Pin Descriptions
Pin 10:
Alarm Output–: This signal is the output of a solid state switch.
The Alarm Out signal is connected by a solid state switch. When an alarm condition occurs, the
dispenser closes the solid state switch, shorting out the Alarm Out pins.
The Alarm Out signal can be activated by the Input Alarm, Pressure Alarm or Auto Increment Alarm.
The Alarm Options LCD screen is used to allow or disallow any of the alarm conditions from
activating the Alarm Out signal.
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 Alarm Out+ pin to
limit the current through the Alarm Output circuit to less than 100mA.
