Product Description EVK2_CP/EVM2-CP_LIC - Optical sensor positioning devices with CAN-Bus-Interface and LIC
6 BA_EVK_EVK2-CP_EVM2-CP_LIC_01_en EMG Automation GmbH
Application Increasing levels of automation and a growing importance of product quality demand a continuous detection of the strip edge position/strip width in processing lines. To satisfy this function non-contact measuring sensors (type EVK / EVM) are used to obtain information concerning the strip edge/strip centre position by using light units (type LIC) to conduct a bandpass filtering process of a high-frequency proportion of light. The sensor positioning devices are controlled in individual cases of operation via the downstream control electronics. When using sensor positioning devices of type EVK2-CP or EVM2-CP the communication and control function is conducted via the CANOpen interface. This significantly reduces the amount of wiring in comparison to predecessor EVK and EVM units. Other functions and status messages are integrated in the communication protocol, which makes maintenance options and troubleshooting measures much more straightforward. In normal circumstances a sensor positioning device is controlled in such a way that measuring photocell LS13 continuously follows the changing strip edge position. This is simultaneously accompanied by a reference photocell (type LS14), which continuously monitors the degree of light intensity and compensates any contamination present. The current actual position of the sensor positioning device is detected by an internal rotary potentiometer; it is also possible to use a digital linear stroke transducer. Application of the LIC The compact light emitter is a linear light emitter for optical strip sensing. The edge of non-transparent materials can be scanned in combination with optical receivers LS13/14 or HF-PLE/HF-PLM and the corresponding evaluation systems (e.g. EVK). A strip edge sensing system can be realised by using a servo amplifier and an actuator or two optical receivers.
The compact light emitter should not be used as a light for general illumination purposes as defined in standard DIN EN 60598 (VDE0711) or other similar standards.

EMG Automation GmbH BA_EVK_EVK2-CP_EVM2-CP_LIC_01_en 13
Configuration and function
Brief system description At least one sensor positioning device with electrically adjustable slide is arranged above the strip (two complete sensor positioning devices are also required for centre control processes or width measurements). A high frequency alternating light measuring unit, consisting of measuring and reference photocells, is assembled on the slide. A rotary potentiometer is attached to the DC motor internally to detect the current actual position. A light unit with 2 kHz supply is located below the strip. Both the light unit and the sensor positioning device(s) are supplied with power by mains adapters located in a separate enclosure. The high frequency alternating light measuring equipment is evaluated in the electronic unit on the sensor positioning device.
Effect description of the system with HF light unit The strip edge is detected by a motorised sensor positioning device, which is equipped with HF alternating light units LS13 / LS14 with protection against ambient light. If the strip edge is displaced due to a change in strip width or a lateral strip deviation, this is detected by the photocells. The superimposed control electronics then activate the DC motor or the actuator of the control circuit, in order to ensure that the strip edge always covers half of the measuring range of the photocell. Contamination of the light emitters is compensated by applying the reference principle. This involves each measuring unit using a measuring sensor and a reference sensor directed to the same bright spot of the light emitter. While the measuring photocell detects the lateral position of the strip edge the reference photocell measures the background brightness of the light spot. The elimination of ambient light disturbances through the use of HF light emitters and selective HF alternating light receivers, whose bandpass evaluation occurs within the EVK2-CP electronics, is of significant importance to the accuracy of the measurement result. The intensity of the light emitted is regulated and monitored for any malfunctions. The entire system is parameterised as standard with a laptop or PC or via a keyboard/diagnostics unit on the control electronics. When the power supply is wired accordingly a complete alignment of the measuring sensors is possible, even without CAN bus communication.
HF alternating light measuring sensors which are insensitive to ambient light Light units (LIC) are operated with a 2 kHz modulated supply voltage to eliminate influences of ambient light on the strip position detection process. The measuring signals for the HF alternating light measuring sensors are conducted through electrical filters. When doing this only the high-frequency light signal is evaluated. The brightness of the light units is maintained at a constant level by an internal control circuit, which ensures this measuring device is unaffected by ambient light or changes in voltage or temperature.

Commissioning of the sensor positioning device The traversing path of the sensor positioning device is set to the inner and outer maximum position by the manufacturer. If this needs to be changed (for mechanical installation or a replacement device), the inner end position can be adjusted by turning the friction clutch between the motor and the potentiometer. The outer end position can only by changed by connecting a laptop and a terminal programme. Checking the limit switch function of the EVK 1. Remove the cover of the EVK electronic unit and move the slide "to the strip
centre" or "to the strip edge" by using button S31 and S32 (previous selection S4/2 for manual operation); LED H6 (3) signals "ready to move" or "not in end position".
When it is in the "end position, inner" or "end position, outer" LED H6 goes out and the slide can only move in the opposite direction.
The inner end position is determined by the potentiometer voltage and it can be changed as follows: 1. Drive the slide to the inner position and measure the actual position value at test
socket W. The slide stops at 0 V DC.
2. The limit switch position can now be changed to the desired position by turning the friction clutch between the motor and the potentiometer.
When changing the inner end position the value for the outer end position is also changed. This is to be checked if necessary. The outer value is determined according to the EVK stroke with a scaling value of 1V/100 mm (e.g. EVK600 should display 6 V at the outer end position). The outer end position is factory-set with a scale of 1 V/100 mm. A software-controlled alteration using a laptop is possible, but not necessary for plant operation. In addition, the associated control electronics also offers the possibility of electronically limiting the stroke of the positioning device via the motor controller (e.g. to mask the edges of transfer tables).

EMG Automation GmbH BA_EVK_EVK2-CP_EVM2-CP_LIC_01_en 23
Operation
Operation mode preselection The base board EVK2.11 can be used in combination with the following subprints: 1. EVK2.12 (as electronics for EVM) 2. EVK2.13 (input of an installed SSI stroke transducer), 3. EVK2.14 (connection for 2 analogue sensors with 10 V including external feed of
the supply voltages (e.g. R42D12 assembled on EVK slide) 4. EVK2.15 (connection for 2 analogue sensors with internal 12 V DC supply: US
sensors with 9 V signal output) The various modes of operation are to be set according to the following table: Overview of function switch S2 DIP switch Meaning Notes
S2/1 S2/2 S2/3 S2/4
ON OFF EVM operation; receiver pair evaluation, 2-fold
ON SSI encoder The actual value from the SSI position sensor (with an absolute accuracy of 1/10mm) is used as the actual position value instead of the value from the internal rotary position encoder (potentiometer). This value is transferred via the CAN bus and it is applicable for positioning and end position monitoring. (OFF = int. stroke transducer)
OFF ON EVK operation with input from two analogue sensors via EVK2.14 / EVK2.15
OFF OFF EVK operation including input from an additional analogue sensor via EVK2.14 / EVK2.15
ON Software filter active
PT1 links for the photocell signals and the internal stroke sensor can be activated
"Position" and "locate edge" amplification The basic amplification for the "position" mode is set directly on the sensor positioning device. The software on the EVK2.11 board includes an internal test programme for this purpose, which is set as follows: 1. Select the test programme via function switches S4/3 or S4/4 (standard operation
position 0). 2. Alternating between switching position S4/3 (100 mm) and S4/4 (150 mm) drives
the sensor positioning device between two positions. The degree of amplification can then be aligned using potentiometer R62 to
prevent the positioning device overshooting the selected position. 3. Insert a specimen strip into the measuring area in a strip pass level for the "locate
edge" mode. 4. Select the test programme via function switch S4/1 (standard operation position
0). 5. Moving the material sample causes the positioning device to follow the lateral
movements. The degree of amplification is to be adjusted when doing this using potentiometer R61 on the electronic unit EVK2.11.
In parallel to setting the degree of amplification on the EVK it is also possible to implement a setting via the digital control amplifier. The respective configuration is to be inferred from the system description for the overall control unit.

CAN-Bus communication
CAN bus addressing 1. Use the dip switches S50 and/or S51 to set the address on the CAN Bus network.
Switch S50 here stands for the "Low Byte" and switch S51 stands for the "High Byte". By default the first sensor positioning device in a CAN network is programmed by EMG with the base address "04" hex. When using a second device the address "05" hex is programmed (e.g. for strip centre guiding with two EVKs). The addresses of other positioning devices (e.g. for tack weld alignment) are to be inferred from the operating manual or circuit diagram.
2. Jumper J9 is to be inserted for the last consumer on the CAN network according to the circuit diagram and wiring (visible if no cable appears from terminal strip X33) in order to activate the terminating resistor of 120 .
CAN-Bus transfer rate Use DIL switch S3 to set the transfer rate. This is determined during planning and is dependent, among other things, on the overall cable length and number of users in the CAN network. Alterations and deviations from the factory settings are listed in the operating manual for the overall system. Setting the transfer rate using switch S3.
