I/O Integration Diagrams
Before any integration signals can be sent over the I/O
connection(s), the integration inputs to the EFR must be
enabled on Integration Screen 1, and the system must
be in the active state. Once the system ready pin is ON,
the EFR is ready to receive commands from the PLC.
To put the system in the active state, press the
button on the ADM until the ADM LED status turns
green, and “Active” is displayed in the upper left corner
of the display. The system can also be put into the
active state by turning the system enable I/O pin ON.
Once the system is in the active state, dispense com
-
mands can be sent over the I/O pins. This can be seen
in the diagrams shown below.
NOTE:
A 100ms delay is suggested between each I/O
signal.
When the pressure preset pin is ON and the system is in the active state, the system will start the priming feature. If
the system or pressure preset pin turns OFF, the system will stop the priming feature.
