Description of the device
3.3 SELECT / SET button
Defining the fault mask
Using the fault mask, you specify an individual "good status" for the connected ports and the
power supply. Deviations from this status are displayed as errors/faults.
You configure newly plugged-in connections in the configuration.
To define the fault mask, follow the steps below:
1. Switch to display mode D.
Display mode D is active if the "DM1" and "DM2" LEDs are lit green..
If another display mode is active, you will need to press the "SET/SELECT" button
repeatedly until the "DM1" and "DM2" LEDs are lit green.
2. Hold down the "SELECT/SET" button for 5 seconds.
After 2 seconds,the "DM1" and "DM2" LEDs start to flash for 3 seconds. At the same
time, the port LEDs go on one after the other.
After you have held down the button for 5 seconds, the current settings are stored as the
"good status".
If you release the button before the 5 seconds have elapsed, the previous fault mask will
be retained.

repeatedly until the "DM1" LED is lit green and the "DM2" LED is off.
