3. Setup jeung Instalasi
Proper installation is crucial for the safe and accurate operation of the MC701 controller. Please follow these steps carefully:
3.1 Pamasangan Panel
- Cut a rectangular opening in your control panel according to the controller's dimensions (8.0 cm x 8.0 cm).
- Insert the MC701 controller into the opening from the front.
- Secure the controller using the provided mounting bolts/clips from the rear of the panel. Ensure it is firmly seated.
3.2 Sambungan Wiring
Refer to the wiring diagram below for correct electrical connections. Incorrect wiring can damage the unit or connected equipment.
Detailed Wiring Diagram for MC701
- Catu Daya (85-265VAC): Connect your AC power source to terminals 8 and 9.
- Input sénsor:
- For Thermocouple (TC, e.g., K-type): Connect the positive (+) lead to terminal 6 and the negative (-) lead to terminal 5.
- For RTD (e.g., Pt100): Connect the 'A' lead to terminal 4 and the 'B' leads to terminals 5 and 6 (short 5 and 6 together).
- SSR Output: Connect the SSR control input to terminals 10 (+) and 11 (-).
- Kaluaran Relay: Connect the relay contacts to terminals 12 (NO - Normally Open) and 13 (NC - Normally Closed). Terminal 14 is the Common (COM).
- Alarm Output (AL1, AL2): Terminals 1, 2, 3 are for alarm outputs. Consult the full manual for specific alarm configurations.
Awas: Ensure all power is disconnected before performing any wiring. All wiring should be done by a qualified professional.
4. Parentah Operasi
The MC701 features a dual digital display (PV for Process Value, SV for Set Value) and intuitive buttons for operation.
4.1 Kadali Panel hareup
- PV Display (Upper): Némbongkeun suhu anu diukur ayeuna.
- SV Display (Lower): Shows the target temperature (set value).
- Tombol SET: Dianggo pikeun asup ka modeu setélan parameter sareng mastikeun pilihan.
- < (Shift) Button: Used to shift digits when setting values.
- V (Down) Button: Decreases the value of the selected digit.
- ^ (Up) Button: Increases the value of the selected digit.
- Indikator OUT: Nyaangan nalika kaluaran aktip.
- Indikator AT: Illuminates during auto-tuning.
- ALM1/ALM2 Indicators: Illuminate when respective alarms are active.
4.2 Setting the Target Temperature (SV)
- Dina modeu operasi normal, pencét tombol SET tombol sakali. Pintonan SV bakal mimiti kedip-kedip.
- Ngagunakeun éta <, V, jeung ^ buttons to adjust the desired target temperature.
- Pencét SET again to confirm the new value and exit the setting mode.
4.3 PID Auto-Tuning
The auto-tuning function helps the controller optimize its PID parameters for your specific heating/cooling system, ensuring stable and accurate temperature control.
- Ensure the controller is connected to your system and the process is stable.
- Pencét jeung tahan tombol SET button for approximately 3-5 seconds until the parameter menu appears.
- Navigate through the parameters (using SET to cycle) until you find the auto-tuning parameter (often labeled 'AT' or similar).
- Set the auto-tuning parameter to 'ON' or initiate the auto-tuning process (refer to the full manual for exact parameter names and values). The AT indikator bakal caang.
- The controller will cycle the output to learn the system's characteristics. This process may take some time (e.g., 2-3 heating/cooling cycles).
- Once auto-tuning is complete, the AT indicator will turn off, and the optimized PID parameters will be saved automatically.
4.4 Changing Temperature Unit (Celsius/Fahrenheit)
The MC701 allows you to switch between Celsius and Fahrenheit display units. This setting is typically found within the advanced parameter menu.
- Pencét jeung tahan tombol SET button for approximately 3-5 seconds to enter the parameter menu.
- Cycle through the parameters using the SET button until you find the temperature unit setting (e.g., 'C/F' or 'UNIT').
- Ngagunakeun éta V or ^ buttons to select 'C' for Celsius or 'F' for Fahrenheit.
- Pencét SET to confirm and exit the parameter menu.
5. Pangropéa
The SINOTIMER MC701 is designed for reliable operation with minimal maintenance. However, regular checks can help ensure its longevity and accuracy.
- beberesih: Periodically wipe the front panel with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Sambungan: Annually inspect all wiring connections to ensure they are secure and free from corrosion. Loose connections can lead to inaccurate readings or intermittent operation.
- Lingkungan: Ensure the operating environment remains within the specified temperature and humidity ranges to prevent damage to internal components.
Awas: Always disconnect power to the controller before performing any maintenance or cleaning.
6. Cara ngungkulan
This section provides solutions to common issues you might encounter with your MC701 controller.
| Masalah | Mungkin Cukang lantaranana | Solusi |
|---|---|---|
| Teu aya tampilan/Pareuman | No power supply; Incorrect wiring; Blown fuse (internal) | Check power connections (terminals 8 & 9). Verify voltage. Consult a technician for internal fuse check. |
| Layar PV némbongkeun 'HHHH' atawa 'LLLL' | Sensor open circuit (HHHH); Sensor short circuit (LLLL); Sensor type mismatch; Sensor out of range | Check sensor wiring and connections. Verify sensor type matches controller setting. Ensure sensor is within its operating range. Replace faulty sensor. |
| Maca suhu teu akurat | Sensor calibration error; Sensor faulty; Electrical interference | Perform sensor calibration if available. Replace sensor. Ensure proper grounding and shielding of sensor wires. |
| Output (Relay/SSR) not activating | SV not reached; Output wiring incorrect; PID parameters not tuned; Output component faulty | Check SV and PV values. Verify output wiring (terminals 10-11 for SSR, 12-14 for Relay). Perform auto-tuning. Test output component. |
| Temperature overshoots/undershoots | PID parameters not optimized | Perform PID auto-tuning. Adjust PID parameters manually if necessary (refer to advanced settings in full manual). |
6.1 Tips pamaké
- For best performance, always perform PID auto-tuning after initial setup or if the heating/cooling load changes significantly.
- When using a K-type thermocouple, ensure the correct polarity is observed during wiring to avoid incorrect readings.
- Consider using shielded cables for sensor connections in noisy electrical environments to minimize interference.
