Ultrasound edge sensor FX 5030, FX 5060, FX 5100

1. Safety 1.1 Explanation of symbols 1.2 Intended usage

➜ jobs to be performed important information and instructions The E+L ultrasound sensor is constructed according to state-of-theart 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.

1.3 Operating manual

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

1.4 Safety instructions

Never touch the edges of running webs. Never open the transmitter or receiver housing when the edge sensor is switched on. High voltage!

2. Type overview

Types FX 5030 and FX 5100 differ only in the distance between the transmitter and receiver (usable area). Type FX 5030 FX 5060 FX 5100

Usable area < 30 mm < 60 mm < 124 mm

3. Function 3.1 Purpose

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

3.2 Design

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 are transmitted in the air to the receiver elements opposite. Depending on how much of the transmitter element is covered by the web, more or less sound energy will reach the receiver element opposite. This energy is converted into a signal voltage and then a digital value. The microcontroller determines which pair of elements is currently active depending on the web position. The signals from the individual receiver elements are converted into a output value proportional to the web edge position and transmitted to the CAN bus. This output value can be used e.g. to activate a digital controller. At the same time, the actual web edge position in the measuring range is displayed on a row of LEDs. If the LED beside the row of LEDs lights up green, the edge sensor is signalling that it is ready for operation. If it lights up red, it is indicating a fault.

The edge sensor measuring range is ±10 mm and is resolved in 1229 units. In this range, the edge sensor provides a position value corresponding to the location of the web edge.

Measuring range ±10 mm

The zero position is usually in the center of the measuring range. It can be offset in conjunction with a digital controller.

Web Zero position

4. Assembly

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

Threads M5

The level of the web between the transmitter and receiver in relation to the center may fluctuate by the following: FX 5030 < ±15 mm FX 5060 < ±30 mm FX 5100 < ±62 mm The accuracy of the edge sensor cannot be guaranteed outwith these ranges. During operation, the web must not touch either the transmitter or the receiver. Air turbulence due to temperature fluctuations in the edge sensor scanning area may impair the measuring result and for this reason must be avoided.

5. Installation

➜ Protect signal leads and run apart from heavy current-carrying leads. ➜ Tighten the union nuts. These ensure that the edge sensor housing 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 connecting the edge sensor housing to the machine frame.

6. Commissioning

On compact units, no adjustment to the edge sensor is needed on first-time commissioning. If you have ordered control elements separately and wish to link them up yourself in a functioning control loop or if the edge sensor is supplied not ready installed, you must check/set the group and unit numbers on the edge sensor. The group number depends on the digital controller (identical to the group number of the web guider to which 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 system ➜ Set the controller to "center position" mode.

Device number 2 Group number 0

➜ Press the "GRP" and "DEV" buttons on the edge sensor at the same time. After about 6 seconds the group and unit numbers on the LED display will start to flash. After approx. a further 20 seconds the edge sensor switches into setup mode. The LEDs stop flashing and stay on permanently and the group number (GRP button) and unit number (DEV) can be changed. If the "GRP" and "DEV" buttons are not pressed for longer than 1 minute, the group and unit numbers are stored and setup mode exited.

7. Operation

With the help of the row of LEDs on the receiver, the edge sensor can be manually positioned at the web edge.

7.1 Positioning the edge sensor

➜ 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 mode 0). In display mode 1, LEDs 0 to 7 are illuminated, see fig. below.

Display mode 0 (Standard) LEDs 7 and 1 are on

Display mode 1 LEDs 0 and 7 are on

Web edge set position

- If the web is not at its set position or no web is available, position the edge sensor so that the center of the scanning range coincides with the web edge set position.

8. Settings and error messages

In setup mode, setup parameters may be displayed and, to a certain extent, changed. To enter edge sensor setup mode, a command station DO ...., a digital controller DC 55.. or operator panel RT .... are required. 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 indicates the standard settings, Min and Max are the permissible limit values in each case. The Access field shows whether a parameter may only be read (R) or read and written (R/W). The Description field explains the parameter function.

9. Maintenance

Maintenance work should only be performed when the processing machine is switched off. ➜ Depending on the ambient conditions, the transmitter and receiver elements may have to be blow cleaned. The air pressure must not exceed 6 bar. The four transmitter and receiver elements are sealed in a flexible plastic support and must not be exposed to any mechanical pressure (e.g. finger touch).
