Ultrasound edge sensor FX 5030, FX 5060, FX 5100

1. Safety1.1 Explanation of symbols

jobs to be performedimportant information and instructions

The E+L ultrasound sensor is constructed according to state-of-the-art technology and is used for contact-free web edge scanning.The ultrasound edge sensor should only be used- in perfect technical condition,- for use as intended,- in accordance with the operating instructions.

Please keep the above in a safe place and make accessible to per-sonnel at all times.The manual is part of the package supplied and should be read care-fully prior to assembly, operation and maintenance.

Never touch the edges of running webs.

Never open the transmitter or receiver housing when the edge sen-sor is switched on. High voltage!

Types FX 5030 and FX 5100 differ only in the distance between thetransmitter and receiver (usable area).

Type Usable areaFX 5030 < 30 mmFX 5060 < 60 mmFX 5100 < 124 mm

The ultrasound sensor scans the web edges of sound absorbing ma-terials such as paper, film or tightly knitted fabrics without touching. Itis especially suitable for light-sensitive transparent materials whereoptical edge sensors can only be used to a limited extent.

The edge sensor consists of:- a transmitter with four transmitting elements- a receiver with four receiving elements- a connecting section

3.3 Operating principle The edge sensor works on a sound-voltage conversion principle.The transmitter elements produce ultra-sound pulses which aretransmitted in the air to the receiver elements opposite. Dependingon how much of the transmitter element is covered by the web, moreor less sound energy will reach the receiver element opposite. Thisenergy is converted into a signal voltage and then a digital value.The microcontroller determines which pair of elements is currentlyactive depending on the web position. The signals from the individualreceiver elements are converted into a output value proportional tothe web edge position and transmitted to the CAN bus. This outputvalue can be used e.g. to activate a digital controller. At the sametime, the actual web edge position in the measuring range is display-ed on a row of LEDs.If the LED beside the row of LEDs lights up green, the edge sensoris signalling that it is ready for operation. If it lights up red, it is indica-ting a fault.

3.4 Edge sensor measuringrange

The edge sensor measuring range is 10 mm and is resolved in 1229units. In this range, the edge sensor provides a position value corre-sponding to the location of the web edge.The zero position is usually in the center of the measuring range. It canbe offset in conjunction with a digital controller.

Two M 5 threads each are featured on the transmitter and receiverhousing for assembly purposes. Mount the edge sensor so that the web runs at a angle of 90 to it.

The level of the web between the transmitter and receiver in relationto the center may fluctuate by the following:FX 5030 < 15 mmFX 5060 < 30 mmFX 5100 < 62 mmThe accuracy of the edge sensor cannot be guaranteed outwith the-se ranges. During operation, the web must not touch either the trans-mitter or the receiver.

Air turbulence due to temperature fluctuations in the edge sensorscanning area may impair the measuring result and for this reasonmust be avoided.

5. Installation Protect signal leads and run apart from heavy current-carryingleads. Tighten the union nuts. These ensure that the edge sensor hou-

sing and the signal lead insulation are conductively connected. Secure the signal lead with a cable clamp.

Subject to heavy static charging of the web, we recommend con-necting the edge sensor housing to the machine frame.

On compact units, no adjustment to the edge sensor is needed onfirst-time commissioning.

If you have ordered control elements separately and wish to linkthem up yourself in a functioning control loop or if the edge sensor issupplied not ready installed, you must check/set the group and unitnumbers on the edge sensor. The group number depends on the di-gital controller (identical to the group number of the web guider towhich it belongs).Edge sensor on right in web direction of travel, unit number "1"Edge sensor on left in web direction of travel, unit number "2"

Direction of web travel = Processing direction for the entire sy-stem

Set the controller to "center position" mode. Press the "GRP" and "DEV" buttons on the edge sensor at the

same time. After about 6 seconds the group and unit numbers onthe LED display will start to flash. After approx. a further 20 se-conds the edge sensor switches into setup mode. The LEDs stopflashing and stay on permanently and the group number (GRPbutton) and unit number (DEV) can be changed.If the "GRP" and "DEV" buttons are not pressed for longer than1 minute, the group and unit numbers are stored and setup modeexited.

7. Operation With the help of the row of LEDs on the receiver, the edge sensorcan be manually positioned at the web edge. Set the web offset on the digital controller to "0". Position the edge sensor manually:- If the web is at its set position, place the edge sensor at the web

so that only the two middle LEDs, 7 and 1 are on (display mode0). In display mode 1, LEDs 0 to 7 are illuminated, see fig. below.

In setup mode, setup parameters may be displayed and, to a certainextent, changed. To enter edge sensor setup mode, a command sta-tion DO ...., a digital controller DC 55.. or operator panel RT .... arerequired.The parameter numbers are listed in the Number field of the table,the short form of the error in the Name field. The Default field indica-tes the standard settings, Min and Max are the permissible limit valu-es in each case. The Access field shows whether a parameter mayonly be read (R) or read and written (R/W). The Description field ex-plains the parameter function.

Maintenance work should only be performed when the processingmachine is switched off.

Depending on the ambient conditions, the transmitter and receiverelements may have to be blow cleaned. The air pressure must notexceed 6 bar.The four transmitter and receiver elements are sealed in a flexibleplastic support and must not be exposed to any mechanical pres-sure (e.g. finger touch).

The length of the individual cables must be deducted from the ma-ximum cable length in a CAN network. For one edge sensor itmay be a maximum of 8 m, for two sensors a maximum of 16 m.
