1.4. Maximum Permissible Exposure and Nominal Ocular Hazard Distance
The Maximum Permissible Exposure (MPE) is the level of radiation to which, under normal
circumstances, persons may be exposed without adverse effects. The MPEs represent the maximum
906-0236-00 REV 8

5

1. Safety

level to which the eye or skin can be exposed without consequential injury and are related to thewavelength of the laser radiation, the pulse duration or exposure duration, and the tissue at risk.
The MPEs given in the following tables are informative and provided so that the integrator can calculate
the Nominal Ocular Hazard Distance (NOHD), perform a risk analysis and inform the user about the safe
usage of the product. However, exposure limits for the eye and the skin of employees in the work place
and the general public are in many countries specified in national laws. These legally-binding national
exposure limits might differ from the MPEs given in the tables below.
The NOHD is the distance from the output aperture beyond which the beam irradiance or radiantexposure remains below the appropriate MPE. Importantly, the NOHD is dependent upon the beam
waist size and the divergence of the beam. Therefore, the NOHD is dependent upon the opticalcomponents acting on the beam. The NOHDs given in the tables below are relevant only when the laser
is operated without external beam delivery attached. When beam delivery is attached it is the
responsibility of the integrator or end-user to recalculate the NOHDs. Further details of the safe use oflasers are given with IEC/ TR 60824-14 "Safety of laser products – Part 14: A user’s guide."

2.5.4. Cooling system
SR series lasers require a temperature stabilised recirculating coolant circuit in order to operatecorrectly.
The preferred coolant is deionised water or deionised water with anti-bacterial additive. See
Appendix E.
Important!
To prevent condensation on optical surfaces, the coolant temperature must be maintained
above the dew point.

The following look-up table defines minimum coolant temperatures (above the dew point) that avoid
condensation with respect to ambient temperature and relative humidity.

5. Routine maintenance
The SR series has been designed to be low maintenance. Internal routine maintenance procedures are
not required. The system's sealed construction and limited number of moving parts ensure trouble-freeand reliable operation.

5.1. General cleaning

WARNING
Laser radiation and electrical hazards
Use of controls or adjustments or performance of procedures other than those specified herein
may result in hazardous laser radiation exposure. This is a Class 4 (Class IV) laser and the beam isinvisible to the eye.
Please review all safety instructions and precautions given in the Safety chapter before
attempting to operate or service this system.
Always ensure that the laser system is switched off and isolated from the mains supply before
attempting any cleaning or maintenance procedures.

••

The external surfaces of the system can be cleaned with a mild detergent. It is advisable to use adamp cloth to facilitate the cleaning of the external cabinets, etc.
Take care not to allow entry of water into any of the electrical cabinets or onto the output window
or final beam delivery optic.

5.2. Pre-ioniser fuse replacement

DANGER
Risk of electric shock
Ensure that the equipment is disconnected from the mains supply before replacing the fuse.

1.
2.

Disconnect the equipment from the mains electrical supply.

2

1906-0236-00 REV 8

25

5. Routine maintenance3.

Remove the faulty fuse (PI).

PI

4.

Fit a replacement fuse of the same size and type.
Fuse specification: 20mm, T1A250V (Luxinar part number 552-0007-00).
5. Replace the cover and secure it with the fixing screw. Care should be taken when fitting the cover.
Ensure the pre-ioniser cable is not trapped or crushed when fastening.
Note: If the fuse fails again after replacement, this may indicate a more serious fault. For more
information and advice, contact Luxinar Aftersales.

5.3. Cooling system contamination
If the cooling water is contaminated with bacteria or has been treated with other chemicals it will benecessary to clean the cooling circuit:
The pH value, conductivity and dissolved solids levels can be measured using a portable meter. The
bacterial contamination level can be checked using a test kit. For more information and advice, contact
Luxinar Aftersales.
Pay particular attention to the instructions provided by the manufacturer of the NALCO water treatment
kit:
1. Drain off the contaminated cooling water.
Ensure that disposal of all the materials used in this product is conducted according to all local andnational regulations.
2. Flush the cooling water circuit with tap water by filling and draining once only.
3. Mix tap water with deionised water in a 1:1 ratio and fill the cooling water circuit.
4. Add a NALCO biocide water treatment kit and mix well with the cooling water.
5. Operate the system for two to four days, then drain off the cooling water.
6. Flush the cooling water circuit twice.
7. Fill the cooling system with fresh deionised water and add the contents of a fresh NALCO water
treatment kit.

5.4. Frost protection
If the cooling system or chiller which supplies the cooling for the laser system is located in an area
where the temperature may drop below 0°C, then the cooling circuit must either be equipped with awinter-proof heating tank to prevent the cooling water temperature dropping below 15°C or the coolant
must contain glycol antifreeze. For coolant details refer to Appendix E.

The weight of the laser head supply exceeds the single person lift limit of 18kg, as specified
in EN 61010-1:2010+A1:2019. Ensure a minimum of two people lift the laser head or thatsuitable lifting equipment is employed.

Suitable lifting points are the base of the laser resonator, the beam turning block and the internalbeam delivery module cover. Do not lift using the power feedback or shutter modules, if fitted, as
this can cause optical misalignment with a reduction in power or mode quality.

906-0236-00 REV 8

Place a suitable beam block or power monitoring device in the beam path. Do not place it close to
optical surfaces to avoid risk of contamination by evaporated material. Be aware that the beam
blocking material may create dangerous reflections.

WARNING
Hazardous laser radiation
Always wear protective eye wear matched to the emission wavelength and output power ofthe laser. Instruct all personnel in the vicinity to wear identical protective eyewear.

10. Mount the beam delivery and connect it to the laser output window using the prepared connector.
See section 6.2.6.

6.2. Unpacking, mounting and connections
Refer to section 2.5 for details of weights and dimensions.

6.2.1. Mechanical fixing
Secure the laser to the host machine using the three mounting feet on the base. Each mounting foot has
an M8 threaded hole and an open-ended slot suitable for an M8 bolt.
Mounting position dimensions are shown in the following figures.

6. Installation

SR 15e, 25i, 25x

To ensure correct operation of the standard version, it must be mounted in one of the approved
orientations identified by the check mark in the following figure.

WARNING
Risk of shutter malfunction or failure
For shutter and power feedback versions, the A orientations must not be used. Safe operation of
the shutter requires that the laser is mounted horizontally with the feet underneath.

CAUTION
Risk of optical damage due to vertical orientation
Vertical mounting, as shown by orientations B and C, can result in premature failure of laser
optics and should be avoided. Mounting with the output window on top of the laser, shown inorientation B, is totally prohibited.

Power feedback version
For the power feedback version, the axis of the output beam is offset in the horizontal plane whencompared with the standard version or shutter version. The horizontal beam axis with respect to themounting feet is shown in the following figure.

Note: For the power feedback version, the beam will be tilted downward in the vertical plane by 2.8± 0.4mrad. In the horizontal plane the beam may have an angular deviation from the optical centre-lineof up to ± 1.75mrad.

6.2.3. Coolant connections and pipework
If the optional Luxinar DC power supply is fitted, the coolant must flow through the power supply before
the laser.
For the shutter and power feedback versions, the coolant enters the laser via the shutter module.

Figure 33 - Coolant connections and flow direction

906-0236-00 REV 8

Coolant inlet and outlet connectors are marked with the following symbols (direction depends on thelabel location):• Coolant in•

Coolant out

Important!
Materials used in the external cooling circuit must be chosen to avoid corrosion. Never use
aluminium, zinc, mild steel or cast iron components. Suitable materials are stainless steel,copper, copper alloys and opaque plastics. Only use pipework that is impervious to light in orderto reduce the possibility of bacterial contamination of the cooling system.
The coolant temperature must be kept above the dew point in order to prevent formation ofcondensation on internal laser components.
Completely drain the cooling system before shipment or storage.

6.2.4. Beam delivery optics purge gas
If the internal or external beam delivery is contaminated with fumes, water vapour or debris then thesecontaminants can absorb the laser energy and cause laser power fluctuations and steering of the laser
beam. In severe cases, laser optics can be contaminated and damaged.
The laser internal beam delivery is fitted with an optics purge system for use with contaminant-freecompressed air or nitrogen.

Purge gas exhaust

Figure 34 - Internal optics purge gas connector

A non-return check valve is fitted to the internal beam delivery. The check valve opens and allows theexcess purge pressure to escape.
Once the purge pressure has dropped to the correct pressure, the valve will close automatically,
preventing dust, moisture and contaminants from entering the optical system.

6.2.5. Electrical power connections
The laser requires a 50VDC power supply, either supplied locally or available from Luxinar. For
specifications refer to section 2.5.1.
The connecting cable cross-section depends on the laser model and cable length. Refer to the following

Clamp the cables securely in the terminals using the two clamp screws on each terminal.
Replace the cover and secure it with the securing screw. Care should be taken when fitting thecover. Ensure the pre-ioniser cable is not trapped or crushed when fastening.

6.2.6. Beam delivery

CAUTION
Risk of damage to the laser output window mountThe laser output window mount is not capable of supporting a beam delivery. Always provide
strong and stable mechanical support for the beam delivery and other external optics.

Important!
Remove the blanking cap from the output window before attempting to attach the beam
delivery. Care should be taken when fitting the cover.

There are two approved methods for attaching the beam delivery system to the laser output:
1. Attach the beam delivery to the four M5 mounting holes on the output window mount.

906-0236-00 REV 8

6. Installation

2.

Insert the beam delivery tube directly into the output window mount and secure it by an M6 grubscrew.

Note: Shutter and power feedback versions have a visible light laser diode pointer to assist with beam
delivery alignment. The rated power of the laser diode pointer is 4mW.
Take appropriate precautions when using the laser diode pointer to align the beam delivery.

WARNINGClass 3R visible laser radiation
Avoid eye exposure to direct and scattered radiation.

6. Installation

906-0236-00 REV 8

7. Transport and recommissioning
Before transporting the laser, observe the following precautions:• Completely drain the laser cooling system to prevent damage during shipping. Use clean compressed
air, at a maximum pressure of 2bar, to blow out all traces of coolant in the cooling system pipework.
Failure to remove coolant from the system prior to transport can cause damage to the laser.
Damage caused in this way will invalidate the warranty.
• If the external beam delivery has been removed, replace the output window protection cap toprevent damage or contamination during shipping.

8. Interfacing
User interface connections for SR series lasers are made through the 25-pin and 15-pin connectors on
the rear panel. Pin connections depend on the laser version.
Important!
Under certain conditions, it may be possible for power cables carrying high voltages and currents
to emit electrical noise levels that may interfere with control cable signals.
To eliminate the possibility of interference, control signal cables must be screened and routed
along a different path to power cables.

The dual channel safety critical approach [EN:13849 Performance Level D] requires the system to react
to system conditions as follows:• When the EXTERNAL_INTERLOCK is disabled, SHUTTER_ENABLE and RF_ENABLE must also
be disabled by the machine controller.
• When restarting the system with EXTERNAL_INTERLOCK enabled, the control signal startup
timing sequence must be followed.

8.6. Status indicators
The operational status of the laser is displayed by status indicator lamps on the laser rear panel.

Appendix A. Power feedback programming
A.1. Control modes
A.1.1. External Pulse Width Modulation (PWM) mode
External PWM mode controls laser output power using a signal from a modulation source supplied by
the user. The mark-space ratio of the signal waveform controls the output power, within the modulation
limits of the laser.
Note: This is the default operating mode. The laser is shipped with this mode activated.
The key control features of this mode are:• RS232 commands may be used to interrogate the laser (or change mode) but will not otherwise
affect the power output.
• The trigger input is not used in this mode.
• The trigger delay is not available in this mode.
• The RF Enable input must be high (5V) to activate the RF amplifier.
• The Shutter Enable signal must be high in order to activate the shutter.
• If an error condition occurs, for example, a low water flow, the laser will fall back to an RF
Disable condition, disabling modulation input to the RF Amplifier and closing the shutter.
Certain errors can be reset by applying a rising edge signal to the RF Enable input. For example, if
the shutter failed to open or failed to close.

A.1.2. Internal open loop mode
RF modulation is controlled by varying the pulse-width or frequency using RS232 commands. Powerdemand is also set using an RS232 command.
Laser power output is controlled by one of two parameter combinations:• Vary power demand and frequency.
• Vary power demand and pulse width.
Input parameters depend on the laser model.
The key control features of this mode are:
• The controller does not vary the modulation.
• The trigger input or a software command may be used to start the laser.
• The RF Enable input must be high (5V) to activate the RF amplifier.
• The Shutter Enable signal must be high in order to activate the shutter.
• If a fault condition occurs, the laser stops operating and the shutter closes.
• Errors can be reset by sending RS232 commands Goto Standby, Goto Run, or Start Laser.
Alternatively, the trigger input can be switched to low (0V).

A. Power feedback programming

A.1.3. Internal closed loop mode
Laser output power is controlled using the same input signals as internal open loop mode but with theaddition of a feedback signal from the power feedback module. The closed loop algorithm applies fineadjustments to either pulse width or frequency in order to stabilise laser output power at the demanded
level.
The key control features of this mode are:
• The controller automatically varies the laser modulation to control the laser power.
• The trigger input or a serial command may be used to start the laser.
• The RF Enable input must be high (5V) to activate the RF amplifier.
• The Shutter Enable signal must be high in order to activate the shutter.
• If a fault condition occurs, the laser stops operating and the shutter closes.
• Errors can be reset by sending RS232 commands Goto Standby, Goto Run, or Start Laser.
Alternatively, the trigger input can be switched to low (0V).

A.1.4. NC power control mode
Laser output power is changed by varying the voltage on the NC input, connector U2, pin 13. The power
can be controlled linearly from 20W up to the maximum selected in the current program. One volt will
give 20W and the maximum ten volts will give the maximum power defined by the user. During NC
power control operation, the minimum output power is 20W. If the control voltage falls below one volt,or below the minimum power threshold, the laser will switch off. In NC power control mode, Closed
loop feedback is used to stabilise the selected power level.
• The controller varies the modulation to control the power level in response to the NC demand input.
• The trigger input or a serial command may be used to start the laser.
• The RF Enable input must be high (5V) to activate the RF amplifier.
• The Shutter Enable signal must be high in order to activate the shutter.
• If a fault condition occurs, the laser stops operating and the shutter closes.
• Errors can be reset by sending RS232 commands Goto Standby, Goto Run, or Start Laser.
Alternatively, the trigger input can be switched to low (0V).

A.2. Overview of controllers
A.2.1. OEM-supplied controller
For fully integrated machines, the machine controller also controls and monitors the laser directly. For
full interfacing details see Chapter 8.

A.2.2. RS232 controller (shutter version and power feedback version only)
The machine controller provides serial interface commands using the RS232 protocol. For full details ofserial interface commands, refer to the Luxinar serial interface specification (part number 906-0109-00).

A.2.3. OEM-supplied controller with Luxinar TTL converter
In order to minimise the effect of RF interference in the control circuitry, it is required that control
connections to the laser are made using the RS422 protocol provided by a Luxinar TTL converter unit.
This unit converts 5V TTL signal levels to RS422 levels.
If the user is unable to generate RS422 signals directly, the Luxinar TTL converter will generate theappropriate RS422 signals from a TTL source.

A.2.4. Luxinar industrial controller
The industrial controller is a stand-alone programmable controller that can operate the laser in any of
the operating modes. The controller also has additional safety interlock features and programmablepulse output options, including:• Continuous
Continuous operation at a set pulse period (PP) and pulse width (PW).
• ToneBurst
Laser output is switched on and off at set intervals in a repetitive sequence.
• StepBurst
Three ToneBurst pulse groups are executed sequentially.
• Perforate
A number of pulses with pre-defined pulse width are executed at intervals triggered by a machinetacho signal.
• ScribeGroups of pulses with pre-defined pulses are executed at intervals triggered by a machine tachosignal.

NALCO RS200 and 7330 are completely compatible with glycol. The glycol should be without any
inhibitor (concentration 30–35% glycol in demineralised water).
The use of inhibitors, biocides, other substances or hardness stabilisers other than the specialist
NALCO kit may cause premature failure of the laser. It is the user's responsibility to ensure that the
specification of any alternative additive is equivalent to that of the NALCO additive.
Cooling system maintenance
After six months of operation, drain off the coolant and refill with fresh water treated with theappropriate NALCO kit or equivalent anti-bacterial product, as specified in Table 24.
Ensure that the disposal of all the materials used in this product is conducted according to all local
and national regulations.

Appendix G. TTL to RS422 converter
The optional TTL converter changes TTL-level signals from the OEM machine to RS422-level signals thatprovide better noise protection from RF and other sources of interference.

Figure 46 - TTL to RS422 converter unit

G.1. Mounting
Mount the converter unit securely within the OEM machine by means of the four mounting holes on thebase.

G.2. Configuration
The converter contains a 2-position jumper to enable or disable the internal RF Enable signal. If theinternal signal is disabled, the user must provide an external RF Enable signal.
Note: An external RF Enable signal provides an important additional safety feature.
To change the jumper position, remove the TTL unit cover and change the position of the jumper, as
shown in the following figure.

energy levels that may interfere with control signal cables. To eliminate the possibility ofinterference, cables carrying control signals should be routed along a different path to power
cables.

The power supply is provided with a 6mm² mains supply cable. If this cable needs to be replacedwith a longer cable, ensure the replacement cable is of the correct rating for the power supply.

DANGER
Risk of electric shock or severe damage to the equipment
Ensure that the equipment is disconnected from the mains supply before making thisconnection.

To replace the cable:
1. Remove the access panel on the rear of the power supply by removing the seven screws.

Remove the supplied cable from the connector and replace it with the alternative cable ineither single-phase or bi-phase configuration.
Important!
An earth connection is essential. Ensure that the earth wire is connected before
connecting the mains supply. For improved EMC performance, Luxinar recommends
using a screened cable and terminating the cable screen to the gland.

READY
The three-phase mains supply is correctly connected.
Note: The power supply uses a soft-start circuit during power up and the FAULT indicator will turnon momentarily during this time. This is normal.
If the mains supply is switched on and off too often, the soft-start resistors heat up and the FAULT
indicator tuns on. If this happens, switch off the mains supply and wait for five minutes for the softstart resistors to cool down.

Uok
Once the PSU Enable signal is applied, the DC output will turn on. The output voltage is internallycompared to the set reference voltage. If this is correct, the Uok indicator will turn on.
Note: If the external voltage is not correct, the DC output is turned off and the FAULT indicator turns
on. Check the external wiring.
