General Safety Instructions

In order to ensure the safe operation and optimal performance of the product, please follow these warnings and cautions in addition to the other information contained elsewhere in this document.

Specular Reflection

There are often numerous secondary laser beams produced at various angles in the output port of the laser. These divergent beams are produced when the primary beam of laser reflects off a smooth surface, and they are called specular reflections. Although these secondary beams may be less powerful than the total power emitted from the primary beam, the intensity may be great enough to cause damage to the eyes and skin as well as surface of materials.

WARNING :

You must exercise caution to avoid/minimize specular reflections as these laser radiations are invisible!

Safety Instructions of Accessories

WARNING :

This device has an output optical head connected to the laser by a fiber cable. Please, be careful dealing with the output head.

Optical Operating Instructions

We strongly recommend that you read the following procedures before operating the laser:

  1. Never look directly into the laser output port when the power is turned on.
  2. Avoid positioning the laser and all optical output components at eye level.

  1. Pin 18 is the Master Oscillator (MO) signal. The MO should be switched ON at least 5ms earlier than the Booster (BS) is switched ON. Once the MO is switched ON, the laser starts to consume more electrical power.
  2. Pin 19 is the Booster control input. HIGH means switching the BS on and LOW means switching it OFF. The laser starts to emit light within specified delay time after the pin 19 is set HIGH and stops emitting when the pin 19 is set LOW.100-300 watt PULSED FIBER LASER
    CAUTION :The MO should be switched ON at least 5ms earlier than the BS is switched ON. The laser does not start to emit if you switch the BS ON while the MO is LOW/OFF.If the MO is switched ON later than the BS is switched ON, the laser will emit about 1ms later than the switching of the MO. It is abnormal operation which should be avoid and not listed in the user guide. The BS switches ON simultaneously with the rising edge of the signal applied to the pin 19.
  3. Pin 20 is the Synchronization input. Pulse train with a repetition rate (PRR) within specified operating range should be applied to the pin 20 (refer to the optical specification for PRR limits). The laser emits pulses simultaneously with the rising edge of the signal.
    CAUTION:If the PRR is out of the specified range (or no PRR signal is supplied) the laser safety circuit will substitute the missing pulses or limit the PRR.The laser emission is not allowed simultaneously with the guide laser. The BS is blocked internally during the guide laser operation. If pin 19 is set HIGH but the guide laser is on, the laser will not emit light, unless the guide laser is switched OFF. The MO is able to be switched ON or OFF during the guide laser is ON.
  4. Pin 23 is the “Emergency stop” input. It should be set to HIGH for normal operation. In case of dropping this pin to LOW state (even for a short period of time), the laser automatically switches OFF (similar to the state when both MO and BS are OFF). It is necessary to drop both MO and BS to LOW (if they were HIGH) before restarting the laser.

Laser Operation Using Digital Interface

Operation Steps

  1. Remove the protection cap from the laser output optical head.
  2. Connect the laser module to the control system via DB-25 connector. Use pins according to the description above. Refer to 5.2.2 Digital Control Interface (DB-25) Description.
  3. Recommended initial state of control pins:
    Pins 18,19 LOWPin 20 With repetition rate within the specified range
  4. Set ” Emergency Stop Input ” (Pin23 ) High
  5. Set desired power via pin 1-8.
  6. Switch MO ON applying HIGH to the pin 18.
  7. Wait 5ms.
  8. The laser can be fast modulated via Pin 19 and the laser state of ON or OFF can be set with a HIGH or LOW input signal respectively. Switching ON/OFF of the laser has a finite rise/fall time (refer to the specification for the particular model). The time of the modulation should not be less than the sum of rise and fall times, otherwise laser optical response may not be as expected. The typical rise/fall times are 250us, so the modulation period should be greater than 500us (correspond frequency is 2kHz)
  9. If the next operation time between subsequent ON/OFF batches (jobs) is more than 20ms, it is recommended to switch OFF the MO. This will reduce the power consumption, avoid unnecessary aging of the laser and eliminate the residual MO power at the laser output.
  10. After finishing the laser operation, switch OFF the BS and MO (set LOW to pin 19 and pin 18).
  11. Remove all supply voltages.

 

Operation Features

  1. PRR can be changed during laser operation with the adjustment of the signal frequency at the pin 20.The time between two adjacent rising edges should be within the specified range of PRR period. It should be less than 50 us when the laser is operated at the minimum PRR of 20 kHz. If the PRR (pin 20) is higher than the upper limit, the laser will be operated at the maximum specified PRR. If the PRR (pin 20) is lower than the minimum allowed PRR, the laser will be operated at the minimum specified PRR.
  2. The power setting can be changed during the laser operation by applying updated values to pin 1-8 and latching them into the laser via pin 9. The laser will respond to the changes on the subsequent specified rise time.
  3. If pin 18 is HIGH and pin 19 is LOW, there is laser radiation with the power of less than 20mW.
  4. If the temperature of the laser module exceeds +45℃ , the laser will be automatically switched OFF and the alarm signal will appears on pins 16 and 21. Even if the temperature drops back to under +45 ℃ , the laser will not resume the emission and keep the alarm pins unchanged until it is re-started.

Common Fault Treatment

Laser Emission Failure

  1. Make sure the connection of power supply is correct.(+220/110 VAC and GND connect correctly? Earth the ground wire?)
  2. Make sure the E-STOP switching is released, Emergency Stop Input is high when the laser is in normal operation.
  3. Make sure the power supply is in normal condition, and check its output without and with load( connected with the laser).
  4. Software set correctly.
  5. Interface DB-25 connect correctly under specified guide.
  6. Normal Signals of Pins 18 and 19.
  7. Normal signal and supply power of control card(please refer to 5.2 DB-25 control interface pin function).
  8. Make sure the guide light signal is LOW during marking (Pin22 is “0”). The device’s first priority is to emit the guide light when the guide signal is HIGH.

Power Drops

  1. Check whether the power supply output steady, and the current is at its rated value.
  2. For collimated outputs, maintaining a clean output lens is essential, Cleaning with lens tissue is allowable as required. Do not scratched film layer. galvanometer, field lens.
  3. Inspect whether other optical lens are clean, such as red light combiner,
  4. Inspect whether optical output is uncovered, isolator output terminal and galvanometer are at grade.
  5. Normal loss of power from using for 20,000 hours.
  6. There may be breakage while marking resulted from by signal interference or ground connected incorrectly. The leads of weak and strong current cannot be linked together or at the same side. Use the signal wire with shielded function.
