Protective grounding (earthing) should be connected as shown in the Operator’s Manual. The MagneW FLEX+/PLUS+ has protective grounding (earthing) terminals in the terminal box and on the external surface of its casing.

An external switch or circuit-breaker must be installed near the MagneW FLEX+/PLUS+ on the power line.

The power line is connected to commercial power. The terminal cover must not be opened when power is on.

The model MGG10C/MGG14C MagneW FLEX+/PLUS+ Flowmeter consists of a detector and a converter which operate on the principles of Faraday’s law. There are two main configurations:

Integral: The converter is mounted directly on the detector and they are installed as an integrated unit on the fluid pipe.

Remote: The converter and detector are installed separately and connected together via cables.

The choice of either an analog output or digital output system configuration depends on whether you want to use the digitally enhanced (DE) communication mode.

Analog output (4 to 20 mA DC output): In analog mode, the flowmeter sends the instantaneous flow rate as a proportional 4 to 20 mA output signal to a controller or a recorder in the control system.

Digital output (DE output): A flowmeter in the DE mode can communicate in a direct digital fashion with Azbil Corporation or Honeywell DCS system. The digital signal can include flow rate, flowmeter database, and self-diagnostics.

Switching output mode: The analog/digital output mode is selectable.

In analog mode, the flowmeter can be configured with or without SFC communications.

WITHOUT the communication function

The DC power supply that transmits the analog output is built into the product. The analog output signal is transmitted directly to the host control system.

• Analog output range: 0.8 to 22.4 mA (-20 to +115%)

• Resistive load: 0 to 600 Ω

WITH HART communication function

The DC power supply that transmits the analog output and HART communication is built into the product.

• Analog output range: 3.2 to 22.4 mA (-5 to +115%)

• Resistive load: 0 to 600 Ω

WITH the communication function (SFC or HART)

When using SFC communications, an external power supply (DC power) and external resistive load (minimum 250 Ω) are required. HART communication is also available with the external power supply and resistive load.

• Analog output range: 3.2 to 22.4 mA (-5 to +115%)

• DC power: 16 to 45V DC

• Maximum value of external resistive load is calculated as: (External power supply for communication – 8.5V) / 0.025

CAUTION: For systems WITH the SFC communication function, failure to install the external power supply and the external resistive load will prevent the analog output from being accepted on the receiving instrument side. Be sure to install the external power supply and the external resistive load as specified.

The converter consists of the following components:

Converter:

• Converts electromotive force by the detector to the flow rate signal.

• Transmits the analog output or the digital output as the flow rate signal.

Data setting device (A):

• Displays the flow rate and the totalized value.

• The Data can be configured through the four infrared sensor keys.

Terminal box (B):

• Encloses the inputs/outputs terminals.

• Equipped with lightning arrestor.

Name plate (C):

• Indicates model numbers, product numbers and the detector factor (EX).

Tag number plate (D):

• Indicates the tag number as specified in the product order.

CAUTION: Do not apply over-voltage that exceeds the following lightning arrestor specification. The converter may be damaged.

• Power supply terminal: series mode 1kV, common mode 2kV

• Input/Output terminal: series mode 1kv, common mode 1kV

If the basic model number is MGG14C, 1/2 NPT wiring connection is selected, and style code is selected as “N”, this device functions as an FM, non-incentive-approved model. The installation standards must be followed.

Grounding CAUTION: ELECTRIC SHOCK HAZARD! Grounding is essential for accurate measurement. The grounding resistance must be less than 100 Ω.

For remote installations, the converter and detector are connected using dedicated cables (Model MGA12W) or commercially available cables. The cables between the detector and converter should be no longer than 300 m (984 ft.), but the actual length depends on the conductivity of the fluid being measured.

Cable Diameters:

• Signal cable: 11.4 mm (0.45 in.), 0.75 mm² (.0011625 sq. in.) or equivalent commercially available cable (CVVS or CEEV, for example).

• Excitation cable: 10.5 mm (0.41 in.), 2 mm² (.0031 sq. in.) or equivalent commercially available cable (CVV, for example).

Note: Strip the conductive tubing (black) down to the ends of the inner shields on the conductive wires for terminals A and B of the signal cable.

Selecting the cable:

• The recommended wiring cable is a 600V vinyl sheath electrical wire CVV (JIS C 3401) with a conductor section of 2 mm² (0.0031 inch²), or a twisted cable with an equivalent or higher capacity.

• Shielded wire is recommended for wiring at locations subject to electromagnetic noise interference.

• Select a sheath material suitable for the cable installation environment (consider ambient temperature, corrosive gas, corrosive fluid, etc.).

• Run the cable into the terminal block through the conduit connection (G1/2 internal thread, CM20 external thread, Pg13.5 or 1/2NPT internal thread). An outer diameter of φ11(0.433 inch) is optimum.

• A crimp terminal (M4 screw) with an insulation sleeve is recommended for the terminal connections.

• The maximum length of the wiring cable is 1500 m (4921 ft). However, the maximum length between converter and detector is 300 m (984 ft).

Wiring the cable:

• Run the wiring away from equipment that may generate noise, such as high-capacity transformers, motors, or power supplies. DO NOT install the cable in the same tray or duct as other power cables. Output errors may result.

• For water proofing and damage prevention of the wire, we recommend cabling work using conduits and ducts. Use a water proof cable gland.

Analog Output Wiring:

The current output wiring method depends on HART or SFC communication. An external power supply is required to communicate with the SFC. Change dip switch settings only after turning the power supply OFF.

• Note: Check and confirm that the polarity of the wiring is correct. Incorrect polarity may cause damage to the equipment.

• In case of not using a communication function, the position of dip switch pins should be set as for HART communication. HART Communication works with the wiring for the SFC communication.

• The communication type (HART or SFC) must be specified when ordering. If changing the communication type, you must: 1) Change the switch position according to the communication type. 2) Change the communication type in the “COM SELECT” screen in the “Shipping Info” screen.

Pulse Output Wiring:

The pulse output is an open collector output. Pay close attention to voltage and polarity when wiring.

• Note: Check and confirm that the polarity of the wiring is correct. Incorrect polarity may cause damage. Use an external power supply that meets the voltage and capacity specifications. Pulse may be output when the power is turned ON or OFF. Pulse output protection circuit causes a voltage drop; some counters may not pick up the pulses due to this. In such a case, turn On S6 switch.

Contact Input Wiring:

Either a semi-conductive contact or a no-voltage contact can be used. The contact input terminals are not available when a 2-contact output model has been selected.

Contact Output Wiring:

Pay close attention to voltage and polarity when wiring for an open collector output.

• Note: Check and confirm that the polarity of the wiring is correct. Incorrect polarity may cause damage. Use an external power supply that meets the voltage and capacity specifications.

Write protection settings control the level at which data confirmation and manipulation are possible. The system has four modes:

• Basic setup mode: used to run the flowmeter on a day-to-day basis.

• Engineering mode: used by those who are responsible for flowmeter configuration.

• Maintenance mode: used when system maintenance is required.

• Advanced mode: used to apply some specific noise immunity functions, and other advanced functions.

Settings are changed by setting the switch positions of the write protection switch on the main card. The following table shows the available levels:

✓ – Both data confirmation and manipulation are possible.

– – Only data confirmation is possible.

X – Neither data confirmation nor manipulation are possible.

To set the write protection level:

1. Remove the four screws holding the display cover to the main body of the converter and remove the cover.

2. Locate the write protection switch.

3. Set the write protection switch positions to the required level of protection.

To set communication via HART:

1. Remove the four screws holding the display cover to the main body of the converter and remove the cover.

2. Locate the communication switch.

3. Make sure that position of the I switch (1-4) are ON and positions of the SFC switch (5-8) are OFF.

Note: Refer to the wiring diagram for current output for the wiring.

To set communication via SFC:

1. Remove the four screws holding the display cover to the main body of the converter and remove the cover.

2. Locate the communication switch.

3. Make sure that position of the I switch (1-4) are OFF and positions of the SFC switch (5-8) are ON.

This function fixes the analog output and latches the display to zero when the detector is empty.

To set the empty detection function:

1. Remove the four screws holding the display cover to the main body of the converter and remove the cover.

2. Locate the empty detection function switch.

3. Set the empty detection function switch positions to the required setting (ON or OFF).

To start operation of the flowmeter:

1. Confirm that the detector is correctly installed on the pipe.

2. Confirm that the wiring between the converter and the detector has been properly completed. In case of using a HART/SFC communication function, verify an appropriate wiring.

3. Begin and then stop fluid flow through the detector so that fluid is present in the detector in a static condition.

4. Confirm that there is no leakage at the flanges of the detector.

5. Apply power to the converter.

6. The start-up display appears seven seconds after the power is ON.

7. Zero the flowmeter using the procedure on page 4-14 of the PDF.

The flowmeter is now on and operational.

To shut down the flowmeter:

CAUTION: Switch the control equipment to manual control before terminating flowmeter operation and shutting off the output to the control equipment. This action prevents the power shut-off from directly affecting the control equipment and causing the valve positioner to malfunction.

1. Switch the control equipment connected to the flowmeter to manual control.

2. Turn off power to the converter.

Table: Touch Sensor key Functions

The flowmeter has five modes of operation. CAUTION: The CALIBRATION MODE and ADVANCED MODE contain adjustments and operations that are very important for proper flow rate measurement. Improper settings in these modes will prevent measurement.

This function adjusts the flowmeter so that the measured flow rate is zero when the fluid is in a static condition inside the detector.

CAUTION:

• Before operating the flowmeter for the first time, be sure to carry out auto zero. Zero adjustment is very important for accurate flow measurement.

• Before performing auto zero calibration, make sure the detector is properly grounded (resistance < 100 Ω), filled with the fluid to be measured, and the fluid is in static condition. Zero adjustment is possible with a flow speed of 0.2 m/s or less, but 0.0 m/s is required for accurate adjustment. If conditions cannot be guaranteed, the auto zero function should be ignored.

Procedure:

1. Enter the BASIC SETUP MODE.

2. Use the UP or DOWN key to cycle through the screens until the AUTO ZERO screen appears.

3. Touch the RIGHT SHIFT key once to move the cursor to READY, indicating the system is ready for zeroing.

6. Use the UP or DOWN key to move to the other screen. Then the excitation current is added to the coil to measure the flow rate.

The model MGZ14 and F1X calibrators can be used to input a simulated signal to check the converter function.

Preparation:

• Calibrator and cables

• Digital voltmeter

• Resister (250 Ω)

Check the converter by following the user’s manual of the calibrator.

CAUTION:

When using the MGZ calibrator (S/W version 1.6 or earlier) with converter models MGG10C-M… or MGG14C-M…, you must connect the cables as indicated in the drawings in the manual. If not, the calibrator may not work properly.

If the X,Y cable from the detector is not connected together with the X,Y cable of the MGZ calibrator, upgrade the S/W version of MGZ from the current version to 1.7 or later.

Critical problems can disrupt flowmeter operation. An error message will appear, and the flowmeter will output the preset fail-safe value. If the problem persists after trying these solutions, contact technical support.

Non-critical problems do not seriously disrupt flowmeter operation; the flowmeter continues to output the flow rate. If the problem persists after trying these solutions, contact technical support.

WARNING: Denotes a potentially hazardous situation, which if not avoided could result in death or serious injury.
