Possible cause and action
The internal pump flow restrictor needs to be replaced,
•
see Section 7.4.2 Check the function of the pump flow
restrictors, on page 281.
The cable between a module and the ICU is not
•
connected
Remove the module and make sure that the cable is
connected.
Two similar modules have been added to the instru-
•
ment, for example two Inlet valve A
Remove one of the modules with the same Node ID.
The Node ID for one or more of the modules is incor-
•
rect, for example an Inlet valve A2 has the same
Node ID as Inlet valve A. The instrument then con-
siders them to have the same identity.
Remove Inlet valve A2 and change the Node ID accord-
ing to Section 9.15 Check and change the Node ID of
