Sensor Operation "Sense - VOLTCRAFT VSP 1220 Bedienungsanleitung

Sensor operation „sense"
The sensor operation "sense" allows the precise voltage setting directly on the consumer. This reliably
compensates a possible voltage drop via the connection cables. Sensor operation is only possible for
output A.
The current setting controls of output A (12) may not be located in the minimum
position (left stop), otherwise it is not possible to use the entire setting range for
the voltage.
Disconnect consumers connected to output A and turn the power supply off.
On the back of the device, remove the plastic cover of the respective terminal strip (19).
Remove the two shorting bars between the clamps „(+) SENSE OUT" and „(+) SENSE IN" as well as „(-)
SENSE OUT" and „(-) SENSE IN".
Connect the consumer with the corresponding output sockets (14 and 15) on the power supply observ-
ing the right polarity.
Connect the sensor cable from the connection clamps of the consumer with the sensor input on the power
supply observing the right polarity. The positive lead must be connected to the clamp „(+) SENSE IN"
and the negative lead to the clamp „(-) SENSE IN".
Reattach the plastic cover to the terminal strip.
Switch on the mains power supply at the power switch (1). The operating display (2) lights up and the
current and voltage display appears on the display.
Set the parameters according to your specifications as described in the chapter "Commissioning".
Verify again that the output voltage has been set correctly.
Now you can switch on the connected consumer.
For normal operation without remote sensing, the shorting bars must be placed
in again.
When disconnecting the consumer, always disconnect the supply cables first or
turn the laboratory power supply off before disconnecting the sensor cables. If
you do not observe this sequence, the output voltage may rise to maximum and
damage your consumer.
