Synrad Firestar ti-Series operator’s manual
Initial start-up
3
Rotate the Keyswitch (if equipped) to the ON position. Verify that the RDY (Ready) indicator on the
laser’s rear panel is illuminated.
Note: Each time an OEM laser is powered up or a keyswitch version is cycled OFF/ON, a five-second
delay occurs between the time that RDY and/or SHT indicators illuminate and Firestar is permit-
ted to lase.
Warning
serious
personal
injury
Because of phase differences, external tickle pulses may combine
with the internally-generated tickle signal causing the LASE LED to
flicker during the transition from tickle to lasing. Laser output may
occur if the LASE LED flickers.
Caution
possible
equipment
damage
Do not flow coolant through the laser for an extended period of time
when the laser is shutdown. This causes condensation to form inside
the laser that may result in catastrophic damage to internal optics
and electronic circuits.
Note: For remote keyswitch operation (keyswitch versions), you can set the Keyswitch to the ON posi-
tion and use the Remote Reset/Start Request input (on the User I/O connector) as a remote
keyswitch similar to other SYNRAD laser models.
4
Press the UC-2000’s Lase On/Off button. The Lase indicator on the UC-2000 should illuminate.
5
Use the UC-2000’s PWM Adj Knob to slowly increase power. The laser’s LASE indicator illuminates
red when PWM signal pulses are long enough to produce laser output (typically 3–6 µs at 5 kHz).
The spot where the beam hits the beam block increases in brightness, to indicate increased power
output.
6
Press the UC-2000’s Lase On/Off button to stop lasing. LASE indicators on the UC-2000 and the
laser should turn off.
7
Place Firestar’s Shutter Switch (if equipped) in the Closed position.
8
On water-cooled lasers, shut off the chiller or otherwise stop coolant flow through the laser.
If your Firestar ti-Series laser fails to lase, refer to Troubleshooting in the Maintenance/Troubleshooting
chapter for troubleshooting information.
