Set up for 4-20 mA programming of the output current as follows:
1.
Set SW1-2, I PROG, to ON (1) for 4-20mA programming range.
2. Connect the external programming current source to the ISOLATED ANALOG
PROGRAMMER connector, J4, with the source to Pin-10 and the return to Pin-13.
3. Connect a jumper from Pin-13 to Pin-12 to connect the 4-20mA current sense resistors
to common.
4. Connect a jumper from Pin 23 to Pin 11 to provide the negative 2.5VDC to zero out the
4mA signal generated by internal circuits.
5. Connect Pin-1, ANALOG-CONTROL, of the ISOLATED ANALOG PROGRAMMER
connector, J4, to Pin-2 to enable remote control.
6. Program the other parameters to the desired limit values.
