4 Functions

This chapter describes the functions of the light curtain for adaptation to different applications and operating conditions.

4.1 Beam modes

4.1.1 Parallel

In “parallel”-beam mode (parallel-beam scanning), the light beam of each transmitter LED is detected by the directly opposing receiver LED.

Functions

Figure 4.1: Beam path in “parallel”

4.1.2 Diagonal

In “diagonal” beam mode, the light beam of each transmitter diode is received in succession both by the directly opposing receiver diode as well as by the next receiver diode in the counting direction (i-1) (parallel and diagonal beam path). This increases the resolution in the middle between the transmitter and receiver.

Calculation The number of beams for diagonal-beam scanning n

parallel-beam scanning n

is calculated from the number of beams for

Formula for calculating the number of beams for diagonal-beam scanning

[number] = number of beams for diagonal-beam scanning

[number] = number of beams for parallel-beam scanning

Example: 288 beams in parallel-beam scanning become 575 logical individual beams in diagonal-beam scanning, which must be taken into account during evaluation functions. With a beam spacing of 5 mm, this spacing is reduced to 2.5 mm in the center area.

The “diagonal” beam mode (diagonal-beam scanning) can be activated via the IO-Link interface (see chapter 10) or via the

Sensor Studio

configuration software (see chapter 12).

NOTICE

Minimum distance for diagonal-beam scanning!

 For diagonal-beam scanning, the minimum distance that must be maintained between transmitter and

receiver changes, whereby the values vary depending on beam spacing (see chapter 16).

NOTICE

Teach after changing the beam mode!

 Changing the beam mode changes the number of beams used for the evaluation. Perform a teach

after changing the beam mode (see chapter 8.2).

4.1.3 Crossed-beam

The “crossed-beam” mode (crossed-beam scanning) is available for increasing the resolution for an area of the measurement field. In “crossed-beam” mode, the light beam of each transmitter LED is detected in succession both by the directly opposing receiver LED as well as by the two adjacent receiver LEDs (i+1, i-1).

NOTICE

Minimum distance for crossed-beam scanning!

 For crossed-beam scanning, the minimum distance that must be maintained between transmitter and

receiver changes, whereby the values vary depending on beam spacing (see chapter 16).

Example: 288 beams in parallel-beam scanning become 862 logical beams in crossed-beam scanning. With a beam spacing of 5 mm, this spacing is reduced to 2.5 mm in the center area.

The “crossed-beam” mode (crossed-beam scanning) can be activated via the IO-Link interface (see chapter 10) or via the

Sensor Studio

configuration software (see chapter 12).

4.2 Measurement beam sequence

By default, the counting direction of the beams begins at the sensor connection unit. It can, however, be reconfigured so that counting begins with 1 at the sensor head.

The simplest application case for the inverted beam sequence is vertical mounting with the connection unit at the top, e.g., for height measurement, where beam 1 is to begin at the bottom:

a Receiver connection unit b Optical part

Another variant with two successive light curtains, where the second is rotated by 180° and counting again begins with 1, is illustrated as follows:

a Receiver connection unit b Optical part

For width detection, counting can begin with 1 at either end at the head part of the sensor as shown below:

a Receiver connection unit b Optical part

4.4 Evaluation functions

The states of the individual optical beams (free/interrupted) can be evaluated in the CML 700i and the result read out via various evaluation functions.

The most important evaluation functions are shown in the following figure:

2 Total of not interrupted beams (TNIB) 3 Last interrupted beam (LIB) 4 Last not interrupted beam (LNIB) 5 First not interrupted beam (FNIB) 6 First interrupted beam (FIB)

Figure 4.5: Evaluation functions

Functions

Also included among the evaluation functions are:

• the status of beam areas 1 … 32

• the status of the digital inputs/outputs

For the beam area mappings to an output pin or the status of the digital inputs/outputs, see chapter 4.10.

4.5 Hold function

The setting of the hold times is performed via the respective fieldbus interface (et seq.) or via the

Sensor Studio

The minima and maxima of the following evaluation functions can be temporarily stored for an adjustable period of time via this function:

• First interrupted beam (FIB)

• First not interrupted beam (FNIB)

• Last interrupted beam (LIB)

• Last not interrupted beam (LNIB)

• Total of interrupted beams (TIB)

• Total of not interrupted beams (TNIB)

• Single-beam evaluation (beam-stream): A beam that has been interrupted once is kept at logical 0 in the output bit until the hold time has expired.

Temporary storage simplifies the reading out of the measurement results if the used control cannot transmit the data at the same speed that the light curtain makes the data available.

configuration software (see chapter 12).

4.6 Blanking

If light curtains are installed such that existing frames / cross bars etc. continuously interrupt some beams, these beams must be suppressed.

During blanking, beams that are not to be included in the evaluation are suppressed. The numbering of the beams is not affected, i.e., the suppression of beams does not change the beam numbers.

Functions

Up to four adjacent beam areas can be suppressed.

The beams can be activated or suppressed via the respective fieldbus interface (see chapter 10 et seq.), via the

Sensor Studio

configuration software (see chapter 12) and partially via the oper-

ational controls on the receiver.

The behavior of each blanking area can be adapted to the requirements of the application:

Logical value of a blanking area Meaning in the application

No beams are blanked All beams of the device are included in the evaluation.

Logical value 0 for blanked beams All beams of the blanking area are taken into account

as interrupted beams (logical value 0) in the evaluation.

Logical value 1 for blanked beams All beams of the blanking area are taken into account

as free beams (logical value 1) in the evaluation.

Logical value is the same as the adjacent beam with lower beam number

Logical value is the same as the adjacent beam with higher beam number

All beams of the blanking area behave in the evaluation like the previous beam.

All beams of the blanking area behave in the evaluation like the subsequent beam.

4.8 Smoothing

With the smoothing function, interrupted beams are then only taken into account in the evaluation if the set minimum number of adjacent beams is reached at the same time.

Smoothing can be used, e.g., to suppress interference caused by spot soiling of the lens cover. Smoothing “1” means that every interrupted beam is evaluated.

NOTICE

Configuration values for smoothing!

 Values from 1 to 255 can be entered for smoothing.

Inverted smoothing Inverted smoothing can suppress interference near the edges of objects, since uninterrupted beams are

not evaluated until the set number is reached. With inverted smoothing it is possible to detect, e.g., only successive openings of a certain minimum size

within a web. For an example configuration, see chapter 11.5.

4.9 Cascading/triggering

If the measurement field length of a light curtain is not sufficient for detecting a desired measurement path, multiple light curtains can be connected in series or cascaded. When doing so, it must be ensured that the light curtains do not mutually influence or interfere with one another. This is ensured by activating (triggering) with a time offset.

The following light curtain arrangements are possible in a cascade arrangement:

• Multiple light curtains above one another, e.g., for height monitoring

configuration software (see chapter 12).

NOTICE

 Cascade light curtains for multiple-track transport systems.

 Prevent mutual interference through sequential activation of the light curtains.

If the spatial configuration excludes mutual interference, multiple light curtains can also be activated simultaneously.

4.9.1 External triggering

Trigger input For an exact time assignment, it is possible to start the measurement cycle of a light curtain in a targeted

manner by means of a pulse at the trigger input. In this way, mutual interference can be prevented in applications with multiple light curtains. This trigger signal generated in the control must be wired at all cascaded light curtains.

The individual light curtains are configured so that the respective measurement is started with different delay times to the trigger pulse (see figure 4.12).

4.9.2 Internal triggering

With internal trigger activation, a CML 700i configured as "master light curtain" generates the trigger pulse. This trigger pulse is continuous; this means that no further activation is required from a primary control.

Trigger output The trigger output of the master light curtain makes available the trigger signal necessary for “cascading

via internal trigger”. The trigger output must be wired to the trigger inputs of the slave light curtains (see figure 4.13). This is used to start the measurement in the configured time sequence.

With this function, the quantity of data to be transmitted can be reduced by restricting the imaging accuracy. The minimum resolution of the light curtain is still retained.

Leuze electronic CML 730-PS 32

Page 33

4.10.1 Defining beam area

To read out the beam states block-wise with a 16-bit or 32-bit telegram, the individual beams can be mapped to up to 32 areas independent of the maximum beam number. The individual beam information of grouped beams is linked to a logical bit, i.e., each area is represented as 1 bit.

The number of beams in an area can be freely defined. However, the beams must be adjacent to one another. The start beam and the end beam are to be defined as well as the conditions for switching of the area.

NOTICE

 The hold function (see chapter 4.5) also applies for the block evaluation of beam areas.

4.10.2 Autosplitting

The beams of the device are automatically divided into the selected number of areas of the same size. The states of the areas generated in this way can be read out in the process data by means of the “Area Out - HiWord” and “Area Out - LoWord” parameters.

Procedure:

• Select logic combination of the beams within the areas (logical AND / logical OR)

• Define the number of desired areas (e.g., 16 or 32)

Functions

The autosplitting configuration can be defined via the interface (see chapter 10) or via the

Sensor Studio

configuration software (see chapter 12).

4.10.3 Mapping beam area to switching output

If grouping individual beams or if creating a block, the beam state of any number of adjacent beams (area) can be signaled at a switching output.

The following options are possible here:

• To use a specific, single beam for the evaluation, e.g., as trigger signal for a primary control.

• To group the complete measurement field into one switching area and thereby signal at the switching output whether an object (at any position) is located in the measurement field.

• To configure up to 32 switching areas for a reference check or height monitoring; in many cases, this can make beam-data processing in the primary programmable logic control (PLC) unnecessary.

The switching conditions for the areas can be either AND or OR linked:

Logic function

Group bit (area status) [logic 1/0]

AND 1 If all beams mapped to the area are interrupted

0 If at least one beam is not interrupted in the selected area

OR 1 If at least one beam is interrupted in the selected area

0 If none of the beams mapped to the area are interrupted

Areas may be sequential or overlapping. A maximum of 32 areas are available.

The switching behavior or the conditions for switching a beam area on and off can be defined via the interface (see chapter 10) or via the

Sensor Studio

configuration software (see chapter 12).

For an example configuration, see chapter 11.2.

4.10.4 Teach height area

With the

Teach height area

function, it is possible to teach in up to four height areas, e.g. for height moni-

toring or sorting packets. In many cases, this saves time for programming.

• A maximum of four height areas are available.

• A height area is automatically defined using an object. When teaching a height area, all free beams above or below the object are combined into one height area. Therefore, the object cannot be located in the center of the measurement field length; the first or last beam must be interrupted.

4.12 Interference suppression (filter depth)

To suppress any faulty measurement values that may occur due to interference (ambient light, electromagnetic fields, …), the filter depth of the light curtain can be increased.

“Filter depth” means that an interrupted/free beam is not included in the further data evaluation until the same beam status is recorded for the set number of measurement cycles.

Filter depth “1” = the beam states of each measurement cycle are output.

4.13 Power setting

Functions for specific application scenarios:

• Detecting transparent films The sensitivity of the receiver can be increased so that the light curtain detects extremely thin transparent films in the measurement range. Configuration: see chapter 8.4 "Setting the function reserve"andsee chapter 11.7 "Example configuration – Detecting transparent films"

• Reliable beam penetration through opaque films The transmitter output power can be increased to such an extent that the light curtain can penetrate opaque, only semi-transparent objects.

4.14 Validation output

The light curtain can signal measurement readiness to the control via a digital output. The light curtain does not deliver any stable measurement values e.g. during a teach event (teach-in).

To debounce the validation signal, it is recommended to configure a waiting time of 100 ms in the control.

After the device has been switched on, measurement readiness is NOT signaled when triggering is activated and the trigger-input signal is missing.

In the menu of the receiver control panel, configure an IO pin as a validation output.

6.1 Mounting the light curtain

NOTICE

No reflective surfaces, no mutual interference!

 Avoid reflective surfaces near the light curtains.

Objects may otherwise not be precisely detected due to halation.

 Ensure sufficient distance, suitable positioning or partitioning.

Optical sensors (e.g., other light curtains, photoelectric sensors, etc.) must not interfere with one another.

 Avoid interference from outside light (e.g., from flash lamps, direct sunlight) on the receiver.

Mount the transmitter and receiver as follows:

 Select the fastening type for transmitter and receiver.

- Fastening via the T-groove on one side of the standard profile (see chapter 6.3).

- Fastening via the rotating bracket on the ends of the profile (see chapter 6.4).

- Fastening via the swiveling mounting brackets or parallel brackets (see chapter 6.5).

 Have a suitable tool at hand and mount the light curtain in accordance with the notices regarding the

mounting locations.

 Mount the transmitter and receiver at the same height or with the same housing reference edge, free of

tension and with the base in full contact with the mounting surface.

Mounting and installation

NOTICE

Must be observed!  For horizontally mounted measuring light curtains with lengths of more than 2,000 mm, use an addi-

tional mounting bracket in the middle of the light curtain.

 The optical surfaces of transmitter and receiver must be parallel to and opposite one another.

 The transmitter and receiver connections must point in the same direction.

 Secure transmitter and receiver against turning or sliding.

Mounting and installation

To achieve the maximum operating range limit, transmitter and receiver must be aligned with one another as accurately as possible.

After mounting, you can electrically connect (see chapter 7) and start up (see chapter 8) the light curtain.

6.2 Definition of directions of movement

The following terms for alignment movements of the light curtain around one of its individual beams are used:

a Sliding: movement along the longitudinal axis b Turning: movement around the longitudinal axis c Tilting: lateral turning movement diagonal to the lens cover d Pitching: lateral turning movement in the direction of the lens cover

Figure 6.2: Directions of movement during alignment of the light curtain

Leuze electronic CML 730-PS 47

6.3 Fastening via sliding blocks

By default, transmitter and receiver are delivered with two sliding blocks (three sliding blocks for measurement field lengths of more than 2,000 mm) each in the side groove (see chapter 17).

 Fasten transmitter and receiver to the machine or system via the lateral T-groove with M6 screws.

Sliding in the direction of the groove is possible, but turning, tilting and pitching is not.

Mounting and installation

Figure 6.3: Mounting via sliding blocks

6.4 Fastening via swivel mount

When mounting with the BT-2R1 swivel mount (See table 17.5), sold separately, the light curtain can be aligned as follows:

• Sliding through the vertical threaded holes in the wall plate of the swivel mount

• Turning by 360° around the longitudinal axis by fixing on the screw-on cone

• Tilting around main axis

• Pitching through horizontal threaded holes in the wall mounting

The wall mounting through threaded holes makes it possible to lift the mounting bracket after the screws have been loosened over the connection cap. Therefore, the mounting brackets do not need to be removed from the wall when exchanging the device. Loosening the screws is sufficient.

Figure 6.4: Mounting via swivel mount

Mounting and installation

One-sided mounting on the machine table The sensor can be mounted directly on the machine table via an M5 screw on the blind hole in the end

cap. On the other end, a BT-2R1 swivel mount can be used, for example, so that turning movements for alignment are possible despite the fact that the sensor is mounted on one side.

NOTICE

Avoid reflection bypasses at the machine table!

 Make sure that reflections on the machine table and in the vicinity are prevented reliably.

7 Electrical connection

7.1 Shielding and line lengths

The light curtains are equipped with modern electronics developed for industrial applications. In industrial environments, a number of sources of interference may affect the light curtains.

In the following, information is provided on the EMC-compliant wiring of the light curtains and the other components in the switch cabinet.

7.1.1 Shielding

NOTICE

General shielding information!

 Avoid interference emissions when using power components (frequency inverters, …).

The necessary specifications under which the power component satisfies its CE Declaration of Conformity can be found in the technical descriptions of the power components.

In practice, the following measures have proven effective:

Properly ground the total system.

Screw mains filter, frequency inverter, etc., flat to a galvanized mounting plate (thickness 3 mm) in the switch cabinet.

Keep cable between mains filter and inverter as short as possible and twist cables.

Shield both ends of the motor cable.

 Carefully ground all parts of the machine and of the switch cabinet using copper strips, ground rails or

grounding cables with large cross section.

 Keep the length of the shieldless end of the cable as short as possible.

 Guide the shielding untwisted to a terminal (no “RF braid”).

tain cables as possible (distance > 30 cm).

 Avoid laying power and light curtain cables parallel to one another.

 Cable crossings should be laid as perpendicular as possible.

NOTICE

Lay cables close to grounded metal surfaces!

 Lay the cables on grounded metal surfaces

This measure reduces interference coupling in the cables.

NOTICE

 Carefully ground all parts of the machine.

Leakage currents arise from incorrectly implemented equipotential bonding.

You can measure leakage currents with a clip-on ammeter.

NOTICE

Star-shaped cable connections!

 Ensure that the devices are connected in a star-shaped arrangement.

You thereby avoid mutual influences from various loads.

This prevents cable loops.

Grounding the light curtain housings

 Connect the transmitter housing and receiver housing of the light curtain to the protective conductor on

the FE machine star point via the PE screw on the grounding slot nut (see figure 7.1).

The cable should have an impedance as low as possible for high-frequency signals, i.e., be as short as possible and have a large cross-sectional area (grounding strip, …).

 Use a lock washer and check the penetration of the anodized layer.

 Check the small Allen screw to ensure a secure connection between the grounding slot nut and housing.

The Allen screw is correctly tightened upon delivery from the factory.

If you have changed the position of the grounding slot nut or the PE screw, tighten the small Allen screw.

8 Starting up the device - Basic configuration

The basic configuration includes the alignment of transmitter and receiver and the basic configuration steps via the receiver control panel.

The following optional basic functions for operation and configuration are available at the receiver control panel (see chapter 8.5 "Extended configurations on the receiver control panel menu"):

• Define digital inputs/outputs

• Inversion of the switching behavior

• Defining the filter depth

• Defining the display properties

• Changing the language

• Product information

• Resetting to factory settings

8.1 Aligning transmitter and receiver

NOTICE

Alignment during commissioning!

 The alignment performed during commissioning should only be performed by qualified personnel.

 Observe the data sheets and mounting instructions of the individual components.

Starting up the device - Basic configuration

Prerequisites:

• The light curtain has been mounted (see chapter 6) and connected (see chapter 7) correctly.

 Switch on the light curtain.

NOTICE

The next configuration step is teaching the environmental conditions (teach).

8.2 Teaching the environmental conditions

During teaching, the system checks whether the signals of all beams are within a certain corridor. This means that a teach event generally regulates all beams to the preset function reserve (or sensitivity)

for the current operating range. This ensures that all beams exhibit an identical switching behavior.

NOTICE

Conditions for performing a teach!

 When teaching without preconfigured blanking areas, the light path must always be completely free.

A teaching error will otherwise occur.

 In this case, remove the obstacles and repeat the teach.

 If the light path is partially interrupted by structural elements, the permanently interrupted beams can

be suppressed by means of blanking ( this case.

 To automatically suppress the affected beams during teaching, configure the number of blanking

areas via the configuration software

The configuration can be performed via the IO-Link interface (see chapter ) or via the

Sensor Studio

configuration software (see chapter 12).

(see chapter 12).

You can choose whether the teach values are to be stored permanently or only temporarily (while the operating voltage is applied). The configuration ex works is for permanent (non-volatile) stor- age.

A teach event can be performed both directly from process mode as well as from alignment mode.

NOTICE

Execute teach after changing the beam mode!

 Always perform a teach after changing the beam mode (parallel-/diagonal-/crossed-beam scanning)

as well.

Prerequisites:

• The light curtain must be correctly aligned (see chapter 8.1).

 You can use one of the following teach types:

Teach via receiver control panel (see chapter 8.2.1).

Teach via teach input (see chapter 8.2.2).

Teach via IO-Link interface (IO-Link, see chapter ).

configuration software (see chapter 12).

During a blanking teach or auto blanking, an “additional distance” is always added to the beams detected as interrupted. Safer operation is thereby achieved, e.g., in the case of vibrating guides, etc., in the “blanked” area.

Optimization of the blanked beams is to be performed via a software interface configuration.

A maximum of four adjacent areas of suppressed beams (blanking areas) can be configured.

The next configuration step is to check the alignment.

8.3 Check alignment

Prerequisites:

• The light curtain must first be correctly aligned and a teach must be performed.

 Check whether the green LEDs on the receiver control panel and transmitter illuminate continuously.  Use the bar graph indicator to check whether the light curtain is optimally aligned, i.e., whether the max-

imum is reached for both the first beam (FB) and the last beam (LB) in the bar graph indicator.

 Use the bar graph indicator to check the optimum alignment of the light curtain if you have corrected an

error that occurred.

• Perform extended configurations on the receiver control panel if necessary (see chapter 8.5)

• Start up CML 700i light curtains with analog output (see chapter 9)

• Start up CML 700i light curtains with IO-Link interface (see chapter 10)

8.4 Setting the function reserve

The function reserve can be set to the following levels:

• High: High function reserve for stable operation, low sensitivity

• Medium: Medium function reserve

• Low: Low function reserve, high sensitivity

• Transparent: Detection of transparent objects

• Target function reserve: Automatic adjustment of the transmitter power and the receiving sensitivity

• Tx/Rx power: Manual, separate adjustment of the transmitter power and the receiving sensitivity

The function reserve can be set via the receiver control panel, via the IO-Link interface (see chapter 10) or via the

Sensor Studio

The sensitivity levels (e.g., high function reserve for stable operation, medium function reserve and low function reserve) are configured ex works with “high function reserve for stable operation”. The “low function reserve” configuration enables the detection of partially transparent objects.

• Select maximum sensitivity for high beam penetration capacity. At maximum sensitivity, the light curtain may still be able to detect objects if a transparent medium allows almost no energy to pass through.

• If the receiver is set to an extremely high sensitivity, the light curtain switches even with extremely small objects which cause only very slight damping. In this case, the light curtain becomes e.g. more sensitive to dust if a low function reserve is set.

• Higher sensitivity of the receiver also means higher measurement value noise. The measurement value noise alone may cause pseudo switching of the light curtain if the hysteresis is set too low.

 For the transmitting power (Tx), enter a value between 3% (lowest transmitting power) and 100% (high-

9.3 Behavior of the analog output

The output logic of the CML 700i returns the output signals to the programmable logic control (PLC). On interface X1, three pins can be assigned as output for the analog control of the PLC process interface.

The selected beam area (start beam/end beam) is mapped to the analog output of the CML 700i. The conversion is by means of a 12-bit D/A converter, whereby the 12-bit value (4096) is divided by the selected number of beams. The resulting values, mapped to the respective, configured analog values, yield the characteristic curve. If there are only a few beams, this results in an erratic characteristic curve.

The beams used for the measurement can be freely defined via the receiver control panel. It is also possible to specify that only a part of the beam area be used for the measurement.

NOTICE

A maximum of 256 beams can be processed as a bit!

 The IO-Link specification only permits 32 bytes as process data; i.e., up to 256 beams can each be

processed and transmitted as a bit.

 Through the limitation of the process data length, the beams, depending on the resolution, can only

be processed and transmitted up to a certain measurement field length as a bit.
