I get a fault code 5 when the unit runs a self test. What does this mean? My unit only runs in CW mode, so I used to be able to switch it to CW after failing the self test. It doesn't work in Ultrapulse mode. I don't recall see the code 5 before, but it has been a while since we have turned on the laser. I don't have the manual for this laser. Thank you for helping.

Fault Code 5

there is no power detected on self test powerup.
FAULT 5 - NO LASER POWER DETECTED AT LIGHT OFF. The laser output, as measured via the
thermopile, indicates less than 4 watts (less than 800 mv at TP16 on controller PCB at tube light off). This test
is done during the first laser firing of the power up initialization and self test sequence. Check the output
coupler and shutter mirror for contamination/damage. Check for modulation signal to the RF exciter/
amplifier (TP1 on the controller), and the 48 VDC power supply output.
