8.2 Fault display (active)
An active fault is displayed by
. The upper part of the display will become orange and
displays the fault message.
Depending on the type of fault, the LEDs ALARM 1, ALARM 2 or SERVICE are activated.
In the example below, the insulation resistance is 3 kΩ. Because the measured insulation
value is below the set response insulation resistance value of
R
an
=5 kΩ and the DC offset
voltage response value of 150 V has been exceeded, Alarm 1 and Alarm 2 have been trig-
gered. In addition, information concerning the DC-shift is also displayed.
If several fault messages occur, you can navigate through the faults using the and
buttons.

8.3 Fault display (inactive)
An inactive fault is displayed by

will also be indicated.
This message means that there has been a fault in the past but the device is no longer in
