ERROR MESSAGES AND TROUBLESHOOTING
The POLYLASE LP Laser has a number of internal interlock circuits and sensors that
control the status of the laser. If the system detects an interlock error or inappropriate
value of the monitoring parameter, the Error Message will appear in the Message area on
the LCD display. The possible errors are divided into three categories:
SYSTEM/INTERLOCK ERRORS, SYSTEM FAULTS and LASER CONTROLLER
ERRORS
System/Interlock Errors
When the error of this category takes place, the following error messages are possible:

cleaner, if necessary.
System Faults
When the error of this category takes place, the system controller automatically turns off
the high voltage power supply, clears the LCD screen and displays corresponding error
message. This procedure takes place after each SYSTEM FAULT and does not depend
on the current system settings or operation mode. The laser operation can be resumed
only after complete system TURN OFF procedure and then turning it back on.
Note: Turning the system OFF using red Emergency Button is also considered by
controller as SYSTEM FAULT. To resume operation, the Emergency Button must be
released by pulling it up and the system must be turned back ON using the Key Switch.
If any system fault occurs, the following error messages are possible:
