This indicates an input error. Check that your thermocouple is connected correctly and securely to terminals 9 and 10. If using a Pt100, ensure all three wires are connected correctly. How do I switch from Celsius to Fahrenheit? Enter the Parameter Menu, find the setting for or unit selection, and switch it from Why is my temperature exceeding the set point (overshoot)?
Fix: Turn off the power completely, wait 10 seconds, and turn it back on. If the error persists, the unit requires a factory reset or replacement. sinotimer mc101 manual
If you require the temperature to stay exactly at the target, you must use PID. Enter parameters and set rE to P . Run the system and allow it to reach the target. This indicates an input error
• Turn off the heating system immediately.• Check for a runaway heating element or a faulty sensor short-circuit. Target temperature overshoots significantly Poorly tuned PID parameters. How do I switch from Celsius to Fahrenheit
are you using (K-type thermocouple or PT100)? What application is this for (kiln, heater, etc.)? Are you using the relay output or SSR output ?
Controls how aggressively the system approaches the target temperature. I (Integral Time): Eliminates steady-state errors. d (Derivative Time): Prevents overshooting.
