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.
Why Siemens Sitrans F Measuring Instruments shows unstable low signal?
If the Siemens Measuring Instruments shows an unstable low signal, the issue might be due to several factors: pulsating flow, air bubbles in the medium, vibrations, or pump noise. To address this: * Increase the time constant. * Ensure the medium does not contain air bubbles. * Make sure that the sensor is mounted on a rigid frame without vibrations. * Ensure that the pump frequency is different from the resonance frequency of the sensor.
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.
How to disable simulation mode on Siemens Sitrans F Measuring Instruments?
If your Siemens Measuring Instruments shows a simulation or substitute value, it means the output signal temporarily does not represent the actual process because it's based on a simulation value. To resolve this, disable simulation mode via the HMI or engineering system, or try restarting the device.
How to disable manual mode on Siemens Sitrans F?
If your Siemens Measuring Instruments is in manual operation, the output signal is temporarily invalid, possibly frozen, because work is being performed on the device. To fix this, disable manual mode via the HMI or engineering system.
Why Siemens Sitrans F Measuring Instruments displays 'Low Signal - Press '?
The 'Low Signal - Press ' error on your Siemens Measuring Instruments indicates that the receive signal level is insufficient for proper operation during the Initial Makeup. This can be due to several reasons: * Invoking [Install completed?] on an empty pipe. * Insufficient or evaporated coupling compound. * A disconnected or broken sensor cable. * The pipe needs conditioning. * Large air bubbles. * Defective or incorrectly connected sensor cables. * The Set Empty routine was performed when the pipe was not actually empty. If you correct the condition, press to resume the installation. Otherwise, press the to abort and investigate.
How to resolve PulseA overload on Siemens Sitrans F?
If your Siemens Measuring Instruments display shows 'PulseA overload', it means there are incorrect settings for output A. You should change the volume per pulse to a higher value, referring to the technical data on page 98 for pulse selection. Keep in mind that Pulse A is limited to 100Hz. The alarm will remain active until the output pulse rate drops below the maximum.
What to do if Siemens Sitrans F shows measuring pipe empty?
If your Siemens Measuring Instruments indicates that the measuring pipe is empty, ensure that the measuring pipe is full.
