End-of-Cycle Feedback Circuit
The UltimusPlus dispenser can send an End-of-Cycle (EOC) feedback signal to an external source. The 24 VDC
EOC output signal is active low during dispensing across D-Sub connector pins 8 and 14 (DC common). The EOC
feedback can be used by external equipment to acknowledge an active dispense cycle.

Alarm Out Circuit
The UltimusPlus dispenser can alert external devices if it enters an alarm state; this is accomplished by creating a
logic high 24 VDC signal between D-Sub connector pins 7 and 14 (DC Common). The signal remains high as long as
the dispenser is in an alarm state, preventing dispensing.
When a dispenser alarm occurs:
• The dispenser prevents any dispense cycles from occurring
• An red warning box appears on the touchscreen
The dispenser will stay in the alarm state until either of the following occurs:
• The alarm is cleared by touching (or clicking) anywhere on the touchscreen.
• The Clear Alarm I/O is toggled (refer to “Clear Alarm Circuit” on page55).
