Options and modifications:
Analog programming
A Link from pin 12 to pin 6
releases the output, a discon-
nection between these pins
locks it. The link can be made
by switch, relay contact, wire
link, transistor or opto-coupler
output (care for correct polarity
in the last two cases).
Links between pins 15 and 5
and also between 8 and 4 for-
ward the signals of the front
plate potentiometers.
 Output always ON, external input of set values for voltage and
current:
 Output always ON, only set value for voltage is with external
input, current limited to maximum value.
Link between pins 12 and 6 to
release the output.
0 - 10V set value input at pins 8
(voltage) and 15 (current). The
graphic shows the generation
of set values by voltage divider
potentiometers, using the inter-
nal reference at pin 10. Exter-
nal generation of set values is
also possible by digital analog
converters or other signal
sources.
Link between pins 12 and 6 to
release the output.
Input of set value only for volt-
age, pin 15 (set value current)
connected to +10V reference,
limiting the current to the maxi-
mum value by this.

 Read signals in local mode:
These signals can be read out
also when the unit is set to local
mode by the mode switch at the
front plate (switch in position
“local”), so that the values are
set by the front plate control
elements. By analyzing the
status signals (pins 1 and 2) via
threshold switches for example
a good / fail recognising for
isolation tests can be created.
The indication of monitor values
by appropriately calibrated
measuring instruments with 0 -
10V is also always possible,
independently of the mode of
control.
 Master slave circuit 1:
 Master slave circuit 2:
Wipers of the front plate poten-
tiometers (pins 4 and 5) of the
master unit are connected to
the set value inputs of the slave
unit (pins 8 and 15). This allows
a symmetrical control of two
power supplies.
Link between pins 12 and 6 is
necessary to release the output
for the slave unit. (For the mas-
ter unit this depends on the
mode of control.)
The current monitor output (pin
3) of the master is connected to
the current set value input (pin
15) of the slave, while the volt-
age value of the slave is limited
to the maximum value (link
between pins 10 and 8). This
circuit ensures an equal distri-
bution of current with two paral-
lel switched power supplies.
The voltage setting is carried
out at the master power supply
(„local“ - or „remote“- control
possible.)
Link between pins 12 and 6 is
necessary to release the output
for the slave unit. (For the mas-
ter unit this depends on the
mode of control.)
