SYNRAD FH Series Flyer Operator’s Manual Version 3.4
Initial start-up
Danger
serious
personal
injury
This product emits invisible infrared laser radiation at the 10.6 µm
CO
2
wavelength. Since direct or diuse laser radiation can inict
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. CO
2
lasers emit an invisible beam that is capable of seri-
ously burning human tissue.
Always be aware of the beam’s path and always use a beam block
while testing.
Caution
possible
equipment
damage
Do not attach or remove the DC Power cable while DC power to the
FH Flyer head is energized. This “hot-plug” action causes arcing that
will damage the connector pins and may damage Flyer circuitry.
Always switch AC power to the +30 VDC supply to energize or de-
energize FH Flyer.
4
Ensure that all personnel in the area are wearing the appropriate protective eyewear and then apply
power to Flyer and the laser.
FH Flyer’s operating system requires approximately 25–30 seconds to boot up. During this time, the
Status lamp blinks green at a slow (2 Hz) rate. Flyer is operational when the Status LED illuminates
solid green. Once Flyer is booted up and the optical scanners are activated, you may hear a high-
frequency hiss from the head. This hiss is a normal result of sampling noise that is inherent in the
DSP-based servo loop.
5
If your laser is equipped with a Keyswitch, turn it “On” (clockwise). The laser’s green PWR indicator
(Series 48 laser) or yellow Ready indicator (Evolution
™
or Firestar
®
laser) illuminates and after a ve-
second delay the laser is ready to re.
Note: During standby operation (PWR or Ready indicator on, but no Command signal applied), 5 kHz
“tickle” pulses sent from Flyer to the laser pre-ionize the gas to just below the lase threshold.
These pulses allow the laser to respond almost instantaneously to Command signals from the
marking head as the beam is switched on and o during marking.
6
If you have a 10 W (FLMK-1A) or 25 W (FLMK-2A) fan-cooled marker, there is an adjustable
rheostat inside the fan shroud. Increase cooling fan speed when operating at higher duty cycles or in
locations with high ambient air temperatures.
Caution
possible
equipment
damage
FH Flyer’s operating system requires approximately 25–30 seconds to
boot up. Repeatedly cycling power during the boot up sequence may
cause corruption of Flyer’s ash memory and operating system.
