- It is used

ƒ for measuring displacement, distance and position

ƒ for in-process quality control and dimensional testing

- The system must only be operated within the limits specified in the technical data, see Chap. 3.3

.

- The sensor must be used in such a way that no persons are endangered or machines and other material goods are damaged in the event of malfunction or total failure of the sensor.

- Take additional precautions for safety and damage prevention in case of safety-related applications.

1.5 Proper Environment

Laser Safety

Never deliberately look into the laser beam!

Consciously close your eyes or turn away immediately if ever the laser beam should hit your eyes.

2. Laser Safety

The optoNCDT 1750 sensors operate with a semiconductor laser with a wavelength of 670 nm

(visible/red) resp. 405 nm (visible/blue). The sensors fall within Laser Class 2 (II). The laser is operated on a pulsed mode, the average power is ≤ 1 mW. The pulse frequency depends on the adjusted measuring rate

(0.3 ... 7.5 kHz). The pulse duration of the peaks is regulated depending on the measuring rate and reflectivity of the target and can be 0 up to 3333 µs.

i

Comply with all regulations on lasers!

Although the laser output is low looking directly into the laser beam must be avoided. Due to the visible light beam eye protection is ensured by the natural blink reflex. The housing of the optical sensors may only be

opened by the manufacturer, see Chap. 12.

For repair and service purposes the sensors must always be sent to the manufacturer.

Lasers of Class 2 (II) are not subject to notification and a laser protection officer is not required.

The following warning labels must be attached to the cover (front and/or rear side) of the sensor housing.The laser warning labels for Germany have already been applied. Those for other non German speaking countries an IEC standard label is included in delivery and the versions applicable to the user’s country must be ap-

plied before the equipment is used for the first time. Laser operation is indicated by LED, see Chap. 5.3

Functional Principle, Technical Data

3. Functional Principle, Technical Data

3.1 Short Description

The optoNCDT 1750 uses the principle of optical triangulation, that is, a visible, modulated point of light is projected onto the target surface.

The diffuse part of the reflection of this point of light is displayed depending on distance on a position-resolving element (CMOS) by an receiver optic which is arranged to the optical axis of the laser beam in a defined angle.

A signal processor in the sensor calculates the distance of the point of light on the measuring object to the sensor by means of the output signal of the CMOS elements. The distance value is linearized and output by means of the analog or RS422 interface.

Functional Principle, Technical Data

3.2 Real Time Control (RTSC)

The CMOS element determines the intensity of incident light during the exposure. This enables the sensor to compensate for fluctuations in brightness on the object being measured. What is more, it does so in a range from almost total absorption to almost total reflection. The RTSC (Real-Time-Surface-Compensation) allows an accurate real-time surface compensation in the measurement process with a high dynamic range.

5.1 Instructions for Installation

5.1.1 Reflection Factor of the Target Surface

In principle the sensor evaluates the diffuse part of the reflected laser light.

Laser beam

Laser beam

Laser beam

2

 optoNCDT 1750

Ideal diffuse reflection

Direct mirror reflection Real reflection

Fig. 5 Reflection factor of the target surface

A statement concerning a minimum reflectance is difficult to make because even a small diffuse fraction can be evaluated from highly reflecting surfaces. This is done by determining the intensity of the diffuse reflection

from the CMOS signal in real time and subsequent compensation, see Chap. 3.2

. Dark or shiny objects being

measured, e.g. black rubber, may require longer exposure times. The exposure time is dependent on the measuring rate and can only be increased by reducing the sensor’s measuring rate.

5.1.2 Error Influences

5.1.2.1 Light from other Sources

Thanks to their integrated optical interference filters the optoNCDT 1750 sensors offer outstanding performance in suppressing light from other sources. However, this does not preclude the possibility of interference from other light sources if the objects being measured are shiny and if lower measuring rates are selected.

Should this be the case it is recommended to use suitable shields to screen the other light sources. This applies in particular to measurement work performed in close proximity to welding equipment.

Page 23

Installation

5.1.2.2 Color Differences

Because of intensity compensation, color difference of targets affect the measuring result only slightly. However, such color differences are often combined with different penetration depths of the laser light into the material. Different penetration depths then result in apparent changes of the measuring spot size. Therefore color differences in combination with changes of penetration depth may lead to measuring errors.

5.1.2.3 Temperature Influences

When the sensor is commissioned a warm-up time of at least 20 minutes is required to achieve uniform temperature distribution in the sensor. If measurement is performed in the micron accuracy range, the effect of temperature fluctuations on the sensor holder must be considered. Due to the damping effect of the heat capacity of the sensor, sudden temperature changes are only measured with delay.

5.1.2.4 Mechanical Vibration

If the sensor is to be used for resolutions in the μm to sub-μm range, special care must be taken to ensure stable and vibration-free mounting of sensor and target.

5.1.2.5 Movement Blurs

If the objects being measured are fast moving and the measuring rate is low, it is possible that movement blurs may result. Always select a high measuring rate for high-speed operations, therefore, in order to prevent errors.

optoNCDT 1750 Page 24

Installation

5.1.2.6 Surface Roughness

Laser-optical sensors detect the surface using an extremely small laser spot. They also track slight surface unevenness. In contrast, a tactile, mechanical measurement, e.g. using a caliper, detects a much larger area of the measurement object. In case of traversing measurements, surface roughnesses of 5 μm and more lead to an apparent distance change.

Suitable parameters for the averaging number may improve the comparability of optical and mechanical measurements.

 h > 5 µm

Ceramic reference surface Structured surface

Recommendation for parameter choice:

The averaging number should be selected in such a way that a surface area the size of which is comparable to those with mechanical measurements is averaged. optoNCDT 1750 Page 25

Installation

5.1.2.7 Angle Influences

Tilt angles of the target in diffuse reflection both around the X and the Y axis of less than 5 ° only have a disturbing effect with surfaces which are highly reflecting. Tilt angles between 5 ° and 15 ° lead to an apparent

distance change of approximately 0.12 ... 0.2 % of the measuring ranges, see Fig. 6 .

These influences have to be explicitly considered when scanning profiled surfaces. Basically the angle behavior of triangulation is liable to the reflectivity of the measuring object surface. sensor off

5.4.9 Connector and Sensor Cable

appr. 315 3 ... 40 m 90 mm optoNCDT 1750

ILD1750 with pigtail PC1700 with open ends

Never fall below the bending radius for the sensor cable of 55 mm (dynamic). i

The fixed connected sensor cable is cable carriers suitable.

i

Unused open cable ends must be insulated to protect against short circuits or malfunction of the sensor.

MICRO-EPSILON recommends to use the cable carriers suitable standard connection cable PC1700 of the

optional accessories, see Chap. A 1 .

The connector and the cable component are marked with red markings which have to be aligned opposite each other before connection. In addition, they come with guidance grooves to prevent them from being wrongly connected. To release the plug-in connection, hold the plug-in connector on the grooved grips (outer sleeves) and pull apart in a straight line. Pulling on the cable and the lock nut will only lock the plug-in connector (ODU MINI-SNAP FP - lock) and will not release the connection.

Mount the cable connector if you use a cable carriers suitable sensor cable PC1700.

Avoid excessive pulling to the cables. Provide strain relieves near the connectors when cables > 5 m are vertically free hanging.

Do not twist the connectors in opposite directions when connected.

Page 40

Installation

Connect the cable shield to the potential equalization (PE, protective earth conductor) on the evaluator

(control cabinet, PC housing) and avoid ground loops.

Never lay signal leads next to or together with power cables or pulse-loaded cables (e.g. for drive units and solenoid valves) in a bundle or in cable ducts. Always use separate ducts.

Recommended strand cross-section for self-made connection cables: ≥ 0.14 mm² (AWG 25).

Operation

6. Operation

6.1 Getting Ready for Operation

Install and assemble the optoNCDT 1750 in accordance with the instructions set out, see Chap. 5.

Connect the sensor with the indicator or monitoring unit and the power supply.

The laser diode in the sensor can only be activated if at the input Laser on/off Pin 9 is connected with Pin 6, see Chap. 5.4.4

.

Once the operating voltage has been switched on the sensor runs through an initialization sequence. This is indicated by the momentary activation of all the LEDs. Once initialization has been completed, the sensor transmits a „->“ via the RS422 interface. The initialization takes up to 3 seconds.

For reproducible measurements the sensor typically requires a start-up time of 20 minutes.

If the LED output is off, this means that there is no supply voltage.

If the LED state is off, this means that the laser light source has been switched off.

Page 50

Operation

There is no linear relationship between the position of the peaks in the video signal and the output measurement value.

6.3 Programming via ASCII Commands

As an added feature you can program the sensor via an ASCII interface, physically the RS422. This requires,

that the sensor must be connected either to a serial RS422 interface via a suitable interface converter, see

Chap. A 1

, or a plug-in-card to a PC / PLC. ay attention in the programs used to the correct RS422 default setting.

Once connected, you can transmit the commands via the terminal to the sensor.

6.4 Timing, Measurement Value Flux

The sensor requires four cycles for measurement and calculation without triggering:

Each cycle takes 133.3 μs at a measuring rate of 7.5 kHz. The measured value N is available at the output af ter four cycles. The delay between acquisition and output is therefore 553 µs. As the processing in the cycles occurs parallel, after another 133.3 µs, the next measured value (N+1) is output.

7.4 Synchronization

7.4.1 Synchronization via Sync +/- Connections

If two or more optoNCDT 1750 measure against the same target, the sensors can be synchronized.

The optoNCDT 1750 distinguishes between two types of synchronization.

Type

Simultaneous synchronization

Alternating synchronization

Both sensors measure in the same cycle

Both sensors measure alternatively

Output rate ≤ measuring rate / 2

Used for

Measurement of differences (thickness, difference in height) on opaque objects. Here, Sensor 1 must be programmed as the “Mas-

ter“ and Sensor 2 as the “Slave“, see Chap. 7.3

.

Thickness measurements on translucent objects or measurements of difference on closely spaced measurement points. The alternating synchronization requires that the lasers are switched on and off alternately so that the two sensors do not interfere with each other optically. Therefor one sensor is to program as “Master alternating“ and one as “Slave alternating“. There can be only one master to be connected to a slave.

7.5.3 Triggering

7.5.3.1 General

The value input and output on the optoNCDT 1750 can be controlled through an external electrical trigger signal or commands. Both analog and digital outputs are affected. The measured value to the trigger point is

output delayed, see Chap. 6.4

.

- Triggering does not influence the preset measuring rate or the timing so that 4 cycles + 1 cycle (jitter) are between the trigger event (level change) and the output reaction

- Micro-Epsilon does not recommend any data reduction e.g. by subsampling when the trigger is used.

- The multi-function or synchronization inputs are used as external trigger inputs, see Chap. 5.4.6.

- Factory settings: no triggering, the sensor starts transmitting data output as soon as it is switched on.

“Trigger in” pulse duration is at least 50 μs.

The triggering of the measured value recording and output have the same timing.

Measurement value output can also be stopped via a command.

Setting Sensor Parameters

7.5.3.2 Triggering Data Recording

The data recording trigger processes measurements which are recorded from the trigger event. Previously acquired measurement values are rejected. The record triggering therefore directly influences the subsequent processing of measured values. In particular, the average calculation only includes values measured from the trigger event.

Activating the data recording trigger deactivates the data output trigger.

7.5.3.3 Triggering Data Output

Measurement values are calculated continuously and independently of the trigger event. A trigger event simply triggers the value output via a digital or an analog interface. Therefore, any values measured immediately before the trigger event are included in calculating mean values (averages).

Activating the data recording trigger deactivates the data recording trigger.

optoNCDT 1750

Measurement averaging is performed after the distance values have been calculated, and before they are issued through the relevant interfaces.

Averaging

- improves the resolution,

- allows masking individual interference points, and

- ‘smoothes’ the reading.

Linearity is not affected by averaging.

The average values are continuously recalculated with each measurement. The desired averaging depth is only achieved after the number of recorded measurement values corresponds at least to the averaging depth. i

The defined type of average value and the averaging number must be stored in the sensor to ensure they are hold after it is switched off.

Page 66

Setting Sensor Parameters

Averaging has no effect on the measuring rate or data rate in case of digital measurement value output. The averaging numbers can also be programmed via the digital interfaces. The optoNCDT 1750 sensor is delivered with “Median 9” as factory settings, i.e. median averaging over 9 measurement values.

Depending on the type of average and the number of averaged values, different transition response times

result thereof, see Chap. 6.4

.

7.6.2.2 Moving average

The definable number N for successive measurements (window width) is used to calculate the arithmetic average M mov

according to the following formula:

N k=1

MV (k)

N

MV Measurement value,

N k

Averaging number,

Running index

M

gl

Averaging value respectively output value

Methods:

Each new measured value is added, and the first (oldest) value is removed from the averaging (from the window). This produces short response times for measurement jumps.

Example: N = 4

... 0, 1, 2, 2, 1, 3

2, 2, 1, 3

Averaging value respectively output value

Methods:

The weighted value of each new measured value MV(n) is added to the sum of the previous average values

(n-1).

Special features:

Recursive averaging allows for very strong smoothing of the measurements, however it requires long response times for measurement jumps. The recursive average value shows low-pass behavior. Range of values for the averaging number N is 1 ... 32768.

7.6.2.4 Median

A median value is formed from a preselected number of measurements.

Methods:

The incoming measured values (3, 5, 7 or 9 measurement values) are also sorted again after each measurement. Then, the average value is provided as the median value. 3, 5, 7 or 9 measured values are taken into account for the calculation of the median, i.e. there is no median 1.

Special features:

This averaging type suppresses individual interference pulses. However, smoothing of the measurement curves is not very strong.

Example: average value from five readings

... 0 1 2 4 5 1 3

7.6.3 Zeroing and Mastering

Use zeroing and setting masters to calculate the measurement value based on a selectable reference value and to output it. This shifts the output range. This feature can be useful, for example, when several sensors carry out measurements simultaneously in thickness and planeness measurements.

optoNCDT 1750

Mastering (setting masters) is used to compensate for mechanical tolerances in the sensor measurement setup or to correct chronological (thermal) changes to the measuring system. The master value, also called calibration value, is defined as the target value. The master value is the reading that is issued as result of measuring a master object. Zeroing is when you set a master with 0 (zero) as the master value. When setting a master, the sensor characteristic is moved in parallel. Moving the characteristic reduces the relevant measuring range of a sensor (the further master value and master position are located, the greater the reduction).

Setting masters/Zeroing – Step-by-Step:

Place target and sensor into their required positions.

Send the master command.

The master command waits for a maximum of 2 seconds for the next measurement value and uses this as master value. If no value is measured within this time, e.g. in case of external triggering, the command returns with the error „E220 Timeout“. After setting the master, the sensor will issue new readings that relate to the master value. If you click the Inactive button to undo the mastering process, the system reverts to the state that existed before the master was set. An invalid master value, e.g. no peak present, is acknowledged with the Error E602 Master value is out of range .

7.6.5 Data Reduction, Output Data Rate

Data reduction

Reduction relates to

Value

RS422 / Analog

Indicates the sensor which data is to be excluded from output, thus the data amount to be transmitted is reduced.

Interfaces to be used for undersampling are to be selected via the checkbox.

You can reduce the measurement output in the sensor if you set the output of every nth measurement value in the web interface or by command. Data reduction causes only every nth measured value to be output. The other measurement values are rejected. The reduction value n can range from 1 (each measurement value) to 3,000,000. This allows you to adjust slower processes, such as a PLC, to the fast sensor without having to reduce the measuring rate.

7.7.4 Switching Outputs

The two switching outputs can be used independently of each other for error or limit value monitoring of the output value Distance 1 .

Measuring range error

Target outside the measuring range, target is absent or inappropriate target (too dark, metallic polished, insufficient reflection).

Distance outside scaled analog range

If the distance is outside the scaled range, the switching output is activated.

side limit values

If the value exceeds or falls below a defined limit, the switching outputs are activated. If limit value monitoring is chosen with both switching outputs, warning and alarm thresholds can be realized.

The switching outputs are activated depending on the set switching behavior.

When exceeding the upper limit value (maximum), the assigned switching output 1 is activated (conductive) and is then deactivated again when the next hysteresis value is not reached. The same applies when the lower limit value (minimum) is not reached. Switching output 2 reacts to a measuring range violation. The function of the switching outputs is generally independent of the analog output.

Digital Interfaces RS422

8. Digital Interfaces RS422

8.1 Preliminary Remarks

The interface RS422 has a maximum baud rate of 4 MBaud. The factory-set baud rate is 921.6 kBaud.

Data format: Measurement values in binary format, commands as an ASCII string.

Interface parameter: 8 Data bits, no parity, one stop bit (8N1).

i

Disconnect or connect the D-sub connection between RS422 and USB converter when the sensor is disconnected from power supply only.

8.2 Measurement Data Format

18 bits are transmitted per output value. An output value is divided into three bytes that differ in the two most significant bits. The transmission of additional output values is optional.

is in the H byte 1. Depending on the measuring rate, baud rate and output data rate output all data can be output in one block. If data output is overloaded, an error value is transmitted within the distance value. Use the command GETOUTINFO_RS422 to query for data selection and output sequence.

optoNCDT 1750 Page 98

Digital Interfaces RS422

8.3 Conversion of the Binary Data Format

For conversion purposes the H-Byte, M-Byte and L-Byte must be identified on the basis of the two first bits

(flag bits), the flag bits deleted and the remaining bits compiled into a 18 bit data word.

Result of conversion:

D17 D16 D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0

Conversion must be done in the application program. i

The sensor continues to deliver measurement values to the RS422 output even while communicating with the sensor.

For the data transmission with a PC the MICRO-EPSILON IF2008 PCI BUS interface card is suitable. This can be connected to the sensor via the PC1700-x/IF2008 interface cable, which is also available as an option. The

IF2008 combines the three bytes for the data word and saves them in the FIFO. The 18 bits are used for measurement values and error values. As standard, the IF2008 interface card is suitable for connecting two or (via a Y intermediate cable available as an option) up to four sensors plus two additional incremental encoders.

For further information, please refer to the descriptions of the IF2008 interface card and associated MEDAQlib driver program.

Cleaning

9. Cleaning

Cleaning of the protective screens is recommended periodically.

Dry Cleaning

Therefore an optics anti-static brush is suitable or bleeding the screen with dehumidified, clean and oil-free compressed air.

Wet Cleaning

For cleaning the protective screen use a clean, soft, lint-free cloth or lens cleaning paper with pure alcohol

(isopropyl).

Never use standard glass cleaner or other cleaning agents.

optoNCDT 1750 Page 100

Protective Housing optoNCDT 1750

10. Protective Housing

The protective housing are designed to be used especially if the sensor operates in diffuse reflection mode and in a dirty environment or higher ambient temperature. It is available as an accessory. If these protective housings are used, the linearity of the sensors in the complete system may deteriorate. For the sole purpose of protection against mechanical damage a simple protective shield with sufficiently large opening is therefore more advantageous. Installation of the sensors in the protective housings should be performed by the manufacturer, because especially in case of short reference distances the protective window must be included in the calibration.

10.1 Versions

- SGH size S, M: without air purging (with inlet and exhaust for cooling) and

- SGHF size S, M: with air purging.

10.2 Guidelines

- The maximum ambient temperature within the protective housing is 45 °C.

- The requirements for compressed-air are:

ƒ

Temperature at the inlet < 25 °C

ƒ

The compressed-air must be free of oil and water residues. It is recommended to use two oil separators in series arrangement.

- With a flow rate for example 240 l/min (2.5E+5 Pa or 36.2 psi) the maximum outside temperature is 65 °C.

- For higher ambient temperatures it is recommended to use an additional water-cooled carrier and cover plates outside the protective housing.

- No direct heat radiation (including sunlight!) on the protective housing. In case of direct heat radiation additional thermal protective shields must be installed.

- It is recommended that the protective window is cleaned from time to time with a soft alcohol-soaked cloth or cotton pad.

10.3 Delivery

The rotatable plug-nipple glands type LCKN-1/8-PK-6 (FESTO) for the compressed-air tubes with a inner diameter of 6 mm, the air plate (SGHF) and the sensor fastening accessories are included in the delivery of the protective housing.

Anhang | ASCII Communication with Sensor

A 3 ASCII Communication with Sensor

A 3.1 General

The ASCII commands can be sent to the sensor via the RS422 interface. All commands, inputs and error messages are effected in English.

One command always consists of a command name and zero or several parameters, which are separated by blanks and are completed with LF. If blanks are used in parameters, the parameter must be set in quotation marks.

Example: Switch on the output via RS422

OUTPUT RS422

Advice: must include LF, but may also be CR LF.

Declaration: LF Line feed (line feed, hex 0A)

CR Carriage return (carriage return, hex 0D)

Enter (depending on the system System hex 0A or hex 0D0A)

The currently set parameter value is returned, if a command is activated without parameters.

The input formats are:

<Command name> <Parameter1> [<Parameter2> […]]

<Command name> <Parameter1> <Parameter2> ... <Parameter...> or a combination thereof.

Parameters in []-brackets are optional and require the input of the parameter standing in front. Sequent parameters without []-brackets are to input compulsory, that is, it must not be omitted a parameter.

Alternative inputs of parameter values are displayed separately by „|“, for example the values „a“, „b“ or „c“ can be set for “a|b|c“. Parameter values in <> brackets are selectable from a value range.

optoNCDT 1750 Seite 109

Anhang | ASCII Communication with Sensor

Declarations on format:

„a | b“

„ P1 P2“

Value of the parameter can be set to the value “a“ or “b“.

It requires that both parameters “P1“ and “P2“ are set.

„<a>“ The value of the parameter lies in a value range of “... to …“, see parameter description.

Parameter values without peak brackets can only assume discrete values, see parameter description.

Parantheses are to be understood as a grouping, that is, for a better articulation „P1 P2 | P3“ is written as

„(P1 P2)|P3“.

Example without []:

„PASSWD <Old password> <New password> <New password>“

- To change the password, all three parameters are to be input.

The output format is:

<Command name> <Parameter1> [<Parameter2> […]]

The reply can be used again as command for the parameter setting without changes. Optional parameters are only returned, if the returning is necessary. For example, the activated output values are returned by command Data selection additional values. After processing a command always a return and a prompt (“->“) is returned. In the case of an error an error message is before the prompt, that begins with „Exxx“, where xxx is a unique error number. Also warnings („Wxxx“) can be output instead of error messages.

These are analogous to the error messages. In case of warnings the command is executed.

The replies to the commands GETINFO and PRINT are useful for support requests to the sensor, because they contain sensor settings.
