Handling the device
Reset conguration
If YES is chosen at the conrmation prompt „Are
you sure?“ all editable parameters are reset to their
default values. With NO chosen, all settings remain
unaltered.
After a conguration reset, the value „U output“ of
the selected voltage proles has to be submitted
once again.
Lock setup
After entering a 4 digit PIN code with the arrow but-
tons, the control panel is locked, except the unlock
button. The four numbers can be 0 - 15, which results
in 16
4
= 65536 combinations. Unlocking is done the
same way, by entering the PIN code again. If the PIN
code is lost, the device can only be accessed again
by doing a „Reset conguration“. See above.
Remind, that a conguration reset will reset all settings
to their default values!
Digital remote control
With the optionally available, digital interface cards
(USB, RS232 or CAN) the device can be completely
remotely controlled and monitored. For details of
features and technical specs see the user manual of
the interface cards.
With CAN, multiple power supplies can be networ-
ked.
Analogue remote control
Set values that control output voltage and current
can be given to set value inputs VSEL and CSEL
with control voltages of 0...10V or 0...5V, depending
on the selected control voltage range (see section
„The setup menu“).
The actual output values of voltage and current are
put out as monitoring voltages to outputs VMON and
CMON with 0...10V or 0....5V, depending on the se-
lected control voltage range (see section „The setup
menu“).
Before controlling the device remotely is has to be
switched to remote control by pin 7 „Remote“. Both
values must be given. If only one of both is going to
be adjusted, the other one can be tied to VREF in
order to be 100%.
Remote control by analogue interface is indicated in
the display with the status text „extern“.
