3. INSTALLATION 3. INSTALLATION WARNING Installation of the magnetic flowmeter must be performed by expert engineer or skilled personnel. No operator shall be permitted to perform procedures relating to installation. 3.1 Installation Location IMPORTANT Install the instrument in a location where it is not exposed to direct sunlight. For ambient temperature, refer to Chapter 11 “OUTLINE”. The instrument may be used in an ambient humidity where the RH ranges from 0 to 100%.
3. INSTALLATION 2-inch Pipe Mounting 2-inch pipe Mounting fixture Washer Clamp screw Pass the four clamp screws through the mounting fixture, position it on the 2-inch pipe, and then fasten the AXFA11 in place. F0302.EPS Figure 3.2.2 2-inch Pipe Mounting Panel Mounting Unit: mm (approx. inch) 203 (8.0) Panel cutout Mounting fixture 172 (6.8) R3MAX Washer Screw Clamp screw Fit the AXFA11 into the panel.
4. WIRING 4. WIRING four-core cables are used for wiring. Keep conduits or flexible tubes watertight using sealing tape. • Ground the remote flowtube and the converter separately. • Cover each shield of the signal cable with vinyl tube or vinyl tape to avoid contact between two shields or between a shield and a case. • When waterproof glands or union equipped waterproof glands are used, avoid tightening the glands with an excessive torque. • Be sure to turn power off before opening the cover.
4. WIRING 6 to 12mm (0.24 to 0.47 in.) for optional code EP Nominal Cross Section (Single wire): 0.5 to 2.5 mm2 Nominal Cross Section (Stranded wire): 0.5 to 1.5 mm2 C 90 (3.54) Black Red EX1 EX1 EX2 150 5 (5.9) 8 (0.3) max. 20 (0.8) Crimp Terminal 10.5 (0.4) L (Specified Dimensions) Unit : mm (approx. inch) On the flowtube side EX2 B 90 (3.54) 60 (2.36) C 70 (2.76) (5.9) 8(0.3) max.
4. WIRING (1) When there are no particular optional specifications The wiring port is sealed with a cap (not water-proof) that must be removed before wiring. At this time, handle the wiring port in accordance with the JIS C0920-1982 mentioned above. (2) Wiring using waterproof glands IMPORTANT Plastic gland F0406.EPS To prevent water or condensation from entering the converter housing, waterproof glands are recommended. Do not over-tighten the glands or damage to the cables may result.
4. WIRING 4.4 Wiring Connections 4.4.1 Removing Cover While supporting the front of the cover with your hand, flip the connecting screw protective cover over, and remove the four connecting screws. F0409.EPS Figure 4.4.1 Removing the Front Cover 4.4.2 Terminal Configuration When the cover is removed, the connection terminals will be visible. The terminal configuration labels are attached in the position shown in Figure 4.4.2.
4. WIRING 4.4.4 IMPORTANT DC Power Connection When using DC power as the power supply for the converter, give attention to the following points. Do not wire the terminal without terminal symbols in terminal layout labels. (1) Connecting Power Supply IMPORTANT 4.4.3 Precautions for Wiring of Power Supply Cables Do not connect power supply with reversed polarities. L/+ terminal: connect + N/– terminal: connect – When connecting to the power supply, observe the points below.
4. WIRING 4.4.5 Grounding 4.4.6 CAUTION Wiring the Remote Flowtube with the AXFA11 Converter WARNING Be sure to connect the protective grounding of the AXFA11 with a cable of 2mm2 or larger cross section in oder to avoid electrical shock to the operators and maintenance engineers and to prevent the influence of external noise. Connect the grounding wire to the mark (100 or less). Before wiring, be sure that the power supply for AXFA11 converter has been turned off to prevent an electrical shock.
4. WIRING (4) Connection with the Remote Flowtube (General-Purpose Use, Submersible Type, Size 1100 to 2600 mm (44 to 104 in.)) Connect wiring as shown in the figure below. In case of explosion proof type for CENELEC ATEX, FM, and CSA certification, connect wiring as shown in the figure below. In case of the explosion proof type, the protective grounding of remote flowtube must be connected to a suitable IS grounding system. In that case, (functional grounding terminal) need not be connected.
4. WIRING Pulse Output AXFA11 PULSE OUT IMPORTANT • As this is a transistor contact (insulated type), give attention to proper voltage and polarity when wiring. • Do not apply a voltage larger than 30V DC or a current larger than 0.2A in order to prevent damage to the instrument. • When input filter constant of the electronic counter is large in relation to the pulse width, the signal will decrease and the count will not be accurate.
4. WIRING Status Output / Alarm Output AXFA11 Protective diode AL+ IMPORTANT Load AL- Since this is an isolated transistor output, be careful of voltage and polarity when wiring. Do not apply a voltage larger than 30V DC or a current larger than 0.2A in order to prevent damage to the instrument. This output cannot switch an AC load. To switch an AC load, an intermediate relay must be inserted as shown in Figure 4.4.13 or Figure 4.4.14.

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.
9. ACTUAL OPERATION NOTE The results of M10: Auto Zero Exe can be displayed using M11: Magflow Zero . Alternatively, if the results of the automatic zero adjustment exceed the rated value, the warning 82: Auto Zero Wng will be displayed. 9.1.2 Zero Adjustment via External Status Input This section describes the procedure for zero adjustment via external status input. (For more details regarding external status input, refer to Chapter 6: Parameter Description.

MAINTENANCE 10.1 Components Replacement WARNING • Component replacement and the associated operations must be carried out by expert engineer or skilled personnel and not by operators. • Before opening the cover, it is important to ensure that at least 10 minutes have passed since the power was turned off. Furthermore, opening of the cover must also be carried out by a expert engineer or skilled personnel. Fuse holder F1001.EPS Figure 10.1.

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.
