This manual provides essential information for the safe and effective installation, operation, and maintenance of your temperature controller.
2. Setélan
2.1 Instalasi fisik
The MT-M model has a panel size of 72 x 72mm and requires an installation hole size of 68 x 68mm. Ensure the mounting location is free from excessive vibration, moisture, and corrosive gases. The controller is made of plastic.
2.2 Wiring jeung sambungan
Proper wiring is crucial for the safe and correct operation of the temperature controller. Refer to the diagram below for output and input connections. Always ensure power is disconnected before performing any wiring.
Métode kaluaran:
- Relay Output (RELAY): Can be directly connected to a heat pipe or to an AC contactor. The contact capacity is 3A at 250VAC (resistive load).
- Solid State Output (SSR): Connects to an external Solid State Relay. This provides a 12VDC voltage impulse output to control a DC-controlled AC solid state relay.
Métode Input:
- The controller accepts thermocouple inputs with index numbers K, E, J, or N. Ensure the correct thermocouple type is selected in the controller's settings to match your sensor.

3.2 Operasi Dasar
- Daya Hurung: Connect the controller to an AC100-240V 50/60HZ power supply. The display will light up, showing the current measured temperature (PV) and the set temperature (SV).
- Setting Temperature (SV): Ngagunakeun éta ▲ jeung ▼ buttons to adjust the Set Value (SV). Use the ◀ key to shift between digits for faster adjustment. Press MODÉ to confirm the new SV.
- Modeu kontrol: The controller supports PID and ON/OFF control. ON/OFF control is active when the P (proportional band) parameter is set to 0. Refer to the full manual for advanced PID tuning parameters.
- Fungsi Alarm: The controller has one alarm with 6 modes: high deviation, low deviation, and process value alarm. Configure alarm parameters as needed for your application.
- Unit Suhu: The display can show temperature in Celsius (℃) or Fahrenheit (°F). This setting can be changed by the user.
4. Pangropéa
To ensure the longevity and accurate performance of your SINOTIMER MT-M controller, follow these maintenance guidelines:
- beberesih: Keep the controller's display and buttons clean. Use a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Kaayaan Lingkungan: Operate the controller within the specified ambient temperature range of 0-50°C and humidity of 30-85% RH (non-condensing). Avoid exposure to corrosive gases, excessive dust, or direct sunlight.
- Sambungan: Périodik pariksa sagala sambungan wiring pikeun mastikeun aranjeunna aman tur bebas tina korosi.
5. Cara ngungkulan
If you encounter issues with your temperature controller, consider the following general troubleshooting steps:
- Henteu aya kakuatan: Pariksa sambungan catu daya sareng pastikeun voltasenatage is within the AC100-240V range.
- Bacaan Suhu Lepat: Verify that the thermocouple is correctly connected and that the input type selected in the controller matches your thermocouple (K, E, J, or N). Ensure the thermocouple is properly inserted into the process.
- Kaluaran Teu Aktipkeun: Check the set temperature (SV) against the measured temperature (PV). Ensure the control mode (PID/ON-OFF) and associated parameters are correctly configured. Verify external relay or SSR connections.
- Alarm Issues: Review the alarm settings and ensure they are configured as desired. Check if the alarm condition is met.
For more complex issues, consult the full product manual or contact customer support.

7. Tips pamaké
- Panempatan sénsor: For accurate temperature control, ensure your thermocouple is placed in a location that accurately represents the temperature of the process you are controlling, away from direct drafts or heat sources that are not part of the process.
- Pangaturan PID: While the controller offers PID auto-tuning, manual fine-tuning may be necessary for optimal performance in specific applications. Experiment with P, I, and D parameters to achieve stable and precise control without overshoot or oscillation.
- Output Type Selection: Carefully choose between Relay and SSR output based on your application's power requirements and switching frequency. SSRs are generally preferred for faster switching and longer lifespan in high-frequency applications.
