2.7.3. 

Operation with an External Sensor (External Input) 

In some instances, it might be desirable to use an external sensor to provide process information to the 
control circuitry in a Hastings flow instrument.  For example, you might want to control the pressure in a 
vacuum system by adjusting the rate at which the system is backfilled with a gas. Hastings flow 
controllers have provision for accepting a 0

5 VDC output from an external sensor at pin 13 of the DA-15 

(15 Volt), Pin 1 of the DE-9 (24 Volt) connector. 
 

2.7.3.1.  15 Volt Units 

To activate this feature, the cover of the 
HFC must be removed to gain access to the 
electronics card and move a jumper. For 
the 15 Volt units, J6 is located on the left 
side of the pcb between the span 
potentiometer (R7) and the large D 
connector (J1). In the normal operating 
mode, the jumper covers the left two pins. 
To select an external sensor input, move 
the jumper to the right two pins. This 
swaps the flow input to the controller 
circuit from the flow meter output to pin 

13 of the “DA

-

15”

 connector.  

 

2.7.3.2.  24 Volt Units 

For the 24 Volt units J8 is a six-pin jumper 
block located down and to the right from 
the DC-DC converter.  There are three 
jumpers installed horizontally. The middle 
jumper ties the flow output to the valve 
control circuit and the top jumper ties Pin 
1 of the DE-9 connector to reference 
voltage circuit. Remove both of the upper 
two jumpers and reinstall one jumper 
vertically between the top two pins on the 
right side (see diagram below). This will tie 
Pin 1 of the DE-9 connector to the valve 
control circuit and allow the controller to 
maintain the external process variable 
equal to the desired setpoint. The 5 Volt 
reference is not available in this 
configuration.
