9. ACTUAL OPERATION 9. ACTUAL OPERATION After you have installed the flowtube into the process piping, wired the input/output terminals, set up the required parameters, and performed a pre-operation zero adjustment, the magnetic flowmeter should output an accurate flow signal from its terminals as soon as flow of the fluid to be measured begins. This section describes zero adjustment and the corresponding procedures. 9.
9. ACTUAL OPERATION 9.1.1 Zero Adjustment Using Display Unit Switches This section describes the procedure for zero adjustment using the display unit switches. (For more details regarding setting methods using these switches, refer to Chapter 5: Basic Operating Procedures.) The parameters for zero adjustment are B50/M10: Auto Zero Exe (and either of these can be used to carry out this procedure). For more details regarding these parameters, refer to Chapter 6: Parameter Description.

10. MAINTENANCE 10. MAINTENANCE 10.1 Maintenance 10.2 Setting of Switches WARNING IMPORTANT • Maintenance work must be carried out by the trained personnel having knowledge of safety standard and not by operators. • When opening the cover, wait for more than 10 minutes after turning off the power. Furthermore, opening of the cover must also be carried out by the trained personnel having knowledge of safety standard. • Lifting of display unit is necessary for setting switches.
10. MAINTENANCE 10.2.3 Setting of Write Protect Switch By setting the write protect function to “Protect” it is possible to prevent the overwriting of parameters. Write protection can be carried out using either the hardware switch on the CPU board (i.e., Switch 2) or software parameter settings. If either of these items is set to “Protect”, the overwriting of parameters will be prohibited.
10. MAINTENANCE 10.3 Troubleshooting Although magnetic flowmeters rarely require maintenance, failures may occur when the instrument is not operated correctly. This section describes troubleshooting procedures where the cause of the breakdown is identified through receiver indication. 10.3.1 No Indication START Is an error being displayed? Check the converter display. Is an error being displayed? YES Examine in accordance with Section 6.5: Alarms.
10. MAINTENANCE 10.3.2 Unstable Zero START Investigate whether or not the flowtube is filled with fluid and that it is free of bubbles. *1: When checking for bubbles, it is convenient if there is a gas vent hole on the flowtube’s downstream side. *1 Is the flowtube completely full of fluid? NO Particular care must be taken in the case of horizontal mounting. In order to ensure complete filling of the tube, either adjust the mounting position or switch to vertical mounting.
10. MAINTENANCE 10.3.3 Disagreement Between Indication and Actual Flow START NO Are parameters set correctly? Set the parameters correctly. YES Examine the condition of the fluid in the flowtube, of bubbles, and of grounding. Was zero adjustment carried out correctly? Execute zero adjustment when the flowtube is filled completely with fluid and when the fluid is not moving.
