LASER FAULTS

Laser faults
v40 lasers version D and above (KFD, SAD, etc.) can indicate four specific fault conditions. In the event
of a certain faults, the RDY LED on the laser will blink an error code, pause four seconds, and then repeat
the error code. This sequence continues until the fault is corrected and the laser is reset by cycling DC
power to the laser.
Table below lists error codes, the corresponding fault condition, and describes any corrective action
possible in the field.

Resetting faults

Keyswitch lasers
Remote interlock fault
A remote interlock fault occurs when the Remote Interlock input opens (the INT indicator changes from
green to red). To reset a remote interlock fault, close the interlock input (INT indicator changes from red
to green) and cycle the Keyswitch from OFF to ON (or apply a ±5–24 VDC Remote Reset/Start Request
pulse with the Keyswitch set to ON). When the RDY indicator illuminates, lasing is enabled after a five-
second delay.
Over temperature fault
Over temperature faults occur when thermal limits in the laser are exceeded (the TMP indicator changes
from green to red). To reset an over temperature fault, lower coolant temperature below 22 °C (water-
cooled) or below 40 °C (air-cooled), cycle DC power to the laser, and then cycle the Keyswitch from
OFF to ON (or apply a ±5–24 VDC Remote Reset/Start Request pulse with the Keyswitch set to ON).
When the RDY indicator illuminates, lasing is enabled after a five-second delay.
