5.Troubleshooting and Maintenance

5.1What should Ido if the laser does notemit laser?

·Check whether the chiller is running or not and whether the set temperature is correct or not. · Check whether the water pressure protection line is connected.You canuseamultimeter to measure whether the water pressure signal line is normal. (Note:This laser does not alow water pressure protection short circuit.This machine is differentfromordinary machines.As longas there isno water, the machine willbedamaged,causing huge losses. Damage caused by this reason is not covered by the warranty.)

· The cooling power of the chiller is too small to keep the laser at 2 5 ^ { \circ } \mathsf { C } ,and the temperature fluctuates greatly. ·The powersupply is on oroff,the red indicator lighton the lasershould be onafter the power supply is on. ·Whether thesystem has enteredthe working state ornot,ifthe lasersystem isready,thegreen indicatorlights on before the laser can work normally.

· Check whether the control signal is correct or not;whether a \mathsf { C O } _ { 2 } control board is used or not,be aware that the fibercontrolboard cannotcontrolthelaser;if thecontrolboard isconfirmedtobecorect,pleasecheckwhether the "PWM ^ + signal"and "On/Offoptical signal"are connected correctlyornot.Usea multimeter to check:switch the multimetertotheDCvotage,setthepowerto"50"onthemarking software,and thenperformcontinuous marking.Atthistime, thePWM ^ + signal should haveavoltage outputof about 2.5V,and the“On/Offoptical signal"voltage should be 5V,and thenset thepowerfurther to"90"tocontinuousymark.At this time,thePWM+signalshould haveavoltageoutputof about4.2V,andthe“On/Offopticalsignalvoltageshouldbestill5V,whichmeans thesignalisnormal.Ifanoscilloscope isavailable,it ismore accurate to usean oscilloscope to do the check

·Check whetherthe terminalsofthesignal cableare soldered correctlyornot.The4-pinof the lasertobeconnect
edto theGNDof the controlboard;the5-pinto connectedto thePWM+signalof the control board,andthe7-pin
connected to the On/Off optical signal of the control board. · Check whether the plug of signal cable is firm or not.

5.2The laser intensity becomes weak after working fora period of time?

· Whether the chiller is on or not.
·Whether the working temperature is normal or not.
·Whether the water level of the chiller is too low or not.
·Whether the field lens and galvanometer are polluted or not.
