2077 EFB COMM LOSS
(0x7540)
08.08 Alarm word4 b12
Embedded fieldbus
interface has been taken
into use, and there is a
communication break
between the drive and the
master station.
Check:
• selection of the parameter which
enables/disables EFB communication
(58.01 Protocol ena sel)
• EFB connection at terminal XD2D on
the JCON board
• status of the fieldbus master (online/
offline)
• settings of the communication
supervision function (parameter 58.09
Comm loss action).
2201 PIPEFILL TIMEOUT
08.09 Alarm word5 b0
08.21 Pump alarm word b9
Maximum allowed time for
the Pipefill function
exceeded.
Check the pump system.
Check parameters 81.28….81.35.
2202 MIN FLOW
08.09 Alarm word5 b1
08.21 Pump alarm 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.
2203 MAX FLOW
08.09 Alarm word5 b2
08.21 Pump alarm 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.
2204 LOW PRESSURE
08.09 Alarm word5 b3
08.21 Pump alarm word b2
Pressure at pump inlet too
low.
Check for a closed valve on the inlet side
of the pump.
Check piping for leaks.
2205 HIGH PRESSURE
08.09 Alarm word5 b4
08.21 Pump alarm word b3
Pressure at pump outlet too
high.
Check piping for blocks.
2206 VERY LOW PRESS
08.09 Alarm word5 b5
08.21 Pump alarm word b4
Pressure at pump inlet too
low.
Check for a closed valve on the inlet side
of the pump.
Check piping for leaks.
2207 VERY HIGH PRESS
08.09 Alarm word5 b6
08.21 Pump alarm word b5
Pressure at pump outlet too
high.
Check piping for blocks.
2208 PROFILE HIGH
08.09 Alarm word5 b7
08.21 Pump alarm word b6
Application profile protection
limit exceeded (see
parameters 81.25…81.27).
Check the piping for leaks.
Check the general condition of the
components of the pumping station.
2209 MAX CLEANINGS
08.09 Alarm word5 b8
08.21 Pump alarm word b7
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.
2210 ALL PUMPS INLOCKD
08.09 Alarm word5 b9
08.21 Pump alarm word b10
All interlock signals are off,
indicating no pumps are
available.
Check the interlock settings in parameter
group 78 Pump autochange.
Check that the pumps are switched on.
Check the interlock wiring from the
pumps.
2211 ENERGY LIMIT
08.09 Alarm word5 b10
08.21 Pump alarm word b11
Energy consumption limit
exceeded (see parameter
group 83 Energy
monitoring).
Check for reasons for increased energy
consumption.
