Renuva没有激光输出排查思路—中英文版


应用本文的前置条件:
1、Renuva的工作过程正常,没有其他报警;
2、扫描振镜工作正常;

Step 1. 检查激光器风扇
   上电开机,进入工作界面,按下Ready按键,此时激光器开始工作,激光器风扇会发出非常明显的风噪;

a. 如果激光器风扇有风噪,检查DB25接头是否脱落(激光器-主控板),如无问题,则检查指示灯(Step 2);



















b. 如果激光器风扇没有风噪,则检查激光器供电(Step 3);

Step 2. 检查激光器指示灯
   需请专业工程师拆开机壳如何拆除机壳,并上电工作,在踩下脚踏开关时,观察激光器的两只绿色LED等的情况
Ready状态下,没有踩下脚踏开关时,两个LED常亮;踩下脚踏开关出光时,下面的LED会闪烁一次;
如果LED灯长亮,不闪烁,则需检查控制线是否虚接;
如果LED灯不亮,需检查激光器供电(Step 3)
如果LED工作正常,判断激光器损坏;



Step 3. 检查激光器供电
需用万用表直流电压档检查MSP-300-24的输出端是否为24V;
如果有24V电压,说明激光器供电正常,则判断为激光器损坏;
如果没有24V电压,需检查主控板D16指示灯是否点亮;
如果D16不亮,判断为主板损坏或继电器短路;
如果D16点亮,进一步检查P9-1和P9-2是否高电平(电压在10V-12V之间);如果是高电平,表示MSP-300-24的供电继电器已吸合,此时需检查相关线束和接头是否有虚接情况;如果是低电平,表明继电器并未吸合,可检查P9接口到继电器之间的线束是否虚接,如果没有虚接可判断为主板故障;
给激光器供电的直流电源V+和V-之间电压是否24V











Renuva has no laser output

Apply text preconditions:
1、Renuva's work is normal and there are no other warning;
2、The scanning galvanometer works normally;

Step1. Checking the laser fan
     Power on and start up, enter the working interface, press the Ready button, then the laser starts to work, the laser fan will emit very obvious wind noise;
1. If there is wind noise in the laser fan, check DB25 connector lose or not, then check the indicator (Step 2);



















2. If the laser fan has no wind noise, check the power supply of the laser (Step 3);
Step2. Checking the laser indicator
     Need to ask a professional engineer to disassemble the shell Renuva shell removal procedure, and power on the work, when stepping on the foot switch, observe the two green LED laser
In Ready state, when the pedal switch is not pressed down, the two LEDS are steady on; Step on the foot switch light, the LED below will flash once;
If the LED light is long on and does not blink, check whether the control line is virtual connection.
If the LED lamp is not on, check the power supply of the laser (Step 3)
If the LED works normally, judge the laser damage;
 

     






Step3. Checking the power supply of the laser

Use a multimeter to check whether the OUTPUT end of  MSP-300-24 is 24V;
If the voltage is 24V, the power supply of the laser is normal, and the laser is judged to be damaged.
If the voltage is not 24V, check whether the D16 indicator on the main-board is on.
If D16 is not on, it is judged that the mainboard is damaged or the relay is short-circuited.
If D16 is turned on, further check whether P9-1 and P9-2 are high (voltage between 10V-12V); If it is high level, it indicates that the power supply relay of MSP-300-24 is closed. In this case, it is necessary to check whether the relevant wiring harness and connector have virtual connection. If it is low level, it indicates that the relay is not closed. Check whether the wiring harness between the P9 interface and the relay is virtually connected. If there is no virtual connection, it can be judged that the main board is fault.

Whether the voltage between THE DC power supply V+ and V- for the laser is 24V
