Brand | S-iemens |
Model | 7MF4033-1BA10 |
Series | Sitrans DS III |
Type | Digital Pressure Transmitter |
Measurement | Pressure, Differential Pressure |
Sequence | Operation Steps | Description |
1 | Power-on and Initial Display | Upon powering on, the transmitter will usually display the measured value. |
2 | Access Menu | Press the [M] key to select options, use the [↑] and [↓] keys to change assignments, and press [M] again to confirm selections. |
3 | Keyboard Lock | Ensure the keyboard lock is off to perform key operations. |
4 | Display Adjustment | The display shows measurement values, engineering units, sign, operating status, and working mode. The square root symbol is used for differential pressure and flow measurements. |
5 | Communication Status | When the instrument is in communication, e.g., with a HART communicator, the communication indicator will flash. |
6 | Zero and Span Setting | Use keys [M], [↑], and [↓] to set the zero and span. Set the zero output current to 4mA and span to 20mA. Follow the instrument's prompts for specific steps. |
7 | Measurement Range | The measurement range is selectable, typically from 0-100Pa to 3MPa for differential pressure, and 0-1kPa to 40MPa for pressure. |
8 | Output Signal | The output signal is a standard analog signal of 4-20mA, used for transmitting measured values. |
9 | Communication Protocols | Supports communication protocols such as HART, PROFIBUS-PA, and FF (specific protocols depend on the selected model). |
10 | Error Handling | If a hardware or software fault occurs, an "Error" message will appear on the display. Diagnostic information can also be obtained through HART communication. |
11 | Maintenance and Inspection | Regularly check the instrument's zero point and perform internal self-tests for faults such as sensor damage or HW/FW errors. |
12 | Safety and Explosion Protection | The transmitter has intrinsic safety and explosion-proof protection levels, suitable for use in explosion-hazardous areas (Zone 0). |
13 | Installation and Wiring | The 7MF4033 pressure transmitter is a two-wire instrument. Connect the transmitter to the control room's analog input module using only two wires, which serve as both power and signal lines. |
