NOTICE
Some faults resolve themselves automatically if the cause of the fault is no
longer present.
The following types of errors can occur with differing priorities (1 = lowest priority; 6 =
highest priority):
Error type Description
A A fault is present; the pump stops immediately. The fault
must be acknowledged at the pump.
B A fault is present; the pump stops immediately. The
counter is increased and a timer counts down. After the
6th error event, the error becomes a final fault. The fault
must be acknowledged at the pump.
C A fault is present; the pump stops immediately. If the fault
persists for more than 5 minutes, the counter is increased.
After the 6th error event, the error becomes a final fault.
The fault must be acknowledged at the pump. Otherwise
the pump restarts automatically.
D The same as fault type A, but with lower priority.
