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.
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.
