2.11.7 TROUBLESHOOTING TIPS

The System 1010 has highly reliable circuitry and will provide trouble-free operation within specified
environments. Even a well-crafted precision instrument can fail if exposed to extreme temperature or
vibration conditions during service, storage or transportation. The Diagnostic menu shows how the
system interprets a problem. The test functions and alarm indicators identify "hidden" problems auto-
matically. If a problem seems unsolvable, call our Technical Service Department or your local Siemens
Ultrasonic Flow Representative for expert help.

Flow Computer Messages

Certain actions or conditions invoke messages that may appear as a pop-up window, in the right-hand
column of a given menu cell, or the highlighted prompt line at the top of the display screen. The follow-
ing is a list of messages that you may encounter along with explan-ations, and in some cases, a
recommended action.
MESSAGE
Memory Full!
Memory Corrupted!
Chan Not Setup
Clr Active Memory?
Clr Saved Data?
<EOT>
Empty Pipe-Press [ENT] Prompt to empty the pipe during the Actual MTY procedure. After emptying
Fill Pipe-Press [ENT]
No Sites
Not Installed
Re-space Index
Invalid Setup
(use Direct Mount)
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 Channel Enable Yes]. Note
that a channel cannot 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 Memory?
Response to a request to output datalogger data to the printer or the Graph-
ics screen when no datalogger data exists. Set up the Datalogger.
pipe, press <ENT>.
Prompt to fill the pipe during the Actual MTY procedure. After filling the pipe,
press [ENT] (see paragraph 3.1.3).
Response while trying to recall/delete a site setup when no Sites are stored.
Response to an attempt to access a menu function that is not included.
Upon measuring the liquid sonic velocity (Vs), the meter recommends re-
spacing the transducers to improve performance.
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).
If selecting Direct Mode does not resolve, review all site setup and trans-
ducer installation choices; particularly data entered for the pipe and liquid.
• In Reflect Mode, the flow computer detects that the pipe wall signal may
infringe 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 re-
solving the difficulty later. Call technical support for help if necessary.
