Touch Probe Systems for Machine Tools

Touch probes from H EID EN H AIN w ere

conceived for use on m achine toolsin

particular m illing m achines and m achining

centers. Touch probes help to reduce setup

tim es, increase m achine usage tim e and

im prove the dim ensional accuracy of the

nished w orkpieces. Setup, m easuring and

m onitoring functions can be perform ed

m anually orin conjunction w ith m ost

CN C controlsunder program control.

Workpiece measurementH EID EN H AIN offers TS triggering touchprobesfor w orkpiece m easurem ent righton the m achine. The probe is inserted in

the tool holder either m anually or by the

tool changer. They enable you to use the

probing functions offered by your N C

control to autom atically or m anually

perform the follow ing functions:

W orkpiece alignm ent

W orkpiece presetting

W orkpiece m easurem ent

D igitizing or inspecting 3-D surfaces

Tool measurementSuccessful series production hinges on the

prevention of scrap or rew ork and the

attainm ent of consistently good

w orkm anship. The tool is a decisive factor

here. W ear or tool breakage that go

undetected for extended periods,

especially during unattended operation,

result in defective parts and unnecessarily

increase costs. Therefore, exact

m easurem ent of tool dim ensions and

periodic control of w ear are absolutely

essential. For tool m easurem ent on the

m achine, H EID EN H AIN offers the TT three-

dim ensional touch probe and the TL laser

system s.

W ith the TT triggering touch probes,thecontact plate is defl ected from its rest

position, sending a trigger signal to the N C

control, during probing of the stationary or

rotating tool.

The TL laser systemsoperate w ithout anycontact. A laser beam probes the length,

diam eter or contour of the tool. Special

m easuring cycles in the N C control

evaluate the inform ation.

Application ExamplesW orkpiece A lignm ent

Exact w orkpiece alignm ent parallel to the

axes is particularly im portant for partially

m achined w orkpieces to ensure that

existing datum surfaces are in an

accurately de ned position. W ith the TS

touch probe system s from H EID EN H AIN

you can avoid this tim e consum ing

procedure and do w ithout the clam ping

devices otherw ise required.

The w orkpiece is clam ped in any

position.

The touch probe ascertains the

w orkpiece m isalignm ent by probing a

surface, tw o holes, or tw o studs.

The C N C com pensates for the

m isalignm ent by rotating the coordinate

system . It is also possible to

com pensate for it m echanically by

rotating the table.

Selection Guide

The TS w orkpiece touch probes from

H EID EN H AIN help you perform setup,

m easuring and inspection functions directly

on the m achine tool.

The stylus of a TS touch trigger probe is

defl ected upon contact w ith a w orkpiece

surface. At that m om ent the TS generates

a trigger signal that is transm itted either by

cable or over an infrared beam to the

control. The control sim ultaneously saves

the actual position values as m easured by

the m achine axis encoders, and uses this

inform ation for further processing. The

trigger signal is generated through a w ear-

free optical sw itch that ensures high

reliability.

Principle of FunctionSensor

TS 2xx, TS 44x, TS 64xTouch probes from H EID EN H AIN operate

w ith an optical sw itch as sensor. A lens

system collim ates the light generated from

an LED and focuses it onto a differential

photocell. W hen the stylus is defl ected,

the differential photocell produces a trigger

signal.

The stylus of the TS is rigidly connected to

a plate integrated in the probe housing on a

three-point bearing. The three-point bearing

ensures the physically ideal rest position.

Thanks to the non-contacting optical

sw itch, the sensor is free of w ear. In this

w ay, H EID EN H AIN touch probes ensure

high long-term stability w ith a constantly

probe repeatability even after very m any

m easuring processes, as for exam ple w ith

in-process applications.

sensors

TS 740The TS 740 uses a high-precision pressure

sensor. The trigger pulse is obtained through

force analysis. The forces acting during

probing are processed electronically. This

m ethod provides extrem ely hom ogeneous

probing accuracy over 360.

W ith the TS 740, the de fl ection of the stylus

is m easured by several pressure sensors

that are arranged betw een the contact

plate and the probe housing. W hen probing

a w orkpiece, the stylus is defl ected so that

a force acts on the sensors. The signals

generated are processed and the trigger

signal is produced. The relatively low probing

forces provide high probing accuracy and

repeatability, w hile offering precise trigger

characteristics in all directions.


13/7213

Probe repeatabilityProbe repeatability is the dispersion of the

results derived from repeated probing

from the same direction.

Influence of probe styliStylus length and stylus m aterial directly

touch probe. Styli from H EID EN H AIN

ensure a probing accuracy grade of better

than 5 m .

Probe accuracyThe probe accuracy speci es the error

resulting from probing a test com ponent

from various directionsat 22 C am bienttem perature.

The probing accuracy also includes the

effective ball radius. The effective ball radius

is calculated from the actual ball radius and

the stylus de fl ection required to produce

the trigger signal. This also includes stylus

bending.

Touch probes are m easured for accuracy

on precision m easuring m achines at the

H EID EN H AIN plant.

The TS 740triggering touch probe ischaracterized particularly by high probing

accuracy and repeatability. These features,

together w ith its low probing force, m ake

the TS 740 suitable for very dem anding

m easuring tasks on m achine tools.

Signal Transm ission

TS 220, TS 230, TS 249Touch Probes with Signal

Transmission by Cable

For these touch probes, both the pow er

supply and the trigger signal are conducted

over the touch probe's cable.

The m achine operator inserts the TS 220,

TS 230 touch probes by hand into the

spindle. The spindle m ust be locked before

the touch probe can be inserted (spindle

stop). The CN C's probing cycles can run

w ith both vertical and horizontal spindles.

Pow er supply

Trigger signal

TS 44x, TS 64x, TS 740Touch Probes with InfraredTransmission of the TriggerSignal

The TS 44x, TS 64x and TS 740 touch

probes transm it the trigger signal through

an infrared light beam . This m akes them

ideal for use on m achines w ith autom atic

tool changers.

Infrared beamThe infrared transm ission is established

betw een the touch probe and the SEtransm itter/receiver unit. The follow ing

transceivers are available:

SE 540 for integration in the spindlehead

SE 640 for integration in the m achine'sw orkspace

SE 642 as com m on SE for w orkpieceand tool touch probes

They can be used in any com bination w ith

the TS 44x, TS 64x and TS 740.

The infrared transm ission is tolerant to

noise and even w orks by refl ection. It

therefore covers a very broad range ofapplications. For exam ple, the TS 64x can

be used both in vertical and horizontal

spindles as w ell as in sw ivel heads. An

even greater infrared transm ission range

can be realized by com bining tw o SE 640s

through an A PE 642 interface unit.

The infrared beam transm its several

signals: The start signalactivates thetouch probe. W ith the ready signalthetouch probe indicates that it is ready for

operation. A defl ection of the stylus

produces the trigger signal.If the TS 64x/

TS 740's battery capacity falls below 10 % ,it transm its a battery warning.The fallingedge of the start signal sw itches the touch

probe off again.

Infrared Transm ission Range

Transmission areaThe transm ission areas betw een the S E

transm itter/receiver unit and the touch

probes have a lobe form . In order to ensure

an optim um signal transm ission in both

directions, the transceiver should be

m ounted so that the touch probe is w ithin

this range during all operation positions. If

the infrared transm ission is disturbed or

the signal becom es too w eak, the SE

noti es the CN C through the ready signal.

The size of the transm ission range

depends on both the touch probe and the

transceiver used w ith it.

Transm itter/Receiver U nit

The S E transceiver is to be m ounted so

that it rem ains w ithin the transm ission

range of the touch probe over the

m achine's entire range of traverse.

SE 540 transmitter/receiver unitThe S E 540 is intended for integration in

the spindle head. Except for a few cases,

for exam ple on m achines w ith quills, this

ensures transm ission on m achines w ith

very large traverse ranges or w ith sw ivel

heads. The transm ission range of the

infrared signal is appropriate to the

m ounting location. Because the SE 540 is

alw ays above and to the side of the TS,

H EID EN H AIN recom m ends using touch

probes w ith +30 transm ission angle. The

m achine m ust be designed to support the

SE 540.

SE 640, SE 642 transmitter/receiver unitThe S E 64x is m ounted at a suitable

location in the m achines w orkspace. It is

also easily to retro t. Thanks to its high

IP 67 degree of protection, it can also

tolerate coolant. A holder to facilitatem ounting is available as an accessory.

W hen m ounting the SE 642 it is im portant

to note that it can com m unicate both w ith

the TS w orkpiece touch probe and w ith the

TT 449 tool touch probe. The touch probes

very large angular range of transm ission

(up to 7 m w ith the TS 640) allow s reliable

transm ission to m achines w ith long axes.

For special applications, for exam ple very

large m achines, the transm ission range can

be enlarged by installing a second SE 640.

The connected APE 642 interface electronics

unit evaluates the infrared signals so thatthe N C receives only one trigger signal

regardless of the w orking range in w hich

the touch probe is located.

Styli

Styli for TSH EID EN H AIN offers probe styli w ith various

ball-tip diam eters and stylus lengths. All styli

are attached to the TS touch probes w ith an

M 3 thread. Starting from a ball-tip diam eter

of 4 m m , a rated breaking point protects

the touch probe from m echanical dam age

caused by operator error. The T404 and T424

styli are included w ith the TS touch probe.

W ith the aid of the adapter provided w ith

delivery, M 4 styli are also usable on the

TS 249. By using the coupling joint, theTS 249 can be rotated into position in order

to align asym m etric or cuboid probe

Selection Guide

Tool m easurem ent on the m achine

shortens non-productive tim es, increases

m achining accuracy and reduces scrapping

and rew orking of m achined parts. W ith the

tactile TT touch probes and the contact-free

TL laser system s, H EID EN H AIN offers tw o

com pletely different possibilities for tool

m easurem ent.

W ith their rugged design and high degree

of protection, these tool touch probes can

be installed directly w ithin the m achine

tool's w ork envelope.

TT touch probesThe TT 140 and TT 449 tool touch probes are

touch trigger probes for the m easurem ent

and inspection of tools. The TT 140 features

signal transm ission by cable, w hile the

TT 449 com m unicates w irelessly over an

infrared beam w ith the SE 642 transm itter/

receiver unit.

The disk-shaped probe contact of the TT is

defl ected during physical probing of a tool.

At that m om ent the TT generates a trigger

signal that is transm itted to the control,

w here it is processed further. The trigger

signal is generated through a w ear-free

optical sw itch that ensures high reliability.

The probe contact is easy to exchange. The

connection pin to the touch probes contact

plate features a rated break point. This

protects the touch probe from physical

dam age due to operator error.

TL laser systemsThe TL M icro and TL N ano laser system s

can m easure tools at the rated speed

w ithout m aking contact. W ith the aid of the

included m easuring cycles you can

m easure tool lengths and diam eters,

inspect the form of the individual teeth and

check for tool w ear or breakage. The

control autom atically saves the results of

m easurem ent in the tool table.

The m easurem ent is very fast and

uncom plicated. U nder program control, the

N C control positions the tool and starts the

m easuring cycle. This is alw ays possible:

before m achining, betw een tw o m achining

steps, or after m achining is done.

The axially focused laser beam m easures

tools as sm all as 0.03 m m in diam eter at a

repeatability of up to 0.2 m .

TT Touch Probes for Tool Measurement

Together w ith the m easuring cycles of the

CN C control, the TT tool touch probes

enable the TN C to m easure tools

autom atically w hile they are in the m achine

spindle. The control saves the values

m easured for tool length and radius in the

central tool le. By inspecting the tool

during m achining you can quickly and

directly m easure w ear or breakage to

prevent scrap or rew ork. If the m easured

deviations lie outside the tolerances, or if

the m onitored life of the tool is exceeded,

the control can lock the tool or

autom atically insert a replacem ent tool.

W ith the TT 449, all signals are transm ittedto the control via infrared beam .

Advantages:

G reatly increased m obility

Fast installation at any location

U se also on rotary and tilting axes

Your benefit:W ith the TT 140 or TT 449tool touch probe you can have your CN C

m achine operate unattended w ithout losing

accuracy or increasing scrap rates.


37/7237

Principle of Function

SensorTouch probes from H EID EN H AIN operate

w ith an optical sw itch as sensor. A lens

system collim ates the light generated from

an LED and focuses it onto a differential

photocell. W hen the probe contact is

defl ected, the differential photocell produces

a trigger signal. The probe contact of the TT

is rigidly connected to a plate integrated in

the probe housing on a three-point bearing.

The three-point bearing ensures the

physically ideal rest position.

W ith its contact-free optical sw itch, the

sensor operates w ithout w ear to guarantee

the high long-term stability of H EID EN H AIN

touch probes.

RepeatabilityFor w orkpiece m easurem ent, the

reproducibility of the probing process is of

m ajor im portance. The probe repeatability

speci es the error resulting from repeatedly

probing a tool from one direction at 20 C

am bient tem perature.

The probing accuracy of a touch probe is

m easured at H EID EN H AIN on precision

m easuring m achines.

M ounting

The tool touch probes feature IP 67

protection and can therefore be xed

w ithin the w orking space of the m achine.

The TT is m ounted w ith tw o xing clam ps

or on an accessory space-saving m ounting

base.

The TT w ith 40-m m probe contact should

be operated vertically to ensure reliable

probing and optim um protection against

contam ination. Like the cuboid probe

contact, the 25 m m diam eter SC02 probe

contact can also be operated w hen

m ounted in a horizontal position.

D uring w orkpiece m achining, the TT m ust

be sw itched off to ensure that the vibrations

that accom pany norm al m achining do not

trigger a probe signal and cause an

interruption. The w orking space of the

m achine tool should be lim ited in order to

prevent collision w ith the tool touch probe

during m achining.

Probing

The hardened probe contact of the TT tool

touch probe perm its direct probing of the

tool as it rotates opposite to the cutting

direction. Speeds of up to 1 000 m in1 are

perm issible depending on the tool diam eter.

The probe contact is quickly exchanged:

it is sim ply screw ed onto the touch probe

through a t.

The m axim um perm issible de fl ection of

the probe contact is 5 m m in any direction.

The m achine m ust stop m oving w ithin this

distance.

The probe contact of the TT features a

rated break pointin order to protect thetouch probe from physical dam age due to

operator error. The rated break point is

effective in all probing directions. A rubber

sleeve offers protection from splinters.

A defective connection pin can easily be

replaced w ithout requiring readjustm ent of

the TT.

Optical deflection displayTw o LED s on the TT 140 additionally

indicate de fl ection of the probe contact.

O n the TT 449, the condition of the touch

probes is visible through LED s on the

SE 642 transm itter/receiver unit. This is

especially useful for testing correct

operation. You can see at a glance w hether

the TT is currently defl ected.

Probe contactsTo probe milling cutters, the tool touchprobes are equipped w ith a disk-shaped

probe contact w ith 40 m m diam eter

(exam ple). A disk-shaped probe contact

w ith a 25 m m diam eter is available as an

accessory. Because of its sm all w eight, it

is particularly recom m ended for horizontal

m ounting of the TT.

The TT tool touch probe can also be used

to calibrate lathe tools(exam ple). The atsurfaces of a cuboid probe contact

(available as an accessory) are contacted

by the edges of the lathe tool. This m akes

it possible to regularly inspect tools in N C

controlled lathes for breakage and w ear in

order to ensure process reliability.

The probe contacts can be ordered

separately for replacem ent. The can be

easily replaced, w ithout requiring

readjustm ent of the TT.

Tool m onitoring w ith a TL laser system is a

very exible solution. The contact-free

optical m easurem ent enables you to check

even the sm allest tools rapidly, reliably and

w ithout collision. Even the m ost sensitive

tools are com pletely secure from dam age.

The precise determ ination of the length

and radius at the rated shaft speed ensures

your high quality of production. At the

sam e tim e this integrated tool setting w ith

autom atic updating of tool data elim inates

the need for separate tool setting, reducing

costs and non-productive tim es.

Tool m onitoring occurs at the rated shaft

speed in the real clam ping system , and as

such under real operating conditions. Errors

on the tool, spindle and holder can be

im m ediately detected and corrected. Every

single tooth is m easured at the highest

speed. Even the geom etry of special tools

can autom atically be checked on the

m achine for deviations.

Laser Systems for Tool Measurement

The continual process inspection w ith

m onitoring of the tool data detects w ear,

tooth breakage and tool breakage before

dam age occurs. This ensures consistent

production quality, avoids subsequent

dam age, and reduces the cost of scrapped

or rew orked parts. The m easuring cycles

operate autom atically, ensuring optim um

m onitoring even during unattended

operation.

The TL laser system s guarantee reliable

tool m onitoring, high m easuring accuracy

and precise inspection for w ear and tear.

They offer the follow ing bene ts:

Reduced non-productive tim es

U nattended operation

Less scrap

Increased productivity

Consistently high quality of production

Mounting attitudeThe TL laser system s ful ll the

requirem ents for IP 68 and can therefore

be xed directly in the m achines w orking

space. For sm ooth operation, even w ith

coolant and chips, the transm itter and

receiver feature a pneum atically activated

sealing system . The additional introduction

of sealing air provides a very high degree

of protection against contam ination.

The TL laser system s can be m ounted in

both upright and resting positions on or

next to the m achine table. They m ust be

m ounted in a stable enough m anner to

guarantee high repeatability. The cutting

edge should rotate in the appropriate

direction for avoiding bothersom e refl ections

and refractions during m easurem ent by

the laser beam .

The w orking space of the m achine tool

should be lim ited in order to prevent

collision w ith the laser system during

m achining.

Adjusting the TLIn order to achieve the best possible

repeatability, the laser system m ust be

m ounted exactly parallel to tw o N C axes.

For upright m ounting on the m achine table,

the horizontal alignm ent is ensured by the

m ounting surface. The m ounting tolerances

are included in the dim ension draw ings.

D eviations in the parallelism are particularly

noticeable as linear errors w hen m easuring

the length of very different tool diam eters.

It is therefore recom m ended that the

length of eccentric tools (e.g. end m ills,

face-m illing cutters) be m easured on the

outside radius outside of the tool axis.

Protection from Contam ination

The application of laser system s directly on

m achine tools requires effective m easures

to protect the sensitive optical system of

the laser light barrier.

Mechanical protectionThe optics of the laser system s are

perfectly sealed against coolant and chips

by contam ination shutters w ith an

integrated m echanical seal system . The

seal releases the optical system only for

the duration of the m easurem ent. The seal

is actuated pneum atically by the DA 301 TL

com pressed air unit.

Sealing airThe transm itter and receiver of the laser

light barrier are protected by very clean

sealing air from the DA 301 TL com pressed

The TL laser system s operate as high-

precision light barriers w ithout any contact.

A laser light source (protection class 2 as

per IEC 825) em its a laser beam . The

opposing receiver unit detects the laser

beam and so captures every interruption.

For any change in statussuch as w hen a

tool interrupts the laser beam or is

rem oved againthe integral electronics

generate a trigger pulse for a de ned

duration. This dynam ic signal DYN is

transm itted to the N C control, w here it is

used for capturing the position value. In

addition, the laser system outputs the

static signal STA for the duration that the

laser beam is interrupted.

CalibratingBefore m easurem ent w ith the TL laser

system can be started, the system m ust

be calibrated, m eaning that the exact

position of the trigger points relative to the

m achine coordinate system m ust be

determ ined. A reference tool, available as

an accessory, is used for this purpose. It

has a characteristic shape for calibration,

w ith a cylindrical dow el pin and a stepped

inspection diam eter for m easurem ent in

the positive and negative Z axis directions

(for determ ining the exact position of the

center of the laser beam in Z). The

reference tool is clam ped into the tool

holder, and its length, diam eter and height

are m easured very exactly. A cylindrical

dow el pin suf ces for sim ple applications.

The best possible runout is to be ensured

for the calibration m easurem ent.

Operating modesThe operating m ode of the laser system is

de ned over the receiver-enabling inputs 1

and 2 (EN ABLE 1/EN ABLE 2). The m easuring

signals autom atically put the receiver in the

appropriate operating m ode.

D uring inspection of individual teeth,each available tooth generates an output

pulse of de ned duration. The pulse length

and the num ber of teeth de ne the basic

speed. In the event of errora m issing

tooth or a tolerance errorthe dynam ic

output signal (DYN ) stays at low level for

m ax. 100 seconds.

In the measuringm ode, every change oflight causes an output signal D YN w ith a

de ned duration of 20 m s. The positive edge

is evaluated. The device is sw itched betw een

pushingand pullingm easurem ent over

the receiver-enabling input 2 (EN ABLE 2).

Optical status indicatorLED s on the receiver side of the laser

system m ake a rapid diagnosis of the

status possible. This w ay the operator sees

at a glance w hether the laser beam path is

O K, w hether a dynam ic trigger signal is

being output, and the current operating

m ode of the laser system .

Probing used toolsThe optically scanning laser system can of

course not distinguish betw een the actual

tool to be m easured and any attached chips,

coolant coating or falling drops of coolant.

In order to avoid faulty m easurem ents, the

tool should therefore be cleaned before

m easuring. This can be done by spinning

off any particles at a high rotational velocity

or by blow ing them off w ith air. The TL laser

system s feature an integral blow ing feature

for this, w hich can be used to clean the

tool before and during a m easuring cycle.

Caution:N ever m ix types or m odels of batteries!

The TS 440, TS 64x, TS 740and TT 449touch probes w ith infrared transm ission

are pow ered by tw o batteries (rechargeable

or nonrechargeable) w ith a rated voltage of

1 to 4 V. The service life depends heavily on

the type and m odel of batteries used (see

table for exam ples). The typical service life

data show n in the speci cations apply only

to the lithium batteries included in delivery.

The touch probe electronics autom atically

detect the type of batteries used. If the

battery capacity falls below 10 % , the SE

transm its a w arning to the control and a

red LED sim ultaneously lights up on the SE.In order to m inim ize the current

consum ption, the touch probe sw itches to

the stand-by m ode w hen the off signal is

transm itted, or at the latest, 30 m inutes

after the last probing. Eight hours later it

sw itches to the sleep m ode. You m ust then

take a longer startup tim e into account

TS 444 Energy G eneration through Air Turbine G enerator

The TS 444touch probe w ith infraredtransm ission has an air turbine generator

for pow er generation. Additional

rechargeable or nonrechargeable batteries

are not required.

StructureThe air turbine generator consists of an air

turbine, the actual generator and high-

pow er capacitors for energy storage.

Com pressed air that is supplied through

the spindle is required for operating the

turbine. The com pressed air can also be

used for cleaning the w orkpiece. C harging

the capacitors and cleaning the w orkpiece

are thus com bined in one w ork step. This

elim inates such additional idle tim e.

Principle of functionAfter inserting the TS 444 touch probe, the

high-pow er capacitors are charged by the

air turbine generator. This can be done

w hen the touch probe m oves from the tool

changer to the m easuring position, and

also w hen the w orkpiece is cleaned w ith

com pressed air.

Charging timesThe charging tim es of the capacitors

depend on the available air pressure: The

higher the pressure, the shorter the

charging tim e (see diagram ).

Operating timeW hen the capacitor is fully charged, the

TS 444 is ready for 120 seconds of

continuous operation. The battery w arning

signal reports that the capacitors need to

be recharged.

Requirements for compressed airqualityThe air turbine generator can already

operate at a m inim um pressure of

2 x 105Pa. An operating pressure betw een

5.5 x 105 and 8 x 10 5 Pa is recom m ended

for effective charging. The com pressed air

does not need to be specially cleaned.

InterfacesTS, TT Touch Probes

Touch Probe with Infrared Transmission

The TS 440, TS 640, TS 740and TT 449touch probes are sw itched on by the C N C

over the SE. The rising edge of the startsignal Ractivates the TS, and the fallingedge sw itches it off.

The TS 642touch probe is activated byinserting it in the spindle by a m icrosw itch

integrated in the taper shank.

The SE uses the ready signal Bto reportto the control that the touch probe is

activated and w ithin the reception area of

the SE. The w orkpiece can now be probed.

The delay t w hen sw itching the probe on or

off depends on the distance betw een the

SE and TS, as w ell as the m ode of the

touch probes pow er supply. Subsequent to

the initial activation (w hen the TS is in

standby m ode) the typical value for

activation is 250 m s, and for deactivation

350 m s (1 000 m s for the m ax. distance).

W hen activating the probe after a longerinterval (m ore than 8 hoursthe TS is in

the sleep m ode), the delay can be up to

3 seconds. If the touch probe does not

respond, the SE aborts the sw itch-on/off

attem pt after 3.5 seconds.

TL Laser System s, DA 301 TL

TL inputsThe CN C activates the laser system

through three enabling lines:

The transmitter enabling signal 0(EN ABLE 0) activates or deactivates the

transm itter and sw itches the laser beam on

or off. To reduce the pow er loss (heat

generation) to a m inim um and increase

service life, the laser diode is activated only

during the m easuring cycle.

The receiver enabling signals 1and 2(EN ABLE 1 and EN A BLE 2) determ ine the

operating m ode of the laser light barrier

depending on the respective m easuring

cycle.

Signal level:U H = 24 V at 15 m A

TL outputsThe TL laser system s provide the follow ing

output signals:

After the transm itter and receiver are

enabled, the laser system provides the

inform ation Laser OKif the lum inanceat the receiver is at least 75 % of the

m axim um .

Tw o output signals are generated w hen

the laser beam is interrupted. The

measuring signal static STAoutputsw itches to low level if the lum inance at

the receiver is less than 50 %

(= interrupted light beam ).

D o not use this output as trigger signal.

Fast rotating tools cause spike pulses w ith

extrem ely short pulse tim es that cannot be

evaluated by the PLC or N C.

The measuring signal dynamic DYNoutput provides a 24 V pulse w ith a de ned

duration of 20 m s for every light

This output serves for the trigger signal.
