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. 16). 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. 17.
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
F009 ●
Pump 1 is stopped if an overcurrent is measured for
a certain period of time (blockage protection).
F008
Overcurrent,
pump 2
F010 ●
Pump 2 is stopped, if an overcurrent is measured for
a certain period of time (blockage protection).
F009
Undercurrent,
pump 1
F011 ●●
Pump 1 is stopped, if an undercurrent is measured for
a certain period of time (dry running protection).
F010
Undercurrent,
pump 2
F012 ●●
Pump 2 is stopped, if an undercurrent is measured for
a certain period of time (dry running protection).
F011
Operating time
exceeded, pump 1
F013 ●●
Pump 1 is stopped if normal operating time of the pump is
exceeded, e.g. due to venting problems of pump housing,
closed discharge valve (forgotten to open it after
service/maintenance), forgotten to switch back to
automatic mode, if ON-OFF-AUTO switch is set to "ON"
for service/maintenance. A subsequent emergency
operation starts and stops the pump automatically until
the controller gets a regular stop signal from sensor. The
controller goes back to normal operation.
F012
Operating time
exceeded, pump 2
F014 ●●
Pump 2 is stopped if normal operating time of the pump is
exceeded, e.g. due to venting problems of pump housing,
closed discharge valve (forgotten to open it after
service/maintenance), forgotten to switch back to
automatic mode, if ON-OFF-AUTO switch is set to "ON"
for service/maintenance. A subsequent emergency
operation starts and stops the pump automatically until
the controller gets a regular stop signal from sensor.
The controller goes back to normal operation.
F013 External fault EXT - ●
An external level switch can be connected to the
controller to give an alarm if 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.
