557 Implausible sensor value
at analogue input AI1 or
AI2. The configuration
and the present sig-
nal lead to an unus-
able sensor value. Check configuration of the
input and connected
sensor.
Additional information about causes and remedy
Incorrect sensor values may lead to substitute operating modes
that ensure functioning of the pump without the required sensor value.
556 /
558 Cable break at analogue
input AI1 or AI2. The configuration
and the present sig-
nal help identify the
cable break. Check configuration of the
input and connected
sensor.
Additional information about causes and remedy:
Cable break detection may lead to substitute operating modes that ensure
functioning of the pump without the required external value.
560 Incomplete software
update. The software update
was not completed. Software update with new
software bundle is recom-
mended.
Additional information about causes and remedy:
Software update was not carried out; pump continues to operate with previ-
