3. Enstalasyon ak Enstalasyon
3.1 Debalaj ak enspeksyon
Upon receiving the M-3802 module, carefully unpack it and inspect for any signs of damage during transit. Verify that all components listed in the packing slip are present. If any damage or missing items are found, contact your supplier immediately.
3.2 Montaj
The M-3802 module is designed for DIN-rail mounting. Ensure the mounting surface is stable and provides adequate ventilation. Follow these steps:
- Attach the module to a standard 35mm DIN-rail by hooking the top edge of the module onto the rail.
- Push the bottom of the module firmly until it clicks into place.
- Ensure the module is securely fastened and does not wobble.
3.3 Koneksyon fil elektrik
The M-3802 utilizes a Removable Terminal Block (RTB) for all power and signal connections. This allows for pre-wiring and easy module replacement without re-wiring. Ensure all power is disconnected before making any connections.
- Antre pouvwa: Connect the module to a stable 24 VDC power supply. Observe polarity.
- Entran analog: Connect your 4-20mA current loop sensors to the designated analog input terminals. The M-3802 supports 8 single-ended analog input channels. Refer to the ioLogik system documentation for specific pin assignments and wiring diagrams.
- Atè: Proper grounding is crucial for stable operation and noise reduction. Connect the module's ground terminal to a reliable earth ground.
Note: For detailed wiring diagrams and best practices for 4-20mA current loop connections, consult the comprehensive ioLogik system manual. A typical wiring diagram for an 8-channel analog input module involves connecting each sensor's positive output to an input channel and the negative output to a common ground or return path, with power supplied to the module itself.
4. Operasyon Enstriksyon
4.1 Limen
After all wiring connections are secure and inspected, apply power to the M-3802 module. Observe the LED indicators on the module; typically, a power LED should illuminate, indicating successful power-up.
4.2 Konfigirasyon
The M-3802 module is part of the Moxa ioLogik system and is configured through the ioLogik software utility or web interface. This software allows you to:
- Define input ranges and scaling for each 4-20mA channel.
- Set alarm thresholds for analog values.
- Configure data logging and communication parameters.
- Monitor real-time analog input values.
Refer to the ioLogik software manual for detailed instructions on configuring the M-3802 module and integrating it into your control system.
4.3 Akizisyon Done
Once configured, the M-3802 will begin acquiring data from the connected 4-20mA sensors. The 12-bit resolution ensures accurate conversion of the analog current signals into digital values, which can then be accessed by your control system (e.g., PLC, SCADA) via the ioLogik controller.
