1. System summary


The function principle of the Checkbox is based on:

– the contactless recognition of small parts

– the teaching of new parts without programming

– an integrated quality check.

Identification A small parts conveyor separates the individual parts andpasses them on to the conveyor device. The conveyor device(e.g. conveyor belt, linear axis) can be fitted with a maximumof 3 actuators for returning or separating the conveyed parts.

The Checkbox registers each part in contour pictures. Fromthe contours the system ascertains part-specific featuressuch as length, height and surface. On the basis of the fea-tures the Checkbox recognizes:

– the parts type

– the orientation

– the dimensional accuracy

– the quality.

Teaching The nominal contour of a conveyed part is ascertained by asimple procedure:

1. You “show” the Checkbox samples of the conveyed parttype several times one after the other (= scan) in thenominal orientation.

2. You scan the sample parts in further orientations ifrequired.

3. You save the features of the parts type as Teach data.

4. You test the Teach data in the test mode.

1. System summary


Testing Each registered conveyed part is compared with the savedTeach data and then sorted into different types. The test partsare separated basically via 3 conveying paths:

– Good parts are passed on e.g. to an assembly system.

– Incorrectly oriented parts are returned to the small partsconveyor.

– Faulty or foreign parts (bad parts) are rejected.

1. System summary


1.5 Buffer zone

The buffer zone serves as a parts buffer for the next machinee.g. an assembly system.

The Checkbox can monitor the highest and lowest fillingstates of the buffer zone and if the jam of parts is long, it canswitch the small parts conveyor on or off as required.(Buffer zone check, see Fig. 1/2).

Additionally by means of a second sensor, the small partsconveyor can be switched to delay. (Buffer zone check withhysteresis, see Fig. 1/3).

The buffer zone inputs are processed by the Checkbox with adebounce time. The sensor signal is only evaluated if it ispresent for at least 1 second. This delay prevents each con-veyed part from triggering the signal “Buffer zone full” whenit passes the sensor.

The delay time of 1 second between the registering of a con-veyed part by the sensor and the interpretation of the signalby the Checkbox must be taken into account when the bufferzone sections are planned.

Planning the size of the buffer zone

The buffer zone sections (see Fig. 1/2) must be dimensionedso that uninterrupted operation of the machine is possible.Instructions on dimensioning the buffer zone can be found inthe following table.

1. System summary


Dimensioning the buffer zone

A Section between the transporting device and the sensor.Section A must accept all conveyed parts which liebetween the Checkbox and the sensor when a conveyedpart has been registered by the sensor. The lengthdepends on:– the geometry of the conveyed parts– the maximum feeder rate of the small parts conveyor– the length of the transporting device

B Section between the sensor and the next machineWhen the small parts conveyor is switched on again,uninterrupted operation of the assembly system must beguaranteed until the first new conveyed parts arrive.Section B must be designed so that a sufficient number ofconveyed parts can be made available. The lengthdepends on:– the geometry of the conveyed parts– the maximum time delay between switching on the

small parts conveyor again and making the newconveyed parts available

– the length and speed of the transporting device– the average feed amount of good parts in the nominal

orientation.

AB *) Section between sensors 1 and 2 (Fig. 1/3).Section AB determines the switching delay (hysteresis)of the small parts conveyor for regulating the supply ofparts. The longer the section is, the less the switchingfrequency.

*) Set the “Number of buffer zone sensors = 2” with CheckKon

2.2 Mounting

Transport Always transport the Checkbox in its original packing; furthertransport safety devices are not necessary.

Mounting location Observe especially the following conditions:

– the mounting location must be free of vibration

– there must be stable mechanical fastening

– the ambient air must be clean: free of oil, no paint spray,no grinding dust

– Screening of external light influences and extrememagnetic fields (e.g. due to induction furnaces).

In this way you will achieve optimum test results and ensurea long service life of the device.

Conveyor device In order that the test results can be reliable and reproducible,the conveyor device used should fulfill the following require-ments:

� Use a high-grade transporting system which conveys theparts at a constant speed.

� Ensure the stable position of the parts, e.g. by means ofmechanical devices.

� Use also mechanical devices to secure the parts transferfrom the conveyor device to the buffer zone (e.g. droppipe, slide, waste) of the subsequent machine.

Space requirement Note the space required for mounting the Checkbox. Thedimensions of the Checkbox and specifications on weight canbe found in the Appendix A.5.

Fastening On the side of the Checkbox there is a mounting profile withdovetail guide.



A connecting kit (type HMSV-12) is available as an accessoryfrom Festo.

Caution• Check within the framework of your EMERGENCY STOPconcept to ascertain the measures necessary for puttingyour machine/system into a safe state in the event of anEMERGENCY STOP (e.g. switching off the operatingvoltage, switching off pressure).

Preparing plugs and cables

Use plugs and sockets from the Festo supply programmewhich match the outer diameter of the cables used(www.festo.com/catalogue).

NoteIn this way, you will avoid interference from electromag-netic influences:

• Use only screened cable.

• Use large-cross-section cable that is as short as possible.

• Connect both the FE earth terminal and the cablescreening with low impedance to the earth potential.

Connection Plugs/sockets

Power supply socket PG 9 or PG 13.5

Sensors, actuators PG 7

Tab. 2/2: Connection

In order to guarantee observance of the IP protection classfor the completely fitted Checkbox:

� tighten the union nuts of the plugs by hand

� seal unused sockets with the protective caps supplied.

CautionLong I/O signal lines reduce the resistance to interference.

• Comply with the maximum permissible I/O signal linelength of 30 m.



2.3.1 Selection of the power supply unit

The power supply for the Checkbox must fulfill the followingrequirements:

– voltage range: 24 V ± 15 %

– Power rating: 18 W with load-free outputs

– no current consumption at the outputs

In order to comply with the EMC limits, the Checkbox isequipped with a filter for the operating voltage. Use aseparate power unit for the Checkbox. Only in this way canthe fitted filter be effective.

Warning• Use only power sources which guarantee reliableelectrical isolation of the operating voltage as perIEC/EN 60204-1. Observe also the general requirementsfor PELV power circuits as per IEC/EN 60204-1.



2.3.2 Connection of the operating voltage

� Use an operating voltage cable with sufficientcross-sectional area.

� Avoid long distances between the power supply unit andthe Checkbox. Long operating voltage cables reduce thevoltage supplied by the power unit.

� Protect the supply cable with a 5 A cut-out fuse with me-dium time-lag.

Connect the Checkbox to the operating voltage as follows:

Pin 24 V DC plug

1 Do not connect

2 +24 V DC, +/- 15 %with 5 A medium time-lag fuse

3 GND

4 Do not connect

Tab. 2/3: 24 V DC connection plug

Use only a 4-pin M18 socket for the power supply andconnect this only to the connection for the power supply.

1. Connect the plug to the 24 V DC connection on theCheckbox.

2. Tighten the union nuts of the plug by hand.



2.3.3 Power supply for external components

If you connect the Checkbox via the connections PLC,ACTUATOR or BUFFER/FEEDER with other devices(e.g. PLC, conveyor device), observe the following:

NoteIn order to comply with the EMC limits, the Checkbox isequipped with a filter for the operating voltage.

A connection between the 24 V potential and GND at the24 V DC plug with other plugs on the Checkbox or withother devices will in some cases bridge the installed filter.Asymmetries of the currents in the outgoing and returnlines will reduce the effect of the filter.

� Use a separate power unit for the Checkbox. Provide aseparate power supply for connected current-consumingdevices.

� Do not connect the 24 V potential and GND at the“24 V DC” connection of the Checkbox with other plugsof the Checkbox or with other devices.

� Make sure that the currents of the inputs and outputsflow via the Checkbox and not directly to the power unit.

Consuming devices can also be supplied with voltage via thePLC plug. Observe also the information in Chapter 3.6.



2.4 Adapting system parameters with CheckKon

A password is required for CheckKon for setting the systemparameters and transmitting the modifications to theCheckbox (Function “Modify system”). You can obtain yourpassword via the service hotline +49 / 711 / 347-1610. Thefunction “Observe system” can be used without a password.

1. Install CheckKon on your diagnostic PC. Notes oninstallation can be found in the software manual.

2. Connect the Checkbox at the DIAG connection with thediagnostic PC (see Chapter 3.4). Connect the devices onlywhen the power supplies are switched off.

Diagnostic mode Start CheckKon when the Checkbox has been switched on.When Checkkon is started, it carries out a system test andswitches the Checkbox to the diagnostic mode.

NoteIn diagnostic mode the Checkbox transmits additionalinformation via the diagnostic interface. During thetransmission time no parts are checked.

• Do not operate the Checkbox in diagnostic mode withthe full rate of parts.

In this way you can prevent parts from passing theactuator positions unchecked.

1. Adapt the Checkbox to your system requirements withthe system parameters in the menu [Window] [Systemparameters]. Note also the instructions in the followingchapters and in the software manual.



CheckKon shows the most important system parametersthrough the menu [Window] [System parameters] symbol“Only important parameters”. Make sure that these para-meters are adapted to your application.

2. Transfer the modified settings to the Checkbox(see software manual).

3. Conclude CheckKon and with it the diagnostic mode whenall settings have been completed.

NoteFaulty processing data can cause incorrect functioning ofthe Checkbox.

• Carry out the complete Teach procedure again if youhave modified the system parameters with CheckKon.

Controlling the actuators

NoteIf there is a failure in the power supply to the CHB-C-X or tothe actuators when the transporting device is running, thiscan result in:

• parts passing the actuator positions unchecked

• the actuators being unable to sort out checked parts.

Check the measures which are required on your machine/system in order to prevent incorrectly oriented parts orbad parts from unintentionally reaching the next machinein the event of such operating faults.

Input I/19 on the PLC plug is intended for monitoring thepneumatic supply to the actuators. In the event of a fault thisinput will switch the Checkbox to error status E 01 by meansof a pressure switch.

3. The I/O module


The CHB-C-X can control up to 3 actuators for sorting outgood parts, incorrectly oriented parts and bad parts. Possibleactuators are e.g. shunts, reversing stations or air nozzleswhich sort out the parts at certain positions on thetransporting device depending on the test result. The numberand assignment of the actuator positions may vary dependingon application. The assignment of the actuator positions canbe adapted with the CheckKon software.

Example of configuration Transporting device with 2 blow-out nozzles (see Fig. 1/1)

The compressed air valves of the blow-out positions must beconnected directly with the outputs for actuators 1 ... 2.These outputs are set to +24 V DC if the parts test providesthe following result:

– incorrectly oriented or superfluous (good) part

– bad or foreign part

If the CHB-C-X recognizes an inspection part as good,the signal actuator 3 will be set from the rest potential0 V to +24 V DC and the good part will be output at the end ofthe transporting device.

Output Signal level 1) (example of configuration)

Actuator 1 There is a +24 V DC signal when the inspectionpart passes the actuator position for incorrectlyoriented or superfluous good parts.

Actuator 2 There is a +24 V DC signal when the inspectionpart passes the actuator position for bad orforeign parts.

Actuator 3 There is a +24 V DC signal when the inspectionpart passes the actuator position for good parts(here: the end of the transporting device).

1) The duration of the signal corresponds to the time required forthe part to reach the air jet nozzle.

3. The I/O module


Controlling the buffer zone sensor (buffer)

NoteOnly in this way is the Checkbox ready to operate:

• Leave non-used sensor inputs open.

Otherwise the display will show the operating status “Full”,although the buffer zone is free. All good parts will be re-turned. The small parts conveyor will be switched off after30 s (standard setting).

Signal duration In order to avoid unnecessary switching movements, theCheckbox reacts only after a certain signal duration to thesensor signals for “Buffer zone full” and “Buffer zone empty”.

Modification of the signal duration with CheckKon in the menu[Window] [System parameters]� System� Transportingsystems� Continuing systems ...� Minimum sensor signalduration for status:buffer zone full: 1.0 s (0.1 s ... 180 s)buffer zone empty: 1.0 s (0.1 s ... 180 s)

Sensor type The CHB-C-X is set at the factory for use with a buffer zonesensor, the sensor output of which lies at a potential of 0 V(negative switching) in the rest state.

Modification of the sensor type with CheckKon in the menu[Window] [System parameters]:� System� Transportingsystems� Continuing systems ...� Buffer zone sensor types= positive switching.

3. The I/O module


NoteYou can optimize the operational safety of your supplysystem as follows:

• Use sensors which have a sensor output with a potentialof 24 V DC in the rest state.

• Adapt the setting of the sensor type with CheckKon.

You can then prevent the system from becoming blockede.g. in the event of a broken cable.

3.4 DIAG

NoteIn the diagnostic mode the CHB-C-X transmits additionalinformation via the diagnostic interface. During the trans-mission time no parts are checked.

• Use the DIAG connection only for commissioning and forservicing.

• Do not operate the CHB-C-X in the diagnostic mode withthe full parts rate. In this way you can prevent partsfrom passing the actuator positions unchecked.

In order to connect a diagnostic PC use cable KDI-SB202-BU9(see Appendix A.6 Accessories).

3.6.4 Counting function

The counter function must be activated in CheckKon in themenu [Window] [System parameters]:� System� Operatingmodes� Counter configuration ...� Counter mode =activated.The function “External sensor” will then automatically beblocked.

Counter configuration Set the following parameters in CheckKon� System� Oper-ating modes� Counter configuration according to yourrequirements:� Nominal value specification = 1 (1 ... 200 million)� Counting of all good parts in each orientation = on (off )

Setting the switch-off delay of the small parts conveyorwhen the nominal number is reached� Transporting systems� Supply system ...� Switch-off time when counter status isreached = 30 s (0.1 s ... 1800 s).

Counting Depending on the setting in CheckKon, only good parts intarget orientation (counting of all good parts ... = off ) orgood parts in all taught orientations (counting of all goodparts ... = on) will be counted.

If counting is interrupted, e.g. when the Start/Stop button ispressed, the current counter states will remain saved. Whenthe device is started, counting is continued with the savedcounter states.

NoteWhen the CHB-C-X is switched off (operating voltage off ),counting will be interrupted. The current counter stateswill be deleted. When the CHB-C-X is switched on, it startsa new counter cycle.

• When the CHB-C-X is switched off, remove all good partsfrom the parts output. You will then avoid incorrect num-bers of items when the CHB-C-X is switched on again.

3. The I/O module


If the set target number of parts types is reached, all furthergood parts of the parts type up to the moment when thesmall parts conveyor is switched off will be returned to theconveyor at the actuator position for superfluous good parts.Bad parts will be output further at the relevant position.

CFul When the last good part of a counting procedure reaches theoutput position for good parts, the output O/22 on the con-nection PLC will be set from LOW> to HIGH (“Target num-ber reached”). The current counter status is ended. TheCHB-C-X shows “cFul”.

All subsequent good parts will be returned to the small partsconveyor. When the time preset with CheckKon has expired,the small parts conveyor will be switched off.

In order to start a new counting procedure, the CHB-C-Xrequires the signal “Start new cycle” from the higher-ordercontroller. In order that the counting cycle can be started, thepulse LOW> HIGH> LOW must be applied at input I/18.

During the pulse duration tsc good parts will still be returned.The new counting cycle starts with the falling edge at I/18(see following table).

Switch-on delay of the small parts conveyor

After starting, the Checkbox triggers the actuator for sortingout the bad parts. This is to ensure that no (unchecked) partsare left on the conveyor device. This results in a delay of afew seconds between the external Start command (I/6) andthe switch-on signal for the small parts conveyor (O/8). Theduration of this delay depends on ambient parameters,e.g. transporting speed and geometrical variables.

4.1 Preparing the Teach procedure

If you are using the CheckKon/CheckOpti software package:note also the instructions on preparing the Teach procedurein the software manuals.

Features and properties of the conveyed parts

The Checkbox registers conveyed parts as 2-dimensional,black and white profile pictures (parts contour). Features fordistinguishing various good parts are derived from the partscontour. Discolouring or surface faults do not influence thetest result in this recognition procedure.

The features of the conveyed part relevant for distinguishing,as well as for determining the orientation and quality, mustbe recognizable for the Checkbox:

� Use the Checkbox preferably for testing rotation-symmet-rical small parts.The testing of non-rotation-symmetrical parts is only pos-sible if a pre-orientation of the conveyed parts is carriedout with the small parts conveyor.

The conveyed part must be fed through in a safe manner onthe conveyor device:

– The length, diameter and height of a conveyed part mustbe suitable for the CHB-C-X.

– The conveyed part must be supplied in a stable orienta-tion (it must not roll away or vibrate).

The conveyed part must be sorted out reliably by theactuators.

As standard during the Teach procedure, the parts are sortedout at the first actuator position. This is to ensure that nosample parts are transported by mistake to the next machinein the process.

4. Teaching parts


NoteCheck in the test mode whether the actuators used (e.g. airnozzles) can reliably sort out especially large conveyedparts made of heavy materials with streamlined form.This is to ensure that no sample parts are transported bymistake to the next machine in the process.

Selecting the sample parts

� Provide sample parts for each parts type as follows:

– The sample parts show all the characteristics which apart classified as “Good” should possess.

– If possible, use various sample parts with theusual scatter of characteristics (recommendation:min. 6 sample parts). With the scatter of characterist-ics, you determine the extent to which the test partsclassified as “Good” may differ from each other.

Diagnostics mode

� Start CheckKon in order to display and set the systemparameters during the TEACH and test modes.

When Checkkon is started, it carries out a system test andswitches the Checkbox automatically to the diagnostic mode.

NoteIn the diagnostic mode the Checkbox transmits additionalinformation via the diagnostic interface. During the trans-mission time no parts are checked.

• Do not operate the Checkbox in diagnostic mode withthe full parts rate.

In this way you can prevent parts from passing the actu-ator positions unchecked.

4. Teaching parts


4.2 The Teach procedure

In the TEACH mode the Checkbox learns all the features forthe parts test (Teach data) when scanning sample parts.

� Carry out the Teach procedure as realistically as possible.Use, for example, the conveyor device and feed intendedfor the later AUTO mode (if necessary activate withCheckKon: [Window] [System parameters]� Transportingsystems� Supply system ...� Activate supply system inTeach mode ...).

� Start the conveyor device.

The following functions of the Teach procedure can be carriedout via the PLC interface:

– START/STOP mode

– selection of the parts type

– starting of the Teach mode

– selection of the (next) orientation

– saving of the Teach data

� Set the desired parts type via the PLC interface.

Further information can be found in Chapter 3.6

Stop• Press the button START/STOP, in order to switch the

Checkbox into the Stop status.

� Scan sample parts of the parts type one after the other inall intended orientations (max. 8), as described below.

4. Teaching parts


Scan sample parts in orientation 1

1. Press the button STATUS/TEACH, in order to switch theCheckbox to the Teach mode.

Fix If “Fix” is shown in the display and if the CHB-C-X switchesto the AUTO mode again, the STATUS/TEACH button isblocked by CheckKon. Acknowledge the message with theSTART/STOP button.

• Switch off the TEACH button blocking with CheckKon:[Window] [System parameters]� System� Operatingmodes = ...� Teach button lock = Off.

1 o1 2. Scan different sample parts of parts type 1 in orienta-tion 1 (o1 = nominal orientation). The STATUS/TEACHbutton lights up briefly when the sample part isregistered.

• Pay attention to the positioning of the sample parts(see Chapter 4.2.1).

C ... • While scanning, observe the displayed C-value of thescatter of characteristics (see Chapter 4.2.2).

• Repeat the procedure until the C-value remainsalmost constant.

If a part has been incorrectly positioned (C-value changeserratically):

� Press the button START/STOP, in order to conclude theTeach procedure.

� Repeat the complete Teach procedure of the parts type.

Scan the sample parts in further orientations

3. Check whether there is at least one feature in which thevarious orientations differ.

4. Press the STATUS/TEACH button in order to scan the nextorientation

E 20If fault E20 is shown, the nominal orientation cannot be dis-tinguished from other orientations.

Possible causes of the fault:

– The nominal orientation has been taught several times bymistake.

� Repeat the complete teach procedure. Pay attentionto the positioning of the sample parts in accordancewith the orientation shown.

– The nominal orientation is too similar to other orienta-tions.

� Optimize the Teach data with CheckOpti.

With the CheckOpti software even minimum differences in thefeatures can be recognized. Further information can be ob-tained from your technical advisor.

1 o25. Scan the sample parts of parts type 1 in orientation 2

(o2) as described in point 2.

4. Teaching parts


Save the Teach data and conclude the Teach procedure

Do not save the Teach data until the sample parts of a partstype have been taught in all orientations.

Stop 6. Press the START/STOP button.The Teach data will be saved and the TEACH mode will beconcluded.

After saving, carry out the following steps:

� Check the Teach procedure in the test mode with regardto orientation and quality as described in Chapter 5.

� Keep a record of your work.

Register the next parts type in a further Teach procedure:

� Address the next parts type via the PLC inputs(Chapter 3.6.3).

� Repeat all steps as from point 1.

4. Teaching parts


4.2.1 Positioning the sample parts

The sample parts should be positioned exactly like the partsto be tested later.

– Place the sample parts on the conveyor band one afterthe other.

– You do not need to be very careful when placing the partson the conveyor belt.

In cases where particularly different variations of theascertained parts contour (view) are permitted or possible inan orientation, you should show the “extreme” variations oras many different variations as possible during the teachprocedure.

� Show at least 6 parts of the current parts type perorientation.

� Use different parts if possible, although if necessary thesame part can be shown several times.

The parts type is not registered completely until theCheckbox has recorded all intended orientations. For reliabletesting, the ascertained features of the individual orientationsmust be clearly distinguished.

� Make sure in particular that orientation 1 (target orienta-tion) differs clearly in at least one feature from all theother orientations.

4. Teaching parts


4.2.2 Observing the scatter of characteristics

C... Observe the display when scanning the sample parts. Itshows briefly for each part the maximum value of the scatterof characteristics for the current feature which differs to thegreatest extent (C-value).

The following factors influence the scatter of characteristics:

– parts geometry

– different contours of the part, depending on the swivelangle around the longitudinal axis (e.g. with springs,screws)

– different positioning on the conveyor device.

If the displayed C-value changes erratically, you have prob-ably placed the conveyed part incorrectly on the conveyordevice. If the C-value changes only minimally, a sufficientscatter of characteristics in the current orientation has prob-ably been achieved. The optimum situation is when the curveof the values changes at first considerably and then becomesincreasingly more constant.

Small values indicate narrow manufacturing tolerances and asteady supply of parts. Very large values indicate that thetaught sample parts differ greatly from each other withregard to their properties. If the (good) parts are allowed todiffer greatly from each other, the Teach procedure cannevertheless still be continued.

C-value Significance

. 10 Sample parts are very similar in all features

, 30 Large scatter of at least one feature

An exact description of the calculation algorithm for the scatter ofcharacteristics can be found in Appendix A.3.2.

5. Testing parts


5.1 The test procedure

During the automatic inspection of workpieces, a reliablegrading of the parts to be tested must be achieved withrespect to orientation and quality (e.g. dimensions specifiedhave been observed).

The following functions can only be carried out via the PLCinterface:

– Selection of the parts type

– Counter function or test with external sensor

– Monitoring of the buffer zone with switch delay.

Further information can be found in Chapter 3.6.

� Evaluate the reliability of the Teach data in the test mode(Chapter 5.2), before you begin with the automaticinspection of workpieces.

� Protect the Teach data against undesired modification:

– through control panel protection (see Chapter 3.6.8)

– with the CheckKon software:[Window] [System parameters]� System� Operatingmodes ...� Teach button lock = On.

5. Testing parts


5.2 Test mode

Stop The Teach procedure is concluded and the Checkbox isready to operate (Stop status)

Set the desired parts type via the PLC interface (Chapter 3.6.3)

1. Provide inspection parts for each parts type

� Use good, bad and incorrectly oriented parts from theparts assortment.

� Test a sufficient number of parts in order to obtain areproducible result.Show, for example, 6 good parts per orientation aswell as 6 bad parts.

1 5 2. Press the button START/STOP (AUTO mode). Test partsfrom the displayed parts type (e.g. 1) with the factory-settolerance of 5 %.

3. You do not need to be very careful when placing the partson the conveyor belt.If possible, use the conveyor device intended for theinspection of workpieces. The inspection parts should bepositioned (at random), as in normal operation.

E 05 If the supply of parts is interrupted for a long period, theCheckbox will show fault message E 05 or warning F 05 andwill stop automatically (see Chapter 2.6 and Appendix A.1.2).

4. Check the test results e.g. with regard to the followingaspects: Have the orientations been recognized correctly?Is the grading of the parts recognized as good/badcorrect?

5. Testing parts


5. Check the correct output at the output positions for good,bad or incorrectly oriented parts with as many inspectionparts as possible.

6. On the basis of the sample parts, check the inspectionparts with regard to their grading. If you have also testedfaulty parts, check whether these have actually beenrecognized as bad.

If too many good parts have been graded and sorted outas “Bad”:

� Increase the tolerance (see Chapter 5.3)

� Repeat the Teach procedure with more sample parts,using the conveyor device intended for automaticmode (see Chapter 4).

7. Note the displays on the Checkbox.When a conveyed part is registered, the status displaylights up briefly.

The display shows for 1.5 seconds:

A...

#...

• The evaluation of the inspection part deviation A(Chapter 6.4.2)

• The evaluation of the inspection part orientation #if more than one orientation has been learnt(Chapter 6.4.3).

If the quality check and position recognition for the partsassortment are not satisfactory, you can use additionaloperating parameters and tools with CheckOpti in order tooptimize the test results. Please consult your technicaladvisor.

5. Testing parts


Terminate the test mode when all settings have been com-pleted and the checked parts have been graded reliably withregard to orientation and quality.

Stop 8. Press the button START/STOP, in order to switch theCheckbox into the Stop status.

9. Conclude the diagnostic mode. Close CheckKon (andCheckOpti).

10. Remove the diagnostic cable from the DIAG connectionand seal the connection with the protective cap supplied.

5. Testing parts


5.3 Influence of tolerance

Band width When a new parts type is taught, the features of all scannedparts are recorded. The values of the registered features dif-fer individually from each other. For each feature, there is avalue range (band width) in which test parts are graded as“Good”. You can influence this band width by means of thetolerance setting. Test parts, the features of which lie withinthe band width or in the subsequent tolerance range, are stillaccepted as good parts.

With 0 % tolerance, only those parts with features which lieexactly within the band width of the scanned sample partswill be accepted as good parts. Set therefore at least 1 %tolerance. This will ensure that good parts will be classifiedcorrectly even if their positions deviate minimally.

Set tolerance The setting is made in the Stop status.

Stop 1. Press the button START/STOP, in order to switch theCheckbox into the Stop status.

1 5

1 10

2. Press and hold down the START/STOP button whileyou increase the tolerance value by pressing theTEACH/STATUS button, e.g. from 5 to 10%:

Setting range 0 ... 20 %Standard setting 5 %Recommendation at least 1 %

Stop 3. Release the START/STOP button when the desired valuehas been set.

The value selected will be added automatically to the data ofthe parts type and saved.

5. Testing parts


Optimizing Ascertain the optimum setting of the tolerance especially withcritical conveyed parts in the test mode. Use one of thefollowing methods:

� Empirical settingVary the tolerance so that the test of a large number ofparts produces correctly recognized good and bad parts.

� Setting corresponding to inspection part deviation:

� Select sample parts which are suitable as referencefor good or bad parts. The recognition-specificfeatures should lie if possible in the limit rangegood/bad.

� Vary the tolerance so that the following test part devi-ation is shown when the limit sample part is scanned:‹ 100 limit sample part “Good”› 100 limit sample part “Bad”

5.4 Evaluation of the test results

5.4.1 Checking the features

The individual features of the inspection parts differ from theaverage values of the sample part features. The Checkboxascertains the feature which differs most (maximum deviation)for each test part.

A... During the test procedure the inspection part deviationwill be shown for 1.5 seconds. Detailed instructions on testpart deviation (arithmetical algorithm) can be found inAppendix A.3.3.

Value Evaluation Note

≤100 Good part The smaller the value,the more accurately theinspection part corres-ponds to the sampleparts.

>100 Reject part The larger the value,the less the inspectionpart corresponds to thesample parts.

Indicating range: 0 to 999

Tab. 5/1: Inspection part deviation

5. Testing parts


5.4.2 Checking the orientation

The Checkbox ascertains during the test procedure whetherthe orientation of the last scanned test part can be assignedto the orientations of the sample part.

#... The uncertainty in orientation recognition will be shownfor 1.5 seconds after the display of the inspection partdeviation.

Value Evaluation Significance

<100 Inspection partorientation can beassigned

The smaller the value,the more reliably theinspection partorientation will berecognized.

>100 Inspection partorientation cannot beassigned clearly

The larger the value,the less reliably theinspection partorientation will berecognized.

CautionDamage to components

• Before carrying out mounting, installation and/or main-tenance work, always switch off the power supply.

NoteDamage to the glass surfaces can result in operative mal-functions of the Checkbox.

• Consult your Festo Service in case of damage.

The Checkbox has been designed for rough industrialenvironments and is distinguished by its high reliability,robust structure and long service life. Special maintenancework is not necessary.

Cleaning Fixed cleaning intervals are not specified. The frequency ofcleaning depends on the conditions of use at your location.

Laser irradiationEye and skin injury

• Clean the Checkbox only in the switched-off state.

• Observe the warnings on the Checkbox.

With plastic parts, do not use solvent-containing or abrasivecleaning agents, which can damage the surfaces. Use onlymild cleaning agents free of solvents.

� Remove dirt from the housing, operating elements andconveyor belt with a soft moist cloth.

6. Maintenance


NoteFaultless functioning of the Checkbox optics can only beguaranteed if the glass surfaces are clean and notscratched. Make sure that the glass surfaces are notscratched; do not use any abrasive cleaning agents.

Clean the glass surfaces on the prism supports if they aredirty or if there are dirt deposits on them:

• with clean non-lubricated compressed air

• with a soft moist cloth and non-abrasive cleaning agents.

You will then avoid damage which could lead to malfunc-tioning of the Checkbox.
