Pin Descriptions
Pin 4:
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 100mA 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 100mA.
Pin 5:
24VDC Power Supply+: This pin will provide 24 VDC, 100mA power to an external load.
Pin 6:
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 20mA 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.
