Introduction
The Introduction section includes subsections:
■Firestar nomenclature
■Model numbers
The Firestar®v30 laser is designed to provide OEMs a compact, cost-eective 30 W laser package. Al-
though the OEM v30 is part of the Firestar family of lasers, its user interface diers signicantly from the
standard Firestar interface design. With the exception of the optoisolated PWM input, PWM Positive, all
OEM v30 input and output signals operate at 5V logic levels to ensure compatibility and ease of installa-
tion when retrotting the Firestar v30 into existing 30 W laser systems. The OEM v30 control board also
diers from other Firestar v-Series models in that it does not incorporate a built-in tickle generator—users
should provide a 5 kHz, 1 µs tickle pulse between applied PWM signals.
Important Note: Firestar OEM v30SxG models do not include a ve-second delay function. This
means a tickle signal can be applied immediately after the Laser Enable input is
activated, eectively eliminating the delay on laser power-up or interlock activa-
tion. See Controlling laser power in the Technical Reference chapter for tickle signal
specications and recommended duration prior to lasing.
As with other laser safety requirements, the OEM or system integrator is solely
responsible for designing the system to incorporate a ve-second delay and any other
controls required by relevant laser safety standards for Class 4 laser devices.
Note: Although the OEM v30 is part of the Firestar family of lasers, its user interface diers signicantly
from the standard Firestar interface design. See the Interface connections section in theTechnical
Reference chapter for details.
The OEM v30 laser is available in either air-cooled (SAG) fan-cooled (SFG), or water-cooled (SWG)
congurations
The Firestar OEM v30 laser is an OEM product intended for incorporation as a component in a laser pro-
cessing system and as such does not comply with 21 CFR, Subchapter J or EN 60825-1 without additional
safeguards.
Firestar nomenclature
Firestar lasers are divided into two distinct functional categories: Keyswitch and OEM models. OEM lasers,
like the OEM v30, do not incorporate keyswitch or shutter functions required by CDRH and EN 60825-1
regulations because they are designed as components for integration into larger processing systems by the
Original Equipment Manufacturer (OEM) or System Integrator who bears full responsibility for meeting
the appropriate laser safety requirements for systems incorporating Class 4 lasers.
Model numbers
The last three characters in the Firestar model number serve to designate the functional category, cool-
ing method, and model version. The functional category is indicated by either a“K” for Keyswitch or “S”
(Switch-less) for OEM models. The next letter indicates the cooling method: “W” for water-cooled units,
“F”for fan-cooled units, and“A”for air-cooled lasers (where the customer must provide the proper cooling
via fans or blowers). The last letter in the model number indicates the current model version beginning
with “B”. For example, the model number FSV30SAG designates the Firestar v30 laser as an OEM, air-
cooled,“G”version unit.

Unpacking
The Unpacking section includes subsections:
■Incoming inspection
■Packaging guidelines
Incoming inspection
Upon arrival, inspect all shipping containers for signs of damage. If you discover shipping damage,
document the damage (photographically if possible), then immediately notify the shipping carrier and
SYNRAD, Inc.
The shipping carrier is responsible for any damage occurring during transportation from SYNRAD, Inc. to
your receiving dock.
Packaging guidelines
■To prevent equipment damage or loss of smaller components, use care when removing packaging
materials.
■After unpacking, review the Inventory section and verify that all components are on hand.
■Save all shipping containers and packaging materials, including covers and plugs. Use these special-
ized packing materials when shipping the laser to another location.
■When packing a laser for shipment, be sure to remove all accessory items not originally attached to
the laser including beam delivery components, connectors, etc.
■Refer to the Firestar v30 packaging instructions drawings in theTechnical Reference chapter for details
on packaging the laser using SYNRAD-supplied shipping materials.
■When shipping water-cooled lasers, remember to drain all cooling water from the laser and then cap
open ttings to prevent debris from entering the coolant path.

Caution
possible
equipment
damage
SYNRAD does not recommend mounting lasers in a vertical “head-
down” or “tail-down” orientation. If you must mount your laser in
this manner, please contact the factory for limitations as a vertical
orientation increases the risk of damage to the laser’s output optic.
Mounting
The OEM v30 base plate is designed so the laser is easily mounted using three 1/4–20 UNC or M6 × 1 ISO
fasteners.Three ball bearing“feet”pressed into the base plate eliminate any possible distortion of the laser
tube caused by variations in the atness of the mounting surface. Refer to OEM v30 package outline draw-
ings in the Technical Reference chapter for mounting locations and dimensions.
Important Note: To prevent possible distortion of the tube, you must fasten the v30 base plate di-
rectly to your mounting surface.
To fasten the OEM v30 laser to your mounting surface, perform the following steps:
1 Refer to the appropriate v30 outline & mounting drawing and drill three holes into your mounting
surface that correspond to either the UNC or metric hole pattern.
2 Place the v30 laser on the mounting surface so that the threaded holes in the base plate line up with
the holes in your mounting surface as shown in Figure 1-2.
Figure 1-2 OEM v30 mounting locations (1/4–20 fastener locations shown)
Note: Mounting bolts must not extend further than 6.0 mm (0.24") into the v30 base plate.
3 Insert three M6 × 1 ISO or 1/4–20 UNC capscrews through the mounting surface into the threaded
holes of the v30 base plate. Turn the screws by hand until the threads engage.
4 Evenly tighten all three capscrews to a maximum torque of 6.1 N m (54 in lb).

Connecting
The Connecting section includes subsections:
■Water-cooled connections
■Air-cooled connections
■Electrical connections
■Control connections
Note: If your OEM v30 laser is fan-cooled (an SFG model), then skip ahead to the Electrical connections
section. For air-cooled (SAG) lasers, go to the Air-cooled connections section.
Water-cooled connections
Cooling tting adaptors
If your integrated laser application uses metric cooling tubing, you should install tubing adaptors to
convert the laser’s WATER IN and WATER OUT ttings from 1/2-inch tubing to 12-mm metric tubing.
These tubing adaptors are available from many tubing and tting manufacturers.
Guidelines for cutting and installing tubing
■Cut tubing lengths generously to allow for trimming.
■Cut tubing squarely; diagonal cuts may not seal properly. Carefully trim any burrs if the cut is “ragged”.
■Avoid excessive stress on ttings; create gentle bends when routing tubing close to connectors. Exces-
sive stress from sharp bends will compromise the sealing properties of the tting.
■Never allow the tubing to kink, since kinking severely restricts coolant ow.
■Push tubing completely into the tting, then pull the tubing to verify that it is locked into place.
■If tubing must be disconnected from a tting, rst push and hold the tubing slightly into the tting.
Next push the release collet evenly towards the tting, and then pull the tubing free.
■After disconnecting tubing from a tting, trim 12.7 mm (0.5”) from its end before reconnecting. Trim-
ming the end of the tubing before reconnecting the tting provides an undisturbed sealing surface.
Chiller preparation guidelines
■You must provide ttings to adapt the laser’s 1/2-inch O.D. polyethylene cooling tubing to your
chiller’s Inlet and Outlet ports. These ttings can be“quick disconnect” or compression type ttings.
■Because Firestar’s cooling tubing is specied in inch sizes, do not use metric tubing ttings unless you
have installed the appropriate inch-to-metric tubing adaptors. The use of metric ttings on inch size
tubing will lead to coolant leaks or may allow the pressurized tubing to blow-o the tting.

Coolants
SYNRAD recommends that the laser’s cooling uid contain at least 90% distilled water by volume. In
closed-loop systems, use a corrosion inhibitor/algaecide such as Optishield®Plus or equivalent as required.
Avoid glycol-based additives because they reduce the coolant’s heat capacity and high concentrations
may aect power stability. For SYNRAD lasers, the minimum coolant setpoint is 18 °C (64 °F) so glycol
is not necessary unless the chiller is subjected to freezing temperatures. If tap water is used, chloride levels
should not exceed a concentration of 25 parts per million (PPM). Install a lter on the chiller’s return line
and inspect frequently. Firestar OEM v30 lasers incorporate the following wetted materials in the coolant
path—nickel-plated brass, copper, acetal, PBT, polyethylene, stainless steel, and Viton®.
Note: DO NOT use de-ionized (DI) water as a coolant. DI water is unusually corrosive and is not rec-
ommended for mixed material cooling systems.
Setting coolant temperature
Choosing the correct coolant temperature is important to the proper operation and longevity of your laser.
When coolant temperature is lower than the dew point (the temperature at which moisture condenses out
of the surrounding air), condensation forms inside the laser housing leading to failure of laser electronics as
well as damage to optical surfaces.
The greatest risk of condensation damage occurs when the laser is in a high heat/high humidity environ-
ment and the chiller’s coolant temperature is colder than the dew point of the surrounding air or when the
system is shut down, but coolant continues to ow through the laser for extended periods of time.
The chiller’s temperature setpoint must always be set above the dew point temperature. In cases where this
is not possible within the specied coolant temperature range of 18 °C to 22 °C (64 °F to 72 °F), then the
following steps MUST be taken to reduce the risk of condensation damage.
■ Air-condition the room or the enclosure containing the laser.
■ Install a dehumidier to reduce the humidity of the enclosure containing the laser.
■ Stop coolant ow when the laser is shut down.
■ Increase coolant ow by an additional 3.8 lpm (1.0 GPM). Do not exceed a coolant pressure of 414
kPa (60 PSI).
Table 1-2 on the following page provides dew point temperatures for a range of air temperature and rela-
tive humidity values. Remember that the laser’s coolant temperature must be set above the dew point
temperatures shown in the chart; however, for best results and performance, do not exceed a coolant
temperature of 22 °C (72 °F).

To use Table 1-2, look down the Air Temp column and locate an air temperature in Fahrenheit or Cel-
sius (°C values are shown in parentheses) that corresponds to the air temperature in the area where your
laser is operating. Follow this row across until you reach a column matching the relative humidity in your
location. The value at the intersection of the Air Temp and Relative Humidity columns is the Dew Point
Temperature in °F (or °C). The chiller’s temperature setpoint must be set above the dew point tempera-
ture. For example, if the air temperature is 85 °F (29 °C) and the relative humidity is 60%, then the dew
point temperature is 70 °F (21 °C). Adjust the chiller’s temperature setpoint to 72 °F (22 °C) to prevent
condensation from forming inside the laser.
Caution
possible
equipment
damage
Operating the laser at coolant temperatures above 22 °C (72 °F)
may result in decreased laser performance and/or premature failure of
electronic components.
