To control the MP controllers setpoint with an analog DC signal the MP control must have the "S" option. Units that include the S option include U40 an U42 integrated circuits on the main controller board.
To configure the controller to accept the analog signal to control the voltage setpoint set the following switches and jumpers on the main controller board:
S W I T C H S E T T I N G S
Switch SW2 #3: OFF
Switch SW3 #1 OFF
J U M P E R S E T T I N G S
4-20mA
