YOKOGAWA ADMAG TI Series AXW Electromagnetic Flow Meter (25-450mm) Installation and Operation

(2) Example of Parameter Setting

Flow unit setting (optional parameter): Path "Device setup ► Detailed setup ► Pro var ► Volume ► Unit/Time Unit". If setting "l/min", select "l (lite)" (physical unit) and "/min" (time unit) respectively.

Flow range setting (numerical parameter): Path "Device setup ► Detailed setup ► Pro var ► Volume ► Span", the unit needs to be set first, and the range value will be automatically converted with the unit.

Tag number setting (alphanumeric parameter): Path "Device setup ► Detailed setup ► Device info ► Order info ► Tag No.", maximum input of 8 ASCII characters.

(3) Pre operation Zero Adjustment

Prerequisite: The sensor is filled with fluid and the flow rate is 0 (with the valve closed). For the FILDVUE/PROFIBUS PA type, all sensor blocks must first be set to "O/S" mode.

Operation path: "Device setup ► Diag/Service ► Autozero ► Execute". Double click [SET] to start, taking about 30 seconds. After completion, check the "Result ► Zero value" to confirm the result (exceeding 10cm/s will trigger a warning "092: AZ warning").

3. Use of configuration tools

BRAN/HART: Connected through BT200 or FieldMate, it needs to be parallel in a 4-20mA circuit, with load resistance ≥ 250 Ω/230 Ω respectively.

Modbus/FOUNDATION Fieldbus/PROFIBUS PA: Corresponding DTM (such as AXW4A Modbus DTM 1.1.4.0 or above) is required, and FieldMate needs to be upgraded to the corresponding version.

EtherNet/IP: Supports web configuration (requires IE8+/Chrome/Edge browser), requires installation of corresponding EDS file (supplier ID 250, product code 206).

Operation and maintenance

1. Hardware switch settings

Burnout switch: When the CPU fails, the current output direction defaults to a high value (>21.6mA), and when C1/C2 is installed, a low value (<2.4mA) is set.

Write Protect: To prevent parameter tampering, rewriting is prohibited when the hardware switch is set to "ON" (in conjunction with software write protection).

Address switch: Modbus (1-127), PROFIBUS PA (0-126), EtherNet/IP (set IP segment 4) need to be set through 8-bit dialing, and priority is controlled by the SW3-1 switch.

Terminal resistor switch (SW2): A 150 Ω terminal resistor (SW2-1/SW2-2 both "ON") is required at both ends of the Modbus bus.

2. Correction factor setting (for specific flanges)

Applicable scenarios: When using 40-125mm wafer type and specific linings (such as polyurethane rubber U, natural hard rubber H) with carbon steel flanges, a correction factor (CFL/CFH: double-sided carbon steel) needs to be set; CF1L/CF1H: single-sided carbon steel), the coefficient is marked on the nameplate or on the Yokogawa official website for reference.

Set path: such as the display screen "Device setup ► Detailed setup ► Sensors ► Low MF/High MF", Modbus address 40321 (Low MF)/40323 (High MF).

3. Fault handling

Chapter 7 of the document provides a detailed list of four types of faults: system alarms (equipment failures, such as "010: Main CPU FAIL" requiring contact with the service center), process alarms (process issues, such as "051: Empty detect" requiring fluid filling), set alarms (parameter errors, such as "060: Span cfg ERR" requiring range adjustment), and warnings (such as "087: Adhesion lv 3" requiring electrode cleaning). Each fault includes NE107 status (F/C/S/M/N), description, and countermeasures. Examples are as follows:

NE107 status error code/information reason countermeasures

F 010: Main CPU FAIL Mainboard CPU failure Contact Yokogawa Service Center

S 051: Empty detect sensor fills the pipeline with liquid through the empty tube

C 060: Span cfg ERR flow range setting error (requires 0.05<Span<16m/s) Check and correct range parameters

M 087: Adhesion lv 3 electrode adhesion insulation (resistance exceeding level 3). It is recommended to clean the electrode
