Control through a controllable resistance (poti)
3
The power unit can be remote-controlled with an external poti (5 Kohm) 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 1 at one end of the resistance
Connection 2 at the centre sliding contact of the
resistance
Connection 4 at the second end of the resistance
Connections 1 and 4 must not be short-circuited.
2. Switch off the power unit and then connect the remote socket to the rear remote connection. Screw on the external
fastening ring.
3. Switch on the power unit.
4. Put the MODE switch on the rear into the "Remote Ctrl" position. The "REAR CONTROL" dis-
play is lit. The desired output values can now be set through the external poti.
5. Control the complete 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.

6. If this remote control function is no longer required, put the MODE switch to the "Normal" position.
Remote-control output (on/off)
4
The DC output can be turned on and off via the a switching contact.
Proceed as follows for connection:
1. Connect the connecting cables of the remote sockets as illustrated.
2. Contact connections 4 and 5 with an isolated switching contact.
When the output is turned off, the status displays "C.V." (4) and "C.C." (5) will flash. The display will then show the
current settings of the output voltage (2) and the output current (3).
3. When the output is turned off, you can set the output values with the controls for voltage (7) and current limiting (8).
Voltage setting "I":
Connection 1 at one end of the resistance
Connection 3 at the centre sliding contact of the
resistance
Connection 4 at the second end of the resistance
