6.7. Fault codes
A technical failure will be signalled by the pump with a continuous alarm display and
a continuous sound. During this state, the fault code which causes the pump to fail
can be displayed by pressing the key “MODE”.
If the pump was switched OFF after a detected failure, the fault code will be stored
in the configuration of the pump (see index 380 - 389 via ARGUS
service
PC-tool).
The possible fault codes registered in the configuration are listed in the table below:
Fault

We recommend replacing the main board in case a fault code is not included in this
list above.
*
Failure released only if configured with upstream sensor (index 51=Yes).
**
Fault code F_52 may occur after a software update or if peristaltic is manu-
ally turned during service. In this case, turn the pump off then on again and
restart the pump. If a failure free start can be performed, omit this fault
code.
