When cleaning, please keep the distance from the gun head to the plate stable and keep the hand speed even.

Laser usage instructions

Laser protection requirements

Laser safety glasses should be selected based on the standard that they can shield the laser light within the entire wavelength range emitted by the laser. When operating laser equipment, please choose safety glasses appropriately based on the laser wavelength emitted by the laser equipment and ensure to wear them at all times. If the device is a laser tunable or Raman product, it will emit laser light beyond the normal output wavelength range of the device's laser, and corresponding safety protection must be implemented during protection.

General safety instructions

1. Specular reflection

The position of the laser output port may generate secondary laser beams and radiate outward at multiple angles. This phenomenon of divergent beams produced after the main beam of the laser is reflected on a plane is called specular reflection. Although the energy of the secondary laser beam is much smaller than that of the primary laser beam, this intensity may also cause damage to human eyes, skin or some material surfaces.

Warning:

● Since laser radiation is invisible, you must operate with extreme caution to avoid or reduce specular reflection.

2. Safety instructions for accessories

Photosensitive components integrated into laser-related optical accessories may be damaged by laser exposure, such as video cameras, photomultiplier tubes, and photodiodes. Pay attention to relevant device protection.

Warning:

● The output laser intensity of Chuangxin Laser MD-dual-wavelength direct semiconductor series laser is enough to melt metal, burn skin, clothing and paint, and ignite volatile substances such as alcohol, gasoline, ether, etc. Therefore, during operation and use, be sure to isolate flammable items around the laser.

3. Instructions for optical operation

It is strongly recommended that you read the following operating points before operating the laser:

(1) When the power is turned on, do not look directly into the laser light outlet;

Notice:

● Generally, when the laser is in use, its optical path output head will be connected to a lens with an enhanced transmittance coating before emitting. If your laser's rear optical path has this kind of optical lens, please check the laser output before using the laser. Strictly inspect the first lens and rear lens to ensure that there is no dust or any other debris on the lens. Any attachment visible to the naked eye will cause serious damage to the lens, leading to burning of the laser or any subsequent optical path equipment.

● Please refer to the "Fiber Optic Connector Inspection and Cleaning Guide" to follow the lens cleaning inspection process.

● Please be careful of the scorching heat or molten metal particles that may be generated during laser welding operations.

● When debugging and calibrating the laser output, it is necessary to set the laser to detect the spot quality of the laser output via infrared under low power output conditions, and then gradually increase the output power.

Warning:

● Reasonably select safety protective equipment based on the output power and wavelength requirements of the laser.

● Do not look directly at the optical fiber or collimator, and make sure to always wear safety glasses during each operation.

Water tank instructions

1. Overview

This product is an industrial cooling device designed and manufactured for laser cutting, laser welding, laser marking, laser engraving and other equipment that uses laser processing. It can provide a cooling medium with stable temperature for the above application scenarios.

The chiller is composed of a compressor, a condenser, a throttling device (expansion valve or capillary tube), an evaporator and a water pump. Its working principle is that the water is cooled by the refrigeration system of the chiller, and the low-temperature cooling water is sent by the water pump. The cooling water takes away the heat, heats up, and flows back to the chiller. It is cooled again and then transported back to the equipment. In the refrigeration system of the chiller, the refrigerant in the evaporator coil vaporizes into steam by absorbing the heat of the return water. The compressor continuously extracts the generated steam from the evaporator and compresses it. The compressed high-temperature and high-pressure steam is After being sent to the condenser, it releases heat (the heat is removed by the fan) and condenses into a high-pressure liquid. After being decompressed by the throttling device, it enters the evaporator, vaporizes again, and absorbs the heat of the water. This cycle repeats over and over again. The user can use the thermostat to Set or observe the water temperature working status.

2. Appearance and component names

Note: The above appearance and component names are only for one of the models. The appearance and component locations of different models will be slightly different.

3. Install

1. Open the package and check whether the machine is in good condition and whether the accessories are complete.

2. Please ensure that the working voltage of the water chiller is stable and normal.

Since refrigeration compressors are sensitive to power supply voltage, the normal working voltage of our company's standard products is 210~240V (110V model is 100~120V). If you really need a wider operating voltage range, you need to customize it separately.

3. Equipment installation conditions and requirements.

(1) It must be installed horizontally and cannot be tilted.

(2) When using the machine, please ensure that the casters are locked to prevent the machine from slipping during operation. The brake device is generally installed on the wheel sleeve or wheel surface, and can be stepped on by hand or foot. When pushing the machine, the wheel cannot rotate, but it can turn, which means the brake is correct.

(3) The air outlet on the top of the chiller must be at least 1.5m away from obstacles, and the air inlet on the side must be at least 1m away from obstacles (see the figure below).

(4) It must not be installed in harsh environments such as corrosive, flammable gases, dust, oil mist, conductive dust, high temperature and humidity, strong magnetic fields, direct sunlight, etc.

(5) Environmental requirements

(6) Media requirements

Cooling media allowed for the chiller: purified water, distilled water, high￾purity water and other softened water. It is prohibited to use oily liquids, liquids containing solid particles, corrosive liquids, etc. Clean the filter element and replace the cooling water regularly (recommended about three months) to ensure the normal operation of the chiller.

When the ambient temperature is lower than 2℃ and the chiller is stored with water, antifreeze needs to be added to the water tank of the chiller. It is recommended to add antifreeze containing ethylene glycol and propylene glycol with a concentration of no more than 30%. After the temperature warms up, change back to pure water, distilled water and other media, let the chiller run for 30 minutes to remove the residual antifreeze, and then add new circulating water for use after emptying.

4. Determine the direction of the pipeline layout according to the equipment inlet and outlet signs, and ensure that the water pipes are clean and free of impurities to prevent impurities from entering the water lines and causing blockage or water pump failure.

The inlet and outlet pipes are labeled and distinguished by color. The diameter of the pipe is 6*4mm. The transparent blue pipe is the high-temperature end outlet, and the transparent pipe is the high-temperature end return pipe. The diameter of the pipe is 12*8mm. The transparent blue pipe is the low￾temperature end outlet. It is transparent. The pipe is the low temperature end return pipe.

5. Plug in the power cord and turn on the power switch (it is strictly prohibited to start without water).

(1) After turning on the power switch, the chiller circulation pump starts to work. When a new machine is started for the first time, there will be a lot of bubbles in the pipeline, causing the machine to occasionally generate a flow alarm. It will return to normal after a few minutes of operation.

(2) After starting the machine for the first time, you must immediately check whether there is any leakage in the water pipes.

(3) After turning on the power, if the water temperature is lower than the set temperature, it is normal for the machine's fan and other components to not work. The thermostat will automatically control the working status of compressors, solenoid valves, fans and other devices based on the set control parameters.

6. Electrical connection.

(1) When wiring, please conduct wiring according to the maximum rated current on the label of the chiller.

(2) Recommended reference standards for power supply wire diameter selection.

Note: This data is provided in accordance with the IEC 60204-1 standard and is for reference only. The power cord must use a standard cable.

(3) The main circuit of the power supply must be equipped with appropriate leakage and overload protection devices, and ensure that the chiller is well grounded.

(4) The power supply voltage is allowed to fluctuate less than ±10%, the frequency fluctuation is less than ±1Hz, and it should be kept away from electromagnetic interference sources.

7. Add water to exhaust:

(1) Add water

After the new machine is started, the air in the water pipe is emptied, and the water level in the water tank will drop slightly. In order to keep the water level in the green zone, you can add an appropriate amount of water again. Observe and write down the current water level, and observe the water level gauge again after the chiller has been running for a period of time. If the water level drops significantly, check again for leaks in the water pipes.

(2) Exhaust

After adding water and replacing new water for the first time, drain the air from the water pump before starting it, otherwise the equipment will be damaged.

Method 1: With the machine turned off, add water, remove the low￾temperature water outlet (OUTLET L), connect it to the water pipe, drain it for 2 minutes, and then install it firmly.

Method 2: Open the water injection port, turn on the machine (water flows), and repeatedly press and fold the water pipe several times to drain the air inside the pipe.

8. Inspection before test.

(1) Check whether the pipeline connections are correct and there should be no bubbling or leaking;

(2) Check whether the drain outlet is closed;

(3) Check the water tank level;

(4) Confirm that the electrical wiring of the equipment is connected correctly;

(5) Confirm whether the equipment is grounded.

When the ambient temperature is lower than 2℃ and the machine is shut down for a long time, the internal water must be drained.

Regularly disassemble the dust filter, clean it and use a compressed air gun to blow away the dust accumulated on the condenser (it is recommended to take about a week, and the dust filter must not be missing for a long time).

Maintenance and replacement methods of related lenses:

① Before operation, please clean and dry your hands, then wipe your hands again with cotton dipped in alcohol.

② Open the protective lens and focusing lens compartment cover in a relatively dust￾free place, pull out the lens holder, protect it (cover it with masking paper), and check the protective lens. If there are obvious burning spots on the lens surface, replace it directly.

③ Then check the white power sealing ring under the lens. (If the power sealing ring is scratched or deformed, it cannot be used and must be replaced immediately.

④ Wipe the mouth of the compartment and the inside of the compartment cover with a cotton ball dipped in alcohol, quickly insert the protective mirror bracket into the protective mirror compartment, and tighten the screws.

Common exception handling:

Prompt laser/water cooler/air pressure alarm

① If the above alarm occurs without using the alarm signal, please change the alarm level on the screen settings page.

② If the above alarm occurs when an alarm signal is used, check whether the alarm of the corresponding device or the high and low levels of the alarm signal are set incorrectly. Screen does not light up/no response when clicking

① The screen does not light up. Make sure the controller is powered on. Check whether the four-core wire between the controller and the screen is connected correctly, and whether the 24V voltage at pin 1 and pin 4 is normal.

② If the click fails during normal use, check whether the temperature of the whole machine is too high.

③ If the click cannot be entered, check whether the four-core cable between the controller and the screen is connected correctly.

④ If the newly installed device does not respond to clicks, it may be that the system version does not match. You can use the SD card to re-flash the program.

No light

① Check whether there is an alarm prompt on the homepage and whether the laser enable is ON;

② During cleaning, check whether the trigger signal and safety lock signal on the monitoring page are displayed in green;

③ During cleaning, check whether the PWM, laser enable, and analog output on the monitoring page are normal.

If the above status is normal, please check whether the laser has any abnormal alarms.

For example: If the air is released and the wire is fed but no light is emitted, it means the laser is faulty or the laser wiring is wrong. If neither air is released nor wire is fed, the input signal may be missing.

Light output suddenly stops during processing

Check whether the safety lock and other alarms on the monitoring interface are normal.
