1 Safety

1.1 General risk potential

The Laser Measuring Device LE-200 Interbus-S cannot be operated independently, but is installed as part of an overall system usually consisting of several interacting components. For this reason, the laser measuring device is not equipped directly with a protective device.

Warning

The corresponding measures must be taken in order to avoid person and property damages.

However, different error reports can be read out via the status word. The error reports are classified over a malfunction code (see page 27). It is therefore essential to integrate the malfunction code into your own safety system via the evaluation software (e.g. a PLC).

All persons responsible for the assembly, start-up and operation of the device must

• be suitably qualified

• adhere strictly to this operating manual.

Your safety and the safety of your equipment depends on this!

1.2 Safety information

This operating manual contains information which must be observed in the interests of your own personal safety and that of your equipment. The safety hints are emphasized by a warning triangle and classified according to the degree of danger as follows:

Warning

means that failure to take the relevant safety precautions can lead to serious damage to property or injuries.

Note

refers to important information and features of the product, plus tips on its application.

Safety

1.2.1 Hints on installation

Since the Laser Measuring Device is normally used as part of a larger system, these hints are merely intended as a guide for integrating the device safely into its environment.

Warning

• During the operation of the Laser Measuring Device it isn't allowed to interrupt the laser beam. If it comes nevertheless to an interruption, at the restart of the automatic operation mode first the validity (plausibility) of the measured value has to be checked.

• Precautionary measures must be taken to allow an interrupted program to be properly resumed following a voltage drop or failure. Dangerous operating conditions must not be permitted to arise even for short periods. If necessary, an "EMERGENCY STOP" must be forced.

• EMERGENCY STOP devices according to EN 60204/IEC 204 (VDE 0113) must remain operational in all operating modes of the programmable controller. The release of the EMERGENCY STOP devices must not trigger an uncontrolled or undefined reactivation of the equipment.

• The safety and accident prevention regulations applicable to the specific application must be observed.

• In the case of permanently installed plants or systems without an all-pole mains switch and/or fuses, one of these devices must be installed accordingly and the equipment connected to a PE conductor.

• In the case of 24 V supplies, make sure the extra-low voltage is reliably disconnected. Only use power supply units manufactured to the standards IEC 364 - 4 - 41 / HD 384.04.41 (VDE 0100 Part 410).

• Fluctuations or deviations of the supply voltage from the nominal value must not exceed the tolerance limits stated in the specifications, otherwise operational failures and dangerous states in the electrical assemblies cannot be ruled out.

• Connecting and signal wires must be installed in such a way as to prevent the automation functions from being hampered by inductive and capacitive interference.

• The units of the automation system and their operating elements must be installed in such a way as to ensure adequate protection against accidental actuation.

• In order to prevent a wire or strand breakage on the signal side from causing undefined states in the programmable controller, suitable hardware and software safety precautions must be taken with regard to the I/O interface.

Safety

1.2.1.1 General interference suppression measures

• Lay the (shielded) connecting cable to the device at a sufficient distance or in a separate room from any power cables which are subject to interference. Otherwise the data transmission of the measured value can be interfered.

• To ensure reliable data transmission, use fully shielded cables and make sure they are well earthed. For differential data transfer (RS422, RS485 etc.), twisted-pair wires must be used in addition.

• Use a minimum cable cross-section of 0.22 mm

for data transfer purposes.

• Use a minimum earthing cable (machine base) cross-section of 10 mm

in order to avoid equipotential currents across the shield. Make sure the resistance of the earthing cable is much lower than that of the shield.

• Avoid crossing cables where possible. If unavoidable, only cross them at right-angles.

• Ensure continuous wiring of the shield and a large contact area on special shield

clampings or cable screw glands, see Figure 1 point (A) and (B).

1.3 Intended purpose

The measuring system is used for recording linear movements and processing the measured data for a downstream control system with a INTERBUS-S Field Bus interface according to DIN 19258.

The classification of the measuring system is defined according to the profile K3. At this the laser data uses 2-word addresses for IN-data and 2-word addresses for OUTdata in the Master.

Particularly the measuring system is designed for the use of distance measurements for the detection of the position and positioning of:

! High-bay storage devices and lifting gears ! Crane systems ! Side-tracking skates and truck storage vehicles ! Transfer machines

Warning

Switch off the voltage supply before carrying out wiring work or opening and closing electrical connections!

Short-circuits, voltage peaks, etc. can cause operating failures and uncontrolled operating states, as well as serious personal injuries and damage to property.

Check all electrical connections before switching on the system!

Incorrectly wired connections can cause operating failures, while wrong connections can lead to serious personal injuries and damage to property.

Mechanical or electrical modifications to the measuring systems are prohibited for safety reasons!

In particular the following uses are forbidden

- operation in areas where interruption of the laser beam, e.g. by covering the

laser lens opening, can lead to equipment damage or injury to personnel

- in environments, in which strong rain, snow, fog, steams or direct insolations

etc. can influence the laser beam intensity negatively

- operation in rooms with explosive atmospheres

- operation for medical purposes

With use-purposes larger 125m measuring length, a special reflector must to be used! (see chapter "Accessories", page 37)

Warning

Laser Light

Do not stare into the beam

Laser Class 2

DIN EN 60825-1: 2003-10

Complies with 21 CFR 1040.10 and

1040.11 except for deviations pursuant to laser notice No. 50, July 2001

P max = 1 mW, = 670 nm

• In the case of Class 2 laser devices, the eye is not endangered if the exposure of

the laser radiation is very short (up to 0.25 s) and accidental. For this reason, devices of this class can be used without additional protective measures, provided for the application it is not necessary to look into the laser beam deliberately for longer periods, i.e. 0.25 s, or to look repeatedly into the laser beam itself or the specular reflected beam.

The existence of the blinking reflex for the protection of the eyes may not be assumed. Therefore the eyes should be closed consciously, or the head should be turned away immediately!

• The device must be installed in such a way that the exposure of persons to the laser beam can only happen accidentally.

• The laser beam may only extend as far as is necessary for the range measurement. The beam must be limited at the end of the useful range by a diffusely reflecting target area in such a way as to minimize the danger from direct or diffuse reflection. For this purpose, you should use the TR-Electronic reflecting foil supplied with the device.

• The area outside the operating range where the unshielded laser beam falls should be limited as far as possible and should remain out of bounds, particularly in the area above and below eye level.

• Observe the legal and local regulations applicable to the operation of laser units.

Note

The start-up, operating and programming instructions contained in this manual are mandatory.

General Description

Page 12 of 37 TR - ELE - BA - GB - 0008 - 06 14.12.2007

2 General Description

The laser measuring devices of the series LE are optical sensors, with which larger distances can be measured without contact and serviceable for controller. The measuring system consists of the real measuring device with laser light source, receiving optics, electronic evaluation and data interface as well as a reflector. The device sends out a modulated light beam which is reflected by the reflector. From the phase difference of the sent and received light beam the distance is measured 1000 times per second. Thus the LE is suitable also directly for the position feedback in controller loops.

According to the requirements the laser distance measuring devices of the series LE-200 Interbus-S are configured either directly over the Interbus-S or with the PCprogramming software "TRWinProg".

4 Assembly instructions

The adjustment of the laser measuring device in the vertical plain is carried out via four studs (A) in the mounting plate. The adjustment in the horizontal plane can be made by four hexagon bolts (B). It has to be taken into account that the screw diameter is approx. 1-2 mm smaller than the through bore of the mounting plate. Exact dimensional properties are on the dimensional drawing in the rear part of the document.

Figure 2: Mechanical adjustment possibilities

4.1 Aligning of the laser light spot to the reflector / foil inclination

The measuring device or reflector is attached to the moving object and the reflector/sensor to the fixed remote station in such a way that the reflector always remains within the visual field of the sensor. This can be done using the light spot of the laser diode, which is still clearly visible on the reflecting foil even at long distance. When aligning the laser measuring device, the user may need to take measures to ensure that it can be mechanically adjusted. The size of the reflecting foil must be such that the light spot cannot be displaced from the reflector by vibrations. Since with an increasing distance the light spot gets larger and larger, the edge areas of the foil also have to be avoided. The device comes with a reflecting foil measuring 20 x 20 [cm], but other sizes can be ordered on request.

Note

Reflecting foils by other manufacturers should not be used under any circumstances, as all the information in the "Specifications" chapter refers to the foil already supplied with the device.

Assembly instructions

14.12.2007 TR - ELE - BA - GB - 0008 - 06 Page 15 of 37

Procedure:

•

Figure 3: Detection of the surface reflectivity:

- At first attaching the reflector foil flatly and drive plant on minimal

distance Laser – Foil.

- Centering paper (C) in front of the laser optics so, that the laser beam

can unhinderedly emerge by an approx. 2 cm hole. Now, the interfering signal (B) should get visible on the paper (C). To the better location of the interfering signal (B) the reflector foil can be moved also a little. Here it is valid: angle of incidence = angle of reflection

•

Figure 4: Transmitting away the surface reflectivity:

- Rotate the reflector foil in the Y- or in the Z-axis so, that the interference

signal (B) always is outside the laser lens. Nevertheless keeping the inclination of the reflector foil as low as possible to minimize measuring errors caused by misalignments in the procedure movement. For example, if the light spot drifts on the reflector foil around, small differences arise as a result of the oblique position.

- Fix reflector foil

4.2 Parallel operation of laser linear paths

It has to be taken care in the parallel operation of laser linear paths that a minimum distance of 1 m is kept. The reflector foil inclination must be made in such a way that the surface reflectivity (see arrows) points not into the other laser linear path. The alignment is carried out as described in chapter 4 / 4.1.

5.3 Interbus-S - Interface

The Laser Measuring Device LE-200 with INTERBUS-S interface is designed as a remote bus module with 32 I/O data. This makes it easy to integrate in the bus ring in the same way as a PHOENIX-CONTACT bus terminal. To ensure that the protocol meets INTERBUS-S requirements, an SUPI (serial microprocessor interface) is integrated between the LE-200 and the INTERBUS-S. The SUPI is an INTERBUS-S protocol chip developed by PHOENIX-CONTACT which carries out the following functions:

• BUS interfacing: Directions of reception and transmission

• CRC check

• Preset

• Transfer protocol etc.

The classification of the Laser Measuring Device is defined after the profile K3 and has the Ident-No. 55 dec. According to this profile the Laser Measuring Device delivers 32 bits of process data. These 32 bits contain a 25-bit position actual value and a 7 bit status bit and control bits. The position actual value of the laser is coded binary and right aligned in the bits 0 - 24 of the process data word. Bits 25 – 31 contain the status bit and control bits. They are fixed in this profile class. When all control bits are set to 0 and the OPERATION condition is displayed on the status bits, the laser outputs a valid value for bits 0 to 24.

5.3.1 Mapping of Laser Data in the Master (Controller)

In the master, the laser data uses two-word addresses for IN-data and two-word addresses for OUT-data. The position of the data in the controller depends on the physical or logical position of the laser within the ring. For detailed information, refer to the manual of the master (controller) used. The laser should be considered to be a PHOENIX I/O bus terminal and the system processes it as such.

Page 26 of 37 TR - ELE - BA - GB - 0008 - 06 14.12.2007

6 Configuration / Parameter setting via the Interbus-S master

The configuration of the laser occurs alternatively via the configuration software of the Interbus-S - master or via the TRWinProg-software. With a download of the control parameters the parameters, which were configured via the TRWinProg-software, will be overwritten by the control. In this instruction only the configuration via the Interbus-S - master is described. The PC program TRWinProg is described in an instruction of its own.

6.1 Parameter data

The parameter data can be transferred via the bits 0 to 24 of the process out data channel of the master to the laser. To this the laser must be set to the parameterization state. This is achieved by outputting a parameter number unequal to zero on bits 9 to 12 of the control word (bits 25 to 28 of the process out data channel).

The laser switches over to the "parameterization" state and indicates the successful transmission of the parameter with the return of the corresponding parameter number.

The new parameter takes effect after the user has set the laser to the ’operation’ state with the ’enable operation’ device control command. If it was not possible for the parameter to take effect, the laser switches over to the ’malfunction’ state –after the user has sent the ’enable operation’ device control command - and outputs a malfunction number on bits 9 to 12 of the status word (bit 25 to 28 of the process data channel).

1): You must make sure that when a parameter is transmitted, the same parameter number as that which has already been acknowledged by the laser is not sent. The repeated transmission of the same parameter is not valid without first leaving the "parameterization" state.

The parameter number must be consistent. To transmit several parameters, repeat steps 4 to 6.

When transmitting a parameter, make sure that the parameter number is not output before the parameter.

When invalid or inconsistent parameters are sent, the laser goes into the "malfunction" state when trying to enable operation.

An illegal parameter value (5) was programmed into line 2 for the parameter "resolution" which at first is accepted by the laser device and remains in the operational state "parameterization" furthermore.

In line 7, the counting direction of the laser was then programmed (increasing to the Laser).

In line 10, after finished programming the device control command "enable operation" was sent to the laser device.

The programmed values are checked only now (line 11) for their validity and the laser passes into the state "malfunction". The position value is output on the process data channel. This value is possibly faulty depending on which programmed parameter was illegal.

7 Causes of Faults and Remedies

The fault causes are defined according to the malfunction code (see page 27). For the resetting of the malfunction code, at first the error must be eliminated. After this the device control command "Enable Operation" must be sent to the laser. If the switching input was adjusted via the TRWinProg-software for error resetting, the error can be acknowledged also about the external switching input.

Malfunction Code

Cause Remedy

0001 Invalid parameters from the host

Invalid parameter data, a parameter range error is available.

Check all programmed parameters after valid ranges of values (see "Parameter overview", page 26 and "Parameter description", starting from page 30).

0011 Memory error

Hardware error

If the error occurs at repeated service type, the device must be replaced.

1001 Intensity warning

The device determined an intensity of < 12%.

This message is only a warning and means that the measuring system optics, or the reflecting foil is to be cleaned. However, the device operates error-freely furthermore.

1010 Laser diode switched off

The bit is set, if the laser diode was switched off over the bus, or the switching input.

Serves only for information purposes.

1100 Intensity error

The device checks the intensity of the received laser signal continuously, it was detected a belowminimum intensity.

1. Clean measuring system optics

2. Clean reflecting foil

3. Rule out an interruption of the laser beam

If the possibility of soiling or interruption of the laser signal can be ruled out, the device must be replaced.

1101 Speed-check

The adjusted speed level was exceeded.

Serves only for information purposes, whether the adjusted speed level was exceeded. (Function see chapter 5.2, page 20 and chapter 6.2.7, page 31).

1110 Device temperature

The temperature has exceeded or fallen short of the range of 0 - 50°C in the housing of the device.

Appropriate measures must be taken to prevent the device from overheating or undercooling.

1111 Plausibility warning

The plausibility of the measured value couldn't be guaranteed any more.

This message is a warning and means that possibly corresponding measures must be taken, so that no system components will be damaged.
