Resetting the device to factory defaults
NOTICE
Previous settings
If you reset, all the settings you have made will be overwritten by factory defaults.
NOTICE
Inadvertent reset
An inadvertent reset can cause disturbances and failures in a configured network with
further consequences.
Requirement
●
The device is in operation.
●
The function "Restore Factory Defaults" is enabled for the "SELECT / SET" button.
Note
Reset despite disabled "SELECT/SET" button
If you have disabled the "Restore Factory Defaults" function for the "SELECT/SET" button in
the configuration, this does not apply during the startup phase, see section "Restoring the
factory settings (Page 80)".
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 operation, follow the steps below:
1.
Switch to display mode A.
Display mode A is active when the LEDs "DM1" and "DM2" are off.
When the LEDs "DM1" and "DM2" are lit or flashing, you need to press the
"SELECT/SET" button several times briefly until the "DM1" and "DM2" LEDs are off.
If you do not press the "SELECT/SET" button for longer than 1 minute, the device
automatically switches to display mode A.
2.
Hold down the "SELECT/SET" button for 12 seconds.
After 9 seconds, the "DM1" and "DM2" LEDs start to flash for 3 seconds. At the same
time, the port LEDs light up one after the other.
If you release the button before the 12 seconds have elapsed, the reset is canceled.
Enabling and disabling the button
In the configuration, you can enable or disable the button function.
