Current supervision
I thre
The menu page
I thresholds
lets you configure the
supervision 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
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
acknowledged, 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.

Default:

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

Alarm: Overcurrent
This error shuts down the power output. An alarm has to be
acknowledged, 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- or undervoltage at one of the digital outputs.
