Display Criteria
The sensor housing separating,
incomplete contact, open-circuited wire,
short-circuit and abnormal temperature
errors are displayed when the
temperature measured by the sensor is
+50 ℃ or higher or -50 ℃ or lower.
This error is displayed while the
corresponding fan motor is operating
and a feedback signal line contact error,
motor wire separation or motor error
occurs.
Connector Slipped-Out or Open-
Contact, Wire Cut or Short-Circuited,
Abnormal Sensing Temp : higher than
149℉(+65℃) or lower than -58℉(-50℃)
This error is displayed while the
corresponding fan motor is operating
and a feedback signal line contact error,
motor wire separation or motor error
occurs.
The error is displayed while the
corresponding fan motor is operating
and a feedback signal line contact
error, motor wire separation or motor
error occurs.
