1.1Using the Magnetic Flowmeter Safely
(1) 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.
•The magnetic flowmeter must be installed within the specification conditions.
•The magnetic flowmeter is a heavy instrument. Be careful that no damage is caused to personnel through accidentally dropping it, or by exerting excessive force on the magnetic flowmeter. When moving the magnetic flowmeter, always use a trolley and have at least two people carry it.
•When the magnetic flowmeter is processing hot fluids, the instrument itself may become extremely hot. Take sufficient care not to get burnt.
•Where the fluid being processed is a toxic substance, avoid contact with the fluid and avoid inhaling any residual gas, even after the instrument has been taken off the piping line for maintenance and so forth.
•Do not apply excessive weight, for example, a person sttepping on the magnetic flowmeter.
•All procedures relating to installation must comply with the electrical code of the country where it is used.
(2) Wiring
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.
•When connecting the wiring, check that the supply voltage is within the range of the voltage specified for this instrument before connecting the power cable. In addition, check that no voltage is applied to the power cable before connecting the wiring.
•The protective grounding must be connected
securely at the terminal with the 
mark to avoid danger to personnel.
1. INTRODUCTION
(3) Operation
WARNING
•When opening the cover, wait for more than 10 minutes after turning off the power. Only expert engineer or skilled personnel are permitted to open the cover.
•Do not open the cover in wet weather or humid environment. When the cover is open, stated enclosure protection is not applicable.
•Be sure to set parameters as "Protect" on the write protect function after finish of parameter setting work.
Under extremely rare case, the infra-red switches may respond unexpectedly in such conditions as sticking ball of water or extraneous substances on the surface of display panel glass according to the principle of infra-red switch operation.
Its probability rises in such cases as sticking rain water by storm or other similar situation and washing up work near flowmeter installation place.
Either to illuminate or stop illuminating the infrared switches by the flashlight may cause the mis-reaction.
Refer to Chapter 6 "Menu P: Parameter Protection Items" and section "10.2.3" how to use the write protect function in detail.
(4) Maintenance
WARNING
•Maintenance of the magnetic flowmeter should be performed by the trained personnel having knowledge of safety standard. No operator shall be permitted to perform any operations relating to maintenance.
•When opening the cover, wait for more than 10 minutes after turning off the power.
•Do not open the cover in wet weather or humid environment. When the cover is open, stated enclosure protection is not applicable.
•Always conform to maintenance procedures outlined in this manual. If necessary, contact Yokogawa.
•Care should be taken to prevent the build up of dirt, dust or other substances on the display panel glass or data plate. If these surfaces do get dirty, wipe them clean with a soft dry cloth.

1.2 Warranty
•The terms of this instrument that are guaranteed are described in the quotation. We will make any repairs that may become necessary during the guaranteed term free of charge.
•Please contact our sales office if this instrument requires repair.
•If the instrument is faulty, contact us with concrete details about the problem and the length of time it has been faulty, and state the model and serial number. We would appreciate the inclusion of drawings or additional information.
•The results of our examination will determine whether the meter will be repaired free of charge or on an at-cost basis.
The guarantee will not apply in the following cases:
•Damage due to negligence or insufficient maintenance on the part of the customer.
•Problems or damage resulting from handling, operation or storage that violates the intended use and specifications.
•Problems that result from using or performing maintenance on the instrument in a location that does not comply with the installation location specified by Yokogawa.
•Problems or damage resulting from repairs or modifications not performed by Yokogawa or someone authorized by Yokogawa.
•Problems or damage resulting from inappropriate reinstallation after delivery.
•Problems or damage resulting from disasters such as fires, earthquakes, storms, floods, or lightning strikes and external causes.

1. INTRODUCTION
1.3Combination Remote Flowtubes
IMPORTANT
•The AXFA11 Magnetic Flowmeter Converter should be used in combination with the follow-
ing remote flowtubes:
AXFA11G AXF002 -N to AXF26L -N Contact Yokogawa before using it in combination with flowtubes other than those listed above.
•The model AXF C remote flowtube with optional code JF3 (TIIS flame proof type) cannot be combined with the AXFA11 converter. In this case, use the AXFA14 converter.
•If the converter combined with the AXF magnetic flowmeter remote flowtube is changed from the AXFA11 to AXFA14 or vice versa, the meter factor of the remote flowtube must be readjusted according to its flow calibration.
CAUTION
In case of combination with the explosion proof type remote flowtube (AXF C-N) for
ATEX, FM, and CSA certification, please see the manual IM 01E20D01-01E. The construction of the instrument, installation, external wiring, maintenance, and repair are strictly restricted, and non-observance or negligence of these restriction would result dangerous condition.
