Using the power supply
U> Default: U
Nom
= { U<… U
ovp
}
Tu> Default: 100ms
= { 0…99:59h}
This is slightly different from the OVP (see above). Here the
voltage is also supervised, but it is notied with either an alarm,
a warning or a signal and after a denable 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 dened 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 notied 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 notied after the response time Tu<.
The notication 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 notied 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
I thresholds +
The menu page I thresholds lets you congure 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 notication 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 notied and remains until it is acknowledged and
not persistent anymore.
I< Signal: Undercurrent
