1st row: Current measured value of current measurement transformer 1
2nd row: Direct current portion and alternating current portion of the meas-
ured residual current of current measurement transformer 1
3rd row: Current measured value of current measurement transformer 2
4th row: Direct current portion and alternating current portion of the meas-
ured residual current of current measurement transformer 2
The measured value that is displayed on the main screen is selected in the configu-
ration menu (menu item “AC current value” in Menu “7.Service”). The following can
be selected:

Alternating current with frequencies up to 2 kHz

Alternating current with frequencies up to 20 kHz

Fundamental oscillation
NOTE
The backlight of the display shuts off automatically if no key is pressed for
more than 10 minutes. If no key is pressed for more than 120 minutes, the
display shuts off. The display or the backlight of the display are reactivated
as soon as a key is pressed.
Response messages are displayed as text messages per channel:
2nd row:
Message regarding exceedance of the parameterized response
threshold of current measurement transformer 1
4th row: Message regarding exceedance of the parameterized response
threshold of current measurement transformer 2
Row 1 and 3 remain unchanged. Only the message with the highest priority is dis-
played.
Error messages are displayed per channel as text messages:
1st row:
Error messages that concern current measurement transformer 1
2nd row: empty
3rd row: Error messages that concern current measurement transformer 2
4th row: empty
In the case of multiple messages that occur at the same time, the message with the
highest priority is displayed per channel. The messages do not require acknowledg-
ment. The “main screen” appears again after correcting the error or eliminating the
fault.
