below: 
1.  Turn off the power to the device. 
2.  Now press the "SELECT/SET" button and reconnect the power to the device while 
holding down the button. 
3.  Hold down the button until the red error LED "F" stops flashing and is permanently lit. 
4.  Now release the button and wait until the fault LED "F" goes off again. 
5.  The device starts automatically with the factory defaults. 
Restoring the factory defaults during operation 
You can also reset the device to the factory defaults during operation, see section 
"SELECT/SET button (Page 34)".
