Why is my Siemens Measuring Instruments reading erratic?
If your Siemens Measuring Instruments reading is erratic, with little or no relation to the material level, it could be that the true echo is too weak or the wrong echo is being processed. To resolve this, relocate and/or re-aim the transducer.
What to do if Siemens Measuring Instruments displays EEEE?
If your Siemens Measuring Instruments displays 'EEEE', it means the value is too large to display in 4 or 5 characters. To fix this, select larger Units (P005), or lower Convert Reading (P061).
What to do if Siemens Measuring Instruments displays LOE?
If your Siemens Measuring Instruments displays 'LOE', it indicates a weak or non-existent echo. To resolve this, relocate and/or re-aim the transducer.
Why does Siemens Measuring Instruments reading fluctuate?
If the reading on your Siemens Measuring Instruments fluctuates while the material level is still (or vice versa), it is likely due to incorrect measurement stabilization. You can adjust the Maximum Process Speed (P003) or damping (P704) to correct this.
What does Error and tb:(#) mean on Siemens Measuring Instruments?
If your Siemens Measuring Instruments displays 'Error and tb:(#)', it could be due to several reasons: 1. The wrong transducer is selected (P004). Re-enter the correct transducer type. 2. The transducer is connected in a “two wire” method. Do not tie white and shield together; use all three terminal blocks. 3. The transducer is connected backwards. Reverse the black and white wires on the terminal block.
What to do if Siemens Measuring Instruments reading is fixed?
If the reading on your Siemens Measuring Instruments is fixed regardless of the actual material level, the transducer acoustic beam might be obstructed, the standpipe too narrow, or the transducer ringing (reads over 100%). Try relocating and/or re-aiming the transducer at the material level or object.
What to do if Siemens Measuring Instruments displays Open and tb:(#)?
If your Siemens Measuring Instruments displays 'Open and tb:(#)', it indicates that the transducer is either not connected, the connection is reversed, there is an open circuited transducer cable, or a defective transducer at the indicated terminal block number. Check the connection to the displayed terminal blocks and repair or replace components as necessary.
What to do if Siemens Measuring Instruments displays Short and tb:(#)?
If your Siemens Measuring Instruments displays 'Short and tb:(#)', it means there is a short-circuited transducer cable, or a defective transducer at the indicated terminal block number. Repair or replace as necessary.
Why is my Siemens Measuring Instruments display blank?
If the display of your Siemens Measuring Instruments is blank and the transducer is not pulsing, the cause is likely no power. Check the power supply, wiring, or power fuse.
Why isn't Siemens Measuring Instruments responding to programmer?
If your Siemens Measuring Instruments is not responding to the programmer, it could be due to an obstructed infrared interface or a defective programmer. Check programmer usage: ensure it is 15 cm (6”) from the faceplate, pointed at the upper target.
