Operation
Control Modes
The E-Flo iQ system can be controlled locally or
remotely. Pressing the soft key for this icon toggles back
and forth between the two modes. When this icon
is displayed, the pump is controlled in Local mode
through the display. When this icon
the pump is controlled in Remote mode through discrete
I/O or fieldbus protocols.
If the system is in Remote mode, the pump is active, and
there are no errors, dispensing can be controlled by the
Programmable Logic Controller (PLC) or robot through a
fieldbus connection. The ADM goes into PLC Lockout
during this time. While in PLC lockout, the PLC has
complete control. You can change settings if they are
not password protected but cannot perform any other
functions using the ADM.

located above the pump on the Run Home screen
indicate the pump status and whether or not an error is
active on the pump. They represent increasing levels of
readiness and activity.
