Troubleshooting
Problem Solution
The key switch is on, but the system is
not ready. (Key Switch function enabled) Toggle the Key Switch.
The unit is in the Ready mode, but will
not respond to commands. The Interlock Switch is open.
Mod LOW is not properly grounded.
The Over Temp Light lights up. The cooling water is too hot for
operation. Improve cooling.
Laser power seems low. Possible RFPA malfunction.
Fault light is lit or blinking. The water flow is out of range.*
The airflow is out of range.
The DC voltage is out of range.
*If the water flow is in the right direction and flowing at the correct rate, but a water fault
still shows (see “Indicator Light Details” page 13) it is possible that the water flow
turbine is stuck. This can happen if the water is not clean or scale deposits built up. It
may be possible to remedy the issue with the following procedure:
1. Power down the laser and water supply.
2. Remove the water hose from the water flow turbine.
3. Using a straightened paper clip, gently reach into the turbine and nudge the rotor
so that it moves.
4. Check to see that there is no debris in the turbine.
5. Replace the hose and test laser.
Directional Coupler:
The laser interface connector provides signals that carry information about the RFPA
and the match to the laser. There are 2 independent RFPAs and 2 sets of directional
coupler signals. The reflected signals display the reflected RF power waveforms.
These lines are most useful in determining the quality of the match between the laser
and RFPA as well as indicating the proper operation of the laser. The forward signals
display the forward RF power waveforms. This line
provides a measure of the forward power level.
The expected waveforms for the Forward and
Reverse signals are provided here for a laser firing
at 25% duty. If the waveform amplitude for both
the forward and reverse signals are similar, it can
be assumed there is a problem with the laser.
