Temperature/Humidity Sensor Error (Main)
One of the following occurred.
• The temperature sensor output was less than 0.5V or more than
2.8V for three seconds (one second x 3), indicating a problem with
the temperature sensor.
• The humidity sensor output was more than 2.4V for three seconds
(one second x 3), indicating a problem with the humidity sensor.
Details:
Detection is repeated after power off/on.
If either of temperature/humidity sensors works correctly, the working
C
sensor will be used even after the SC is issued.
The machine continues working with the assumption that the temperature
is 23 degrees centigrade (if there is a problem with the temperature
sensor) and/or the humidity is 50% (if there is a problem with the
humidity sensor)
