About the interface cards
DO6/CC Default: LOW
= { LOW | HIGH }
If LOW has been selected, the output is pulled to GND as
soons as the regulation mode of the power supply is deter-
mined by the set value of current (CC operation). If HIGH
has been selected, the output is pulled to 12...15V.
7.3.5 Digital outputs with user-denable functionality
The digital output DO2, DO3 and DO7 can be congured as
desired and the logical level can be inverted.
DO2 Default: OVP LOW
DO3 Default: OT LOW
DO7 Default: CP LOW
Dening the logical level when triggered/indicated:
= LOW The output is pulled against GND as soon as
the selected function becomes active. The
logical level is inverted, if the condition is not
true.
= HIGH The output is pulled against +15V by a high
resistance resistor as soon as the selected
function is active. The logical level is inverted,
if the condition is not true.
One of the following functions can be assigned to each of
the outputs:
= remote Indicates that the power supply is remotely
controlled via a digital interface card.
= OT Indicates an overtemperature error.
= CP Indicates that the power supply regulated by
the set value of power (CP operation).
= Alarm Indicates that an alarm has happened. The
output of the power supply is automatically
shut down and the alarm can be indicated by
this output.
= trip U Triggered by overstepping of the limits U> and/
or U< (see device instruction manual).
= trip I Triggered by overstepping of the limits I> and/
or I< (see device instruction manual).
For models of PSI 8000 series additionally available:
= trip U+I Triggered by overstepping of the limits U>, U<,
I> and/or I< (see device instruction manual).
= trip Dyn Triggered by step response supervision (see
device instruction manual).
= Fct. runs Signalises a running function (see device
instruction manual).
= Fct. end Signalises a stopped function (see device
instruction manual).
= new Fct. Signalises when a function was set to the start
(see device instruction manual).
= disable Does not signalise a specic ccondition, pin
will be either LOW or HIGH, depending on the
setting.
