6. Installation Instructions During use of the sensor, applicable electrical and mechanical regulations, standards and safety precautions must be adhered to. The sensor must be protected against mechanical influences. When installing the sensor it must be ensured that direct eye contact with the laser beam is avoided. The laser warning must be plainly visible.
6.1. Default Settings PNBCxxx IP address 192.168.0.225 Subnet mask 255.255.0.0 Evaluation method Average filter 0 (corresponds to the off state) Sampling rate Auto Output rate 10 kHz Laser Auto Offset 0.0 mm Analog mode 4 to 20 mA Ext. teach-in: O3 Ext.
8. Function Descriptions PNCB High-Performance Distance Sensors work with a high resolution CMOS line array and determine dis- tance by means of an angular measurement at a sampling rate of up to 30 kHz. The sensor is equipped with integrated electronics and no additional controller is required as a result. Ascertained distance values are read out as process data via the interface and at the analogue output with16- bit resolution.
The following peak evaluation methods (algorithms) are available: 8.1. Evaluation method 8.1.1. Center of Gravity (Cog) The Cog evaluation method calculates the peak’s center of gravity, whose×-coordinate is the sought crude result. The peak has to be separated from the “sink” for the purpose of center of gravity analysis, which neces- sitates calculation of the so-called sink height.
8.2. Measuring Accuracy and Error Influence 8.2.1. Calibration Report A calibration report is included with the sensor, which graphically represents linearity error as a percentage for the measured value on a matte white surface. The following is an example of a calibration report: Calibration Protocol Order Number: PNBC001...
8.2.2. Surface Material Possible objects to be measured include all sorts of materials such as metal, plastic, ceramic, rubber and pa- per. Suitability for use only needs to be tested individually for highly reflective surfaces and liquids. 8.2.3. Surface Damage on the Object to be Measured A scratch on the surface of the object to be measured which runs perpendicular to the axis of the lens may cause stronger light emissions, whose maxima are located next to the center of the spot.

In order to be able to access the product’s website (in this example the PNBC002), the IP address must be entered to the browser’s address line as described. Default IP address: 192.168.0.225 The initial page appears with general information concerning the connected sensor.
9.1. Page Layout (website) The website is subdivided into the following areas: Language selection The website can be changed from English (default language) to other languages with the language selection function. Status display Current status messages are displayed: Measured value: Displays the current distance between the edge of the sensor’s housing and the object.
Page content Depending on which category is selected in the menu at the left-hand side of the page, respective page content appears here. Category selection The settings are subdivided into the following categories: • General device information: Overview page with general information regarding the sensor as a display without any setting options.
– The larger the selected value, the more smoothed the measured value becomes. Sampling rate: Possible settings include “Auto” (the sampling rate is adjusted automatically) or “= out- put rate” (sampling rate = output rate). Values can be selected within a range of 900 to 30,000 Hz as well.

90° E1/A 5...24 V Displacement E2/B 5...24 V Displacement • Encoder E1+E2: A 2-channel rotary encoder with HTL square-wave signal must be used. Channel A is displaced 90° relative to channel B. It must be assured that a shielded cable is used in order to avoid pos- sible interference or crosstalk between the conductors.
• Do not clean with solvents or cleansers which could damage the product. 11. Proper Disposal wenglor sensoric GmbH does not accept the return of unusable or irreparable products. Respectively valid national waste disposal regulations apply to product disposal. Subject to change without notice...
