• The input REM-SB (remote standby, pin 13) overrides the
pushbutton Output On. It means, the output can not be switched
onbythebuttonifthepindenestheoutputstateas„off“Soit
can be as emergency power off.
• The output VREF can be used to build set values for the set
value inputs VSEL, CSEL and PSEL. For example, if only
current control is required, pin VSEL and PSEL can be bridged
to VREF. CSEL is then either fed by an external voltage (0...5V
or 0...10V) or via a potentiometer between VREF and ground.
Also see next section.
• Putting in set values up to 10V while the 0...5V range is selected
will ignore any voltage above 5V (clipping) and keep the output
value at 100%.
• The grounds of the analogue interface are related to minus
output.

10.2 Example applications
Overview D-Sub socket
Attention! Never connect grounds of the analogue
interface to minus (negative) output of an external
control application (PLC, for example), if that control
application is otherwise connected to the neative pow-
ersupplyoutput(groundloop).Loadcurrentmayow
over the control leads and damage the device!
