Troubleshooting Tips
The following is list of messages that you may encounter along with explanations, and in
some cases, a recommended action. If a problem seems unsolvable, contact your local
Siemens Ultrasonic Flow Representative for expert help (www.siemens.com).
Response to an attempt to save site data when data memory is full. Delete an obsolete
site or clear Datalogger memory to make room for the new data.
Memory read error occurred while accessing the active site data.
Response to an attempt to invoke an operation that requires a channel to be enabled
Enable the channel [Channel Setup
be enabled until its transducers are operating.
Response to pressing the F4 key. Use the F4 function to restore operation if a severe
event (e.g., a violent power surge) disrupts system operation.
Response to pressing the F4 key, then selecting [No] for Clr Saved Data? Yes/No
Response to a request to output Datalogger data to the printer or the Graphics screen
when no Datalogger data exists. Set up the Datalogger.
Prompt to empty the pipe during the Actual MTY procedure. After emptying pipe, press
<ENT>.
Prompt to fill the pipe during the Actual MTY procedure. After filling the pipe, press [ENT].
Response while trying to recall/delete a site setup when no Sites are stored. Press [ENT].
Upon measuring the liquid sonic velocity (Vs), the flowmeter recommends re-spacing the
transducers to improve performance.
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). If selecting Direct
Mode does not resolve, review all site setup and transducer installation choices particu-
larly data entered for the pipe and liquid.
• In Reflect Mode, the flowmeter detects that the pipe wall signal may impinge upon the
liquid signal. Use Direct Mode instead.
Press <ENT>, <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.
During the Initial Makeup, the meter decides that the level of the receive signal is in-
sufficient for proper operation. Some reasons for low signal are:
• Invoking [Install Completed?] 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 Xdcr 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 <ENT> to resume the
installation procedure. Otherwise, press the <Left Arrow> to abort the installation and
conduct a thorough investigation.
If it appears that the 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 stan-
dards. The system will not operate. Attempt to improve operating conditions by reinstall-
ing the transducers 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 or pipe wall sonic conductivity or extreme liquid aeration.
