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 Supply+: 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.
