VOLTCRAFT HPS-11530 Bedienungsanleitung Seite 40

The contacts are assigned as follows:
Contact 1 Internal control voltage + 5 V/DC (<50 mA)
Contact 2 Voltage setting
Contact 3 Current setting
Contact 4 Reference ground ("Ground")
Contact 5 Output on/off
Contact 6 - 8 Not assignedt
Control through external voltage source

The power unit can be remote-controlled with an external voltage source from 0 to 5V/DC throughout the range for
voltage and current.
Proceed as follows for connection:
1. Connect the connecting cables of the remote sockets as illustrated:
Voltage setting "U":
Connection 2 to the plus pole (+) of the external
control voltage
Connection 4 to the minus pole (-) of the external
control voltage
The voltage on the remote control connection must not exceed 5 V.
The connections may not be shorted.
2. Switch off the power unit and then connect the remote socket to the rear remote connection. Screw on the external
fastening ring.
3. Turn the voltage of the external voltage source to 0 V.
4. Switch on the power unit.
5. Put the MODE switch on the rear into the "Remote Ctrl" position. The "REAR CONTROL" dis-
play is lit.
6. The desired output value can now be set through the external voltage source. Control the com-
plete adjustment area for correct function. The output voltage can be monitored in the display.
Short-circuit the rear main output (11, 12) with a sufficiently thick cable for checking the current control (at
least 8 mm ). Control the complete adjustment area for correct function.

7. If this remote control function is no longer required, put the MODE switch to the "Normal" position.
