Connect the positive (+) input of your Solid State Relay to Terminal 6 and negative (-) to Terminal 7. 3. Panel Description
If you are running a compressor, refrigeration unit, or mechanical relay that cannot handle rapid pulsing, use ON/OFF control:
Press the key again to move to the tens, hundreds, or thousands digit.

| Problem | Possible Cause | Solution | | :--- | :--- | :--- | | | No power, incorrect power supply wiring, or a faulty power source. | Check power supply. Verify terminals 1 & 2 are correctly wired to 85-265V AC.| | Display shows "S.err", "orA" or similar error code | Sensor is not connected, is disconnected, or is faulty. The input signal is outside the measurable range. | Check your sensor wiring to terminals 8-10. Ensure the correct sensor type is selected in the In parameter. Test the sensor for continuity.| | Temperature is very inaccurate | Wrong sensor type selected in settings ( In parameter), sensor not properly positioned, or a faulty sensor. | Verify the In parameter matches your sensor (e.g., K for K-type thermocouple). Reposition sensor for better contact or replace it.| | Temperature oscillates or overshoots constantly | PID parameters are not tuned for your system. | Run the Auto-Tune (AT) function to optimize the PID values.| | Controller is not switching the output | Incorrect output wiring, faulty relay/SSR, or the output is being prevented by an alarm. | Check wiring to terminals 3-5 (Relay) or 11-12 (SSR). Check the alarm settings ( AL1 ).| | The alarm is always on or never activates | Alarm setpoint ( AL1 ) is incorrectly configured, or the alarm mode is wrong. | Review the AL1 parameter value and ensure it's set appropriately for your process. Check the alarm mode settings (upper-limit, lower-limit, etc.) in the advanced parameters.|

Connect your 85–265V AC main power lines here. Control Output (Terminals 3, 4 & 5):
The MC101 is part of the MC series (48mm x 48mm size) known for accurate temperature measurement and control. MC101 (48x48mm Panel Size) Measurement Accuracy: Full Scale Resolution: 14-bit Sampling Cycle: 0.5s Input Types: Thermocouple: K, J, R, S, B, E, N, T Thermal Resistance: Pt100, Cu50
Always disconnect the power supply before wiring the instrument. Check the label on the side of your specific unit, as terminal layouts can vary slightly by sub-model. Standard Terminal Layout Reference
The Sinotimer MC101 allows for (Programs 1 through 16). Each program consists of an "ON" time and an "OFF" time. For example, Program 1: ON at 06:00; OFF at 09:00. This article serves as the definitive online manual
