Changing the jumpers

There are components on this circuit board, that are sensitive to electrostatic discharges.

For further information, refer to Appendix B, “Icons”.

Range selection (PCD2.W610)

Jumpers, factory settings: A0 ... A3:A3: “V” “V” (voltage)(voltage)

U/B: “B” (bipolar)

Reset select: “mid“ (reset to mid-scale,

i.e. 0 V in bipolar mode)

Ranges depending on application:

Per module: U/B: Unipolar or Bipolar operation

Reset select:Reset select:Reset select: Reset toReset toReset to low- or mid-scale

Rec. setting:Rec. setting: Unipolar →low-scaleUnipolar →low-scale→low-scalelow-scale

Bipolar → mid-scale→ mid-scale mid-scale

Per channel: “V” Voltage output:

0 ... +10 V or -10 V ... +10 V

“C”: Current output: 0 ... 20 mA

Current outputs have been laid out for unipolar mode. Bipolar mode is possible, but

for the negative half of this operation the output is 0 mA.
