Safety Safety The handling of the system assumes knowledge of the instruction manual. Symbols Used The following symbols are used in this instruction manual: Indicates a hazardous situation which, if not avoided, may result in minor or moderate injury. Indicates a situation which, if not avoided, may lead to property damage. Indicates a user action.
Products which carry the CE mark satisfy the requirements of the EMC regulation 2004/108/EC ‘Electromag- netic Compatibility’ and the European standards (EN) listed therein. The EC declaration of conformity is kept available according to EC regulation, article 10 by the authorities responsible at MICRO-EPSILON MESSTECHNIK GmbH & Co. KG Königbacher Straße 15...
Safety Proper Use The measuring system is designed for use in industrial areas. It is used for measuring displacement, distance, position and elongation for in-process quality control and dimensional testing The measuring system may only be operated within the limits specified in the technical data , see Chap.
Laser Class Laser Class The sensors operate with a semiconductor laser with a wavelength of 670 nm (visible/red). The laser is operated on a pulsed mode, the pulse frequency corresponding to the measuring frequency (for example f = 10 kHz). The duration of the pulse is regulated in dependency on the object to be measured and can form an almost permanent beam (for example t = 1 up to 80 μs).
Page 10
Laser Class FDA Norm The sensor complies with all applicable laws for the manufacturer of laser devices. This system is classified by the Center for Devices and Radiological Health (CDRH) asa Class II laser device. If both warning labels are covered over when the unit is installed the user must ensure that supplemen- tary labels are applied.
Functional Principle, Technical Data Functional Principle, Technical Data Short Description The system consists of an laser-optical sensor and a Sensor signal conditioning electronics.

The ILD 22xx is an optical sensor for measurements with micrometer accuracy. Make sure it is handled care- fully when installing and operating. MICRO-EPSILON recommends the use of protective housings if the sen- sor operates in a dirty environment or higher ambient temperature, see Chap. 14.2.

Installation Sensor Cable Never bend the sensor cable by more than the bending radius of 60 mm. Never lay signal leads next to or together with power cables or pulse-loaded cables (for example for drive units and solenoid valves) in a bundle or in cable ducts. Always use separate ducts. If you extend the sensor cable subsequently, this requires a re-calibration of the complete measuring system.

Max. length 10 m (32 ft), the electromagnetic field may cause measurement uncertainty on the signal if you work with cables longer then 10 m (32 ft). MICRO-EPSILON recommends to terminate the end of the cable with 10 nF to avoid noise voltages.
Measuring Setup and Commissioning Measuring Setup and Commissioning Getting Ready for Operation, Power Supply Install sensor ILD 2200 and controller according to the mounting options, see Chap. Interconnect the sensor and the controller with the sensor cable. Interconnect the controller output with display or signal processing electronics. Connect the power cable to the controller.
Measuring Setup and Commissioning After switching-on of the supply voltage the sensor runs through an initialization sequence. This is indicated by the sensor state power avg 1 zero avg 3 reset momentary activation of all the LEDs and the two switching avg 2 in/out outputs.
Measuring Setup and Commissioning Average Setting The controller is supplied ex factory with the default setting „moving averaging, number of averaging N = 1“ (no averaging activated). Averaging has no effect on linearity. The controller is capable of the following different averaging methods: Moving average Recursive average Median...
Measuring Setup and Commissioning After completion of the measuring cycle (every 0.1 ms for a measuring frequency of 10 kHz) the internal average is calculated again and outputted. For digital outputs, averaging has no effect on the measuring frequency/data frequency. Further numbers of averaging can be programmed using the digital interface, see Chap.
Measuring Setup and Commissioning Example: N = 4 ... 0, 1, 2, 2, 1, 3 ... 1, 2, 2, 1, 3, 4 Measurement values 2+2+1+3 2+1+3+4 (n+1) Output value The first average value is output when N measurement values have been reached. The output frequency stays constant at 10 kHz.
Measuring Setup and Commissioning 6.3.5 Comparison and Impact of Averaging The effect of internal averaging in the controller is to provide an improvement in the output signal for: Measurement objects with much less backscattering than the reference material Measurement objects with structured surfaces, that is sheet metal or scratched surfaces Although this does not offer any influence on linearity, it does improve the resolution and stability of the measurements on the aforementioned surfaces.

Measuring Setup and Commissioning Error Output Circuit The error messages Error 1 and Error 2 are sent for example if there is low reflection or high penetration depth of the laser light into the target. It applies the following allocation: Pin on Sub-D 21 (+) POOR Target (unfit or no object)
Measuring Setup and Commissioning Synchronization For thickness measurement with two sensors it is essential that the two sensors measure at the same time. A time delay during the recording of the measurement corresponds to a displacement of the measurement ob- ject, that means the sensors measure at different positions.
Measuring Setup and Commissioning Release the Zero/Reset key when the required output response is shown. The output response is then saved. For verification purposes the selected combination (avg1/avg2) will flash again for a moment. Following this the controller will start up (boot) as normal, indicated by the momentary illumination of the other LEDs.

Instructions for Operating Instructions for Operating Reflection Factor of the Target Surface In principle the sensor evaluates the diffuse part of the reflected laser light, see Fig. 29. A statement concern- ing a minimum reflectance is difficult to make, because even a small diffuse fraction can be evaluated from highly reflecting surfaces.
Instructions for Operating Error Influences Color differences Because of intensity compensation, color difference of targets affect the measuring result only slightly. How- ever, 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.

Instructions for Operating Angle influence laser on Tilt angles of the target both around the X and t te the Y axis of less than 5 ° only have a disturbing optoNCDT effect with surfaces which are highly reflecting. Tilt angles between 5 ° and 15 ° lead to an apparent distance change of approximately 0.12 ...

Instructions for Operating Optimising the measuring accuracy by Color strips Direction of movement means of special sensor arrangement In case of rolled or polished metals that are moved past the sensor the sensor plane must be arranged in the direction of the rolling or grinding marks.
Instructions for Operating Cleaning the Protective Glasses A periodically cleaning of the protective housings is recommended. Dry cleaning This requires a suitable optical antistatic brush or blow off the panels with dehumidified, clean and oil free compressed air. Wet cleaning Use a clean, soft, lint-free cloth or lens cleaning paper and pure alcohol (isopropanol) for cleaning the protec- tive housing.
