Error or Message Probable Cause Solution
Invalid Setup During the Initial Makeup the system
detects invalid transducer spacing,
erroneous liquid pipe parameters, or some
other factor that prevents it from completing
the Initial Makeup.
This may be due to one of the following:

An out-of-range data entry.
 An invalid condition (e.g., overlapping
transducers in Reflect Mode).

In Reflect Mode the flow meter detects that the
pipe wall signal may infringe upon the signal.
 Press <ENTER>, <Up Arrow>, <Down Arrow>,
or <Left Arrow> to abort install routine.
Continue programming other site data in
anticipation of resolving the difficulty later. Call
technical support for help, if necessary.
Low Signal - Press
<ENTER>
During the Initial Makeup the flow meter
decides that the level of the receive signal is
insufficient for proper operation.
Some reasons for low signal are:

Invoking [Install Complete] on an empty pipe.

Coupling compound insufficient; not applied or
evaporated.

A disconnected or broken transducer cable.

The pipe needs to be conditioned at the
mounting location.

Flush out large air bubbles.

The sensor cables are defective or not
connected to the correct channel.

The Set Empty routine performed when pipe
was NOT actually empty.
If you locate and correct the improper condition
immediately, press <ENTER> to resume the
installation procedure. Otherwise, press the <Left
Arrow> to abort the installation and conduct a
thorough investigation.
Detection Fault If it appears that the flow meter cannot
complete an Initial Makeup it means that the
pipe and/or liquid conditions do not permit a
receive signal that meets the flow detection
standards. The system will not operate.
Attempt to improve operating conditions by
reinstalling the sensors at a different spacing
offset, or even at a different location on the pipe.
Switching from Reflect to Direct Mount may solve
the problem. However, operation may not be
possible if there is poor liquid, pipe wall sonic
conductivity or extreme liquid aeration. Call
technical support for help, if necessary.
Note
If you receive a Detection Fault message, it is strongly recommended that the Technical
Service Department ( http://www.automation.siemens.com/partner ) be contacted.
