Wuhan Raycus Fiber Laser Technologies Co., LtdUser Guide RFL-A2000D-3000D Ver.1.032For 60% output power, type in 60.If you input a value out of the range specified in the brackets, the system will instruct youagain to input a legal value. Just follow the instructions.When the parameters are set and laser emission is enabled (“LASER” on front panel ispressed down or “LAS_C” is high), the laser emits sequence of pulses you have customized. The“MODULATION” cable is also left disconnected in this mode. CW mode with remote modulation and Pulse mode with remote modulationPress “3” in the mode selection page to enter “CW mode with remote modulation”, andpress “4” to enter “Pulse mode with remote modulation”. In these two operation modes, theparameter settings are no different from “CW mode” and “Pulse mode”. Only one more emissioncondition is added-remote modulation signal. So you must connect the “MODULATION” cableto remote modulation signal. Notice that the modulation signal is 24V level, and active high.When the parameters are set, laser emission is enabled (“LASER” on front panel is presseddown or remote emission control is sent from “LAS_C”), and the remote modulation signalinputs from “MODULATION”, the laser emits. Clear errorsPress “5” in the mode selection page will clear error records. Then press “7” to return.Error records are clearedPress ‘7’ to return to previous menu Save system configurationsThis operation is for Raycus personnel only.4.8 RS-232 ModeRS-232 mode is a remote control mode. In this mode, we have a protocol forcommunication between the laser and the upper computer, and you can set emission parametersand return errors. Notice that the “LASER” button or “LAS_C” is of no use in this mode, butmake sure to keep the button up and left “LAS_C” disconnected.
