27.10 Reset an alarm message (E001–E599)
An alarm is output when a safety function is activated or if there is a hardware or system
error.
When an alarm occurs, laser pumping is turned off and laser radiation is stopped if marking
is in process. The corresponding error code is indicated on the LED display.
There are different methods to reset an alarm, depending on the type of error.
If the error persists after restarting the laser marking system, contact our sales offices or
representatives.
• Remove the cause of the alarm and confirm the operation logic of the safeguards.
• E001–E399: These errors are caused by hardware or system errors. Restart the laser
marking system to clear the alarm.
• For error codes E400–E599, reset the alarm by one of the following methods:
‒ Confirm the error message in Laser Marker NAVI smart to reset the error.
‒ Turn on the alarm reset input ALARM RESET IN (X15) on the TERMINAL connector.
‒ Send an Alarm reset (
ARS
) command.
• If a counter is used, check the counter value in the marking file before resuming the
marking process.
