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
W25:    Right
W26:    Right
W31:     Open
W32:     Left
 
Connect Input signal  between J1-4 (+)  and J1-5 (-)
 
0-1mA
W25:    Left
W26:    Right
W31:     Right
W32:     Open
 
Connect Input signal  between J1-4 (+)  and J1-5 (-)
 
0-50mV
W25:    Open
W26:    Left
W31:     Open
W32:     Right
 
Connect Input signal  between J1-3 (+)  and J1-5 (-)
 
0-10V
W25:    Open
W26:    Left
W31:     Left
W32:     Open
 
Connect Input signal  between J1-3 (+)  and J1-5 (-)
