Voltage Initiate Circuit
The Ultra 2400 workstation may be initiated with a 5 to 24 VDC signal across pins 1 and 2. The
signal can be momentary (no less than 0.01 seconds) or maintained. A new cycle will begin once
power is removed and then applied again.
Mechanical Contact Initiate
The Ultra 2400 can be initiated via the closure of mechanical contacts such as a relay or switch
using pins 7 and 8. Closure of the contacts can be momentary (no less than 0.01 seconds) or
maintained. A new cycle will begin once the contacts are opened and then closed again.
End-of-Cycle Feedback Circuit
Upon completion of a dispense cycle, a solid state switch closes and remains closed until the next
dispense cycle. Pins 3 and 4 of this 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, 100mA maximum.
