Laser switch was not opened. There is the button of laser switch on face plate, by go down to be, bounce to close. Smooth road slants. Such problem also can appear below the case with the bigger range that slants in smooth road (slant solely namely beyond lens) . Had told in front about the adjustment of smooth road, did not say more in this, before reference explain tone to be rectified can. By the operation face plate checks key view to check ammeter status: Do not have electric current: Whether does power source of examination laser power source put through, whether the high tension line becomes loose or fall off, whether does line become loose; Have electricity: Examination lens is smooth whether serious deflection. Whether is system of examination boiler circulation illogical normally water: Whether doesn't examination water-cooling machine have electrify or attaint; Connect water: Whether does examination water inlet, mouth giving water accept Nor conduit crack. Can fixed fire, can self check, send data not to give off light (examination computer setting is proper) attaint of 　 laser power source: After giving laser power source power supply, see fan whether move normally, if move out of order, show laser power source to appear problem. This is to need to change power source. The definition of each horn of line of power source data: (for 100W the following laser provides commonly used power source) 1 foot of 　 　 is H (TH) input signal, the control of switch light, tall n (3V) when give light, low n (0.

3V) when do not give light; 2 feet are L (TL) input signal, the control of switch light, tall n (3V) when give light, low n (0.

3V) when do not give light; 3 feet are P (WP) input signal, the control of switch light, tall n (3V) when give light, low n (0.

3V) when do not give light; 4 feet are G signal ground, this foot must be linked together with the ground of the housing of laser machine, control plate; 5 feet input signal for IN, the control of laser power is carried, the imitate signal of usable 0-5V is controlled, the PWM signal that also can be amplitude with 5V is controlled; 6 feet output power source for 5V, its are the biggest output electric current is 20mA. If be mixed in 5 feet,join among 6 feet a resistor, can increase the electric current of laser, enhance the power of laser; 7 feet are the ground wire of laser power source; 8 feet are the negative pole of laser power source; 9 feet are the anode of laser power source; Detect first, whether does MPC6535 board card provide signal, when letting laser give light continuously, with avometer (the anode of avometer is put in tall n to input signal on 1 foot, negative pole is put on 4 feet ground wire) , 1 foot and laser control signal of input of test tall n signal 3 feet, see the tension on avometer, if voltage is far,be less than 3V, criterion MPC6535 board card cannot provide signal. If above without the problem, can detect water-cooling protects a line, mix 3 feet 4 feet are short receive, open laser to look to whether laser is outputted (open laser right now, must open water-cooling opportunity, let be in charge of refrigeration to laser, can damage laser is in charge of otherwise) , if have, the line that shows water-cooling machine has a problem, the water-cooling below the examination protects a line to whether can have the place with bad contact. If above do not have a problem, whether is the socket of line of data of the laser below reexamination contacted good. The definition of each horn of line of power source data: (the laser of 100W above provides commonly used power source) 1 foot of 　 　 outputs power source for 5V, its are the biggest output electric current is 20mA; 2 feet are H (TH) input signal, the control of switch light, tall n (3V) when give light, low n (0.

3V) when do not give light; 5 feet are G signal ground, this part must be joined with the ground of the housing of laser machine, control plate; 6 feet input signal for IN, the control of laser power is carried, the imitate signal of usable 0-5V is controlled, the PWM signal that also can be amplitude with 5V is controlled; Detect first, whether does MPC6535 board card provide signal, when letting laser give light continuously, with avometer (the anode of avometer is put in tall n to input signal on 2 feet, negative pole is put on 5 feet ground wire) , 2 feet and laser control signal of input of test tall n signal 4 feet, see the tension on avometer, if voltage is far,be less than 3V, criterion MPC6535 board card cannot provide signal.
