To set up the VC-4PT Resistive Temperature Input Module for temperature measurement using different types of RTD sensors, follow these steps based on the user manual:
1. **Wiring Instructions:**
- Connect the RTD sensors (Pt100, Cu100, Cu50) using shielded cables.
- Route the cables away from power cables or other wires that may cause electrical interference.
- Use a 4-wire system for connections longer than 10m for accurate measurements.
- Keep the connection cable length under 100m to reduce measurement errors.
- Connect the shield ground terminal in case of excessive electrical interference.
- Connect the external power supply PE to a good earth.
2. **Channel Configuration:**
- The VC-4PT has 4 channels for RTD sensors.
- Each channel can be configured for a specific RTD type (Pt100, Cu100, Cu50).
- Set the channel characteristics by determining two points (A0, D0) and (A1, D1) for linear relationship calibration.
- Adjust the channel characteristics to match the actual temperature readings for accurate measurements.
3. **Programming Example:**
- Configure the hardware settings for the VC-4PT module in your project.
- Set up each channel to connect to a specific RTD sensor type and output temperature values in Celsius or Fahrenheit.
- Adjust the settings for each channel based on the actual measured temperatures to eliminate errors.
4. **Installation and Operational Check:**
- Mount the VC-4PT module as per the installation size and method described in the manual.
- Perform routine checks to ensure correct wiring, module connection, and power supply.
- Check for any faults by verifying the status indicators and analog wiring.
5. **User Warranty Information:**
- The warranty period for the VC-4PT module is eighteen months from the date of manufacture.
- Keep the warranty card and contact the customer service center for any issues or repairs during the warranty period.
By following these steps and guidelines provided in the user manual, you can effectively set up and use the VEICHI VC-4PT Resistive Temperature Input Module for accurate temperature measurements using different types of RTD sensors.
