The air nucleation dispense
button was pressed on the
home run screen and a
dispense occurred
The air nucleation dispense
button was pressed on the
home run screen and a
dispense occurred
Pump is unable to deliver
the desired flow rate
The flow rate requested by
the recirculation exceeded
the max flow rate (26 cycle
per pump)
The flow rate requested by
the recipe exceeded the
max flow rate (26 cycle per
pump)
The flow rate requested by
the purge exceeded the max
flow rate (26 cycle per
pump)
Solution
Verify CAN cable is plugged in
Remove and reconnect CAN
cable, taking care not to cross
thread the connector nut
Verify CAN cable is plugged in
Remove and reconnect CAN
cable, taking care not to cross
thread the connector nut
Verify fieldbus cable is properly
connected
Verify host is communicating
Verify fieldbus cable is properly
connected.
Verify host is communicating.
No action necessary if desired. If
not desired, press the button on
the run screen again to enable
the air nucleation during
dispensing
No action necessary if desired. If
not desired, press the button on
the run screen again to enable
the motor during dispensing
Reduce flow rate.
Increase pump sizes.
Measure line voltage. Low line
voltage may reduce maximum
operating flow rate.
Reduce the flow rate so that the
recirculation flow rate is below
the max flow rate
Reduce the flow rate so that the
recipe flow rate is below the max
flow rate
Reduce the flow rate so that the
purge flow rate is below the max
flow rate
