2.11.1 Programming With External Voltage Sources

The output voltage can be programmed using either a 0-5 Vdc or 0-10 Vdc external voltage

source. To program the output voltage with a 0-5 Vdc source, set switch SW1-3 open (default

factory setting) and remove the jumpers connecting pins 8 to 9 and 20 to 21 on connector J3.

Connect the external source between pins 9 (positive) and 12 (return). Varying the external

voltage from 0-5V will cause the output to vary from 0-100% of rated output.

For programming with a 0-10 Vdc source, close switch SW1-3 and replace the 0-5V source with

a 0-10V source.
