Code :

Code: 541-02
Description: Thermistor (center) disconnection: Low voltage An error is detected only when the input voltage at power-on is low. • Temperature of 0°C or lower is detected for 20 seconds continuously.
Causes: • Thermistor (center) disconnection • Thermistor (center) not connected correctly
Remedy: • Reconnect the thermistor (center). • Replace the thermistor (center). • Clear this SC by executing SP5-810-001.

Code: 542-01
Description: Reload failure: Thermistor deformation The temperature of 9°C or lower is detected five times consecutively for three seconds. • Measurement begins 15 seconds after the heater is turned on. • Measurement interval: 0.1 sec. • If the reload temperature is reached during measuring, the measurement is cancelled.
Causes: • Thermistor deformed • Thermistor out of position • Out of guaranteed input voltage
Remedy: • Replace the thermistor (center). • Clear this SC by executing SP5-810-001.

Code: 542-03
Description: Reload failure: Heater damage Normal (no pre-rotation): • The reload temperature is not reached for 35 seconds after heater control starts. Pre-rotation: • The reload temperature is not reached for 90 seconds after heater control starts.
Causes: • Heater damaged • After over-heat prevention
Remedy: • Replace the heater. • Clear this SC by executing SP5-810-001.

Code: 542-04
Description: Reload failure: Low voltage and thermistor deformation An error is detected only when the input voltage at power-on is low. The temperature of 7°C or lower is detected five times consecutively for 3 seconds. • Measurement begins 15 seconds after the heater is turned on. • Measurement interval: 0.1 sec. • If the reload temperature is reached during measuring, the measurement is cancelled.
Causes: • Thermistor deformed • Thermistor out of position • Out of guaranteed input voltage • After over-heat prevention
Remedy: • Replace the thermistor (center).

Code: 542-06
Description: Reload failure: Low voltage and heater deformation An error is detected only when the input voltage at power-on is low. • Normal (no pre-rotation): The reload temperature is not reached for 90 seconds after heater control starts. • Pre-rotation: The reload temperature is not reached for 285 seconds after heater control starts.
Causes: • Heater damaged • After over-heat prevention
Remedy: • Replace the heater.

Code: 543-00
Description: Thermistor (center) high temperature detection: Software An error is detected when the temperature of 230°C or higher is detected for 1 seconds continuously. • Detection with the thermistor (center) • Detection time: 10 or more • Measurement interval: 0.1 sec
Causes: • Triac short-circuit • MPU defective
Remedy: • Replace the MPU. • Clear this SC by executing SP5-810-001.

Code: 544-00
Description: Thermistor (center) high temperature detection: Hardware An error is detected when the temperature of 250°C or higher is detected • Detection with the thermistor (center)
Causes: • Triac short-circuit • MPU control board defective • Fusing control error
Remedy: • Replace the MPU. • Clear this SC by executing SP5-810-001.

Code: 545-01
Description: Heater continuously heat An error is detected when the target temperature cannot be reached for 10 seconds or more after reloading.
Causes: • Thermistor detection error • Heater damaged • After over-heat prevention
Remedy: • Replace the thermistor (center). • Replace the heater. • Clear this SC by executing SP5-810-001.
