173Error IndicationWhen an error occurs, an error code appears on the display panel of the laser marker.Errors are categorized into alarm and warning depending on their details.This chapter describes the details and measures of errors.Alarm: E001 - E599Errors that occur when highly emergent safety function is activated or there is any abnormality in laser marker are output asalarm.When an alarm occurs, the laser supply (laser pumping) is turned OFF, and the laser radiation is stopped if during thelasing process.⿎ Release method of alarm1. Remove a cause of alarm and confirm the safety. (Any alarms due to hardware’s problem cannot be released.)2. For error codes E400 to E599, use any of the following means to input the alarm reset.• Click the confirmation button in the error dialog on the configuration software Laser Marker NAVI smart screen.• Turn ON ALARM RESET IN (X15) on the I/O terminal block.• Use the serial communication (RS-232C or Ethernet) to transmit an alarm reset command (ARS).For the alarms you are unable to reset such as the ones caused by hardware or system error, restart the laser marker.3. If any alarm occurs during marking of files that use the counter, check the counter value before resuming marking.ERRORCODE Description Measures *1E001 - E038E045 - E094E101 - E138E145 - E194E202E208 - E214E223 - E224E230E245 - E248E300 - E380An error has occurred to the internal system ofthe laser marker.Check the connection of the cable and varioussignal lines, and then restart the laser marker.E039E044E139E144• Incorrect model combination of laser markingsystem.• Incorrect connection of signal cable or unitpower cable.• For LP-GS/RC/RF series, make sure thecorrect model numbers of laser head andcontroller have been connected.• For LP-RV series, make sure the correct modelnumbers of laser head, oscillator unit andcontroller have been connected. Connect theoscillator unit correctly to the laser head andcontroller.• Check the connection of the cable and varioussignal lines, and then restart the laser marker.E040 - E043E140 - E143E221 - E222E240 - E243• Incorrect connection of signal cable or unitpower cable.• An error has occurred to the internal system ofthe laser marker.• Check the connection of the cable and varioussignal lines, and then restart the laser marker.For LP-GS/RC/RF series, check theconnection between laser head and controller.For LP-RV series, check the connectionbetween laser head and oscillator unit andbetween oscillator unit and controller.• Replace the cable.E200 - E201*2 INTERLOCK safety relay is out of order.
