Y Development Temperature Detection Error
Temperature Sensor Output Error: 0.35V or lower (100 degrees
centigrade or higher) or 3.07V or higher (-30 degrees centigrade or
lower).
Details:
In case of a Temperature Sensor Output Error: 0.35V or lower (100
degrees centigrade or higher) or 3.07V or higher (-30 degrees
centigrade or lower), the machine determines the sensor is malfunctioning
and assumes that the temperature is 100 degrees centigrade.
If the sensor is determined as malfunctioning 3 times consecutively (3
outputs, each of which is an average of 6 readings), the machine issues
the SC and no longer use the sensor, using the assumed temperature
"100 degrees centigrade" instead.
However, the sensor is used again after power off/on.
• Connecter disconnected or harness broken
• Sensor defective
• Connecter disconnected or harness broken: Revert connection.
• Sensor defective: Replace the sensor.
