Setting the display mode
By pressing the button briefly, you change to the display mode of the LED display. You will
find detailed information on the display modes in the sections ""DM1" and "DM2" LEDs for
the display mode (Page 19)" and "Port P1, P2, ... LEDs for the port status (Page 22)".
Resetting the device to factory defaults
If you reset, all the changes you have made will be overwritten by factory defaults.
To reset the device to the factory defaults, 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.
