vi30/40 Dual Cooled QSG Version 2.1
Firestar™ vi30/40 Dual Cooled Laser Quick Start Guide
Before your OEM vi30/40 laser is put into service for the first time, its functionality
should be verified.
Proceed to the next section or the following procedure if you are not utilizing the UC-
2000 controller to verify the laser system is operating at optimum performance.
Important
Note:
Controlling your laser without a UC-2000 controller:
Caution
Possible
Equipment
Damage
Do not reverse polarity when connecting DC power cables to your DC power
source.
Reversed DC polarity will damage the lasers internal RF and control board
circuitry. Carefully follow the directions below to ensure that DC cable leads are
properly connected to the correct DC output terminals.
Turn off DC power before installing or removing any plug or cable
from the DB-9
I/O connector.
Ensure that user connections are made to the appropriate pins and
that the appropriate signal levels are applied. Failure to do so may damage the
laser.
Vi-Series lasers MUST be provided with a pre-ionizing “tickle” signal
during
standby or laser “low” periods. This signal is automatically provided by SYNRAD
UC-2000 Universal Laser Controller.
A tickle signal keeps the plasma ionized during laser ‘low’
periods and facili-
tates plasma breakdown and pulse-to-pulse fidelity. Damage to or malfunction of
the laser may occur if this, or equivalent drive signals are not provided.
If the laser has been
“OFF” or the tickle has not been applied for any length
of time
apply the tickle signal for at least two seconds before applying any PWM
command signal.
Warning!
Serious Personal
Injury
Always, use lockout/tagout for safety. Always wear safety goggles. Always
use shielded cable when connecting your PWM Command signal source to
PWM Positive/PWM Negative inputs.
In electrically-noisy environments, long lengths of unshielded wire act like
an antenna and may generate enough voltage to trigger uncommanded
lasing.
