11 Faults, causes and remedies
Have faults remedied by qualified personnel only! Observe the
safety instructions in chapter 10 “Maintenance” on page 112.
• If the malfunction cannot be rectified, consult a specialist techni-
cian or the nearest customer service centre or representative
office.
Fault indications For faults, their causes and remedies, see the “Fault/warning mes-
sage” flow diagram in chapter 11.3 “Acknowledge fault” on page 122
and the following tables. The first column of the table lists the code
numbers displayed in the event of a fault.
NOTE:
If the cause of the fault no longer exists, some faults resolve them-
selves automatically.
Legend The following types of errors can occur with differing priorities
(1 = lowest priority; 6 = highest priority):
11.1 Mechanical faults
Error type Description Priority
A A fault exists; the pump stops immediately.
The fault must be acknowledged at the pump. 6
B A fault exists; the pump stops immediately.
The counter is increased and a timer counts
down. After the 6th fault, this becomes a def-
inite fault and has to be acknowledged at the
pump. 5
C A fault exists; the pump stops immediately. If
the error exists for more than 5 min, the coun-
ter is increased. After the 6th fault, this
becomes a definite fault and has to be
acknowledged at the pump. Otherwise the
pump restarts automatically. 4
D Like error type A, but error type A has a higher
priority than error type D. 3
E Emergency operation: warning with emer-
gency operation speed and activated SSM 2
F Warning – pump continues to turn 1
