6. Installation and Wiring
Before installation, ensure the power supply is disconnected. The MC101 controller is designed for panel mounting. Refer to the wiring diagram below for proper electrical connections.
Text Description of Wiring Diagram: The diagram illustrates the terminal connections on the side of the MC101 controller. Terminals 1 and 2 are for the 100-240VAC power supply. Terminals 3, 4, and 5 are for the Relay Output (3: Normally Open, 4: Common, 5: Normally Closed). Terminals 6 (+) and 12 (-) are for the Solid State Relay (SSR) Output. Terminals 7 (A) and 8 (B) are for the Alarm Output. For RTD (Resistance Temperature Detector) input, connect to terminals 8 (A), 9 (B), and 10 (B). For Thermocouple (TC) input, connect to terminals 9 (-) and 10 (+).
Wiring Steps:
- Power Supply: Connect your 100-240VAC power source to terminals 1 and 2.
- Output Wiring:
- For Relay Output: Connect your controlled device to terminals 3 (NO) or 5 (NC) and 4 (Common) as required by your application.
- For SSR Output: Connect the SSR input to terminals 6 (+) and 12 (-).
- Sensor Input:
- For RTD Sensor: Connect the RTD sensor to terminals 8 (A), 9 (B), and 10 (B).
- For Thermocouple Sensor: Connect the thermocouple sensor to terminals 9 (-) and 10 (+).
- Alarm Output (Optional): If using an alarm, connect it to terminals 7 (A) and 8 (B).
- Double-check all connections for correctness and security before applying power.
7. Operation
7.1 Initial Power-Up
Once wired correctly, apply power to the controller. The LED display will light up, showing the Process Value (PV) and Set Value (SV).
7.2 Setting Parameters
The MC101 features a user-friendly interface with buttons for setting parameters:
- SET button: Used to enter parameter setting mode and confirm selections.
- < / R/S button: Used to shift digits during value adjustment or to reset/run.
- V (Down) button: Decreases the value of the selected digit.
- ^ (Up) button: Increases the value of the selected digit.
Detailed parameter settings, including input type selection (thermocouple/RTD), temperature unit (°C/°F), and PID parameters, are typically accessed by pressing and holding the SET button for a few seconds to enter the configuration menu. Refer to the on-screen prompts and the full English User Manual (if provided separately) for specific menu navigation and parameter definitions.
7.3 Auto-Tune Function
The auto-tune function automatically calculates optimal PID parameters for your specific heating/cooling system. To activate auto-tune, typically you would enter the parameter setting mode and select the auto-tune option. The controller will then cycle the output to analyze the system response and determine the best PID values. This process may take some time, during which the system temperature will fluctuate.
7.4 Heating and Cooling Control
The MC101 can be configured for either heating or cooling control. This setting determines whether the output activates when the temperature is below or above the setpoint, respectively. Ensure this parameter is correctly set for your application.
8. Maintenance
- Cleaning: Clean the controller's display and casing with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Inspection: Periodically inspect wiring connections for looseness or signs of damage.
- Environment: Ensure the operating environment remains within the specified temperature and humidity ranges to prolong the life of the device.
9. Troubleshooting
If you encounter issues with your MC101 controller, consider the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No display/Power off | No power supply; incorrect wiring; blown fuse. | Check power connections (Terminals 1 & 2). Verify power source. Inspect internal fuse if accessible (refer to service manual). |
| Incorrect temperature reading | Wrong sensor type selected; sensor wiring error; faulty sensor. | Verify sensor type setting in parameters. Check sensor wiring (RTD: 8,9,10; TC: 9,10). Test sensor functionality. |
| Output not activating | Incorrect output wiring; setpoint not reached; PID parameters need tuning; faulty output relay/SSR. | Check output wiring (Relay: 3,4,5; SSR: 6,12). Adjust setpoint. Run auto-tune. Test output with a multimeter (power off). |
| Temperature oscillates widely | PID parameters are not optimized. | Run the auto-tune function to optimize PID parameters for your system. |
For persistent issues, please contact customer support.
10. User Tips
- Always perform an auto-tune after initial setup or if you change your heating/cooling element or sensor, to ensure optimal performance.
- Keep the controller away from strong electromagnetic interference to prevent inaccurate readings.
- Familiarize yourself with the parameter menu structure to quickly adjust settings as needed.
