This submenu set the trip delay time. In case, the trip trigger value (voltage or current) is exceeded for a longer period
than
, contacts 11-14 will close and 11-12 will open.
Here, the threshold for an alarm can be set. The threshold can be set in a range of 0,2 – 20 V for voltage and 20 mA – 5
A for current

. It is also possible to set the threshold by a percent value, which refers to the related nominal range of
current or voltage. In factory setting, the absolute value has to be set.
Attention: This value is adapted automatically by subsequent changes of the transformer ratio.
The input can be changed to percent in menu
under
.
Sets the delay time for alarm. In case, the alarm trigger value (voltage or current) is exceeded for a longer period than
, the contacts 21-24 will close and 21-22 will open.
The trip relay output can be configured as either latch able or non-latch able output.
The trip relay goes back to inactive state as soon as the trip value falls below the adjusted threshold.
The trip relay remains in active state even when the trip value falls below the adjusted threshold. To
reset the relay, push the Button
for 3 sec. After a brownout, the relay falls back into the state before
the brownout.

When using a VT / CT the set thresholds are multiplied by the adjusted transformer ratio.
