Mains supply cable interrupted
E Redundant control unit's power supply
has failed
Redundant control unit's fuse is defective Determine the reason for the tripped fuse
Redundant control unit's device fuse has
tripped
Mains supply cable of the redundant con-
trol unit is interrupted

No maintenance date entered.
- Minimum power consumption of the
pump not reached.
Control unit-pump cable interrupted.
Pump is defective.
- Maximum power consumption of the
pump exceeded, possible impeller block-
age.
E Power contactor does not switch off.
- Power supply has failed.
Miniature fuse of the unit (S1) has
tripped.
Power supply has failed, circuit
breaker has tripped.
Main switch is defective - mains sup-
ply cable interrupted.
E Self-resetting temperature monitoring
or
has tripped.
E NON self-resetting temperature monitor-
ing has tripped.
E Incorrect layout or wiring of the probes
The sensors in the control unit are con-
figured incorrectly
- Phase L2 or L3 is no longer applied.
E Incorrect rotating field of the mains con-
nection.
E Motor protection switch has tripped -
motor protection switch set incorrectly.
Pumping current too high due to faulty or
blocked pump.
Excessive current due to phase failure.
E Hose at the fitting to the immersion pipe
(or submersible pressure switch) or con-
trol unit is leaking.
E Maximum operating cycles exceeded.

E Pump runs too long per pumping opera-
tion.

- Pump runs too frequently within a short
time.
Installation and operating instructions
Remedial measure
Check mains supply cable
None, general power outage
and replace the fuse if necessary
Check the fuse of the redundant control
unit
Check the mains supply cable of the
redundant control unit
Carry out maintenance.
Enter maintenance date.
none - general power outage.
Check fuse.
Check main switch.
Check mains cable. Deliberate switch-
ing off, shut down the control unit
(see "Connect to the mains voltage",
page 38).
Self-resetting - the pump starts again
automatically when the motor has cooled
down. The error message is acknowl-
edged automatically. Replace the pump if
the temperature error occurs frequently.
NON self-resetting - the pump remains
inactive, even after the motor has cooled
down. It is necessary to switch off and
switch on again the control unit. Replace
the pump if the temperature error occurs
frequently.
Functional check as described in the sys-
tem documentation.
Check power supply cable and fuses.
Swap 2 phases of power cable.
Set current value according to pump.
Remove blockage.
Replace pump, if defective. Check
mains for phase failure.
Check tightness of the pressure sensor
system.
Can be acknowledged. Inform customer
service. Error appears after a further 1000
operating cycles.
Check the system design, inform the cus-
tomer service department if necessary.
Check the system design, inform the cus-
tomer service department if necessary.
