Warning E09: the temperature of laser bar exceeds the upper limit

Warning E09: the temperature of laser bar exceeds the upper limit

a) This failure means that “semiconductor laser temperature exceeds the upper limit”. At this time, check whether the semiconductor laser is damaged in time.

b) Once an alarm occurs, enter the background to view the temperature. If it is above 60℃ but the actual temperature does not reach this value, judge it is the caused by the abnormality of handpiece temperature sensor. At this time, check whether the sensor has virtual connection; if no problem is discovered, replace handpiece control board.
