6.4 Description of fault indications
If a fault occurs, the symbol
will be visible, an audible alarm will be given by the buzzer and the fault code will be written by means of
the 14-segment characters in the display. To see the kind of fault, if it is automatically reset and the code is not longer visible, open the
fault log (see fig.
). When you leave the fault log, the symbol
will disappear.
The last 20 faults are stored in the fault log as fault codes. The meaning of the fault codes are described in the table below:

F001
Phase sequence
failure
F001
●
(Only three-phase pumps)
The phase sequence between control board and power supply is
wrong. See fig.
F002
One phase
missing
F002
●
●
(Only three-phase pumps)
One phase is missing.
F003
High liquid level
F003
●
●
The liquid level is high in relation to preset value.
F004
Sensor failure
SENSOR
-
●
●
Sensor signal out of range or lost.
F005
Overtemperature,
pump 1
TEMP
●
●
Motor thermal switches connected to the controller will stop pump 1
in case of overheating.
F006
Overtemperature,
pump 2
TEMP
●
●
Motor thermal switches connected to the controller will stop pump 2
in case of overheating.
F007
Overcurrent,
pump 1
F007
●
Pump 1 is stopped if an overcurrent is measured for a certain period
of time (blockage protection).
F008
Overcurrent,
pump 2
F008
●
Pump 2 is stopped if an overcurrent is measured for a certain period
of time (blockage protection).
F011
Operating time
exceeded, pump
1
F011
●
●
The pump has run for more than the allowed operating time and the
controller has stopped the pump for a defined cool-down period in
order to prevent overheating. The operating time and cool down
period depends on the pump. See duty type on nameplate.
Check that the outlet isolating valve is open.
Check that the non-return valve is functioning. A leaky non-return
valve can allow liquid in the outlet pipe to flow back in to the
collecting tank.
Remove any blockage from the venting system, see fig.
F012
Operating time
exceeded, pump
2
F012

F013
External fault
EXT
-
●
An external level switch can be connected to the controller to give
an alarm when basement outside the lifting station is flooded by
groundwater or water from burst water pipe.
F014
Battery failure
BAT
-
●
●
The battery is empty and must be replaced.
F015
Relay or
contactor does
not open, pump 1
RELAY
●
Pump 1 receives a signal to stop, but does not react. This situation
is detected by current measurement.
F016
Relay or
contactor does
not close, pump 1
RELAY
Pump 1 receives a signal to start, but does not react. This situation
is detected by current measurement.
F017
Relay or
contactor does
not open, pump 2
RELAY
●
Pump 2 receives a signal to stop, but does not react. This situation
is detected by current measurement.
F018
Relay or
contactor does
not close, pump 2
RELAY
Pump 2 receives a signal to start, but does not react. This situation
is detected by current measurement.
F019
Display
communication
failure
Display is
off.
●
Communication failure between the main board and the display. As
the display is off, the fault code can be found via PC tool only.
Check the patch cable RJ45 between the main board and the
display.
F117
F117
●
Communication failure between the main board and the display.
The display is still on and is displaying the fault code F117. Check
the patch cable RJ45 between the main board and the display.
F020
High level alarm
in tank
F020
●
Alarm triggered by the additional float switch inside the tank. The
piezoresistive sensor has failed to detect the start level. The float
switch is triggered and starts a pump for 20 seconds (preset value,
changeable via PC tool).
Check the tank, the level sensor hose and the hose connections for
any air leakage.
The level sensor hose is connected correctly to the pneumatic
coupling underneath the controller when you cannot pull it out
without pressing the locking mechanism.
