1.3 Intended use

Flexible Manufacturing Systems in the sheet processing industry require reliable Double Sheet Control systems in order to protect presses and other sheet processing machines against damage caused by feeding multiple sheets.

The Double Sheet Detector R1000 L20 was specifically developed for this technical environment. The reliable function of the Double Sheet Detector depends therefore most importantly on the selection of the correct sensors and the mounting of the sensors.

1.4 General hints for process reliability

The process security of the system is influenced by the following factors:

• Stability of the measuring values

• Setting of under-gauge threshold and over-gauge threshold

• Evaluation of the status signals Stable measuring conditions will result in stable measuring results. Varying measuring results are

undesirable, because in such cases the user is inclined to decrease the under-gauge threshold LOW and to increase the over-gauge threshold UP. On doing so, the user puts up with the drastically increasing risk of not detecting a double sheet.

The following external factors decisively influence the stability of measuring results and need to be considered for operation of a double sheet detector:

• Optical characteristics of the material

• Tolerance in material thickness

• Contamination of the material

• Geometric conditions at the place of measurement (Stability of the sensor gaps)

• Contamination of the sensors (dirt, oil …) From this some simple rules can be derived, which enable a high process security when abided by:

• Every different sheet (Thickness, material and contour) is measured with separate measuring program.

• Adjust the switching thresholds as tight as possible!

• Keep the sensor gap constant!

• Make use of the air connection to keep the sensors clean!

Furthermore it is necessary that the machine control:

• checks all status signals of the L20,

• checks the 0-sheet signal.

While measuring, only the 1-sheet signal may occur. If 0-sheet or 2-sheet occurs, the measured sheet may not be transported on. In such cases, the sheet will usually be removed.

• The machine controls needs to evaluate all status signals !

Checking-up through the 0-sheet signal is to assure that a sheet really is between the sensors during measuring. If 0-sheet occurs while measuring, the measurement is not correct. For example, a defective sensor holder might change the sensor gap. Monitoring the sheet thickness would then only be seemingly performed.

In case of double sheet severe consequences could then result.

3.1 Measurement principle

The function of the Double Sheet Detector is based on the principle of laser triangulation. The sensor system consists of two sensors which measure the distance.

If the total distance is known it is possible to calculate the sheet thickness.

x-(A+B)

D= A

Fig. 2: Measurement principle

3.1.1 Planning information for mechanics

The total distance Ax of both sensors from each other has a great influence on the measurement precision.

Important An appropriate stable and rigid mechanism is required.

Possible determining factors are also:

1. Thermal expansion

2. Vibrations

3. Impacts, press travel

4. Force and torque effects

These factors must be considered sufficiently when dimensioning the mechanics and the sensor mounting. Permissible deviations Delta Ax must be smaller than 1/6 of the smallest thickness D to be measured.

Example: For a reliable monitoring of sheets for double sheet detection with a nominal thickness of

0.3 mm, the permissible deviation Delta Ax is:

+/- 0.3 mm / 6 = +/- 0.05 mm.

Manual

Double Sheet Control System R1000 series L20

B0063191 / 1.3

Considering the typical measurement inaccuracy of +/- 0.05mm of the LAS40 sensors itself, therefore a total error of +/- 0.1mm may occur.

Sheet thickness 0.3 mm: -> measuring value between 0.2 mm and 0.4 mm Sheet thickness 0.6 mm: -> measuring value between 0.5mm and 0.7mm

For safe operation, the upper limit must be set to 0.45mm (= 150% of the nominal thickness) and the lower limit to 0.15 mm (= 50% of the nominal thickness).

If the limits 150% respectively 50% are not sufficient, a calibration must be performed.

When dimensioning the mechanics and the sensor mounting, the Delta values Ax (permissible deviation of the base distance due to thermal expansion, vibrations, impacts, press travel) must be considered: According to the smallest sheet thickness, following deviations must be observed:

3.1.2 Planning information for calibration

LAS200

If the values Delta Ax cannot be achieved, a regular calibration may be helpful. Ideally, a gauge block is provided in mechanics. This can be done via a pneumatic cylinder and is

then automated via PLC control.

3.1.3 Planning information for air blow-off

The operation of the system in ambience containing oils, as it occurs at press lines in the immediate vicinity of oiling is generally possible if following is respected:

1. The air blow-off of the sensors is used.

2. The system test of the L20-3-XX-S (only LAASxx+ sensors) is accessed cyclical via PLC.

3. The sensors are well accessible for cleaning.

Normally the air blow-off is sufficient to allow reliable operation in vicinity of oiling. However, failure of air blow-off, can cause serious contamination. This requires the cleaning of the sensor optics. Therefore, in any case, the safe access to the sensors must be ensured.

3.2 Control unit

The L20 is based on the product platform R1000. Major features of the control unit:

• Programmable for 255 different sheet thicknesses / types of sheets

• Fieldbus interface for the control, operation and data exchange with the PLC

• Calibration of the measuring point with a calibration sheet

• Digital display of sheet thickness and operating parameters

3.2.2 Parameters of the control unit

The L20 provides for extensive configuration. So, different customer requirements can be served. Configuration is performed by setting system parameters, adjust parameters and program parameters. System parameters are set only once during commissioning, and will then remain unchanged. Program parameters contain items which are material and job depending, and enable individual adaptation to the measuring task. The adjustment parameters contain the adjustment of the measuring point.

The parameters are explained in depth in the chapter 7.3 „Operation“.

Pay special attention to the program parameters „low“, „up“ and „moving average above xx ms“

The switching thresholds of the status signals depend on the settings of „low“ and „up“. The measuring signal is fed to a window comparator. The signal “0-sheet“ is generated when the measuring signal falls below the lower switching threshold “ low”. The lower switching threshold “low” can be set from 1...100%. The signal “2-sheet“ is generated when the upper switching threshold is exceeded. The upper switching threshold “up” can be set from 100...180%. If the measuring value is within both limits, the signal “1-sheet“ is generated.

The preset values (up=120% resp. low=80%) should only be changed under the following aspects:

1. Target: Increasing the process reliability

Prerequisite: Very stable measurement values Implementation: Restrict the 1-sheet area. This is done by decreasing the “low” value

and/or increasing the “up” value.

2. Target: Keep the system function alive despite fluctuating measuring values (e.g. mechanical problems) Prerequisite: Exceptional situation till correction of the problem. A reduction of the process reliability is hereby taken into account by the operator. Implementation: Expand the 1-sheet area temporarily.

„moving average above xx ms“

4 Mounting

The mounting of the Double Sheet Detector R1000 L20 determines the measurement accuracy and the reliability of operation. The system was designed for operating in rough industrial environments. However, the following mounting instructions should be observed in order to minimize mechanical, thermal, and electromagnetic influences on the operation.

4.1 General mounting instructions

The enclosure for wall mounting meets IP65 and is designed for mounting the enclosure close to the sensor location. By using short sensor cables, the influence of interference on data transmission is reduced.

The control unit should be installed in locations where no vibration exists and no additional heat is transferred into the system (even better reduce the heat in the control unit). In addition the control unit should be installed in such a fashion that it can be easily opened for service purposes. During the operation the control unit and the sensors should be under visual control of the operating personnel.

Attention Strong vibrations and additional heat can damage the control unit.

4.3 Mounting of sensors

The sensors must be installed opposite each other in alignment. If circumstances require it, the mechanical mounting angles can be rotated or swapped.

To ensure an accurate measurement, ensure that the laser axes of the two sensors are identical (on each other). For this purpose Roland Electronic provides the bracket SHLAS40H, which allows easy alignment (not shown). The sensors provided within the sensor system LAAS40 have already been aligned using the bracket SHLAS40H.

For an initial installation, they can be mounted directly. If the sensors are adapted or exchanged, they must be aligned before mounting.

Mounting

The provided bracket SHLAS40H is not shown above.

Fig. 8: Dimensions of the sensors

All dimensions in mm.

To prevent contamination of the sensors it is necessary to provide a continuous air blow-off. See chapter 4.3.8 "Air blow-off for laser sensors".

Attention In general baffles must be mounted in order to prevent damage to the sensors at incoming coil / sheet.

4.3.1 Procedure at mounting

The alignment-bracket must be removed only at the end of the mounting process!

1. Screw the sensors loosely on the angles.

2. Screw the angles to the system, but do not tighten the screws. Make sure that no mechanical tension occurs between the sensor enclosures.

3. Tighten all screws. Take care that no tensions persist between the parts.

4. Finally remove the alignment-bracket.

5. At L20-3-XX-S with LAAS40+: Verify sensor alignment with adjust parameter 4, “alignment”.

Attention After mounting a measuring point calibration should be performed to the L20. See also chapter 8.4 "Measuring point calibration".

4.3.2 Alignment of the sensors at remounting, exchange or change

1. For alignment of the sensors place the sensors one to each other with the mounting side on a

adjusting plate or an equally smooth surface.

2. Lay a gauge block or equivalent with 40 mm between the sensors.

3. Screw the adjustment-bracket tight. The screws may be screwed in this case depending on the mounting situation from both sides in order to be easily removed after the alignment. Thereby make sure that the sensors lay plane to the plate and fit firmly against the gauge block.

4. Fasten the sensor pair as described previously.

Attention After mounting a measuring point, a calibration should be performed to L20. See also chapter 8.4 "measuring point calibration".

4.3.3 Control of the laser beam axis

After mounting or adjusting a sensor it might be necessary to control the axis of the laser beam. In the program switch the „sensor alignment help“ on, see chapter 7.4.3 substructure „alignment parameters“ (details in chapter 7.8)

To check hold a non-reflective piece of paper at various points in the beam. The sensors will flash alternately. The laser beam is visible through the paper, so that a properly aligned system should have no offset between the two points on the paper. At a larger displacement or angular deviation of the laser beam, an inclined position of the sheet can lead to variations in measurements. At an offset of several millimetres, the sensors should be realigned. At usage of LAAS40+, the alignment can be verified with adjust parameter 4, “alignment”.

Warning – Laser radiation!

Eye hazard from laser radiation. Do not stare into the laser beam.

4.3.4 Position and location of the sheet between the sensors

Ideally the sheet should be transferred through the middle of the sensor gap. This guarantees reliable and accurate results of the measurement.

The sheet must be guided perpendicular to the laser axis; otherwise it comes due to geometry to measurement errors.

Avoid mechanical damage due to incoming material and take appropriate measures such as baffles.

Mounting

Fig. 9: Position of the sheet between the sensors

4.3.5 Sensor gaps

The gap between the sensors is derived from the sensor name in mm. The sensor LAAS40 has a gap of the sensors of 40 mm with a tolerance of ± 2.5 mm.

In the final mounted and aligned state the start-up at the L20 must be done by performing the "Measuring channel calibration".

This is done with a calibration sheet having a defined thickness in order to define the total distance between the sensors.

This total distance serves as a reference for the thickness measurement and must remain constant during operation.

This requires a correspondingly stable and rigid mechanism, see chapter 3.1.1 "Planning Information for Mechanics".

4.3.6 Electromagnetic interference

Electromagnetic interference can affect the measurement accuracy of sensors. Therefore it is not allowed to mount the sensors in direct proximity of equipment which emits electromagnetic interference.

The sensor cables should not be laid adjacent to conductions having a large disturbance potential, e.g. power cables. This applies especially to longer cable lengths.

4.3.7 Compliance with the transport direction at sensor mounting



Mounting of the sensors regarding to the

following illustration will ensure reliable double

sheet detection.

Fig. 10: Direction of transport



When mounting in "longitudinal direction", the measuring must be performed only dynamically (sheet is not allowed to stand still between the sensors).

4.3.1 Air blow-off for laser sensors

To prevent contamination of the sensors it is necessary to provide a continuous air blow-off. This is done by connecting an air hose with 8 mm outer diameter.

A permanent air blow-off of approx. 0.5 bar pressure is recommended, alternatively 5 bar cyclic cleaning.

Possible contamination Air blow-off

Oil, oil mist, water Continuous, approx. 0.5 bar

Rough tinder Continuous, approx. 5 bar

Dust, fine tinder Cyclic, approx. 5 bar

Note Air loss causes contamination!

To disconnect the hose use an 8 mm or 9 mm open-ended wrench as shown in Fig. 6, right.

 For the supplied purging air there are requirements regarding purity and freedom from oil.  The requirements are:  Operating medium: compressed air according to ISO 8573-1: 2010 [-: 9: -] inert gases (see

table)

 Air purity class at the output: compressed air in accordance with ISO 8573-1: 2010 [1: 7: 2] inert

gases (see table)

5 Electrical installation

5.1 General instructions

The sensor cables should be kept as short as possible in order to minimize the influence of electromagnetic noise. Cable shields must be connected according to the connection diagrams only and should not have any additional connections.

Attention Damaged cable installations may result in additional electrical

connections. This can disturb the measured values.

5.1.1 Mounting instruction for M12 connectors with key way

These connectors have a positioning nose at the plug and a positioning slot at the receptacle. These items are designed to prevent incorrect connecting positions.

For this reason if plug and receptacle are connected together then these positioning features should fit to each other.

Only then it is possible to connect plug and receptacle without force and with proper pin configuration.

A Positioning slot at female connector

B Positioning nose at male connector

C Threaded arresting ring

D Connector assembly ring.

Never turn this ring when arresting the plug with the arresting ring C.

Electrical installation

Fig. 12: Positioning facility and arresting ring

When the connection is established correctly as described, plug and socket can be arrested with the arresting ring.

Attention Turn only the threaded arresting ring C !

If the whole plug becomes turned, the locking facility and the contact pins will break and the connector will become useless.

Attention Under any circumstances it is not allowed to use any part of a

plug connection as a holder for the installation of the counterpart.

Double Sheet Control System R1000 series L20

Communication with the PLC B0063191 / 1.3

with integrated fieldbus interface

6.2 Data transmission communication

The L20 uses an IN/OUT configuration for the cyclical data exchange with the master. This means that for each transmission direction a parameter channel with 8 Bytes as well as a process channel with 16 Bytes is used.

The R100 is controlled via the process channel and via the parameter channel all system and application data is available.

The following table shows the layout of the communication facility:

Inputs (PLC  L20) Outputs (L20  PLC)

Range (only L20-3-XX-S)

Explanation of summary output 0-sheet, 1-sheet and 2-sheet:

If the unit is operated in the sequencer mode (program with more sensors e.g. 1+2+3), the measurement result is formed as summary output. Only the active sensors are included.

2-sheet is issued if at least one sensor detects 2-sheet.

1-sheet is issued if all sensors detect 1-sheet.

0-sheet is issued if no 2-sheet is detected but at least one sensor detects 0-sheet.

If the results of individual sensors are required, then interrogate bytes 12-23.

If a fault occurs at the equipment an operator intervention is required e.g. memory error, low or missing voltage.

2),3), 4)

Footnotes see next chart “Byte 12 to 14”

At R1000 systems with multiple measuring points, these outputs are issued as "summary output" for all measuring points;

as this equipment has only one measuring point available, the result of the measuring point 1 will be outputted.

This function is implemented only in L20-3-XX-S (L20-XX-S in preparation).

6.3.2 External single measurement via process channel

Communication with the PLC

Fig. 16: Timing diagram for start single measurement via process channel

In case of “Function fault“, “Function result“ is not necessarily set.

The measuring time depends on the time set for averaging.

Start “Measurement start“

wait until

“Function fault“ or “Function result“

In case of “Function fault“ then:

- Pause 100 ms

- Unset “Measurement start”

- Reset “Function fault“

In case of “Function result" then:

- Analyse

- Unset “Measurement start”

Explanation:

• If a fault occurs when initiating the function (for instance a previous function is still active) then only the “Function fault“ is displayed. The “Function result“ will not be displayed. The other outputs remain in their current status.

• If the fault occurs during execution, the “Function fault“ is displayed. The “Function result“ will not be displayed (if the fault is connected to the function). The outputs remain in their current status.

• If the fault occurs after the result, e.g. by a faulty operation then this has no influence on the “Function result“.

• If the “Measurement start“ cycle is shorter than the duration of the function then the “Function result“ will not be displayed. However, the function is nevertheless executed! For safety reasons the control should not be executed in this style!

• If the “Measurement start“ cycle is longer than the duration of the function then the “Function result“ will be displayed as shown in the timing diagram.

Note Uncritical faults can be deleted via the process channel with the

“Reset function fault“ command.

Note The measured timing periods were determined with12 Mbit/s Profibus.

These timing periods can vary with different transmission rates and bus systems. The cycle time of the PLC has not been taken into account.

6.4 Parameter channel

The parameter channel is designed to exchange systems and parameter data of the R1000 with the master. Primary purpose is the central data backup on the master. In addition, certain measurement and operating parameters can be extracted from the R1000 and analyzed by the master.

Note When re-transmitting the system and program parameters, the system parameters must be re-transmitted first!

Note The configuration of the data format has to be compatible with the PLC for consistent data transmission!

The data transmission via the parameter channel must be initiated with the service “Open parameter channel“. The end of data transmission mission via the parameter channel must be completed with the service “Close parameter channel“.

If the parameter channel is open then it is not possible to issue control commands via the process channel or via inputs on the keyboard.

Data access control (management)

The management byte (BIN0) is used by the master to select the service (for example writing or reading) and to confirm the access. The R1000 confirms via the management byte (BOUT0) the execution of the command. The execution may need up to 100 ms. If an access is not allowed and therefore, the service cannot be executed, then the R1000 declares this action as a collision.

Services have to be executed only by the master. The R1000 cannot initiate a data transmission as slave.

Program index

Program index enables the access to one of the 255 programs. The access to the systems parameters is made via the program index 255.

Parameter index

The parameter index enables the access to the parameters of each program.

Application data bytes The application data bytes 0 to 3 contain the data which must be transmitted. Checksum

The checksum is formed of the bytes 1 – 6. The bytes BIN1 to BIN6 respectively BOUT1 to BOUT6 are summed. The least significant is the respective checksum.

6.4.2 Service "Open parameter channel"

The service open parameter channel is initiated by the master with the selection of the service. The content of the index bytes BIN1, BIN2 and the application data bytes 0 to 3 are not relevant. The checksum of bytes 1 to 6 is calculated and inserted into byte 7. To initiate the service the master changes the handshake bit. To avoid data fault the following sequence is mandatory:

1. Service selection, program index, parameter index

2. Switch handshake

In addition a consistent data transmission from the master is necessary.

Note For the service “Open parameter channel“ the index bytes BIN1, BIN2

and the application data bytes BIN3... BIN6 are not relevant.

The R1000 checks the data with the checksum and mirrors the application data, the service selection and the index selection into BOUT1, BOUT2. The R1000 sets the handshake bit in BOUT 0.0 only in the last step and signals thereby that the data is valid. This sequence is observed by the R1000 in order to avoid data faults.

The slave ensures a consistent data transmission.

Note If reading cannot be executed the collision bit is set. The fault number is transmitted instead of application data bit , see section “6.4.8. Reset faulty access“. The collision bit can be deleted by one of the following services: “Close parameter channel”, “Empty service” or “Reset parameter channel”.

6.4.3 Service "Close parameter channel"

This service is initiated by the master by selecting the service. The content of the index bytes BIN1, BIN2 and the application data bytes 0 to 3 is not relevant. The checksum of bytes 1 to 6 is calculated and inserted into byte 7. To initiate the service the master changes the handshake bit. To avoid data fault the following sequence is mandatory:

1. Service selection, program index, parameter index

2. Switch handshake

In addition consistent data transmission from master is necessary.

Note For the service “Open parameter channel“ the index bytes BIN1,

The R1000 checks the data with the checksum and mirrors the application data bytes, the service selection and the index selection in BOUT1 and BOUT2. The R1000 sets the handshake bit in output BOUT0.0 only in the last step and signals thereby that the data is valid. This sequence is observed by the R1000 in order to avoid data faults.

The slave ensures a consistent data transmission.

Note If the checksum is correct then the closing of the parameter channel is always executed. A set collision bit is thereby deleted.

BIN2 and the application data bytes BIN3... BIN6 are irrelevant.

6.4.4 Service "Read parameters"

The master initiates the service “Read parameter“ by selecting the service, and index bytes BIN1 and BIN2. The content of the application data bytes 0 to 3 is not relevant. The checksum of byte 1 to 6 is calculated and inserted into byte 7. To initiate the service the master changes the handshake bit. In order to avoid data faults the following sequence is mandatory:

1. Service selection, program index, parameter index

2. Switch handshake In addition consistent data transmission from master is necessary.

Note The application data bytes BIN3 - BIN6 of the service “Read

The R1000 checks the data with the checksum and makes the content of the respective parameters available in the application data bytes of parameter channel BOUT3... BOUT6. In addition the R1000 mirrors the service “Read parameter“ and the index adjustment in BOUT1, BOUT2. Only in the last step the R1000 sets the handshake bit intoBOUT0.0 and indicates thereby that the data is valid. This sequence is observed by the R1000 in order to avoid data faults.

The slave should ensure a consistent data transmission.

Note A collision bit is et if reading cannot be executed. Instead of application data the default number is transmitted, see “6.4.8 Reset faulty access“.

parameter“ are not relevant.

Communication with the PLC

6.4.5 Service "Write parameters"

Initiate the master with the setting of the service selection, the index bytes BIN1 and BIN2. The content of the application data bytes 0 to 3 is also stored. The checksum of byte 1 to 6 is calculated and inserted in byte 7. To initiate the service the master changes the handshake bit. In order to avoid data faults the following sequence is mandatory:

1. Service selection, program index, parameter index, application data byte 0 to 3

2. Switch handshake In addition consistent data communication from the master is necessary. The R1000 checks the data with the checksum and transfers the content of the application data

bytes of the parameter channel BIN3…BIN6 into its own parameter memory. Afterwards the R1000 mirrors the index adjustment in BOUT1, BOUT2 and the application data in BOUT3…BOUT6. Only in the last step inserts the R1000 the handshake bit in BOUT0.0 and indicates thereby that the data has been completely accepted. The same sequence applies here also, in order to avoid data faults.

The slave ensures a consistent data transmission.

Note If writing cannot be executed, the collision bit is et. In place of the application data a fault number is transmitted, see section “6.4.8 Reset faulty access“.

6.4.6 Service "Empty service"

The master initiates the service “Empty service“ with the setting of the service selection. The content of the index bytes BIN1, BIN2 and the application data bytes 0 to 3 are not relevant. The checksum of byte 1 through 6 is calculated and inserted in byte 7. To initiate the service the master switches the handshake bit. In order to avoid data faults the following sequence is mandatory:

1. Service selection, program index, parameter index, application data byte 0 to 3

2. Switch handshake In addition consistent data communication from the master is necessary. The R1000 checks the data with the checksum and mirrors the index adjustment in BOUT1,

BOUT2 and the application data in BOUT3…BOUT6. A possibly set collision bit is set back. Only in the last step inserts the R1000 the handshake bit in BOUT0.0 and indicates thereby that the data has been completely accepted. The same sequence applies here also, in order to avoid data faults.

The slave ensures a consistent data transmission.

Note If the service “Empty service“ cannot be executed, the collision bit is set (remains set). In place of the application data a fault code is transmitted, see section “6.4.8 Reset faulty access“.

6.4.7 Service "Reset parameter channel"

The service “Rest parameter channel“ initiates the master by transferring a zero string. The service was added for safety reasons during the start-up of the system or in case a fault occurs in the bus.

The R1000 closes the parameters channel and mirrors "parameters channel closed" (38 00 00 00 00 00 00 00 Hex). The handshake bit remains set to 0. The collision bit is also set to 0.

Note If the fieldbus is off-line the service “Reset parameter channel“ is automatically executed.

6.4.8 Reset faulty access

For the following reasons a service cannot be executed:

• The current operating conditions do not allow the execution of the selected service.

• The collision bit in the management byte has not been reset.

• The index register address invalid parameters.

• The service cannot be applied to this parameter.

• The application data contains inadmissible values.

• The service is unknown. The reasons above can prevent the service execution during reading or writing. The R1000

indicates this problem by the collision bit. In order to prevent an additional uncontrolled access procedure, the R1000 expects the reset of the called service by the master. In addition the master executes an “Empty service“ with the confirmation of a handshake. After receipt of this empty order, the R1000 puts the collision bit back and confirms the service with a handshake. Thus the fault condition can be reset and the R1000 is available for further orders.

Note If necessary the collision bit can be reset by the service “Close

6.5 External I/O control

The system is normally controlled via the process channel. The exception is the signal "Measurement start", which, for fast procedures, can also be controlled via the Optocoupler inputs (IN). A mixed operation is also possible. The control cannot, however, be made simultaneously by both signal sources.

The “Measurement start“ signals can be initiated via the process channel or the opto couplers. The “Measurement start“ signals can be initiated via the process channel or the opto couplers. Simultaneous initiation leads to an error message.

IN0 Measurement start input 1 Optocoupler input 1, 24 V active

IN1 Measurement start input 2 Optocoupler input 2 24 V active

IN2 Measurement start input 3 Optocoupler input 3 24 V active

The “Measurement start“ inputs are linked in different combinations via AND. The following configuration can be selected in the control unit:

• IN0

• IN0 and IN1

• IN0 and IN1 and IN2

In addition the signals “0-, 1-, 2-sheet”, “ENABLE” and “Warning” are available for further processing via Optocoupler (OUT).

If the signal BOUT “Ready“ is reset, then a fault has occurred, which requires a user intervention at the control unit. Possible causes: memory faults, missing or too low voltages.

Note The timing diagrams in the sections “6.5.3“ and “6.5.4“ do not contain an

explicit chart of the signal “ENABLE“.

6.5.2 Signal "Warning"

The “Warning“ signal is an additional output signal with fixed evaluation thresholds. The signal becomes activated if the measurement result is below 80% or above 120% of the preset

nominal value.

Note The signal will also be activated if measurements without a sheet

(measurement value below 80%) are performed.

Fig. 60: Display of the sensor alignment aid

The sensor alignment aid is activated by pressing the ENTER key. During this procedure the laser sensors flash alternately.

The congruence of the laser beam path can be verified with a piece of non-reflective piece of paper. For verification place the paper between the sensors in the laser beam at different positions.

A larger displacement or an angular deviation of the laser beam causes at inclined positions of the sheet measurement deviations.

At L20-3-XX-S the first pair of sensors flashes alternately 30 x per minute. The second pair of sensors flashes alternately blinks 60 x per minute and the third pair of sensors flashes alternately approx. 100x per minute.

This allows to check if the sensors are connected correctly to the appropriate cables. Press the ENTER key to exit from this parameter.

8 Operation

8.1 Quick start guide

After applying power to the unit type and the version number are briefly displayed. Afterwards the system switches into that measurement menu which was active before the unit was switched off. The operation is described in chapter 7.2.

In the measuring mode the measured value can be read on the display. The control unit automatically compares the measured value with the adjusted thresholds. The result is transmitted via the interface to the PLC and also to the front panel LEDs.

During the normal measurement process no further actions on the control units are necessary with the following few exceptions. The following situations require action directly at the control unit or an action via the PLC interface:

• Clear fault and error messages (see chapter 9 “Error messages, causes and remedies“)

8.2 Entering a measurement program

8.2.1 Entering a measurement program for the double sheet detection

• Clearing a 2-sheet condition (if configured)

Operation

1 Push the MENU key, switch to "change" with the   keys and confirm with ENTER key. 2 Enter the password (if active). 3 Switch to "program parameter" and confirm with ENTER key. 4 Select the desired program number at the control unit. 5 Enter the nominal dimension (nominal thickness of the sheet to be processed)

(only for system type “standard”). 6 Adjust lower limit (“low“) to 80% (default setting). 7 Adjust upper limit (“up“) to 120% (default setting). 8 Adjust the averaging according to the sheet length. 9 Return into the measurement mode with the MENU key.

8.2.2 Tailor Welded Blanks

At Tailor Welded Blanks (Sheet consists of two or more thicknesses) enter the thickest part of the sheet as value for nominal thickness.

8.3 Averaging time ta and Measuring time tm

Averaging time ta

Every measuring program allows to choose a time for averaging. This time is the averaging time t Possible options for averaging are 8ms, 15ms, 25ms, 50ms 100ms, 250ms. See also chapter 7.7 „Start-up“, „Program parameter 7“.

Note Basically: A longer time leads because of averaging to more

accurate measuring values.

The selection of the averaging time has influence on the maximal velocity of the sheets.

Measuring time t

The measuring time t

is the time required by the system from "measurement start" to the

outputting of the output signal.

Messung Start

Measurement Start

Ausgangssignal

Output signal

Fig. 85.: Clarification of the measuring time

The measurement time tm is derived from the sum when operating via I/O inputs: the set time ta for averaging and an additional delay time of 5 ms for reading the measurement. When operating via fieldbus the additional delay is 4 ms.

8.3.1 Maximal allowed transport velocity at Double Sheet Control

The maximum allowed transport velocity of the sheet depends on the sheet length and the selected

for averaging. In addition, 4 ms are needed for internal processing.

time t

At an upper threshold "up" = 120% (see program parameters) following empiric formula applies:

Max. allowed transport velocity [m/s] <

Length of sheet [mm] ta [ms] + 4ms

8.3.2 Measuring at standstill

Please notice when performing measurements at standstill:

• The minimum retention period is as long as the measurement time (the selected averaging time).

• Punctual sheet elevations and contamination, such as dust, leads to wrong measurement results.
