APPENDIX A - I/O CONNECTOR PIN DESCRIPTIONS
Pin 1: VI+
Voltage Initiate+: This pin is the positive side of a Voltage Initiate signal.
Pin 2: VI–
Voltage Initiate–: This pin is the return of the Voltage Initiate signal.
The Voltage Initiate signal will trigger a dispense cycle when a 5 to 24 VDC signal appears across these
pins. An internal 1.2K resistor will limit the Voltage Initiate signal current to 20mA or less. The signal can
be momentary (no less than 10ms) or maintained. A new dispense cycle will begin once the 5 to 24 VDC
signal is removed and then applied again.
Pin 3: EOCF+
End of Cycle Feedback+: This is the positive input signal for the End of Cycle Feedback solid state
switch.
