Remote Resistor Programming Of Output Voltage And Output Current - TDK-Lambda Z10-20 User Manual

6.5 Remote Resistor Programming of Output Voltage and Output Current

For resistive programming, internal current sources, for output voltage and/or output current
control, supply 1mA current through external programming resistors connected between J1-6 &
J1-12 and J1-5 & J1-11, J7 . The voltage across the programming resistors is used as a programming
voltage for the power supply. Resistance of 0~5Kohm or 0~10Kohm can be selected to program
the output voltage and current limit from zero to full scale. A variable resistor can control the
output over the entire range, or a combination of variable resistors and series/parallel resistors
can control the output over restricted portion of the range.
Remote Programming settings as follows:
1. For Resistor Analog Programming wiring refer to Fig.6-2.
2. Short pins J1-1 to J1-7.
3. Press MENU button. MENU (GREEN) LED illuminates. "Set" message appears on Voltage display.
4. Press Voltage Encoder. "Ot" message appears on Voltage Display and "CRR" appears on
the current display.
5. Press on the Voltage Encoder to select programming the Output Voltage, or Press Current
Encoder to select programming of the Output Current.
6. The selected function appears on the Voltage display. Parameter "F. " or "E.O" or "E.re"
appears on the Current display.
7. Rotate and press the Current Encoder on to select "E.re".
8. "Ot" message appears on Voltage Display and "CRR" appears on the current display.
9. Rotate Current Encoder until "r G" appears on the display. Press on the relevant Encoder.
10. "rAG" appears on Voltage display and "5" (5K) or "10" (10K) appears on Current display.
11. Rotate and press the Current Encoder to select the desired programming Voltage range.
12. Press MENU button twice to return display to the previous state. MENU LED turns OFF.
