Pin 10: Alarm Out–
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 100 mA 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 100 mA.
Pin 11: PS+
24 VDC Power : This pin will provide 24 VDC, 100 mA power to an external load.
Pin 12 to Pin 15: PS–
24 VDC Power Supply–: These pins are the 24 VDC power supply reference and return pins.
