0401 PIPEFILL TOUT
08.20 Pump fault word b7
Maximum allowed time for
the Pipefill function
exceeded.
Check the pump system.
Check parameters 81.28….81.35.
0402 MIN FLOW
08.20 Pump fault word b0
Measured flow below
minimum limit.
Check the pump system for reasons
such as leaks that might cause a loss of
measured flow.
Check parameters 81.18….81.24.
0403 MAX FLOW
08.20 Pump fault word b1
Measured flow above
maximum limit.
Check the pump system for reasons that
might cause an increase in measured
flow.
Check parameters 81.18….81.24.
0404 LOW PRESSURE
08.20 Pump fault word b2
Pressure at pump inlet too
low.
Check for a closed valve on the inlet side
of the pump.
Check piping for leaks.
0405 HIGH PRESSURE
08.20 Pump fault word b3
Pressure at pump outlet too
high.
Check piping for blocks.
0406 VERY LOW PRESS
08.20 Pump fault word b4
Pressure at pump inlet too
low.
Check for a closed valve on the inlet side
of the pump.
Check piping for leaks.
0407 VERY HIGH PRESS
08.20 Pump fault word b5
Pressure at pump outlet too
high.
Check piping for blocks.
0408 MAX CLEANINGS
08.20 Pump fault word b6
Maximum number of
cleaning sequences
exceeded (see parameter
group 82 Pump cleaning).
Check for reasons that might have had
an increasing effect on the monitored
signal (parameter 82.09). For example,
increased viscosity of the fluid, or faulty
pump bearings may increase the current
drawn by the motor, and trigger the
cleaning sequence more frequently.
0409 MF MASTER LOST
08.20 Pump fault word b8
The drive cannot detect a
master on the drive-to-drive
link, and is not itself allowed
to become master.
Check that there are drives on the drive-
to-drive link that are allowed to become
master.
Check the wiring of the drive-to-drive link.
0410 MF NO SHARED DATA
08.20 Pump fault word b9
Shared signals not
received.
Check that at least one drive has signal
sharing enabled (parameter 76.12).
Check the status, communication
settings and wiring of the drive that is
sharing its signals.
