What does alarm code 36 on Siemens Measuring Instruments mean?
If your Siemens Measuring Instruments display shows no flow and the measured sound velocity is 0 m/s, accompanied by alarm code 36, it indicates that the pipe dimensions are too small for the selected sensor size or frequency. Verify the pipe dimensions, fluid selection, and sensor selection. The application may not be suitable for the purchased sensor size.
What to do if Siemens Sitrans F indicates flow with no flow in pipe?
If the Siemens Measuring Instruments indicates flow even when there is no flow in the pipe, ensure that the measuring pipe is full of liquid and select the empty pipe limit.
What does alarm code 7 mean on Siemens Measuring Instruments?
If the display shows active flow on your Siemens Measuring Instruments with Alarm code 7, it could be because the measured transit-time (sound velocity) is outside the allowed range for the entered sensor spacing. If your application involves multiple fluid compositions that may experience a significant variation in sound velocity, ensure that the sensor setup wizard is performed using the nominal fluid sound velocity. Also, optimal performance is achieved when the sensors are spaced correctly based on the actual fluid sound velocity, so perform the sensor setup wizard again using the initially measured sound velocity as the expected sound velocity if possible.
Why does Siemens Measuring Instruments show ''?
The Siemens Measuring Instruments displays '' because you requested to output Datalogger data to the printer or Graphics screen when no Datalogger data exists, or at the end of a transmitted file. To solve this, set up the Datalogger.
Why is the flow direction wrong on my Siemens Measuring Instruments?
If the flow rate appears correct, but the sign (flow direction) is wrong on your Siemens Measuring Instruments, first verify that the upstream sensor is connected to the upstream F-connector on the frontend (labeled A). Also, check the flow direction parameter in Setup > Sensor > Flow direction; it might be set to "negative" flow.
What to do if flow exceeds 120% of Q max. in Siemens Measuring Instruments?
If the flow exceeds 120% of Q max on your Siemens Measuring Instruments, check Q max in the Basic Settings.
What does 'Clr Active Memory?' mean on Siemens Sitrans F?
The Siemens Measuring Instruments displays 'Clr Active Memory?' because you pressed and held the key during power-up. This function is used to restore operation if a severe event, like a violent power surge, disrupts the system operation.
What is 'Clr Saved Data?' on Siemens Sitrans F?
The Siemens Measuring Instruments displays 'Clr Saved Data?' only after pressing the in response to 'Clr Active Memory?'. Answering Yes to [Clr Saved Data?] will erase ALL saved data. To invoke in RS-232 serial mode, type @@@ and then press the key.
What should I do after emptying the pipe in Siemens Sitrans F?
After emptying the pipe in Siemens Measuring Instruments, press .
Why is my Siemens Sitrans F showing a process value alarm?
If your Siemens Measuring Instruments device triggers a process value alarm, it means the device has detected deviations from acceptable ambient or process conditions. This could indicate unreliable measured values or larger-than-expected deviations from the set value in the actuators. The solution is to check the ambient temperature and process conditions. If possible, consider relocating the device to a more suitable location.
