3.1 Fungsi Panel

The front panel of the MT-S controller features a clear display and intuitive buttons for operation:

• PV (Nilai Proses): Displays the measured temperature or various parameter symbols.
• SV (Nilai Tetap): Displays the desired set temperature or various parameter set values.
• Penunjuk KELUAR: Menyala apabila output kawalan aktif.
• Penunjuk AT: Menyala apabila penalaan automatik PID aktif.
• Petunjuk AL1: Illuminates when Alarm 1 is triggered.
• ▲ (Anak Panah Atas): Meningkatkan nilai berangka semasa penetapan.
• ▼ (Anak Panah Bawah): Mengurangkan nilai berangka semasa penetapan.
• ◀ (Kekunci Shift): Moves the cursor or shifts digits during setting.
• Butang MOD: Digunakan untuk memanggil parameter dan mendaftarkan nilai yang ditetapkan.

4.2 Sambungan Pendawaian

Proper wiring is crucial for the safe and correct operation of the temperature controller. Refer to the wiring diagram on the back of the unit and the detailed output/input method diagram below.

Rajah 4: Belakang view with wiring terminals.

Kaedah Output:

• Output geganti: Directly connected to the heat pipe or an AC contactor. The relay contacts are rated at 3A / 250VAC.
• Output Keadaan Pepejal (SSR): Connected to a Solid State Relay. The voltage impulse output is 12VDC, designed to control an external AC solid state relay.

Kaedah Input:

The controller accepts thermocouple inputs with index numbers K, J, E, or N. Ensure the correct thermocouple type is selected on the panel to match your sensor.

WARNING: All wiring should be performed by a qualified electrician. Ensure power is disconnected before making any connections to prevent electric shock or damage to the unit.

5. Operasi

5.1 Tetapan Suhu Asas

1. Power on the device. The PV display will show the current measured temperature, and the SV display will show the set temperature.
2. Tekan ke MODE butang sebentar untuk memasuki mod pelarasan nilai yang ditetapkan. Paparan SV akan berkelip.
3. Gunakan ▲ dan ▼ buttons to adjust the desired temperature. Use the ◀ (Shift) key to move between digits for faster adjustment.
4. Tekan ke MODE button again to confirm the new set value and exit the adjustment mode.

5.2 Control Mode Selection (PID / ON/OFF)

The controller supports both PID and ON/OFF control modes. ON/OFF control is activated when the 'P' parameter (proportional band) is set to 0. For more advanced control and stability, use PID mode.

Refer to the full English manual (included in the package) for detailed instructions on accessing and adjusting advanced parameters, including PID settings and thermocouple type selection.

5.3 Tetapan Penggera

The controller features one alarm with six different modes: high deviation, low deviation, and process value alarm. These can be configured through the parameter settings. Consult the detailed manual for specific alarm parameter adjustments.

6. Penyelenggaraan

• Pembersihan: Lap unit dengan kain lembut dan kering. Jangan gunakan pembersih atau pelarut yang melelas.
• Keadaan Persekitaran: Ensure the controller operates within the specified ambient temperature (0-50°C) and humidity (30-85%RH) range. Avoid environments with corrosive gases.
• Pemeriksaan: Periksa sambungan pendawaian secara berkala untuk kesesakan dan tanda-tanda haus atau kerosakan.

7. Penyelesaian masalah

If you encounter issues with your SINOTIMER MT-S controller, consider the following basic troubleshooting steps:

• Tiada Kuasa: Check the power supply connections and ensure the voltage is within the AC100-240V range.
• Bacaan Suhu yang salah: Verify that the correct thermocouple type is selected in the controller's settings and that the thermocouple is properly connected and not damaged.
• Output Tidak Diaktifkan: Check the OUT indicator. Ensure the set temperature (SV) is appropriately configured relative to the process value (PV) for heating or cooling. Verify output wiring.
• Unstable Temperature Control: If using PID mode, consider performing an auto-tune cycle. If using ON/OFF mode, ensure the hysteresis (deadband) is set appropriately.
• Penggera Tidak Berfungsi: Check alarm settings and ensure the alarm mode and set points are correctly configured.

For more complex issues, refer to the comprehensive English manual provided with your product or contact customer support.
