3. Grounding (Earthing)

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.

4. Equipment operation

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

The MGG10C/MGG14C MagneW FLEX+/PLUS+ Flowmeter consists of a detector and a converter. It is available in 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 via cables.

You can choose between an analog output or a digital output system configuration.

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): In DE mode, the flowmeter can communicate in a direct digital fashion with an 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 communication functions.

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) using an external power supply:

When using SFC communications or HART with an external power supply, an external DC power supply and an external resistive load (minimum 250 Ω) are required.

• 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 them as specified.

The converter consists of the following components:

Converter: Converts the electromotive force from the detector to a flow rate signal and transmits it as an analog or digital output.

Data setting device (A): Displays the flow rate and totalized value. Data can be configured through the four infrared sensor keys.

Terminal box (B): Encloses the inputs/outputs terminals and is equipped with a lightning arrestor.

Name plate (C): Indicates model numbers, product numbers, and the detector factor (EX).

Tag number plate (D): Indicates the tag number specified in the product order.

CAUTION: Do not apply over-voltage that exceeds the following lightning arrestor specifications, as 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 the style code is “N”, the device functions as an FM, non-incentive approved model. The following installation standards must be followed:

WARNING: ELECTRIC SHOCK HAZARD!

The AC POWER and XY terminals of the converter terminal block are high-voltage terminals. Turn off the power supply before connecting cables to these terminals. When connecting, lift the protective cover marked “WARNING”. After connecting, return the protective cover to its original position.

CAUTION:

• Use electrical tube and duct to prevent water entry and protect the cable from external damage.

• Use a waterproof gland at the conduit connection to prevent water entry inside the terminal box and prevent output errors.

• Turn off the power supply before connecting cables to the converter. Damage from connecting with power on is not covered by the warranty.

• Plug all unused conduit connections with a water-tight plug.

• If a remote model is installed on a ship, the cables between the converter and detector must be covered with a flexible metal conduit.

• When connecting wires, check the polarity of each wire. Incorrect polarity may damage the equipment.

• After trial operation or inspection, ensure the wiring is returned to the correct configuration for normal use.

The following cables are required:

• Analog output cable

• Pulse output cable

• Contact input/output cable

The terminal descriptions are as follows:

Note: In case of DC24V and DC110V power supply, the symbol of the “L” and “N” of the power supply become “+” and “–”.

To wire a remote system, the following cables are required:

• Signal cable

• Excitation cable

• Analog output cable

• Pulse output cable

• Contact input/output cable

The terminal connections depend on whether you have a 1-contact, 2-contact input, or 2-contact output configuration. The general terminal descriptions are as follows:

Note: In case of DC24V and DC110V power supply, the symbol of the “L” and “N” of the power supply become “+” and “–”. Refer to the specific diagrams in the manual for your exact configuration (1-contact, 2-contact input, or 2-contact output).

For remote installations, dedicated or commercially available cables are used to connect the converter and detector. The cables should be no longer than 300 m (984 ft.), with the actual length depending on the fluid conductivity.

Grounding: Grounding is essential for accurate measurement. The grounding resistance must be less than 100 Ω.

Cable Diameters:

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

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

Note on Wiring: 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 equivalent or higher capacity.

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

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

• Run the cable into the terminal block through the conduit connection (G1/2, CM20, Pg13.5, or 1/2NPT). An outer diameter of φ11 (0.433 inch) is optimum (applicable range is φ10 to φ12).

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

• The maximum length of the wiring cable is 1500 m (4921 ft), but 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 (e.g., high-capacity transformers, motors). DO NOT install the cable in the same tray or duct as other power cables to avoid output errors.

• For waterproofing and damage prevention, use conduits and ducts with a waterproof cable gland.

The wiring method depends on the communication type. An external power supply is required for SFC. Change dip switch settings only after turning the power supply OFF.

The communication type (HART or SFC) must be specified when ordering. If you need to change the communication type, you must:

1. Change the dip switch position according to the communication type.

2. Change the communication type in the “COM SELECT” screen in the “Shipping Info” screen.

Note:

• Check and confirm that the wiring polarity is correct. Incorrect polarity may cause damage.

• If not using a communication function, the dip switch pins should be set as for HART communication. HART communication works with the wiring for the SFC communication.

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 to the equipment. Use an external power supply that meets the voltage and capacity specifications. Pulse may be output when the power is turned ON or OFF. The pulse output protection circuit causes a voltage drop; some counters may not pick up pulses due to this drop. In such cases, turn On the S6 switch on the main card.

Contact Input Wiring:

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

• Semi-conductive contact specifications: OFF: Withstand voltage 30V min, Leak current 0.1mA max. ON: Saturation voltage 3V max, ON current 15mA max.

• No-voltage contact specifications: OPEN: Resistance 100kΩ min, CLOSE: Resistance 400Ω max.

Contact Output Wiring:

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

Note: For both input and output, 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 can be confirmed and manipulated. The system has four modes:

• Basic setup mode: For day-to-day running.

• Engineering mode: For flowmeter configuration.

• Maintenance mode: For system maintenance.

• Advanced mode: For specific noise immunity and other advanced functions.

To set the level:

1. Remove the four screws and the display cover.

2. Locate the write protection switch on the main card.

3. Set the write protection switch positions to the required level of protection as shown in the table below.

✗ – Neither data confirmation nor manipulation are possible.

To check and set the communication switch for HART:

1. Remove the four screws and the display cover.

2. Locate the communication switch on the main card.

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

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

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

1. Remove the four screws and the display cover.

2. Locate the empty detection function switch (marked EP) on the main card.

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

To check and set the communication switch for SFC:

1. Remove the four screws and the display cover.

2. Locate the communication switch on the main card.

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

WARNING: ELECTRIC SHOCK HAZARD! DO NOT perform wiring work while the power is ON!

A commercial power supply (AC 100-120V, 200-240V, 50-60Hz) or a 24 VDC ± 10% power supply is required. The specific power supply requirement is shown on the nameplate of your converter.

The 24 VDC converter has a terminal marked “POWER DC24V” instead of “POWER”.

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

2. Confirm that the wiring between the converter and detector has been properly completed. For HART/SFC communication, verify the wiring is appropriate.

3. Begin and then stop fluid flow through the detector to ensure it is filled with fluid in a static condition.

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

5. Apply power to the converter.

6. The display will appear seven seconds after power is ON.

7. Zero the flowmeter using the procedure for “Auto zero”. The flowmeter is now on and operational.

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

Touch Sensor Key Functions

Default Settings

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.

Auto zero adjusts the flowmeter so that the measured flow rate is zero when the fluid is in a static condition inside the detector. Before operating for the first time, be sure to carry out auto zero.

CAUTION: Before performing auto zero, ensure the detector is properly grounded (<100 Ω), filled with the fluid to be measured, and the fluid is in a static condition (0.0 m/s for accurate adjustment). If these conditions cannot be guaranteed, the auto zero function should be ignored.

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.

4. Touch the UP key once to start the auto zero adjustment. The large numerical display flashes and READY changes to ON. When complete, the flashing stops and ON changes back to READY. The process takes approximately 60 to 100 seconds.

5. Touch the RIGHT SHIFT key until the cursor is back at the mode indicator. Touch the MODE key and hold for three seconds to return to MEASUREMENT MODE to save the zero setting.

This function resets the current totalized value to 000000000 and saves it to memory.

1. Enter BASIC SETUP MODE. (The first screen is always the TAG screen).

2. Use the UP or DOWN key to cycle through screens until the CNT-RESET screen appears (it will show CNT-RESET READY).

3. Touch the RIGHT SHIFT key once to move the cursor to READY.

4. Touch the UP key to select READY and reset the counter. READY changes to ON as the counter resets and then changes back to READY when done.

5. Touch the RIGHT SHIFT key until the cursor is back at the mode indicator. Touch the MODE key and hold for three seconds to return to MEASUREMENT MODE and save the change.

This function selects the constant (EX), model type (MGG, KID, etc.), and diameter (DIA) of the detector being used.

CAUTION: If the converter and detector were purchased together, the converter contains the detector data set during actual flow calibration. DO NOT change this data, or the flowmeter output will be incorrect.

1. Enter BASIC SETUP MODE.

2. Use the UP or DOWN key to cycle to the detector DATA (EX/DIA) screen.

3. Touch the RIGHT SHIFT key to move the cursor to the value you want to change (EX, detector type, or DIA).

4. Use the UP or DOWN key to change the selected value.

5. Repeat for other values as needed. When finished, touch the RIGHT SHIFT key until the cursor is back at the mode indicator.

Critical problems can disrupt flowmeter operation. When a critical error occurs, an error message appears, and the flowmeter outputs the preset fail-safe value.

Non-critical problems do not seriously disrupt operation. The flowmeter continues to output the flow rate.

The analog output can be checked by using the flowmeter as a constant-current generator. The setting range is 000.0 to 115.0%.

1. Enter MAINTENANCE MODE. Use the UP or DOWN key to cycle to the “OUTPUT CHECK” screen. Touch the RIGHT SHIFT key once to move the cursor to “OFF”. Touch the UP key to switch the OFF screen to ON.

2. The screen will show `> OUTPUT CHECK I. OUT 000.0 %`. Touch the RIGHT SHIFT key to move the cursor to the percent value to be checked.

3. Use the UP or DOWN key to set the desired output value. For example, setting it to 100.0% will output 20mA.

4. Touch the RIGHT SHIFT key to move the cursor back to the “>”.

5. Use the UP or DOWN key to move to another screen. The analog output will return to the value corresponding to the measured flow rate.

Note: If no operation is done for ten minutes, the output check mode automatically finishes and returns to the Measuring mode.

The pulse output can be checked by using the flowmeter as a pulse generator. The setting range is 000.0 to 115.0%.

1. Enter MAINTENANCE MODE. Cycle to the “OUTPUT CHECK I.OUT” screen, turn it ON, then touch the UP or DOWN key to move to the “OUTPUT P. OUT” screen.

2. The screen will show `> OUTPUT CHECK P. OUT 000.0 %`. Touch the RIGHT SHIFT key to move the cursor to the percent value.

3. Use the UP or DOWN key to set the desired value. For example, setting to 100.0% will output a pulse equivalent to the 100% flow rate.

4. Touch the RIGHT SHIFT key to move the cursor back to the “>”.

5. Use the UP or DOWN key to move to another screen. The pulse output will return to the value corresponding to the measured flow rate.
