F59 - SYSTEM DATA INCORRECT - This check is done during self test only. There is a disagreement the
software EPROM version installed and the information on EPROM software version stored in NVRAM.
F60 - ENERGY MONITOR ERROR - The safety processor and main processor have had a conflict in the shared
use of the energy monitor circuits. Replace the CPU PCB if the fault persists.
F61 - PROGRAM FLOW ERROR - Replace the CPU PCB if this fault persists.
F62/63 - ENERGY 20% HIGH/LOW - (information only, active in service mode)
F64/65 - RATE 20% HIGH/LOW - (information only, active in service mode)
F66 - FRONT PANEL COMMUNICATIONS TIME OUT - The front panel has not responded in time to a query
from the main processor.
F67 - SOFTWARE TIMING - A firing pulse has been missed because the software did not complete all the tasks
necessary in time for the correct pulse interval.
F68 - BLAST SHIELD IS NOT INSERTED - The microswitch that detects the blast shield position is indicating
that the blast shield is not inserted.
F69 - ONE OR MORE FLASHLAMPS NOT LIT - (permanent, active in service mode)
F70 - NOFIRE TEST FAILED - (pemanent, active in service mode)
F71 - AUTOCALIBRATION DISABLED - SW3 is in the down position.
F72 - SERVICE ATTENUATOR IN THE BEAMPATH - The service attenuator is energized. The service
attenuator is controlled by a switch mounted on the Shutter PCB.
F77 - LOW ENERGY ATTENUATOR COATING DAMAGED - With the low energy monitor in the beam path,
the energy measured at the low energy attenuator output is not 40% of the energy measured at the input. Press
READY to clear this fault.
F78 - THE SYSTEM TRIED TO FIRE THE WRONG LASER - Press READY to clear this fault.
F79 - OVERTIME - A timed exposure exceeded its time limit. Press READY to clear this fault code.
F80 - ATTACH HOLMIUM FIBER - Holmium is selected, but the fiber attached is not recognized as the smart
fiber (Hall effect does not sense magnetic field).
F81 - LOW ENERGY ATTENUATOR NOT IN CORRECT POSITION - The position sensors (slotted optical
switches) indicate the low energy attenuator is not in the correct position. Press READY to clear this fault code.
F82 - FAILED TO DETECT A FORCED OVER EXPOSURE - Detected during self test. Restart the system to clear
this fault code.
