5. Handling

5.1 Powering the device
The device does not feature a power switch. When
connecting it to mains, it is immediately ready to
work.
After switching mains off the device stores the last
state (selected mode, output condition) in order to
restore it automatically at the next start. Thus it can
continue to work after an interruption like a blackout
etc.
5.2 Adjusting the output voltage
The nominal output voltage is seperated into three
selectable voltage ranges, each approximately 1/3
of the nominal voltage. For details see the „Technical
specifications".
The built-in trimmer is a 10-turn type and the ap-
proximate 10 rotations from left stop to right stop
correspond to the selected range.
5.3 Switching output on or off
The pushbutton „On/Off" is used to switch the power
output on or off, if not inhibited by any error (OVP or
OT) or the device being in remote control. The voltage
set by the trimmer will then be put out immediately.
The output can also be switched off at any time via
pin 8 „Rem-SB" of the analogue interface and then
on again.
Attention! The pin REM-SB overrides the pushbutton
„On/Off".
When the output is switched on, the LED „CC" will
indicate constant current operation (LED is on) or
constant voltage operation (LED is off).
5.4 Remote control
Set values can be put in externally via the pins VSEL
and CSEL and with analogue voltages of 0...10V.
The power output values are put out as monitor si-
gnals VMON and CMON in a range of 0...10V.
In order to control the set values remotely, the „remo-
te" control has to be activated first. This is done by
pulling pin 7 „Remote" to low. If required, one of the
set values can be bridged to the reference voltage
VREF and will thus be 100%.
Remote control is indicated by the LED „External".
For pin assigment of the analogue interface see next
page.
