Alarm instructions and solutions
Instruction:
Low temperature/high temperature alarm of the laser. The sensor in the laser
detects an abnormal temperature inside the laser. A high-temperature / low-
temperature error occurs when the temperature at the monitoring point exceeds
the set upper / lower limit.
Solution:
High temperature alarm,please check if the water-cooling system is normally
working, the water temperature is set correctly, and the water connection is
correct. When the water cooling system works normally and the water
temperature drops below 30°C, restart the laser.
Low temperature alarm, please check if the actual water temperature of the
water is too low. In addition, a low ambient temperature may also cause a low
temperature alarm when the laser is cold. Please wait until the water temperature
of the water rises above 10°C.
Instruction:
There is a condensation alarm inside the laser. The dew point temperature inside
the laser is less than 22℃, and there is a condensation risk.
Solution:
Immediately stop using the laser.
Measure 1: Refering to the section 4.2, connect clean and dry air from CDA
port to reduce relative humidity.
Measure 2: Installing cabinet air conditioner to reduce ambient temperature.
Instruction:
The water flow rate of the laser alarms. The current water flow rate detected
inside the laser is lower than the required value, and there is a safety risk.
Solution:
Stop using the laser immediately.Please check the output model and working
status of the laser water cooler and clean the laser water filter module according
to the laser operation requirements in the section 3.3 cooling System
Installation and Requirements.It is recommended to clean the water cooler
and the water inlet filter assembly regularly, and replace the cooling water.
Instruction:
Scattering light alarm, when the intensity of ambient light inside the laser
exceeds the set value, the scattering light alarm will be generated, and the laser
emission function will be locked (cannot be unlocked). The scattered light alarm
only occurs when the laser emission.
