2. External Current Programming Using Resistance. The resistance coefficient for remote
current programming is 5k ohms/100% rated output with respect to pin 6 (ISO VP/IP RTN).
The programming current from PIN 5 (IP RES) is factory set for 1 milliamp. This yields a
coefficient of 1.0% of rated output current for each 50 ohms. If multiple switches or relays are
used to program different levels, make-before-break contacts are recommended. . See
Figure 5-5 for connection requirements.
From the CONTROL menu, set the CURRENT REF to EXTRES.

4. External Current Programming using an external current source. This is similar to the use of
a voltage source except the available current source is converted to a voltage source by using
an external resistor. If the current source is fixed, a variable resistor will result in a voltage
input to the RPI input proportional to the resister setting. See Figure 5-2
for connection
requirements.
From the CONTROL menu, set the CURRENT REF to EXT10V.
