•
After a quick initial blink, the status LED will blink steadily once the control box recognizes
the connection to the laser head. If the initializing LED does not come on immediately,
check the signal cable connection from the laser head to the back of the control box.
•
The status indicator LED notifies the following:
o
Starting- LED will blink slowly verifying laser emission.
o
Acquiring- LED will blink rapidly signifying warming up and/or attempting to lock.
o
Stable- LED stays on and does not blink meaning laser is locked in selected mode of
operation.
•
Ensure that no laser retroreflections enter the laser front bezel aperture during acquire.
•
If the status LED fails to indicate the acquiring status after one minute, the laser tube is not
igniting. Switch the control box off in this case, wait several minutes and retry.
BASIC TROUBLESHOOTING
Once the laser and control box have been properly connected, the stabilized laser system will
operate without maintenance. Below are some guidelines if your system is not operating.
•
No emission light above the key switch after key has been turned to the on position.
o
Verify that the power cord is connected to the back of the control box as well as a
verified power source.
•
System fails to enter acquire status.
o
Ensure that the remote interlock connector is well seated in the back of the control
box.
•
Status LED does not light.
o
Check the control cable connection from the laser head to the back of the control
box.
•
No laser emission.
o
Make sure shutter is open.
o
Verify that the high voltage cable is connected and well seated to the back of the
control box.
o
If laser does not ignite within one minute switch the control box off, wait several
minutes and retry.
•
LED indicator moves in and out of lock status.
o
Instability is usually caused by retroreflections entering the aperture of the laser
head. Close the shutter and verify whether the system re-locks. This will determine
whether retroreflections are causing instability in the system. When the shutter is
closed and the system remains locked, retroflections are causing the instability.
•
The specified ambient air temperature at which this system will operate is 15
C - 30
C.
Stability performance will be degraded if the system is operating at temperatures outside
this range. For optimal performance, laser must be in a draft free environment where the
ambient temperature remains constant and within the specified range (laser performance
is optimal in free convection).
