Code Warning
553 Electronic module is de-
fective.
Additional information about causes and remedy
The pump is running, but cannot provide full power under the circumstances.
Contact service.
555 / Implausible sensor value
557 at analogue input AI1 or
AI2.
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 / Cable break at analogue
558 input AI1 or AI2.
Additional information about causes and remedies:
Cable break detection may lead to substitute operating modes that ensure oper-
ation without the required external value.
Twin-head pump:
If W556 appears in the display of the partner pump without a differential pres-
sure sensor connected, always check the twin-head pump connection as well.
W571 may also be activated, however it is not displayed with the same priority
as W556.
The partner pump without a connected differential pressure sensor interprets it-
self as a single pump due to the missing connection to the main pump. In this
case, it recognises the unconnected differential pressure sensor as a cable break.
560 Incomplete software up-
date.
Additional information about causes and remedy:
Software update was not carried out; pump continues to operate with previous
software version.
561 / Analogue input voltage
562 overloaded (binary or
analogue).
Additional information about causes and remedy:
Binary inputs are impaired. Functions of binary inputs are not available.
