Possible Causes:
•
An over temperature condition has occurred.
On earlier OEM lasers (v40 versions B and C), over temperature faults are not latched. This means if an
over temperature condition occurs, the TMP indicator will turn red, the Over Temperature output will
Close, the RDY light goes out, and lasing is disabled. However, if the laser cools down enough to clear
the over temp fault, the TMP indicator will change from red to green, the RDY light illuminates, and five
seconds later lasing is enabled.
•
The remote interlock circuit momentarily opened.
Remote interlock faults are not latched on OEM lasers. This means if an interlock open fault occurs, the
INT indicator will turn red, the Interlock Open output will Close, the RDY light goes out, and lasing is
disabled. However, if the interlock circuit closes again, the INT indicator will change from red to green,
the Interlock Open output will Open, the RDY light illuminates, and five seconds later lasing is enabled.
Symptom:
•
There is no output laser beam; all LED status indicators are Off.
Possible Causes:
•
No DC voltage is applied, or the laser’s in-line fuse has blown.
Ensure that DC power cable connections are tight and verify that +30 VDC is available on the power
supply terminals under full load.
Check the in-line fuse on the laser’s red DC power cable. Install a Bussman KLK25 or equivalent 25-am-
pere fast-acting replacement fuse.
