2. External Voltage Programming using a resistor. The resistance coefficient for remote voltage
programming is 5k ohms/100% of rated output voltage with respect to the (ISO VP/IP RTN),
pin 6. The programming current from pin 13 (VP RES) is 1 milliamp through a 5 V DC supply.
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 5-2
for connection requirements.
From the CONTROL menu, set the VOLTAGE REF to EXTRES

3. External Voltage 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 RPV input proportional to the resistor setting. See Figure 5-2
for connection
requirements.
From the CONTROL menu, set the VOLTAGE REF to EXT5V.
