SC No. Level Error Name/Error Condition/Major Cause/Solution
542-04 B 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.
• Thermistor deformed
• Thermistor out of position
• Out of guaranteed input voltage
• After over-heat prevention
• Replace the thermistor (center).

• 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
