h) Remote Control Operation "Remote Ctrl"
Through the built-in "Remote control" connection (16), the voltage and current can be set through an external volta-
ge source or an external adjustable resistance (short "poti"). The remote control is connected on the rear "Remote
Control" built-in plug (16). There is a remote socket included for connection.
In remote-controlled operation, the current control path must also be connected, since the output
otherwise switches to the current limitation mode "C.C." and limits the output voltage.
Preparation of the remote control connection.
Turn the lateral screw of the supplied socket and remove the front, black contact socket turning it slightly.
Draw five connecting cables with a conductor cross-section of at least 0.34mm2) through the metal sleeve from the
rear. Carefully solder these cables to the soldering lugs nos.1, 2, 3, 4 and 5 of the black contact socket. Ensure that
no short circuits are created..
The numbers of the soldering lugs are indicated on the black insulator.
Mark the loose ends of the cables with the corresponding contact numbers (1-5) to avoid confusion.
Insert the black contact jack in the reverse order into the metal sleeve and screw them tight.
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
