5.2 Dealing with Errors
The descriptions on different errors are listed in the following table, as well as the possible
solutions.
Error Code
Description：
Temperature error, it occurs when a temperature exceeds the setting
range is sensed, and the laser will be stopped and locked. There are four
sensors monitoring the temperature on different parts of the laser, which
we defined as T1~T4. The temperature exceeds the upper limit will
trigger 'High temperature error'. On the contrary, the temperature
exceeds the lower limit will trigger 'Low temperature error'.
Possible Solution：
High Temperature Error: Please check if the cooling system is in normal
operation, the temperature setting of the chiller is at the value we
suggest, the connections of the water recycling are right. If you
troubleshoot the above problem, keep the cooling system operating until
Err 1
the water temperature is below 30℃, then restart the laser and check if
the High temperature error is eliminated. If the error remains, please
contact Raycus.
Low Temperature Error: First, check the environment temperature. If the
environment temperature is below 10℃, the laser may report 'Low
temperature error' in the first 10 minutes at cold start. Second, check the
water temperature of the chiller. If the water temperature is too low,
Low temperature error may be caused. Set the water temperature at
25℃, keep the cooling system operating until the water temperature is
above 10℃, then restart the laser and check if the Low temperature error
is eliminated. If the error remains, please contact Raycus.
Err 2 Reserved error code, undefined
Err 3 Reserved error code, undefined
Description：
Output Power Error, it occurs when the difference between output power
Err 4
and the setting output power is beyond the threshold we set, and the
laser will be stopped and locked. This error occurs only when the laser is
