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 3-1 <3. INSTALLATION> Piping Design Precautions IMPORTANT Design piping correctly, referring to the following to prevent damage to flowtubes and to assure accurate measuring. (1) Location IMPORTANT Install the flowmeter in a location where it is not exposed to direct sunlight.
3-2 <3. INSTALLATION> (5) Precautions for Use of Liquid Sealing Compounds IMPORTANT Care must be taken in using liquid sealing compounds on the piping, as it may have a negative influence on the flow indications by flowing out and covering the surfaces of an electrode or grounding ring. In particular, care must be taken if a liquid sealing compound is used in the case of vertical piping.
<3. INSTALLATION> 3-3 • Mounting orientation IMPORTANT 90 degrees or less If electrodes are perpendicular to the ground, air bubbles near the top or precipitates at the bottom may cause measurement errors. Ensure that the terminal box of a remote flowtube is mounted above the piping to prevent water from entering them. Eye bolt Correct 90 degrees or less Eye plate F0307.ai Incorrect Incorrect Figure 3.2.
3-4 <3. INSTALLATION> • Confirmation of sealing conditions for the flowmeter Confirm that the terminal box screw and wiring ports are well sealed. Equip the conduit piping with drain plugs or waterproof glands to prevent moisture or water from penetrating into the flowmeter through the conduit. • Regular inspections Inspect the sealing conditions as mentioned above, and the inside of the terminal box at least once a year. Also, due to rain, etc.

Mounting Procedure (with optional Grounding Rings GR1 for sizes up to 1000 mm (40 in.)): 1. Handles of the grounding ring have some holes which correspond to outer diameter of each flange type. There are printings near each hole. The printings show types of flange. See the table below. Printing 3-6 <3.

4. 4.1 <4. WIRING> 4-1 WIRING Wiring the Remote Flowtube This section describes the wiring of the remote flowtube only. For information relating to the wiring of the converter, refer to the user’s manual of the AXFA11 Magnetic Flowmeter Remote Converter (IM 01E20C01-01E). WARNING The wiring of the magnetic flowmeter must be performed by expert engineer or skilled personnel. No operator shall be permitted to perform procedures relating to wiring.
<4. WIRING> 4.1.2 Cables CAUTION (1) Dedicated Signal Cable (AXFC) • As crimp terminals A, B, SA, SB and C have their own electrical potentials, securely insulate them so as not to come in contact with one another. • To prevent a shield from coming in contact with another shield or the case, cover each shield with a vinyl tube or wrap it in vinyl tape. Conductors (A and B) Shields (SA and SB) Tape Outer jacket 10.5 (0.413") Shield (C) Insulation Insulation NOTE F0401.ai Figure 4.1.

5. <5. MAINTENANCE> 5-1 MAINTENANCE WARNING • 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. CAUTION • When opening the cover, use a hexagonal wrench (nominal size 3 mm).
5.2 Regular Inspection Items (1) Inspection of moisture-proofing inside the terminal box: Once/year (2) Retightening of piping joint screws: About twice/year (3) Inspection of electrodes and lining (in case of adhesive and/or abrasive fluids, etc.) Determine the period of regular inspection as necessary. 5.
5.4 <5. MAINTENANCE> 5-3 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. 5.4.1 No Indication START Is an error being displayed? Check the converter display. Is an error being displayed? YES Refer to the “Alarm Functions” in the AXFA11.
<5. MAINTENANCE> 5-4 5.4.2 Unstable Zero START Investigate whether or not the flowtube is filled with fluid and that it is free of bubbles. *1 Is the flowtube completely full of fluid? NO *1: When checking for bubbles, it is convenient if there is a gas vent hole on the flowtube’s downstream side. 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.
<5. MAINTENANCE> 5-5 5.4.3 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.
