Why is the measured-value reading fluctuating on my Endress+Hauser Measuring Instruments device when the flow is steady?
If the measured-value reading fluctuates on your Endress+Hauser Measuring Instruments device despite a steady flow, here's what you can do: 1. Ensure proper grounding and potential equalization. 2. Check the fluid for any presence of gas bubbles. 3. Increase the value in the "SYSTEM DAMPING" function.
What to do if Endress+Hauser Proline Promag 50 shows reading when fluid is still?
If your Endress+Hauser Measuring Instruments display shows a measured-value reading even when the fluid is at a standstill and the measuring tube is full, take these steps: 1. Ensure proper grounding and potential equalization. 2. Check the fluid for the presence of gas bubbles. 3. Activate the "LOW FLOW CUTOFF" function by entering or increasing the value for the switching point.
Why are flow values negative on Endress+Hauser Proline Promag 50 with forward flow?
If the flow values on your Endress+Hauser Measuring Instruments are negative, even though the fluid is flowing forwards through the pipe, here's what you can do: 1. For the remote version: switch off the power supply and check the wiring. If necessary, reverse the connections at terminals 41 and 42. 2. Change the setting in the "INSTALLATION DIRECTION SENSOR" function accordingly.
How to fix measured-value reading on Endress+Hauser Proline Promag 50 when tube is empty?
If your Endress+Hauser Measuring Instruments display shows a measured-value reading even when the measuring tube is empty, consider the following: 1. Perform empty-pipe/full-pipe adjustment and then switch on Empty Pipe detection. 2. For the remote version: Check the terminals of the EPD cable. 3. Fill the measuring tube.
How to change language on Endress+Hauser Proline Promag 50 display?
If the display texts on your Endress+Hauser Measuring Instruments are in a foreign language, switch off the power supply. Then, press and hold down both OS buttons while switching the measuring device back on. The display text will appear in English (default) and will be displayed at maximum contrast.
Why is the current output signal always 4 mA on my Endress+Hauser Proline Promag 50?
If the current output signal from your Endress+Hauser Measuring Instruments is consistently 4 mA, regardless of the flow signal, here’s what you should do: 1. Select the "BUS ADDRESS" function and change the setting to "0". 2. If the value for creepage is too high, reduce the value in the "LOW FLOW CUTOFF" function.
What does error 401-463 mean on Endress+Hauser Measuring Instruments?
If your Endress+Hauser Measuring Instruments displays error numbers between 401 and 463, it indicates that the measuring tube is partially filled or empty. To resolve this: 1. Check the process conditions of the plant. 2. Fill the measuring tube. If the error is due to EPD calibration not being possible because the fluid's conductivity is either too low or too high, the EPD function cannot be used with fluids of this nature. If the EPD calibration values for empty pipe and full pipe are identical and therefore incorrect, repeat calibration, making sure procedure is correct.
What to do if Endress+Hauser Proline Promag 50 Measuring Instruments has no display but output signals are present?
If there is no display visible but output signals are present on your Endress+Hauser Measuring Instruments, here’s what you can check: 1. Ensure that the ribbon-cable connector of the display module is correctly plugged into the amplifier board. 2. If the issue persists, the display module or measuring electronics might be defective, and you may need to order spare parts.
How to troubleshoot no display and output on Endress+Hauser Measuring Instruments?
If there is no display visible and no output signals present on your Endress+Hauser Measuring Instruments, here’s what you can check: 1. Check the supply voltage at terminals 1 and 2. 2. Check the power line fuse. For 85 to 260 V AC, use a 0.8 A slow-blow / 250 V fuse. For 20 to 55 V AC / 16 to 62 V DC, use a 2 A slow-blow / 250 V fuse. 3. If the issue persists, the measuring electronics might be defective, and you may need to order spare parts.
Why is there no signal at the output of my Endress+Hauser Measuring Instruments?
If a measured value is indicated on your Endress+Hauser Measuring Instruments, but there is no signal at the current or pulse output, the electronics board may be defective, and you may need to order spare parts.
