Danger
serious
personal
injury
This Class 4 laser product emits
invisible infrared laser radiation in
the 10.6 µm CO
2
wavelength band. Since direct or diffuse laser radia-
tion can inflict severe corneal injuries, always wear eye protection
when in the same area as an exposed laser beam. Do not allow the
laser beam to contact a person. This product emits an invisible laser
beam that is capable of seriously burning human tissue.
Always be aware of the beam’s path and always use a beam block
while testing.
Warning
serious
personal
injury
Remote interlock faults are not latched on Firestar i401 OEM lasers.
Clearing the fault condition re-enables the
RDY
indicator and the la-
ser will fire after the five-second delay provided the
SHT
indicator is
lit and a PWM Command signal is applied. Because exposure to 10.6
µm CO
2
laser radiation can inflict severe corneal injuries and seri-
ously burn human tissue, the OEM or System Integrator must ensure
that appropriate safeguards are in place to prevent unintended lasing.
Important Note:
For safety reasons, the Firestar i401 laser contains an internal electromechanical
shutter assembly that is controlled by the
Shutter Open Request
input signal (Pin
10 on the DB-15
User I/O
connector). The shutter opens only when a
Shutter
Open Request
signal is applied
and the
RDY
LED is on (
Remote Interlock
input
active and no over-temperature fault exists).
Use the interlock input to provide maximum operator safety. When the
Remote
Interlock
input is opened (voltage source removed), the internal shutter automati-
cally closes to block the beam path, the
RDY
LED turns Off, the
SHT
LED turns Off
(regardless of the state of the
Shutter Open Request
input), and all DC power is
removed from the RF boards.
Warning
serious
personal
injury
The use of the
Quick Start Plug
bypasses the laser’s safety interlock
function, potentially exposing personnel in the area to
invisible
infrared laser radiation.
The
Quick Start Plug
is intended only for initial testing and trouble-
shooting by qualified personnel. In normal operation, the laser’s
Remote Interlock
input should be connected to the machine’s safety
interlock circuitry.
