About the interface cards
Examples: the input DI2/Rem-SB, which is used to switch
the power output on and off (standby), can be activated with
LOW or HIGH, depending on what has been configured in
the setup.
Example 1: the input shall be pulled to GND by a relay (maker
contact) and switch the power output off. Hence you need
to configure the jumper for DI to „Default level = H" and
use the settings Standby = LOW
ON. The output of the power supply can then be switched
by the relay.
Example : the output shall be shut off by an emergency
circuit. The jumper for DI needs to be set to „Default level
=L" and the setting Standby =
relay with a maker contact to Vcc.
There are, of course, many other possible combinations.
Digital outputs with determined functionality
The digital outputs DO1, DO4, DO5 and DO6 can not be
user-defined in their functionality, but they can invert the
logical output level.
DO1/CV
= { LOW | HIGH }
If LOW has been selected, the output is pulled to GND as
soon as the regulation mode of the power supply is determi-
ned by the set value of voltage (CV operation). If
been selected, the output is pulled to 1...15V.

DO4/Mains OK
= { LOW | HIGH }
If LOW has been selected, the output is pulled to GND as long
as the mains voltage is present. If
the output is pulled to 1...15V.
DO5/Standby
= { LOW | HIGH }
If LOW has been selected, the output is pulled to GND if the
power output of the device is off (standby). If
selected, the output is pulled to 1...15V.
DO6/CC
= { 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
has been selected, the output is pulled to 1...15V.
Digital outputs with user-definable functionality
The digital output DO2, DO3 and DO7 can be configured as
desired and the logical level can be inverted.
DO2
DO3
DO7
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 user's guide of PSI9000).
= trip I Triggered by overstepping of the limits I>
and/or I< (see user's guide of PSI9000).
= trip U+I Triggered by overstepping of the limits U>, U<,
I> and/or I< (see user's guide of PSI9000).
Defining 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.
