1.1 Getting Started
How to prepare the EDM 35 for use For convenience you have a check list below to be sure that all preparations of the EDM are made before the application. Page references are mentioned so you can easily find the point in question in this manual. If the EDM is received in modules start at point 1, otherwise start at point 6. 1. Select all modules necessary for the application. 2. Set jumpers on the input module and if used also on the excitation output module and/or the analogue output module. 3. Insert all modules according to the drawing printed on the module: Power supply first (then from right to left). Mount blind covers in non-used slots. 4. Fill out the label on the main unit and the shipping box with missing information (ordering key for system, power supply, inputand output modules and ranges). Easy access to this information might help you later. 5. Insert engineering unit in the front cover and mount this. 6. The program needs information about the actual input range. Check input range selection and change if necessary. 7. Program panel meter to suit the application.

1.2 Overall Description
The EDM series 35 is based on a modular concept consisting of a main unit and plug-in modules. The concept provides the meter with high flexibility and versatility. The offer of input-, output- and power supply modules makes it possible to configure the meter to suit most applications. Furthermore, the modular concept ensures that the stock costs are minimized.

1.3 Features

The main features of the EDM series 35 are: - Modularity - Continuous measurement and monitoring of the analog signal of the input variable - Continuous monitoring of the measured value for exceeding the programmed setpoint values - Setpoints individually programmable: Value, hysteresis, high/low alarm, time delay - Separate programming of each output relay: energized/deenergized and status in overflow condition - Additional software functions: scaling, data hold and peak/valley - Input modules for measuring voltage (AC or DC), current (AC or DC), resistance, temperature (Pt 100 or thermocouple J or K), frequency or revolutions per minute - Output modules with 1 or 2 relays or with analogue output (4 - 20 mA, 0 - 20 mA, 0 - 10 V) - Power Supply modules for AC or DC supply as well as excitation supply for sensor supply - Interface to Carlo Gavazzis Dupline Field and Installation Bus The large variety of input signals of both electrical and industrial process variables make the EDM an extremely versatile instrument suitable for many applications. The characteristics of the instrument are complemented by its easy programming and configuration in accordance with the application. 3

2.1 Modules

2.1.1 Common description The modules are parted into 3 categories: Power supply modules, input modules and output modules. Each module is dedicated to its own function or input variable. To minimize the number of modules many input modules are designed to cover all ranges. If you want to change the input range just press the locking tabs and pull out the module to change a jumper position, reinstall the jumper and reprogram the range selection. If you change the range from low to high level or vice versa it might be necessary for you to use other terminal positions as well. The input modules are available with terminals for program lock to protect against unauthorized admittance.

All modules are easy to plug in - for your information the slot position is marked on the drawing on the rear of the module. 4
2.1.2 Variants 2.1.2.1 Power Supply Modules You will always need the power supply module. These are available for the most common supply voltages. Due to the size of the transformer the power supply module always occupies 2 slots.
2.1.2.2 Input Modules The input modules are divided into the following categories: Voltmeters (AC or DC) Ammeters (AC, DC or 10A AC/DC) Ohmmeters Thermometers (Pt 100, Thermocouple J or K) Frequency - and Tachometers Dupline Analink Interface
For voltmeters, ammeters, ohmmeters, frequency - and tachometers a jumper in the module determines the actual range for the module. Switching from one range to another also means that you are switching from one input circuit to another input circuit. For ammeters 10 A AC/DC the jumper determines whether you are measuring AC current or DC current. The thermometers do not include a jumper - here the range is changed only through the programming. For the Dupline Analink interface module only the channel number has to be coded on two rotary switches. All input modules occupy 1 slot and they are always placed at left (rear view of the main unit). 5

2.1.2.3 Output Modules

The output modules are divided into the following categories: Relay output (1 or 2 relays) Analogue output (4-20 mA, 0-20 mA and 0-10 V) Excitation output (for sensor supply) Depending upon the application you can choose between different output types: An output module with 1 or 2 relays and/or an output module with analogue output where you are able to select the required type of analogue output with the jumpers. The relay output module is always placed at right (rear view of the main unit). With the excitation output module inserted you are able to supply for example sensors which are a part of the application. With a jumper you can select 12 or 24 VDC. This module shares slot #2 with the analogue output module. 2.1.3 Modules and Slot Position

2.2 Main Unit

2.2.1 Description The main unit includes a 3 1/2 digit, 7-segment display with alarm indicators, a motherboard for 1 power supply module and 3 input/output modules, a processing unit and a keyboard. You can use the main unit as a 3 1/2 digit indicator when inserting only a power supply module and an input module. If you extend the system with a relay output module and/or an analogue output module, you have a 3 1/2 digit controller. The main unit is delivered with 1 front cover,1 manual, 2 mounting brackets, 2 gaskets for sealing, 1 set of engineering unit labels and 3 blind covers for unused slots. 2.2.2 Variants The main unit is available in 3 different variants.

A set of engineering unit labels is supplied with the EDM. The engineering unit has to be inserted by the customer.

3.1 Procedure

Before the instrument is ready for use, i.e. before it is ready for the application dependent programming, you have to prepare the instrument physically (engineering unit, modules etc.) - this is described in chapter 3.2 Installation. Before you are connecting the instrument to the mains or the power supply you have to be sure that the right power supply module is used. This is discussed in chapter 3.3 Rated Operational Voltage. You have to check the jumper settings on some of the modules. The range selected must be in accordance with your application. The jumper setting is shown in chapter 3.4 Jumper Setting on Modules. After you have set the jumpers the processing unit must know which range you have selected. This range code has to be entered in the software when the instrument is turned on. Further information will be given to you in chapter 3.5 Input Range Selection.

3.2 Installation

First, if desired, you insert the engineering unit (3). You can choose a unit from the set of engineering unit labels.
Then you mount the front panel (2) on the instrument remember to seal with the enclosed gasket (the largest of the two enclosed). Place the remaining gasket round the body of the instrument and slide instrument into the panel aperture. To optimize the tightness be sure that the panel cut-out is completed and deburred. Be also aware that a too thin panel may distort and not provide sufficiant sealing. Fasten the instrument with the two brackets (1). 9
3 Installation & O p e r a t i o n s b e f o re U s e
If you later want to replace the engineering unit (3), you insert a screwdriver into the lateral slot in the front panel and turn (be careful!) the screwdriver as shown until the front panel has been completely removed. Replace the engineering unit. You can find the panel cutout and the mechanical dimensions in chapter 7.3 Mechanical Dimensions.
3.3 Rated Operational Voltage
Before you switch on the instrument, make sure that the supply voltage corresponds to the rated operational voltage indicated on the power supply module.
Rated operational voltage
Caution!! Since the input circuitry is not galvanically isolated, the potential of the measured variable will be present on all connections to the unit (i.e. HOLD input). This is important specially when you are measuring line voltage and current.
3.4 Jumper Setting on Modules
As some modules are designed to cover several ranges it can be necessary for you to select the required range by moving an internal jumper. The major part of the input modules, the excitation output module and the analogue output module have this possibility for range selection. On the following pages the jumper setting is shown for the modules: 3.4.1 3.4.2 3.4.3 3.4.4 3.4.5 3.4.6 Voltmeters Ammeters Ohmmeters Frequency - and tachometers Dupline Analink Interface module Output modules
Note! Always remember to turn off the power supply before you plug in or pull out the modules. 10

3.5 Input Range Selection
When you have selected the range on the input module (according to 3.4 Jumper Setting on Modules) you have to update or check the programming to be sure that the programmed range code corresponds to the range selected with the jumpers on the module. This is accomplished in calibration mode. Other functions in calibration mode are discussed in chapter 8.1 Calibration Mode. To change or check the programmed range follow the description below. 1. Press S and w simultaneously and switch on the unit. The. Release the keys. The display shows. S and the display now

S , v and w control the display. The normal function of the display is to indicate the measured input variable. The following lines describe how you can use these for selecting information on the display during daily operation. 17
The flowchart shows how you get access to the different modes of operation.

Press 4.2.1.7 Hold Function The Hold function is standard for all versions and is located on the terminals of the power supply module. By short-circuiting the Hold input, the indication on the display is frozen. When the Hold function is active, all other functions operate in normal way. 4.2.1.8 Setpoints The setpoints can operate in four different ways depending on the programming. See the following drawing.

Scaling Operation

4.2.2 Programming Mode

The programming mode allows the user to define the instrument parameters: Password for access to programming Decimal point position Minimum and maximum values of the electrical input range Display span
and for each alarm setpoint: Setpoint High or low alarm levels Hysteresis Time delay Alarm relay normally energized/de-energized State of alarm relay in overflow conditions
Stepping from the programming of one parameter to the programming of the next happens by pressing S. The normal measurement and control functions are not active in programming mode. The alarm outputs are OFF. The analogue output is low. Termination of the programming mode and return to measurement and control mode follows automatically after completion of all programming steps or after 3 minutes without key activation. The display will show for 2 seconds.
4.2.2.1 Access to Programming Mode 1. Press and hold S ; then press v. Release both immediately.

after the display shows

During this phase the instrument asks for a password between 0 and 199 - the instrument is delivered with the password 0. 2. If the password is not set to zero, press v and/or w until the value (password) is displayed. Press S to enter. If the entered password matches the stored password, the instrument automatically proceeds to the next step - otherwise it returns to measurement and control mode.

4.3 Programming

4.3.1 New Password 1. After you have entered the password the display shows the present value, press S.
After 2 s the stored value of the password is displayed. To retain to pass on to the next selection. 2. To modify the password, press v and/or w until the desired value is displayed; this has to be a number between 0 and 199. Press S to pass on to the next parameter.
A password between 100 and 199 gives direct access to setpoint programming in the following way: Enter programming mode and press S. Then you will automatically jump directly to setpoint programming. After the setpoint programming the programming mode is terminated. 4.3.2 Decimal Point Selection Decimal point selection is relative to the displayed value. 1. After selection of the password the display will show display by a steady light as. for 2 s.
The current position of the decimal point is then indicated on the 2. Change the position of the decimal point using v (shift to left) and/or w (shift to right). Press S to enter and pass on to next.
4.3.3 Electrical Input Range (HiE and LoE) This feature allows you to define an electrical input range different from the standard range. For example, for EDM with full-scale 20 mA (19.99 mA), it is possible to select an electrical input range from 4.00 mA to 19.99 mA by proceeding as follows: 1. After programming the decimal point the display shows seconds signifying the maximum of the electrical input range. The HiE value stored in the memory is shown on the display, for example. S to pass on to next parameter. To retain the value shown, press for 2
2. To select a new value of HiE, press v and/or w until the desired
value is displayed, for example

. Press

S to accept. for 2 s
3. After programming the HiE the display shows signifying the minimum of the electrical input range.
The LoE value stored in the memory is then shown on the display. To modify the LoE value proceed as described for the HiE value, but select the value 4.00 (according to the example). Press S to accept the value and pass on to the next parameter.
Note! LoE and HiE values are shown in the same unit of measurement as the input module range. 4.3.4 Display Span (Hi and Lo) This allows you to define the display span (in engineering units) corresponding to the previously defined electrical input range. For example EDM 20 mA Programmed electrical input range: 4.00 to 19.99 [mA] Programmed display span: 0.00 to 8.00 [bar] Lo: Displayed value corresponding to minimum of the input range (LoE). Hi: Displayed value corresponding to maximum of the input range (HiE).
The display can be programmed within the instrument read-out range indicated in the technical data tables. Since the link between the electrical and the displayed value is completely adjustable/variable, it is possible to correlate a minimum electrical value to a maximum display value, and vice versa (scale inversion). The best resolution is achieved when HiE - LoE Hi - Lo 1 for

1. After selecting the electrical input range, the display shows 2 s, signifying the maximum of the display span. The display then shows the Hi value stored in the memory. Press S current value. to retain the
2. To select a new Hi value, press v value is displayed. Press S

3. After entering the Hi value the display shows
the minimum of the display span. The display shows the current value of Lo. To change or retain the Lo value proceed as described for Hi. After the entering of the value with on to the next parameter. S the instrument passes
4.3.5 Alarm Setpoint(s) - Controller
The EDM automatically senses if a relay output module is installed in the instrument, and programming mode proceeds to entry of the data relating to the setpoints. If no relay output module is installed, programming mode will be terminated after the display span programming. Note! The setpoint is relative to the display span, and not to the electrical input range.
4.3.5.1 Setpoint 1. After programming the display span the display shows indicating that the current programming concerns setpoint 1. The display will then show the stored setpoint value. To retain the value shown, press S. 2. To select a new value for SP1, press desired value is displayed. Press next parameter. S v and/or w until the for 2 s,

1. GENERAL INFORMATION

1.1. General description of the safety light curtains
The safety light curtains of the SB4-E/B/M/N series, are optoelectronic multibeam devices that can be used to protect working area that, in presence of machines, robots, and automatic systems in general, can become dangerous for operators that get in touch, even accidentally, with moving parts. The light curtains of the SB4-E/B/M/N series are Type 4 intrinsic safety systems used as accident-prevention protection devices and are manufactured in accordance with the international Standards in force for safety, in particular:

IEC 61496-1: 2004

Safety of machinery: electro-sensitive protective equipment. Part 1: General requirements and tests. Safety of machinery: electro-sensitive protective equipment. Particular requirements for equipment using active optoelectronic protective devices.

CEI IEC 61496-2: 1997

The device, consisting in one emitting and one receiving units housed inside strong aluminium profiles, generates an infrared beam array that detects any opaque object positioned within the light curtain detection field. The emitting and the receiving units are equipped with the command and control functions. The connections are made through a M12 connector located in the lower side of the profile. The synchronisation between the emitter and the receiver takes place optically, i.e. no electrical connection between the two units is required. The microprocessors guarantee the check and the management of the beams that are sent and received through the units: the microprocessors through some LEDs inform the operator about the general conditions of the light curtain and about eventual faults (see section 7 Diagnostic functions). 1
During installation, two yellow LEDs facilitate the alignment of both units (see section 5 Alignment procedures). As soon as an object, a limb or the operators body accidentally interrupts the beams sent by the emitter, the receiver immediately opens the OSSD output and blocks the machine (if correctly connected to the OSSD). Note: The following abbreviations, defined by the Standards in force, will be used in this manual: AOPD Active opto-electronic protective device ESPE Electro-sensible protective equipment OSSD Output signal switching device (switching output) TX Emission device RX Receiving device Some parts or sections of this manual containing important information for the operator are preceded by a note: Notes and detailed descriptions about particular characteristics of the safety devices in order to better explain their functioning; special instructions regarding the installation process. The information provided in the paragraphs following this symbol is very important for safety and may prevent accidents. Always read this information accurately and carefully follow the advice to the letter. This manual contains all the information necessary for the selection and operation of the safety devices. However, specialised knowledge not included in this technical description is required for the planning and implementation of a safety light curtain on a power-driven machine. As the required knowledge may not be completely included in this manual, we suggest the customer to contact CARLO GAVAZZI Controls Sales Technical Service for any necessary information relative to the functioning of the SB4-E/B/M/N series light curtains and the safety rules that regulate the correct installation (see section 8 Checks and periodical maintenance).

1.2. New features with respect to the SB series
With respect to the basic SB series, the SB4-E/B/M/N safety light curtains present the following new features: the entire series is composed of Type 4 safety light devices introduction of the EDM function on all models availability of models with Floating and Fixed Blanking Cascade configuration possibility of two safety light curtains in master-slave mode SB4-E/B/M/N series does not include models with the Muting function SB4-E/B/M/N series does not include models for body protection. The aforementioned functions have not been implemented in all the models. The following table lists the possible combinations available in the models of the SB4-E/B/M/N* series:
Model EDM Finger Protection EDM Hand Protection Blanking Finger Protection Blanking Hand Protection Cascade&Blanking Finger Protection** Cascade&Blanking Hand Protection** Resolution 14mm 30mm 14mm 30mm 14mm 30mm EDM x x x x x x x x x x x x Blanking Cascade
* please refer to specific section (section 10 List of available models) for the complete list of all the models available with relative order code and description. ** the Blanking function, in the Cascade & Blanking models, is available only in the master unit.
1.3. How to choose the device
There are at least three different main characteristics that should be considered when choosing a safety light curtain: The resolution strictly depending on the part of the body to be protected. R = 14mm 20mm R 40mm Finger protection

Type 4

Hand protection
The resolution of the device is the minimum dimension, which an opaque object must have in order to obscure at least one of the beams that constitute the sensitive area. As shown in Fig.1, the resolution only depends on the geometrical characteristics of the lenses, diameter and distance between centres, and is independent of any environmental and operating conditions of the safety light curtain.
Fig. 1 The resolution value is obtained applying the following formula: R=I+d

Fig. 5 The following formula is used for the calculation of the safety distance: S = K (t1 + t2) + C where:
S = Minimum safety distance in mm. K = Speed of the object, limb or body approaching the dangerous area in mm/sec. t1 = Response time of the ESPE in seconds (see section 9 Technical data) t2 = Machine stopping time in seconds. d = Resolution of the system. C = 8 (d -14) for device with resolution 40mm
Note: The value of K is: 2000 mm/s if the calculated value of S is 500 mm 1600 mm/s if the calculated value of S is > 500 mm If the safety light curtain must be mounted in a horizontal position (Fig.6), the distance between the dangerous area and the most distant optic beam must be equal to the value calculated using the following formula: S = 1600 mm/s (t1 + t2) + 1200 0.4 H where:
S = Minimum safety distance in mm t1 = Response time of the ESPE in seconds (see section 9 Technical data) t2 = Machine stopping time in seconds H = Beam height from ground. This height must always be less than 1000 mm.

Fig. 6

2.2.2. Safety distance variation with Blanking function activated The activation of the Floating Blanking function generates a resolution reduction of the device. Consequent to this reduction, signalled also by the device signalling lamp (see section 6.6 Blanking function), the light curtain has to be repositioned at the right safety distance according to the indications supplied in the previous section and complying with the real device resolution. The folllowing table summarises the resolution variation in all possibile applications:
Declared resolution 14 mm 30 mm
Real resolution with Floating Blanking 1 beam 2 beams 3 beams 21 mm 48 mm 28 mm 66 mm 35 mm 84 mm
2.2.3. Minimum distance from reflecting surface Reflecting surfaces placed near the light beams of the device (over, under or laterally) can cause passive reflections.These reflections can compromise the recognition of an object inside the controlled area (Fig.7)
Fig. 7 However, if the RX receiver detects a secondary beam (reflected by the side-reflecting surface) the object might not be detected, even if the object interrupts the main beam.
It is thus important to position the safety light curtain according to the minimum distance from any reflecting surface. The minimum distance depends on: Operating distance between emitter (TX) and receiver (RX); Maximum opening angle of the light beam sent by the safety light curtain, depending on the type of the device; in particular: - 5 for ESPE Type 4 ( 2.5 as to the optic axis); The graphic in Fig.8 shows the data of the minimum distance.

The ground connection of the two units depends on the electrical protection class to be guaranteed (see section 9 Technical Data for more information). This connection can be carriedout using the mechanical part supplied for ground connection (see Fig.14). Insert the support plate (M4x0.7 mm threaded holes) in one of the two slots visible laterally on the profile. The two pins (M4x14) have to be screwed on the external support hole, leaving the central hole free. We suggest to screw the pins using a Couple included between 2.2 and 2.5 Nm. The Couple guarantees that the pin head passes through the paint allowing the contact with the metal housing. Block the pins using the two M4 self-fixing nuts. Fig. 14 The nuts have to be tightened using a hexagonal CH.7 wrench. The nuts avoid the unscrewing of the pins in presence of strong vibrations. Insert the M4 ring and screw it on the central support hole.
The OSSD1 and OSSD2 safety contacts cannot be connected in series or in parallel, but can be used separately (Fig.15). If one of these configurations is erroneously used, the device enters into the output failure condition (see cap.7 Diagnostic functions). Connect both OSSD to the activating device. The avoided connection of an OSSD to the activating device jeopardises the system safety degree that the light curtain has to control.

5. ALIGNMENT PROCEDURES

The alignment between the emitting and the receiving units is necessary to obtain the correct functioning of the light curtain. The alignment is perfect if the optic axes of the first and the last emitting units beams coincide with the optic axes of the corresponding elements of the receiving unit. Two yellow LED indicators (HIGH ALIGN, LOW ALIGN) facilitate the alignment procedure.
5.1. Correct alignment procedure
When the mechanical installation and the electrical connections have been effected as explained in the previous paragraphs it is possible to carry-out the alignment of the safety light curtain, according to the following procedure: Disconnect the power supply. Press the TEST/START button and keep it pressed (open the contact). Re-connect the power supply. Release the TEST/START button. Check the green LED on the bottom of the TX unit (POWER ON) and the yellow LED (SAFE); if they are ON, the unit is running correctly. Verify that one of the following conditions is present on the RX unit: The green LED on the bottom is ON (POWER ON) and the light of the SAFE/BREAK LED on the top is red (BREAK): nonalignment condition. The green LED on the bottom is ON (POWER ON) and the light of the SAFE/BREAK LED on the top is green (SAFE): alignment condition (in this case also the two intermediate yellow LED HIGH ALIGN, LOW ALIGN, are ON).

SB4-E/B/M/N Series Fig. 20 shows the two functioning modes.

Fig. 20 The selection of the manual/automatic Restart mode is made through the dipswitches placed under the slot of the receiving unit. In particular, the position 4 of both switches must be ON to activate the automatic Restart mode; OFF for the manual Restart mode.
Note: The dip-switches not used for this function are in grey. The lever position of the specific dip-switch is in black (ON) in the automatic Restart mode.

6.4. Reset function

The light curtain has a Reset function that is activated consequently to an internal failure. The operator has to press the TEST/START button resetting the break condition and thus return to normal functioning. The button has to be kept pressed for at least 5 seconds in one of the following conditions: Output failure; Optic failure; EDM test function failure; Teach-in Blanking failure.
Temporal diagram of the Reset function

6.5. EDM function

The External devices monitoring (EDM) function controls external devices by verifying the OSSD status. To correctly use this function: - select it using the specific dip-switch; - connect EDM input to the 24Vdc N.C. contact of the device to control.
The function controls the N.C. contact switching according to the changes of the OSSD status.
Tc 350 msec time after the OSSD OFF-ON passage when EDM is carried-out Tmsec time after the OSSD ON-OFF passage when EDM is carried-out
The use of non-conform devices may cause failures. The periodical testing of the function is recommended.
The correct dip-switch positioning (dip 3 OFF) for the function activation is shown here aside.

6.6. Blanking function

(only in some models, see section 10 List of available models)
The Blanking function deactivates a specific zone of the detection field in order to guarantee that the presence of an object in this area does not interrupt the functioning of the controlled machine. Two Blanking modes can be configured: Floating Blanking and Fixed Blanking. These modes can be activated singularly or contemporarily.

6.6.1. Floating Blanking Allows the Blanking of 1, 2 or 3 beams positioned in any zone of the detection area. Dip-switches 1 and 2 configure the number of beams to deactivate. Floating blanking OFF
Floating Blanking deactivated
Note: Floating Blanking can not be applied on the first top beam as it carries-out the synchronism functions. If an object interrupts the first beam during functioning, even if Floating Blanking is activated, the OSSD outputs open and the light curtain enters into the BREAK status.
Safety distance change The activation of the Floating Blanking function provokes a reduction of the device resolution. Consequently, the safety distance has to be recalculated according to the real device resolution (see table in section 2.2.1).
Blanking lamp The Floating Blanking activation is signalled by two LEDs positioned on the top of the receiving unit. The LEDs continue to blink for the entire duration of the Floating Blanking.
Display LED for Floating Blanking signalling Display LED
Green ON OFF Yellow ON Green ON
Status The light curtain is ON and the Floating Blanking function is activated.
Green ON Yellow blinking Yellow ON Green ON
The Floating Blanking function is activated and an object is interrupting beams in the controlled area.
Instruction manual 6.6.2. Floating Blanking - 1 beam

ON OFF

Floating Blanking activated, 1 beam deactivated. All objects interrupting more than 1 beam are detected.
SB4-E/B/M/N Series 6.6.3. Floating Blanking 2 beams

OFF ON

Floating Blanking activated, 2 beams deactivated. All objects interrupting a number of beams different from 2 are detected.
The interruption of a number of beams, different from two (i.e. more or less than two), provokes the activation of the OSSD outputs of the safety light curtain.
6.6.4. Floating Blanking upto 3 beams (reduced resolution)
Floating Blanking activated, 1, 2 or 3 adjacent beams deactivated. Blanking is activated up to the interruption of 3 beams. All objects interrupting more than 3 beams are detected.

OFF OFF

Differently from the other applications, this configuration accepts all objects that interrupt upto 3 beams and not only those exactly respecting the condition.
6.6.5. Fixed Blanking Allows the Blanking of a pre-set and fixed part of the controlled area. The position of the first beam involved and the dimensions of the area to deactivate have to be determined to guarantee the correct Blanking functioning. The data is acquired by a TEACH-IN procedure, explained herein: To activate the TEACH-IN acquisition, a 24 Vdc voltage has to be applied for at least 3 sec on pin 3 (green) of the receiver M12 8-pole connector. This function is usually controlled by a pushbutton. For now onwards, a pressed push-button condition refers to the application of the 24 Vdc voltage on the input and released push-button condition refers to a 0 Vdc voltage (TEACH-IN deactivated). The TEACH-IN activation is signalled as follows: Red ON OFF Yellow blinking Green ON During TEACH-IN, keep the push-button pressed in order to continue the sequence. In this phase the OSSD outputs are deactivated.

The acquisition of the necessary information is carried-out interrupting the beams on which the Blanking function has to be applied. Only one single Blanking area can be memorised and thus, during TEACH-IN, all the interrupted beams must be contiguous. If a beam is not deactivated inside the area to memorise, situation similar to the effort to memorise two different areas, the system enters in Blanking functioning failure status (see table).
The TEACH-IN is confirmed releasing the push-button. The OSSD outputs return active at the push-button releasing. Note: TEACH-IN can not be applied on the first top beam as it carries-out the synchronism functions. If at the pushbutton release, the first beam is deactivated, the system enters into Blanking functioning failure status (see table on next page).
A 1 minute Time-out period is foreseen in the TEACH-IN procedure. At the expiry the system enters into the Blanking functioning failure status (see table).

3 sec 24 Vdc Tout 1min

The TEACH-IN procedure can be repeated during normal device functioning. The information acquired during TEACH-IN is memorised also after device powering off. A reset function of the TEACH-IN carried-out is not available. To guarentee the same result, the TEACH-IN function has to be repeated enuring that all beams are free. An activation/deactivation function of the Fixed Blanking does not exist. A tempory deactivation can be obtained leaving the pin 3 (green) of the receivers M12 8-pole unconnected. ATTENTION: Fixed Blanking differently from Floating Blanking is not signalled by the safety light curtain. Consequently all the necessary precautions has to be taken before powering the device: Mount warning signs near the unprotected area to signal possible risks. Use protective stands and/or metal nets to avoid access, through the Blanking zone, into the machine dangerous area.
NOTE: A significant difference between the Fixed and Floating Blanking functions exists. Floating Blanking accepts that the number of beams forseen for Blanking is both interrupted as well as free (E.g.: the Blanking of 2 beams has been selected. During functioning two beams can be interrupted as well as none). In Fixed Blanking, the area memorised during TEACH-IN must always be obscured during functioning. Removing the object from the Blanking area, the light curtain enters in a Blanking functioning error status (see table on the bottom of the page). Blanking functioning error signal Display LED

7. DIAGNOSTIC FUNCTIONS

7.1. Visualisation of the functions
The operator can visualise the operating condition of the light curtains through four LEDs positioned on the receiver unit and two LEDs on the emitter unit (Fig.21).
Fig. 21 The reason for the LEDs positioned on the receiver unit (RX) depends on the functioning mode of the safety light curtain.
7.2. Fault and diagnostic messages

8. CHECKS AND PERIODICAL MAINTENANCE
The following is a list of recommended check and maintenance operations that should be periodically carried-out by qualified personnel. Check that: The ESPE stays locked during beam interruption along the entire protected area, using the suitable Test Piece. Pressing the TEST/START button, the OSSD outputs should open (the red BREAK LED is ON and the controlled machine stops). The response time at the machine STOP (including response time of the ESPE and of the machine) is within the limits defined by the calculation of the safety distance (see section 2 Installation Mode). The safety distance between the dangerous areas and the ESPE are in accordance with the instructions included in section 2 Installation Mode. Access to the dangerous area of the machine from any unprotected area is not possible. The ESPE and the external electrical connections are not damaged. The frequency of checks depends on the particular application and on the operating conditions of the safety light curtain.

8.1. Maintenance

The SB4-E/B/M/N safety devices do not require any particular maintenance, with the exception of the cleaning of the protection front surfaces of the optics. When cleaning, use a cotton cloth dampened with water. Do not under any circumstances use: - alcohol or solvents - wool or synthetic cloths
8.2. General information and useful data
The safety devices fulfil their safety function only if they are correctly installed, in accordance with the Standards in force. If you are not certain to have the expertise necessary to install the device in the correct way, CARLO GAVAZZI Technical Service is at your disposal to carry-out the installation. Auto-regenerating type fuses are used. Consequently, in presence of a short-circuit, these fuses protect the device. After the intervention of the fuses, it is necessary to disconnect the power supply and wait for 20 seconds so that the fuses can automatically restart normal functioning. A power failure caused by interferences may cause the temporary opening of the outputs, but the safe functioning of the light curtain will not be compromised.

8.3. Warranty

All appliances are under a 36 month warranty from the manufacturing date. CARLO GAVAZZI will not be liable for any damages to persons and things caused by the non-observance of the correct installation modes and device use. The warranty will not cover damages caused by incorrect installation, incorrect use and accidental causes such as bumps or falls. In presence of a non-functioning device, always return the emitting and receiving units for repair or replacement. In presence of failures send the both units to CARLO GAVAZZI Controls - Sensors Division Technical Service Tel.: +4178811 Fax.: +4178800 email: cust.service@gavazziacbu.it

* 0.5 m or 1 m shielded cables with 5-pole M12 connector for the Master and Slave connection must be ordered in combination with the SB4-E/B/M/N Cascade light curtains. ** The 5-pole M12 connector for the Master termination (M/U STD accessory) has to be connected instead of the Slave during the alignment phase of the Master unit. Once aligned and definitively mounted, the Master has to be disconnected from the M/U STD termination connector. The Slave has to be then connected and aligned. Moreover, the termination connector has to be definitively inserted if a Master couple is to be used singularly, that is without a Slave couple.
Note: a couple of M/U STD termination connectors are supplied with SB4-E/M/NS Cascade light curtains. Laser pointer The laser pointer of the LASP series represents a valid alignment and installation support for the SB safety light curtain series. The pointer can be moved along the light curtain profile to verify the complete device alignment (top and bottom).
