Common Faults and Treatment
Various failures of the laser and possible solutions are as follows:
Number
Malfunction
Solution
1
PO indicator does
not light up
Check the voltage value of the input power supply and ensure that
the cable is connected accurately and reliably;
Restart the laser to try;
If the fault continues to occur, please contact Raycus.
2
TM/TE alarm
indicator is on
Check whether the cooling fan on the back of the laser is
operating normally;
Check whether the ambient temperature exceeds the usage limit;
If the ambient temperature meets the laser usage requirements,
shut down and cool down for a period of time, and restart the
laser to try;
If the fault continues to occur, please contact Raycus.
3
IN alarm indicator
is on
Check whether the Interlock pin is reliably shorted (please refer
to Table 3);
Restart the laser to try;
If the fault continues to occur, please contact Raycus.
4
LD alarm indicator
light is on
Restart the laser to try;
If the fault continues to occur, please contact Raycus.
5
Laser does not
emit light
Check whether the LA signal light is on;
Check whether the SI signal light is on. If it is not, check the
external input signal (refer to the description of SI signal light in
"3.1 Front Panel Function") to ensure that the signal is input
