OTHER LASER FAULTS PAGE | 95
Possible Causes:
•
The remote interlock circuit momentarily opened.
Remote interlock faults are not latched on OEM lasers. This means that if an interlock open fault occurs,
the Remote Interlock indicator will turn red, the Interlock Open output will Close, the Ready light goes out,
and lasing is disabled. However, if the interlock circuit closes, the Remote Interlock indicator will change
from red to green, the Ready light illuminates, and five seconds later lasing is enabled.
Symptom:
•
There is no output laser beam, and all LED status indicators are Off
Possible Causes:
•
The 20 A fast-acting fuse has blown.
Remove DC power from the laser and then check each fuse on the rear panel. Replace as required using
only a Bussman ABC-20 or equivalent.
Symptom:
•
There is no output laser beam from your f201 laser, but status indicators appear as:
Remote Interlock LED – Green Interlock Open output – Open
Temp LED – Green Over Temperature output – Open
Ready LED – Off Laser Ready output – Open
Lase LED – Off Laser Active output – Open
Possible Causes:
•
One of the two 20 A fast-acting fuses has blown.
On f201 lasers, a single blown 20 A fuse on the laser’s rear panel may cause the Ready lamp to remain Off
while other LEDs indicate normal status. Remove DC power from the laser and then check each fuse on
the rear panel. Replace as required using only a Bussman ABC-20 or equivalent.
