Using the power supply
Output off
Pin „REM-SB" is always operative and does not depend on
the remote mode. It can thus be used to switch off the output
without extra means.
Exception: if LOCAL mode was activated by the user (see sec-
tion 6.9), then the control signals on the analog interface are
completely ignored.
The user has to ensure that the level of this input is held con-
stant.
Note
A digital output of, for example, a PLC may not be able to per-
form the action correctly, because it might not be low-resistive
enough. Therefore: always check the technical specifications
of your external control application.
Remote control of current and voltage
Two potentiometers between VREF and ground, sliders at the
inputs VSEL and CSEL. The power supply can be controlled
as with the rotary knobs on the front and can either operate as
current or voltage source. In compliance with the max. 3 mA
for the VREF output, potentiometers with at least 10 kOhm
have to be used.
The power set value is here, for models with power regulation
feature, tied to VREF and thus 100%.

or
Remote control with power
Similar to the example above, but with adjustable power limit.
Power adjustment only works at models from 1000 W.
