This is slightly different from the OVP (see above). Here the
voltage is also supervised, but it is notified with either an alarm,
a warning or a signal and after a definable delay
Tu>
. The
signal vanishes if the voltage is under the thre-shold for the time
Tu>
. Hence you can supervise overvoltages without getting
an OVP error every time or if you only want to get an alarm if
the overvoltage is persistent longer than defined by
Tu>.
U>
Alarm: Overvoltage
This error shuts down the power output. An alarm has to be ack-
nowledged, before the power output can be switched on again.
U>
Warning: Overvoltage
The error is notified and remains until it is acknowledged and
not persistent anymore.
U>
Signal: Overvoltage
Undervoltage supervision
U<
Default:
0V
=
{ 0…
U>}
Tu<
Default:
100ms
=
{ 0…99:59h}
As soon as the voltage falls below the undervoltage threshold,
the undervoltage is notified after the response time
Tu<
.
The notification vanishes, if the undervoltage limit is exceeded
for the time
Tu<
. This undervoltage error is suppressed for
T
0
=100ms after the power output was switched on.
U<
Alarm: Undervoltage
This error shuts down the power output. An alarm has to be ack-
nowledged, before the power output can be switched on again.
U<
Warning: Undervoltage
The error is notified and remains until it is acknowledged and
not persistent anymore.
U<
Signal: Undervoltage
The analogue interface (IF-A1, optional) can signalise an un-
dervoltage at one of the digital outputs.
7.6.2 Current supervision

The menu page
I thresholds
lets you configure the super-
vision circuits for under- and overcurrent.
Undercurrent supervision
I<
Default:
0A
=
{ 0…
I>}
Ti<
Default:
100ms
=
{ 0…99:59h}
The undercurrent error is signalised after the response time
Ti<
, if the actual value of the current falls below the adjusted
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 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
