Pin 4: EOCF–
End of Cycle Feedback–: This signal is the output of a solid state switch.
Upon completion of a dispense cycle, a solid state switch closes and remains closed until the next dispense cycle.
The End Of Cycle Feedback circuit can be used to signal back to a host computer, start another device in sequence
or initiate other operations that need to be tied into the completion of the dispense cycle.
The circuit is designed to operate between 5 to 24 VDC with a 100 mA maximum current.
NOTE:
A resistor should be placed between the external power source and the EOCF+ pin to limit the current
through the EOCF circuit to less than 100 mA.

Pin 5: PS+
24 VDC Power : This pin will provide 24 VDC, 100 mA power to an external load.
Pin 6: CC Init
Contact Closure Initialization: This pin senses a relay or switch closure. Once a closure is sensed, the dispenser
initiates a dispense cycle depending on the operating mode. An internal 1.2K resistor will limit the Contact Closure
Initiate signal current to 20 mA or less. The contact closure can be momentary or maintained in a steady mode. A
new cycle can be initiated by opening and then closing the contact again.
