5.2. Before You Call
—Troubleshooting
If you are having a problem with your laser system, please check the list below of common
conditions that can occur that you may be able to resolve without having to contact Customer
Care.
The laser system will display error messages to caution the operator to fault conditions. If
any of the following errors occur, the laser system will remain in
Standby
mode, or return to
Standby
mode, produce an audible warning and display the related message describing the
fault condition. The following are examples of these fault conditions:
•
Optical fiber is not inserted,
•
Remote interlock is removed,
•
Finger switch is depressed.
To proceed, correct the error and press the
exit
button.
The system continuously monitors the output current of the diodes to ensure they are within
the factory calibration settings. If it is detected that the electrical current levels exceed the
upper or lower limits that would result in power levels outside of the ±20% thresholds, the
laser will stop emission and require system reset.
•
When the laser pulse rate is CW (Continuous Wave), the laser output power is the
same as the power setting on the display within operating tolerances.
•
When the laser pulse rate is not CW (e.g. 10 Hz), the average output power is 50% of
the power setting on the display, within operating tolerances.
The laser system will not enter or remain in
Emission
if the laser system is overheating. If
temperatures exceed safety limits:
•
There will be an audible warning.
•
There will be an error message: Laser temperature is out of range.
Press the
exit
button and reset the system. Make sure that the ambient temperature of the
laser system is within the operating temperature range of the device. If the problem still
exists, contact Customer Care for further troubleshooting.
If the laser system will not turn on:
•
Make sure that the power cord is correctly attached and plugged into a functioning
power outlet.
5.3. Calibration Check Procedure
The instructions below provide steps for performing a calibration “check” that may be
performed with certified, NIST traceable equipment. This procedure is recommended to be
performed once a year but is not required unless there is evidence of significant damage or
diminished output. If during the execution of this procedure, the stated requirements are not
met, then factory maintenance and re-calibration may need to be performed on the device.
Factory calibration must be performed by certified Service Personnel.
