Fault displays
For faults, causes and remedies, see the “Fault/warning message”
flow diagram in chapter 11.3 "Acknowledge fault" on page 122 and
the following tables. The first column of the table lists the code num-
bers displayed in the event of a fault.
NOTICE:
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):
Error type Description
Priority

A fault exists; the pump stops immediately. The
fault must be acknowledged at the pump.
