The “COMMAND” pot adjusts the Analog command signal sent to the flow controller.  The setting for 

each controller connected to the power supply can be observed. (Depending on how the power supply 

was set up, the display could indicate in flow units or percent of full scale).

The flow controller must be connected to the power source as specified in section 2.6.  In general, a 0 - 

5 VDC command signal proportional to the intended flow (0 Volts = zero flow; 5 Volts = 100% of rated 

flow) must be applied to pin 14 of the DA-15 (15 Volt), Pin 3 of the DE-9 (24 Volt) connector.  A 0 - 5 
VDC signal proportional to the flow rate through the instrument will be present on pin 6 of the DA-15 

(15 Volt), Pin 2 of the DE-9 (24 Volt) connector.  The control mode is selected via pin 8 of the DA-15 
(15 Volt), Pin 6 of the DE-9 (24 Volt) connector.  Apply > 10 Volts for full open, < 0 Volts for closed 

and allow the override to float for flow proportional to the command voltage.  Refer to your power supply 
manual for the specifics of implementing these parameters.
