7.6.3 Current supervision
I thresholds +
The menu page
I thresholds
lets you configure the supervi-
sion circuits for under- and overcurrent.
Undercurrent supervision
I<
Default:
0A
=
{ 0… I>}
Ti<
Default:
100ms
=
{ 0…99:99h}
The undercurrent error is signalised after the response time
Ti<
, if the actual value of the current falls below the ad-justed
undercurrent limit. The error notification vanishes if the actual
current has exceeded the threshold again for the time
current has exceeded the threshold again for the time
Ti<
.
This undercurrent error is suppressed for T
0
=100ms after the
power output was switched on.
I<
Alarm: Undercurrent
This error shuts down the power output. An alarm has to be ack-
nowledged, before the power output can be switched on again.
I<
Warning: Undercurrent
The error is notified and remains until it is acknowledged and not
persistent anymore.

Signal: Undercurrent
Overcurrent supervision

The overcurrent error is signalised after the response time
Ti>
,
if the actual value of the current falls below the adjusted over-
current limit. The error notification vanishes if the actual current
has exceeded the threshold again for the time
has exceeded the threshold again for the time

. This
overcurrent error is suppressed for T
0
= 100ms after the output
was switched on.
I>
Alarm: Overcurrent
This error shuts down the power output. An alarm has to be ack-
nowledged, before the power output can be switched on again.
I>
Warning: Overcurrent
The error is notified and remains until it is acknowledged and not
persistent anymore.
I>
Signal: Overcurrent
The analogue interface (IF-A1, optional) can signalise an over-
current or undercurrent at one of the digital outputs.
