injury

This Class 4 laser product emits invisible infrared laser radiation in the 9.3–10.6 µm
CO2 wavelength band depending on model.

Do not allow laser radiation to enter the eye by viewing direct or reflected laser energy.
CO2 laser radiation can be reflected from metallic objects even though the surface is
darkened. Direct or diffuse laser radiation can inflict severe corneal injuries leading to
permanent eye damage or blindness. All personnel must wear eye protection suit­able for 9.3–10.6 µm CO2 radiation when in the same area as an exposed laser beam.
Eyewear protects against scattered energy but is not intended to protect against direct
viewing of the beam—never look directly into the laser output aperture or view scat­tered laser reflections from metallic surfaces.

Enclose the beam path whenever possible. Exposure to direct or diffuse CO2 laser radia­tion can seriously burn human or animal tissue, which may cause permanent damage.

Danger

This product is not intended for use in explosive, or potentially explosive, atmospheres.

U.S. customers should refer to and follow the laser safety precautions described in the
American National Standards Institute (ANSI) Z136.1-2007 document, Safe Use of
Lasers. Procedures listed in this Standard include the appointment of a Laser Safety Of­ficer (LSO), operation of the product in an area of limited access by trained personnel,
servicing of equipment only by trained and authorized personnel, and posting of signs
warning of the potential hazards.

European customers should appoint a Laser Safety Officer (LSO) who should refer to
and follow the precautions described in EN 60825-1, 2007—Safety of Laser Products.

Materials processing can generate air contaminants such as vapors, fumes, and/or parti­cles that may be noxious, toxic, or even fatal. Material Safety Data Sheets (MSDS) for
materials being processed should be thoroughly evaluated and the adequacy of provi­sions for fume extraction, filtering, and venting should be carefully considered. Review
the following references for further information on exposure criteria:

ANSI Z136.1-2007, Safe Use of Lasers, section 7.3.

U.S. Government’s Code of Federal Regulations: 29 CFR 1910, Subpart Z.

Use of controls or adjustments or performance of procedures other than those specified
herein may result in hazardous radiation exposure.

The use of aerosol dusters containing difloroethane causes “blooming”, a condition that
significantly expands and scatters the laser beam. This beam expansion can effect mode
quality and/or cause laser energy to extend beyond the confines of optical elements in
the system, possibly damaging acrylic safety shielding. Do not use air dusters containing
difloroethane in any area adjacent to CO2 laser systems because difloroethane persists
for long time periods over wide areas.

A risk of exposure to toxic elements, like zinc selenide, may result when certain optical
or beam delivery components are damaged. In the event of damage to laser, marking
head, or beam delivery optics, contact SYNRAD, Inc. or the optics manufacturer for
handling instructions.

Synrad Firestar OEM v30 reference guide

Hazard information (cont.)

Firestar® v30 lasers should be installed and operated in manufacturing or laboratory facilities by trained personnel only. Due
to the considerable risks and hazards associated with the installation and operational use of any equipment incorporating a
laser, the operator must follow product warning labels and instructions to the user regarding laser safety.

To prevent exposure to direct or scattered laser radiation, follow all safety precautions specified throughout this manual and
exercise safe operating practices per ANSI Z136.1-2007 at all times when actively lasing.

Always wear safety glasses or protective goggles with side shields to reduce the risk of damage to the eyes when operating the
laser.

A CO2 laser is an intense heat source and will ignite most non-metallic materials under the proper conditions. Never oper­ate the laser in the presence of flammable or explosive materials, gases, liquids, or vapors.

The use of controls or adjustments or performance of procedures other than those specified herein may result in exposure to
hazardous invisible laser radiation, damage to, or malfunction of the laser. Severe burns will result from exposure to the laser
beam.

Safe operation of the laser requires the use of an external beam block to safely block the beam from traveling beyond the
desired work area. Do not place your body or any combustible object in the path of the laser beam. Use a water-cooled beam
dump or power meter, or similar non-scattering, noncombustible material as the beam block. Never use organic material or
metals as the beam blocker; organic materials, in general, are apt to combust or melt and metals act as specular reflectors
which may create a serious hazard outside the immediate work area.

Other hazards

The following hazards would be typical for this product family when incorporated for intended use: (A) risk of injury when
lifting or moving the unit; (B) risk of exposure to hazardous laser energy through unauthorized removal of access panels,
doors, or protective barriers; (C) risk of exposure to hazardous laser energy and injury due to failure of personnel to use
proper eye protection and/or failure to adhere to applicable laser safety procedures; (D) risk of exposure to hazardous or le­thal voltages through unauthorized removal of covers, doors, or access panels; (E) generation of hazardous air contaminants
that may be noxious, toxic, or even fatal.

Disposal

This product contains components that are considered hazardous industrial waste. If a situation occurs where the laser is
rendered non-functional and cannot be repaired, it may be returned to SYNRAD, Inc. who, for a fee, will ensure adequate
disassembly, recycling, and/or disposal of the product.

Additional laser safety information

The SYNRAD web site (http://www.synrad.com/LaserFacts/lasersafety.html) contains an online laser safety handbook that
provides information on (1) Laser Safety Standards for OEM’s/System Integrators including product classification, prod­uct housing, product features, and other CDRH requirements; (2) Laser Safety Standards for End Users including Class 1
installations, Class 4 installations, laser hazards, ANSI Standard, U.S. State requirements, and OSHA; (3) References and

Agency compliance

SYNRAD lasers are designed, tested, and certified to comply with certain United States (U.S.) and European Union (EU)
regulations. These regulations impose product performance requirements related to electromagnetic compatibility (EMC)
and product safety characteristics for industrial, scientific, and medical (ISM) equipment. The specific provisions to which
systems containing Firestar OEM v30 lasers must comply are identified and described in the following paragraphs.

In the U.S., laser safety requirements are governed by the Center for Devices and Radiological Health (CDRH) under the
auspices of the U.S. Food and Drug Administration (FDA) while radiated emission standards fall under the jurisdiction of
the U.S. Federal Communications Commission (FCC). Outside the U.S., laser safety and emissions are governed by Euro­pean Union (EU) Directives and Standards.

In the matter of CE-compliant laser products, SYNRAD, Inc. assumes no responsibility for the compliance of the system
into which the product is integrated, other than to supply and/or recommend laser components that are CE marked for com­pliance with applicable European Union Directives.

Because OEM laser products are intended for incorporation as components in a laser processing system, they do not meet
all of the Standards for complete laser processing systems as specified by 21 CFR, Part 1040 or EN 60825-1. SYNRAD, Inc.
assumes no responsibility for the compliance of the system into which OEM laser products are integrated.

Center for Devices and Radiological Health (CDRH) requirements

Firestar v30 OEM lasers are OEM products intended for incorporation as components in laser processing systems. As sup­plied by SYNRAD, these lasers do not meet the requirements of 21 CFR, Subchapter J without additional safeguards. In the
U.S., the Buyer of these OEM laser components is solely responsible for the assurance that the laser processing system sold
to an end user complies with all laser safety requirements before the actual sale of the system. Under CDRH regulations,
the Buyer must submit a report to the CDRH prior to shipping the system. In jurisdictions outside the U.S., it is the sole
responsibility of the Buyer of these OEM components to ensure that they meet all applicable local laser safety requirements.
In cases where the Buyer is also the end-user of the OEM laser product, the Buyer/end-user must integrate the laser so that it
complies with all applicable laser safety standards as set forth above.

To aid in the development of integrated v30 systems see Table 1, Class 4 safety features. The table indicates which features
are available on OEM v30 lasers, the type and description of the feature, and if the feature is required by CDRH regulations.

Federal Communications Commission (FCC) requirements

The United States Communication Act of 1934 vested the Federal Communications Commission (FCC) with the author­ity to regulate equipment that emits electromagnetic radiation in the radio frequency spectrum. The purpose of the Com­munication Act was to prevent harmful electromagnetic interference (EMI) from affecting authorized radio communication
services. The FCC regulations that govern industrial, scientific, and medical (ISM) equipment are fully described in 47 CFR,
Part 18, Subpart C.

SYNRAD’s Firestar OEM v30E lasers have been tested and found to comply by demonstrating performance characteristics
that have met or exceeded the requirements of 47 CFR, Part 18, Radiated and Conducted Emissions.

FCC information to the user

NOTE: The following FCC information to the user is provided to comply with the requirements of 47 CFR, Part 18, Section

213.

Interference Potential

In our testing, SYNRAD, Inc. has not discovered any significant electrical interference traceable to Firestar
OEM v30 lasers.

Agency compliance (cont.)

System Maintenance

Ensure that all exterior covers are properly fastened in position.

Measures to Correct Interference

If you suspect that your Firestar OEM v30 laser interferes with other equipment, take the following steps to
minimize this interference:

1

Use shielded cables to and from the equipment that is experiencing interference problems.

2

Ensure that the OEM v30 laser is properly grounded to the same electrical potential as the equipment or

system it is connected to.

FCC caution to the user

The Federal Communications Commission warns the user that changes or modifications of the unit not expressly approved
by the party responsible for compliance could void the user’s authority to operate the equipment.

European Union (EU) requirements

RoHS compliance

SYNRAD Firestar OEM v30 lasers meet the requirements of the European Parliament and Council Directive 2011/65/EU
on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment that establishes maxi­mum concentration values for certain hazardous substances in electrical and electronic equipment.

Laser safety standards

Under the Low Voltage Directive, 2006/95/EC, the European Norm document 60825-1 was developed to protect persons
from laser radiation by imposing requirements upon manufacturers of laser products to provide an indication of laser radia­tion; to classify laser products according to the degree of hazard; to require both user and manufacturer to establish proce­dures so that proper precautions are adopted; to ensure adequate warning of the hazards associated with accessible radiation
through signs, labels, and instructions; to improve control of laser radiation through protective features; and to provide safe
usage of laser products by specifying user control measures.

SYNRAD’s OEM v30 lasers are OEM products intended for incorporation as components in laser processing systems. As
supplied by SYNRAD, these lasers do not meet the requirements of EN 60825-1 without additional safeguards. European
Union Directives state that “OEM laser products which are sold to other manufacturers for use as components of any system
for subsequent sale are not subject to this Standard, since the final product will itself be subject to the Standard.” This means
that Buyers of OEM laser components are solely responsible for the assurance that the laser processing system sold to an
end-user complies with all laser safety requirements before the actual sale of the system. Note that when an OEM laser com­ponent is incorporated into another device or system, the entire machinery installation may be required to conform to EN
60825-1; EN 60204-1, Safety of Machinery; the Machinery Directive EN 2006/42/EC; and/or any other applicable Standards.
In cases where the Buyer is also the end-user of the OEM laser product, the Buyer/end-user must integrate the laser so that it
complies with all applicable laser safety standards as set forth above.

To aid in the development of integrated v30 systems see Table 1, Class 4 safety features. The table indicates which features
are available on OEM v30 lasers, the type and description of the feature, and if the feature is required by European Union
regulations.

Introduction

Although the OEM v30 laser is part of the Firestar v-Series family, its user interface differs significantly from the standard
v-Series interface design. With the exception of the optoisolated PWM input (PWM Positive), all OEM v30 inputs and out­puts operate at 5V logic levels to ensure compatibility and ease of installation when retrofitting the Firestar v30 into existing
laser systems. The OEM v30 control board also differs from other Firestar v-Series models in that it does not incorporate a
built-in tickle generator; users must provide a 5 kHz, 1 µs tickle pulse between applied PWM signals.

The OEM v30 laser is available in air-cooled (SAE), fan-cooled (SFE), or water-cooled (SWE) configurations.

The Firestar OEM v30 laser is an OEM product intended for incorporation as a component in a laser processing system and
as such does not comply with 21 CFR, Subchapter J or EN 60825-1 without additional safeguards.

Mounting

The OEM v30 base plate is designed so that the laser can be easily mounted using only 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 flatness of the mounting surface. See OEM v30 outline and mounting drawings later in this document for
mounting dimensions.

Note: To maintain proper airflow, the OEM v30 must have at least 57.2 mm (2.25") of unobstructed clearance between

the outside edge of the cooling fans and any enclosure or surface.

To fasten the OEM v30 to your mounting surface, perform the following steps:

1

Refer to the v30 outline and mounting diagram and drill three holes into your mounting surface that correspond to

either the UNC or metric base plate bolt pattern.

2

Place the v30 on the mounting surface so that the threaded holes on the base plate line up with the holes in your

mounting surface.

3

Insert three 1/4–20 UNC or M6 × 1 capscrews through the mounting surface into the corresponding 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 value of 6.1 N m (54 in lb).

Cooling connections

If your OEM v30 laser is fan-cooled (an SFE model), then skip ahead to the Electrical connections section. For air-cooled
lasers, go to the Air-cooled connections section.

Water-cooled connections

Cooling fitting 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 fittings from 1/2-inch tubing to 12-mm metric tubing. These tubing adaptors are available from

many tubing and fitting 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 fittings; create gentle bends when routing tubing close to connectors. Excessive stress from

sharp bends will compromise the sealing properties of the fitting.

■Never allow the tubing to kink, since kinking severely restricts coolant flow.

■Push tubing completely into the fitting, then pull the tubing to verify that it is locked into place.

■If tubing must be disconnected from a fitting, first push and hold the tubing slightly into the fitting. Next push the white

fitting ring evenly towards the fitting, and then pull the tubing free.

■After disconnecting tubing from a fitting, trim 12.7 mm (0.5") from its end before reconnecting. Trimming the end of

the tubing before reconnecting the fitting provides an undisturbed sealing surface.

Synrad Firestar OEM v30 reference guide

Cooling connections (cont.)

Chiller preparation guidelines

■You must provide fittings to adapt the laser’s 1/2-inch O.D. polyethylene cooling tubing to your chiller’s Inlet and Out-

let ports. These fittings can be “quick disconnect” or compression type fittings.

■Because Firestar’s cooling tubing is specified in inch sizes, do not use metric tubing fittings unless you have installed the

appropriate inch-to-metric tubing adaptors. The use of metric fittings on inch size tubing will lead to coolant leaks or
may allow the pressurized tubing to blow-off the fitting.

Coolants

SYNRAD recommends that the laser’s cooling fluid 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 affect 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 filter 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 recommended 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 environment 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 flow 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 specified 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 dehumidifier to reduce the humidity of the enclosure containing the laser.

■ Stop coolant flow when the laser is shut down.

■ Increase coolant flow by an additional 3.8 lpm (1.0 GPM). Do not exceed a coolant pressure of 414 kPa (60 PSI).

Table 4 on the following page provides dew point temperatures for a range of air temperature and relative 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 4, look down the Air Temp column and locate an air temperature in Fahrenheit or Celsius (°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 Rela-
tive Humidity columns is the Dew Point Temperature in °F (or °C). The chiller’s temperature setpoint must be set above the
dew point temperature. 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.

Cooling connections (cont.)

Air-cooled connections (SA models)

Air-cooled v30 (SA) lasers are shipped without cooling fans so customers must provide some type of air cooling to prevent
overheating and keep laser/RF heatsink temperatures below 45 °C (113 °F). We recommend using two cooling fans rated
for at least 4.0 m3/min (140 CFM) at a static air pressure of 13.2 mm H2O (0.52 in H2O). Mount them as shown in Figure

4. Cooling fans should have a diameter of approximately 120 × 120 mm (4.7 × 4.7") and have at least 57.2 mm (2.25" ) of
unobstructed clearance between the outside edge of the fan housing and any mounting surface or enclosure.

OEM v30 SA lasers do not provide a voltage output sufficient to power cooling fans; users must provide an external power
source appropriate for the selected cooling fans. Because of the heat generated by internal RF circuitry, establishing sig­nificant airflow evenly over the entire surface of the combined laser/RF chassis is vitally important to the performance and
longevity of the laser.

Fans should be mounted so that they are centered both

horizontally and vertically on each side of the OEM v30 laser.

Figure 4 Recommended v30 cooling fan locations

SYNRAD recommends side-mounted cooling fans for OEM v30 lasers, but rear-mounted, single-fan cooling design is possi­ble. Figure 5 illustrates the rear-cooling concept. Review the guidelines listed below to ensure that your integration provides
enough air flow to prevent damage to the laser. The fan must supply at least 8.5 m3/min (300 CFM) to prevent overheating.
A rear-cooled laser may experience some performance loss when compared to a typical side-mounted cooling configuration.

Guidelines for rear cooling

■ Design the cooling shroud so that it encloses the full length of both the laser and the cooling fan.

■ Fit the shroud snugly against the laser’s cooling fins so that air is ducted between the fins and not around them.

■ For proper heat removal, open the shroud at the front to direct air flow through the laser.

■ Use a cooling fan rated for a least 8.5 m

position it approximately 150 mm (6.0") from the rear of the laser.

DC power supply

The air-cooled v30 (SA) laser requires a DC power supply capable of providing 30 VDC at 15 A (24 A peak for a minimum
of 0.5 ms) while fan-cooled (SFE) lasers require 30 VDC at 16 A (24 A peak for a minimum of 0.5 ms). We recommend the
SYNRAD PS-2 a 30 V, 750 W DC power supply (shown in Figure 6). AC input requirements for the PS-2 power supply are
90–264 VAC (auto-ranging); single phase (1Ø); 10 A maximum; 47–440 Hz. To connect the PS-2 power supply, refer to
Figure 6 and perform the following steps:

Note: The negative (–) side of the DC input to the laser is internally connected so that the laser chassis serves as DC

power ground. You should isolate the laser’s DC power supply so that the only grounded connection is at the laser.
Alternatively, you can mount the laser chassis on an insulating pad or film in order to electrically isolate the laser
when other equipment is grounded to the laser’s DC power supply.

5

Connect the hot wire from your AC voltage source, typically black, to the “L” (AC Line) terminal.

6

Connect the ground (earth) wire from the AC source, typically green, to the terminal labeled with the ground symbol.

Note: Because AC input connections and requirements vary from country to country, customers must provide the appro-

priately sized AC power cable or wiring.

Control connections

Complete all control connections to the OEM v30 laser through the Interface A (DB-9) or Interface B (RJ45) connectors on
the v30’s rear panel. The interface connector receives tickle pulse and PWM Command signals and also serves as the con­nection point for auxiliary signals between the laser and any parts handling, automation, or monitoring equipment. Refer to
the Technical Reference section for specific details about the OEM v30 user interface.

The OEM v30 control board differs from other Firestar v-Series models in that it does not incorporate a built-in tickle gen­erator. If you are not using a SYNRAD UC-2000 Universal Laser Controller to operate the laser, you must provide
a 5 kHz, 1 µs tickle pulse between applied PWM signals.

Refer to the Firestar v40 Operator’s Manual and see Controlling laser power in the Technical Reference chapter for tickle signal
descriptions. A PDF version is available from our web site at: http://www.synrad.com/Products/manuals.htm.

Danger

serious

personal

On Firestar OEM v30 lasers, DC voltage faults are not latched. Clearing a DC voltage
fault (under- or over-voltage) will restore normal operation and lasing is possible after
the five-second delay provided that the Laser Enable input signal is high. Because
exposure to 9.3–10.6 µm CO2 laser radiation can inflict severe corneal injuries and seri­ously burn human tissue, the OEM or System Integrator must ensure that appropriate
safeguards are in place to prevent unintended lasing.

This Class 4 laser product emits invisible infrared laser radiation in the 9.3–10.6 µm
CO2 wavelength band depending on model. Because direct or diffuse laser radiation
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.

injury

Always be aware of the beam’s path and always use a beam block while testing.

Note: After applying 30 VDC, but before operating the laser, you must provide a Laser Enable signal to the appropriate

Interface A (DB-9) or Interface B (RJ45) connector.

1

If you have not already done so, remove the red self-adhesive aperture seal from the front of the laser.

2

Ensure that all personnel in the area are wearing protective eyewear.

3

Place a beam block 61 cm (24 in) from the laser aperture to prevent the beam from traveling beyond the work area.

Note: If you are using a UC-2000 to control the v30 laser, refer to the UC-2000 Laser Controller Operator’s Manual for

setup and operation instructions before continuing.

If you are not using a UC-2000 to control the laser, you must provide tickle and PWM Command signals to control

power output. Refer to the Firestar v40 Operator’s Manual and see Controlling laser power in the Technical Reference
chapter for tickle and PWM Command signal descriptions. A PDF version is available from our web site at http://
www.synrad.com/Products/manuals.htm.

Operation (cont.)

5

Turn on the +30 VDC power supply. The PWR LED should illuminate green.

6

If the laser has a Diode Pointer installed, remove its aperture dust cover.

7

Apply a Laser Enable signal to the appropriate Interface Connector. The yellow RDY lamp turns on to indicate that,

after a five-second delay, lasing is enabled when a PWM Command signal is received.

8

Press the UC-2000’s Lase On/Off button. The Lase indicator on the UC-2000 should illuminate.

9

Use the PWM Adj Knob on the UC-2000 Controller to slowly increase power. The v30 LASE LED illuminates red

when PWM Command pulses are long enough to produce laser output. The spot where the beam hits the beam block
should increase in brightness, indicating an increasing power output.

If you are not using a UC-2000 to control the laser, apply tickle pulses (a +5 VDC, 5 kHz square wave of 1 µs dura­tion) between PWM Positive (Pin 1) and PWM Negative (Pin 6) on the appropriate DB-9 or RJ45 connector. After
five to ten seconds, slowly increase the PWM duty cycle of the square wave. The v30 LASE LED illuminates red when
PWM Command pulses are long enough to produce laser output. The spot where the beam hits the beam block should
increase in brightness, indicating an increasing power output.

10

Press the UC-2000’s Lase On/Off button to remove the PWM Command signal from the laser. The LASE LED turns

off. If your v30 laser fails to lase, refer to the Troubleshooting section for troubleshooting information.

If you are not using a UC-2000 to control the laser, remove the PWM Command signal from the laser and re-apply
tickle pulses every 200 µs. If your v30 laser fails to lase, refer to the Troubleshooting section.

Technical reference

v30 interface connectors

Two built-in interface options are available for integrating the OEM v30—a DB-9 and an RJ45 8-8 interface connector. The
RJ45 connector (Interface B) is useful when integrating a v30 into existing integrated laser systems previously configured for
an RJ45 interface. Use the DB-9 connector (Interface A) for new Firestar installations. Although both interface connectors
provide the same functionality, the DB-9 connector contains an additional output, Lase Indicator, that activates when the
OEM v30 is actively lasing.

The v30’s PWM input (PWM Positive) is optoisolated, however all other inputs and outputs operate using standard 5V logic
levels (0 V – logic low; 5 V – logic high). Inputs and outputs are ESD protected, but are not optoisolated; all input signals
sent to the laser must be clean or conditioned by the user. Signals for each interface connector, A or B, are described below.

Important Note: Do not connect both Interface A and Interface B connectors at the same time as this will damage the

laser’s control board. Wire only one interface into your control system.

Note: OEM v30 outputs are voltage sources. They can provide only 20 mA typical, 40 mA maximum, to a ground

referenced load. The control board will be damaged if this current maximum is exceeded. For either connector,
Interface A or Interface B, the ground reference (GND) is Pin 8.

Interface A connector (DB-9)

The DB-9 Interface A connector provides a +5 VDC auxiliary output (DC Out), two inputs, and four status outputs as de­scribed in Table 5. Two user inputs, Laser Enable and PWM Positive, enable lasing and provide output power control.

Apply a +5 V signal to the Laser Enable input to enable lasing (after a five-second delay). Connect your PWM Command
signal (+ 5 VDC, 5 kHz nominal) between PWM Positive and PWM Negative inputs to control laser power. There is no inter­nal tickle signal generated by the OEM v30 control board. Users must provide a 5 kHz, 1 µs tickle pulse between applied
PWM Command signals.

22

Synrad Firestar OEM v30 reference guide

Technical reference (cont.)

Note: You must connect a Laser Enable signal to Pin 9 before applying a PWM Command signal to Pin 1, PWM Positive,

The DB-9 Interface A connector provides four 5V logic level outputs to communicate laser status to the control system.
Laser Ready goes high when lasing is possible; the output is low when the laser is not ready. Lase Indicator goes high when the

PWM signal is sufficient to induce laser output; the output is low when no beam is being emitted. DC Voltage Fault goes high
after sensing an under/over voltage condition; the output is low when the DC supply voltage is within limits. Overtemp Fault
goes high when laser temp rises above its upper thermal limit; otherwise, the output is low.

Note: When an over temperature condition occurs, cool the laser below its over temperature threshold and then cycle

DC power to restore normal operation.

8 GND Ground pin for all DB-9 input/output signals except PWM Positive.

9 Laser Enable Logic input. Enables laser when high; disables laser when low. A five-second delay is invoked after
this pin goes high. Laser Enable must be high before PWM Positive can fire the laser.

Note: When switching +5 VDC to the Laser Enable input (DB-9, Pin 9) through a switch or relay contact, we highly

recommend adding a 100 Ohm, 1/4 watt resistor in series between the switching device and the Laser Enable input.

Technical reference (cont.)

Interface B connector (RJ45)

The RJ45 8-8 Interface B connector provides a +15 VDC auxiliary output (DC Out), two inputs, and three status outputs
(Table 6). Two user inputs, Laser Enable and PWM Positive, enable lasing and provide output power control.

Apply a +5 V signal to the Laser Enable input to enable lasing (after a five-second delay). Control power by connecting a
PWM Command signal (+5 VDC, 5 kHz nominal) between PWM Positive and PWM Negative (or GND) inputs. The OEM
v30 does not generate a tickle signal so customers must provide a 5 kHz, 1 µs tickle pulse between applied PWM signals.

Note: You must send a Laser Enable signal to Pin 7 before applying a PWM Command signal. Configure your control

system to provide a Laser Enable signal only after all other safe operating conditions are met.

Caution

possible

equipment

The Interface B (RJ45) Laser Enable input is a direct 5V logic input. Do not send
a voltage signal to the Laser Enable input (Pin 7) until DC power is applied—the
control board will be damaged. Observe all 5V logic specifications and precau­tions when integrating Firestar OEM v30 inputs and outputs into your control
system.

damage

PWM Negative (Pin 6) must be connected to GND (Pin 8) or it must serve as the
return path for the PWM Positive signal.

On the RJ45 connector, three 5V logic level outputs are available to communicate laser status to the control system. Laser
Ok is high when lasing is possible; the output goes low when a fault is detected. Voltage Ok is high when the DC supply
voltage is within limits; low after sensing an under/over voltage condition. Temperature Ok is high when laser temperature is
within limits; low if laser temperature rises above its thermal limit.

Note: When switching +5 VDC to the Laser Enable input (RJ45, Pin 7) through a switch or relay contact, we highly

recommend adding a 100 Ohm, 1/4 watt resistor in series between the switching device and the Laser Enable input.

Table 6 Interface B (RJ45 8-8) pinouts

Pin Name Function

1 PWM Positive Optoisolated input for PWM/tickle signals. Reference to PWM Negative (Pin 6) or GND (Pin 8).

2 DC Out Pin 2 provides a +15 VDC, 250 mA maximum, user output voltage.

3 Laser Ok Logic output high when no faults detected; low if laser fault. The Laser Ok output sources 20 mA
typical, 40 mA maximum.

4 Temperature Ok Logic output high when temperature within limits; low if over temperature condition detected. The
Temperature Ok output sources 20 mA typical, 40 mA maximum.

5 Voltage Ok Logic output high when DC supply voltage within limits; low if DC input is under/over voltage. The
Voltage Ok output sources 20 mA typical, 40 mA maximum.

6 PWM Negative Negative side of optoisolated PWM Command signal. Reference Pin 6 to PWM Positive (Pin 1) or
GND (Pin 8). If this input does not provide a PWM return, it must be connected to GND (Pin 8).
The control board will be damaged if this pin is left unconnected.

7 Laser Enable Logic input. Enables laser control when high; disables laser when low. A five-second delay is invoked
after this pin goes high. Laser Enable must be high before PWM Positive can fire the laser.

8 GND Ground (return) pin for RJ45 input/output signals.

Troubleshooting (cont.)

Error codes

Firestar OEM v30 lasers have the ability to indicate various laser faults by flashing RDY and PWR indicators. For OEM v30
lasers manufactured after October 1, 2011, certain faults are annunciated by the PWR LED blinking an error code, pausing
1/2 second, and then repeating the error code. This sequence continues until the fault is corrected and the laser is reset by
cycling DC power. Table 10 lists error codes, the corresponding fault condition, and describes possible corrective actions.

Table 10 Firestar v30 error codes

LED # of Blinks Fault Condition Corrective Action in Field

RDY Off
PWR 1 blink Under-Voltage fault Verify 30 VDC (measured at laser under load)

RDY Off
PWR 2 blinks Over-Voltage fault Verify 30 VDC (measured at laser under load)

RDY Off
PWR 3 blinks DC Sense fault Remove DC power, wait 30 seconds, and then re-apply power.

RDY Continuous

RDY Continuous
PWR Continuous PWM Sense fault Remove DC power, wait 30 seconds, and then re-apply power.

1 An over temperature fault is indicated if the Overtemp Fault output is high (+5 V). If the Overtemp Fault output is low, then a control board failure

may have occurred.

Laser faults

When a fault occurs, status LEDs and output signals reflect faults as indicated in Table 8, Table 9, or Table 10. Each Symp­tom listed below describes a particular fault and specific causes and solutions are described in the Possible Causes section.

Symptom:

■ The RDY indicator is Off. The PWR LED is green and the LASE LED is Off. On the Interface A (DB-9) connector, all

outputs (Lase Indicator, Laser Ready, DC Voltage Fault, and Overtemp Fault) are Low. On the Interface B (RJ45)
connector, the Laser Ok signal is Low while Voltage Ok and Temperature Ok outputs are High.

Possible Causes:

■ No Laser Enable input signal is present.

A 5V logic level Laser Enable signal must be applied to enable lasing. On the Interface A (DB-9) connector, apply the en­able signal between Pin 9 and Pin 8. On the Interface B (RJ45) connector, apply the enable signal between Pin 7 and Pin 8.

Symptom:

■ The RDY LED is flashing. The PWR LED is green and the LASE LED is Off. On the Interface A (DB-9) connector,

Lase Indicator, Laser Ready, and DC Voltage Fault, outputs are Low, but the Overtemp Fault output is High. On the
Interface B (RJ45) connector, the Voltage Ok signal is High while Laser Ok and Temperature Ok outputs are Low.

Possible Causes:

■ An over temperature fault exists.

30

Synrad Firestar OEM v30 reference guide

Troubleshooting (cont.)

Cool the v30’s temperature to below 40 °C (air-/fan-cooled) or 22 °C (water-cooled) and then cycle DC power to the laser.
For air-/fan-cooled units, verify that cooling fans are free of debris and providing the proper airflow; for water-cooled units,
check that the chiller is maintaining the correct coolant temperature and flow rate.

Symptom:

■ The RDY indicator is flashing. The PWR LED is green and the LASE LED is Off. On the Interface A (DB-9) connector,

all outputs (Lase Indicator, Laser Ready, DC Voltage Fault, and Overtemp Fault) are Low. On the Interface B (RJ45)
connector, the Laser Ok signal is Low while Voltage Ok and Temperature Ok outputs are High.

Possible Causes:

■ A control board failure has occurred.

Contact SYNRAD or a SYNRAD Authorized Distributor.

Warning

serious

personal

injury

On Firestar OEM v30 lasers, DC voltage faults are not latched. Clearing a DC voltage
fault (under- or over-voltage) will restore normal operation and lasing is possible after
the five-second delay provided that the Laser Enable input signal is high. Because
exposure to 9.3–10.6 µm CO2 laser radiation can inflict severe corneal injuries and seri­ously burn human tissue, the OEM or System Integrator must ensure that appropriate
safeguards are in place to prevent unintended lasing.

Symptom:

■ The PWR indicator blinks once, pauses 1/2 second and repeats. Both RDY and LASE LEDs are Off. On the Interface A

(DB-9) connector, Lase Indicator, Laser Ready, and Overtemp Fault outputs are Low, but the DC Voltage Fault out­put is High. On the Interface B (RJ45) connector, the Temperature Ok signal is High while the Laser Ok and Voltage
Ok outputs are Low.

Possible Causes:

■ An under-voltage fault exists.

Check that the DC power supply is supplying +30 VDC under load and that its current capacity is 15 amperes or greater
(air-/water-cooled) or 16 amps or greater (fan-cooled) with a peak current capacity of 24 A for a minimum of 0.5 ms.

■ An under-voltage condition exists (DC power supply is current-limiting) because PWM signals were applied before tube

breakdown occurred.

On a cold start, verify that tickle pulses are being sent to the v30 laser for a period of five to ten seconds before a PWM
signal is applied.

Symptom:

■ The PWR indicator blinks twice, pauses 1/2 second and repeats. Both RDY and LASE LEDs are Off. On the Interface A

(DB-9) connector, Lase Indicator, Laser Ready, and Overtemp Fault outputs are Low, but the DC Voltage Fault out­put is High. On the Interface B (RJ45) connector, the Temperature Ok signal is High while the Laser Ok and Voltage
Ok outputs are Low.

Possible Causes:

■ An over-voltage fault exists.

Check that the DC power supply is supplying +30 VDC under load.

Synrad Firestar OEM v30 reference guide

31

Troubleshooting (cont.)

Symptom:

■ The PWR indicator blinks three times, pauses 1/2 second and repeats. Both RDY and LASE LEDs are Off. On the

Interface A (DB-9) connector, Lase Indicator, Laser Ready, and Overtemp Fault outputs are Low, but the DC Voltage

Fault output is High. On the Interface B (RJ45) connector, the Temperature Ok signal is High while the Laser Ok and
Voltage Ok outputs are Low.

Possible Causes:

■ A DC Sense fault has occurred.

Remove DC power from the laser, wait 30 seconds, and then re-apply DC power. If the fault fails to clear, contact SYNRAD
or a SYNRAD Authorized Distributor.

Symptom:

■ Both PWR and RDY indicators are flashing. The LASE LED is Off. On the Interface A (DB-9) connector, all outputs

(Lase Indicator, Laser Ready, DC Voltage Fault, and Overtemp Fault) are Low. On the Interface B (RJ45) connector,
the Temperature Ok and Voltage Ok outputs are High while the Laser Ok signal is Low.

Possible Causes:

■ A PWM Sense fault has occurred.

Remove DC power from the laser, wait 30 seconds, and then re-apply DC power. If the fault fails to clear, contact SYNRAD
or a SYNRAD Authorized Distributor.

DB-9 connector

Symptom:

■ The built-in +5 VDC, 250 mA voltage output on Pin 5, DC Out, has been accidentally shorted to ground.

Possible Causes:

■ In the event that Pin 5, DC Out, is shorted to ground, the OEM v30 laser will not be damaged as the voltage regulator

is protected by a current-limiting circuit.

RJ45 connector

Symptom:

■ The built-in +15 VDC, 250 mA voltage output on Pin 2, DC Out, has been accidentally shorted to ground.

Possible Causes:

■ In the event that Pin 2, DC Out is shorted to ground, the OEM v30 laser will shutdown, but restarts automatically

once the short-circuit is removed.

Beam delivery optics

Symptom:

■ The laser appears to lose power over time; laser output power must be increased to maintain previous performance.

Possible Causes:

■ Beam delivery optics are coated by vapor residue or debris.

Troubleshooting (cont.)

Danger

serious

Ensure that DC power to the laser is turned off and locked out before inspecting optical
components in the beam path. Invisible CO2 laser radiation is emitted through the
lens. Corneal damage or blindness may result from exposure to laser radiation.

personal

injury

Shut down the laser and carefully inspect each optic in the beam delivery path, including the laser’s output coupler. Remem­ber that optics are fragile and must be handled carefully. If the optic requires cleaning, then refer to the Firestar v40 Opera-
tor’s Manual and use only recommended cleaning materials to prevent scratching delicate optical surfaces.

Caution

possible

personal

A risk of exposure to toxic elements, like zinc selenide, may result when certain optical
or beam delivery components are damaged. In the event of damage to laser, marking
head, or beam delivery optics, contact SYNRAD, Inc. or the optics manufacturer for
handling instructions.

injury

If the focusing optic is pitted, it must be replaced immediately. Because of the extremely high power density of Firestar lasers,
pits or debris on the lens may absorb enough energy from the focused beam to crack the lens. If this happens, other optics in
the beam path may be contaminated or damaged as well.

When the laser application requires air (instead of nitrogen or argon) as an assist gas, use breathing quality air available in
cylinders from a welding supply company. Compressed shop air contains minute particles of oil and other contaminants that
will damage optical surfaces and must be carefully filtered and dried before use as a purge or assist gas.

Warning

serious

personal

injury

Caution

possible

The use of aerosol dusters containing difloroethane causes “blooming”, a condition that
significantly expands and scatters the laser beam. This beam expansion can effect mode
quality and/or cause laser energy to extend beyond the confines of optical elements in
the system, possibly damaging acrylic safety shielding. Do not use air dusters containing
difloroethane in any area adjacent to CO2 laser systems because difloroethane persists
for long time periods over wide areas.

If you operate your laser or marking head in a dirty or dusty environment, contact
SYNRAD about the risks of doing so and precautions you can take to increase the
longevity of your laser, marking head, and associated optical components.
