DLM-E Series and DCS-E Series Isolated Analog Programmer Operation

2.3.7 4-20mA Current Source Programming of Output Voltage

SW1 Switch Settings

SW1-1 ON (1) = 4-20mA

4-20mA

91213 12

1420

Set up for 4-20 mA programming of the output voltage as follows:

1. Set SW1-1, V 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-9 and the return to Pin-25.

3. Connect a jumper from Pin-25 to Pin-12 to connect the 4-20mA current sense resistors

to common.

4. Connect a jumper from Pin 20 to Pin 8 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.
