Correct wiring is critical for safe operation. Always disconnect power before making connections. Refer to the specific diagram on your unit's label for the most accurate pinouts.
Power Input: Connect the AC power supply to Terminals 1 and 2 (typically 120V/240V L and N). Sensor Connection:
Thermocouples: Connect the positive and negative leads to the designated input terminals (check label for polarity).
RTD (3-wire): Connect the resistor element between Terminals 8 and 9, with the third "extra" wire going to Terminal 10. Control Output:
For Relay Output models, use the internal relay contacts to switch your load.
For SSR Output models, connect Terminal 5 (positive) and Terminal 4 (negative) to the control input of your Solid State Relay. Configuration and Setup
To customize the controller for your specific application, use the panel keys (SET, <, ∨, ∧). Setting the Temperature (SV): Press the SET key briefly. Use the < key to select the digit you want to change. Use the ∨ and ∧ keys to adjust the value. Press SET again to save the new target temperature. Switching Units (°C to °F):
Hold the MODE (or SET + <) keys for 3 seconds to enter the menu. Use the arrows to find the "Unit" parameter. Change the value from 000 (Celsius) to 001 (Fahrenheit). Hold the MODE key for 3 seconds to exit and save. Entering PID Auto-Tuning:
For optimal control, you can trigger the Auto-Tuning (AT) function. Access the internal menu and locate the "AT" parameter.
Set "AT" to 1. The AT light on the panel will blink until the cycle is complete and the controller has calculated its PID constants. Safety and Maintenance
Heat Dissipation: If using an SSR to control a high-current load, always attach a heat sink to prevent the relay from overheating.
Input Matching: Ensure the thermocouple type set in the software matches the physical sensor connected to avoid incorrect readings.
Environmental Protection: Sinotimer devices are built to resist dust and moisture, but they should still be housed in a proper enclosure for longevity in harsh environments. Temperature Controller - Sinotimer
