alarm

Alarm Description:
Laser low temperature/high temperature alarm, which occurs when the sensor
inside detects an abnormal temperature inside the laser. A high temperature
alarm is generated when the temperature of the monitoring point exceeds the set
upper limit, and a low temperature alarm is generated when the set lower limit
is exceeded.
Possible solutions:
In the event of a high temperature alarm, please check whether the water
cooling system is turned on normally, whether the water temperature setting is
correct, whether the chiller is working normally, whether the water connection
is abnormal, etc. When the water cooling system is working normally and the
water temperature drops below 30°C, please restart the laser to try.
In the case of low temperature alarm, please check whether the actual water
temperature of the chiller is too low. In addition, too low ambient temperature
may also cause a low temperature alarm when the laser start at a cold machine
state. If the above situation occurs, you need to wait until the chiller water
temperature rises above 10 °C, and then restart the laser to try.
Hum Alarm
（
Condensation
alarm
）
Alarm Description:
Laser internal condensation alarm means the laser detected the current laser
internal dew point temperature < 22 °C, there is a risk of condensation.
Possible solutions:
Stop using the laser immediately. Please follow the operation requirements to
induct cold and dry air from the CDA interface, drain moist air from the
cabinet, or improve the working environment of the laser so that the ambient
temperature is lower than the internal temperature of the laser, it is
recommended to build a separate air-conditioned room for the laser.
