If the pins 6 and 7 are disconnected, the device will immediately interrupt the light, and the Yellow fault alarm lamp will be lit. Six and seven legs need to be short-jointed before the laser is emitted.CAUTION:4.4.2Control InterfaceFigure 8 shows a schematic diagram of the DB25 control interface.：Figuer 8: DB25 control interface.The DB25 behind the power module is the interface between the control system (such as marking machine) and the laser system. Be sure to connect reliably before working. The pins are defined as follows:Table 6: DB25 Control Interface Definitiona)The pump current of diode laser and the laser output power are controlledby setting the value of PIN1-PIN8 (TTL level). PIN1-PIN8 can be set from 0～255，corresponding to the laser output power from 0～100％(the actual laser power may not be strictly linear with the setting value). The relationship between PIN value and output power is shown in Table7:Table 7:Definition of power control PIN valueb)Pin 17 is an external 5V power input, which supplies power to the outputoptocoupler of the alarm signal; the input current is more than 20mA.c)The external input signals (Pin 1-8, 18, 19, 20, 22) of the laser are allconnected with optocouplers inside the system to ensure that the input level is high in the range of 3.3V-5V and low in the range of 1.7V. Pin input current is greater than 7 mA.d)Warning Signal Definition:Table 8 Warning Signal Definitionoptocouplers, and 17 pins 5V power supply is needed to get an effective signal.f)Note: The pre-output light signal (needle 18) must be at least 5 ms earlierthan the output light signal (needle 19), otherwise the laser will be damaged easily.Schematic diagram of input signal interface circuit：Figure 9: Schematic diagram of input signal interface circuitSignal input needs to be able to provide at least 7 mA of current. The schematic diagram of the output signal interface circuit is shown in Fig. 10.Figure 10: Schematic diagram of output signal interface circuit4.4.3 RS-232 Serial PortFigure 11 shows the RS-232 serial port schematic diagram.Figure 11 RS-232 serial port schematic diagram.The pins are defined as follows:Table 9 RS-232 PIN DescriptionRS232 interface is a special interface for Raycus internal personnel debugging.5Application Steps of Laser Device5.1 Pre-inspectiona)Check whether the size and connection of water pipe are correct, mainlyincluding water temperature, water flow rate, maximum input pressure,refrigeration capacity, whether the water cooler meets the systemrequirements (see Section 3.3 for details), whether the water cooler valve is opened, etc., to ensure that the water cooler is in normal working statebefore the laser is opened.b)Check whether the appearance of the laser device is normal and whetherthe output optical cable is bent or falling off.c)Check whether there is dust or other dirt in the protective lens of the outputoptical cable. Use compressed air to confirm whether it can be blown off. If not, wipe it gently with the lens paper dipped in alcohol, and then check itwith a special flashlight.d)Check whether the power supply and control signal of the laser areconnected correctly.e)Check whether the emergency stop switch is loose.5.2 Operational Stepsa)Start-up operation stepsPower on the laser, turn on the air switch, turn on the key switch (the keyswitch is turned clockwise to ON position, the power indicator lights up,indicating that the main control board has been powered on), wait 10seconds and then press the laser switch (the light of the indicator indicatesthat the power module of the laser has been powered on normally).b)Operational procedures for checking laser cleaning after laser is turned onWhen the device is started normally, the laser power will be increased from 10% to 100% when the laser is first tested. Watch whether the laser isgetting stronger and stronger as a cleaning material.5.3 Attention in the process of operationa)The repetition frequency range of the laser should not exceed 10-50 kHZ.b)Do not adjust the laser repetition frequency during marking.c)Turn OFF the laser until the power to zero, then turn off the laser powersupply, and finally turn off the water cooler.6Common Alarms and solutionsThe instructions and possible solutions of alarms are as follows:Table 10 Error instructions and possible solutionsIn addition to the above, if there are any other questions or errors, please contact Raycus to get help.7Warranty, Return and Maintenance7.1General WarrantyRaycus warrants that all Raycus fiber laser products are comformed to applicable product specifications under normal use and are free from defects in materials and work manship.The warranties start on the date of shipment from Raycus for a period of time as set forth in the applicable purchase contracts or product specifications.
