Safety messages
Carefully read this section before installing or operating this device.
Cautions for installation
WARNING
Installation of the device should be done by the expert from the safety perspective.
In case of the installation in the hazardous area, follow the regulation/guidance of the
explosion-proof.
In case of the installation in the hazardous area, select the explosion-protected apparatus.
Do not use the non-explosion-protected apparatus in the hazardous area.
Install the device in the environment where the following is within in the specifications
listed in the specification sheet.
• Ambient temperature, process fluid temperature
• Process fluid pressure
• Humidity
• Vibration
• Power supply voltage
Environment which exceeds the specifications may cause fire or device damage and it may
cause injury.
CAUTION
DO NOT use the installed device as foot hold. It may cause the damage of the device.
DO NOT hit the glass of the device by tools. It may cause the damage of the device.
Install the device in a location with an ambient temperature of -25 °C to 60°C (-13 °F to
140 °F) and an ambient humidity of 5 to 100% RH to prevent device malfunction or output
errors.
DO NOT install the device near high-current power lines, motors, or transformers to pre-
vent damage from electromagnetic induction, which can cause device malfunction or
output errors.
DO NOT use the device to ground a welder. It can damage the device.
Be sure to ground the welding power transformer when welding near the device to avoid
output errors.
DO NOT install the device in the severe vibration area or in corrosive environment. It may
damage the device, or cause the fume of the device.
DO NOT install the device on the bridge or deck of the ship.
DO NOT install the device on in the severe vibration area on the ship.
Be sure to use the metal conduit for the cables between the remote style transmitter and
flowtube.
Be sure to install the flowtube with a distance of 500mm minimum from the other flow-
tube. Magnetic field generated by a flowtube may affect the other flowtube and it may
cause the output errors.
DO NOT install the device in a location subject to direct sunlight, wind, rain, severe vibra-
tion, or in a highly corrosive atmosphere. The transmitter and flowtube can be damaged.

iii
Cautions for wiring
WARNING
DO NOT wire with wet hands. DO NOT wire while the circuit is alive. It may cause electrical
shock.
ELECTRIC SHOCK HAZARD! Turn the power supply OFF before opening the transmitter
cover.
Wiring of the device should be done by the expert from safety perspective.
Wire the cables to the correct terminal. Incorrect wiring may damage the device or cause
the fume of the device.
Connect the correct power supply. Incorrect power supply may damage the device or
cause the fume of the device.
CAUTION
Be sure to properly ground the device. Improper grounding may cause the output errors
DO NOT give impact to the device. It may cause the damage of the device.
Be sure to use the power supply with the overcurrent protection function.
Be sure proper wiring. Incorrect wiring may cause the damage of the device.
Be sure to properly tighten the terminal cover on the terminal box so that water does not
penetrate in the terminal.
DO NOT connect AC power supply to the DC power supply model. The wrong power sup-
ply damages the device.
Turn off the Fieldbus power supply before connecting the Fieldbus cable to the transmit-
ter. The transmitter or the Fieldbus power supply can be damaged. This type of damage is
not covered by Azbil Corporation’s warranty.
Be sure to plug all unused conduit connections with a water tight plug.
In case that a remote model is installed in a ship, the cables between the transmitter and
flowtube must be covered with a flexible metal conduit.
Switch the control equipment to manual control before terminating the device opera-
tion and shutting off the output to the control equipment. This action prevents the power
shut-off from directly affecting the control equipment.

1. Introduction
This chapter contains an overview of the model MGG14C MagneW PLUS+ Flowmeter
and F Fieldbus system. It describes available configurations and provides
definitions for all the major parts of the transmitter.
MagneW PLUS+ Flowmeter
Thank you for purchasing the Azbil Corporation model MGG14C MagneW PLUS+
Flowmeter This system features:
• Advanced multi-variable capacity
• Digital panel display
• Intuitive, versatile operator interface with large characters and backlit liquid crystal
display
• I/O Capacity
• Flexible digital communication using the F Fieldbus
1.1 System configuration
The model MGG14C MagneW PLUS+ Flowmeter consists of a flowtube and a transmitter
which operate on the principles of Faraday’s law. The flowmeter is available in two
configurations:
Integral – The transmitter is mounted directly on the flowtube and they are installed as an
integrated unit on the fluid pipe.
Remote – The transmitter and flowtube are installed separately and connected together
via cables

1.2 Foundation Fieldbus
The F Fieldbus provides communications and programmability for a single or
multiple flowmeter system. Some features of the fieldbus include:
• Complies with F Fieldbus H1 (31.25 kbps voltage mode bus)
specifications.
• Supports the standard Analog Input (AI) function block.
• Is an externally powered device – AC and DC powered models available.
• Comes with Enhanced Device Description (EDD) files and a Capability File (CF) for
automatic configuration.
The following figure shows a system in which the flow rate is output with a F

How to operate the infrared touch sensor
For best results, approach the key from below and completely cover the circle. Then move
your finger straight down to its original position. These motions ensure correct operation.
Moving sideways across the keys can accidentally activate the wrong control.

Local user interface operation
The following table describes the functions available in each mode.
Display MEASURING MODE
Other than MEASURING MODE
MEASURING MODE This is the normal operational mode and indicates the measuring
status.
Each time the MEASURING MODE is selected, data is written into
memory. Settings entered in other modes are held in temporary
memory for two minutes, but will return to the previously saved
value unless the MEASURING MODE is selected to save the data.
The only exception is the counter, which is always saved into memory
immediately.
BASIC SETUP MODE This mode is used to change data settings that must be recorded or
changed frequently. These settings include:
TAG NO.
Damping time constant
Auto zero
Detector data
MAINTENANCE MODE This mode is used when adjustment or verification is required for
regular maintenance of the system or when troubleshooting the
system. This mode includes:
Shipping information
Output adjustment
Gain adjustment
This mode is further divided into the following two modes:
OUTPUT CHECK MODE
CALIBRATION MODE
ADVANCED MODE This mode is used to apply some specific noise immunity functions.
This mode includes:
Damping
Manual zero
Averaging
Auto spike Cut
Coefficient
Drop out
Low-flow cut off
Flow direction change
