1 System Overview and Applications
Summary - Focus II light curtain/grid, Type 4 (FII-4-)

6
2TLC172015M0201, rev. D www.abb.com/lowvoltage
1.1 General Data
Focus II light grids and curtains are active optoelectronic protective devices, AOPD, of type 4 by
EN 61496-1 and IEC 61496-2. They are intended to be used where it is essential to safeguard operators
of hazardous machinery, robots, or other automated systems where access to hazardous parts may be
gained.
Before using the Focus II units, all personnel responsible for installation and maintenance of this equipment
must ensure that they have read and understood the information contained in this manual. It is essential
that units are installed and used according to the instructions in this manual. All relevant standards and
regulations regarding the use of this type of equipment must also be strictly adhered to.
1.2 Maintenance
With the exception of checking alignment and cleaning the polycarbonate front covers that protects the
optics, no part of the safety barrier needs to be maintained or can be repaired by the user. The installation,
however, should regularly be checked and the results recorded. Should there be any errors, the barriers
must be sent to our service location together with an error description as well as estimated operating time.
NB! Damage or dirt on the cover does not compromise the safety level of the barriers but may cause
operational disturbance. Do not use woollen cloth, solvent or any other material when cleaning, which may
scratch or in some way damage the surface of the cover. Operational conditions decide how often the cover
needs to be cleaned.
ABB AB JOKAB SAFETY does not accept any liability for damage or injury due to incorrect use of the
protection barriers or associated components.
1.3 Important information
The Focus II system must be installed, congured, and incorporated into a machine control system by a
sufciently trained and qualied person. An unqualied person may not be able to perform these operations
properly, which may cause a person to go undetected in to the hazardous area, resulting in serious injury.
When changes are made to each function using the selector switches, the administrator must manage the
detail of the changes and perform the changes. Accidental functional setting change may cause failure of
human body detection, resulting in a serious injury.
Do not drop the products. Dropping the products may lead to internal or external damage. Please return a
Focus II system that was dropped on the oor to your ABB AB JOKAB SAFETY service for inspection or
repair. Failure to do so may result in serious injury.
Make sure to test the operation of the Focus II system after installation to verify that the Focus II system
operates as intended. Make sure to stop the machine until the test is complete. Unintended function
settings may cause a person to go undetected, resulting in serious injury.

7
www.abb.com/lowvoltage 2TLC172015M0201, rev. D
Install the reset button in a location that provides a clear view of the entire hazardous area and where it
cannot be activated from within the hazardous area.
The Focus II system cannot protect a person from a projectile exiting the hazardous area. Install protective
cover(s) or fence(s).
A sufciently trained and qualied person must properly congure muting related timings for its specic
application, and that person must have responsibility for settings, especially when the muting time limit is
innite.
Install the switch that activates the override in a location that provides a clear view of the entire hazardous
area and where it cannot be activated from within the hazardous area. Make sure that nobody is in the
hazardous area before activating the override function.
Do not place uorescent and/or incandescent lights within the effective aperture angle of the receiver, as it
may inuence the Focus II system under certain circumstances. Install the sensor system so that it is not
affected by any ref lective surfaces. Failure to do so may hinder detection, resulting in serious injury.
When using more than 1 set of Focus II system, install them so that mutual interference does not occur,
such as by conguring series connections or using physical barriers between adjacent sets.
2 Function and Possibilities (Short Description)
A beam of infra-red light is generated and sent from transmitter to receiver. If anyone should interrupt this
beam, the OSSD outputs of the safety barriers (see 5.1) are opened, and brings hazardous functions in
machinery to a safe state.
Safety barriers come in heights between 150 mm and 2400 mm and the reaction time is between 13 ms
and 103 ms, depending on the model.
Electric connection is made via an M12 connector. Steering and control of beams that are transmitted and
received is made by two microprocessors, which also transmit all information on status and alignment of the
barrier via f our LEDs in the transmitter and f ive in the receiver (see 14, 15).
Focus II contains many good and user-friendly functions. Below is a summary with references to the
respective chapters that contain more information.
Muting (see 6) means that one or more segments, or the whole barrier, may be bypassed when material is
passed through it. If a light grid is used, one or more beams, or the whole grid, may be bypassed.
Override (see 7) is a function which makes it possible to bypass the light barrier and activate the OSSD
outputs if machine start is necessary, when one or more beams are interrupted.
NB! Muting and override demands a connected muting indicator (LMS) (or resistor 220 Ω, 3 W) before
power is switched on.

8
2TLC172015M0201, rev. D www.abb.com/lowvoltage
Floating blanking (see 9) makes it possible for a number of beams to be constantly interrupted in the
protection area. With oating blanking, the object can move in the protection area without triggering the
safety function. Other beams are active with normal safety function but with reduced resolution.
Test/reset (see 5): This pushbutton is connected to +24 VDC during normal operation. It has several
functions:
A Test: A physical interruption of the protection area can be simulated by keeping the button pressed
down for at least 2.5 s.
B Reset: (see 4.6) If a connected button is pressed and released (manual reset) when the protection
area is clear again after having been disturbed, the light curtain is reset.
C Alignment: (see 3.2) If the button is pressed when voltage is connected, the barrier enters alignment
mode, i.e., when the alignment of the upper and lower beam is correct, LED 1, 2, 3 and 5 are lit to
indicate this.
D Override: (see 7) (Only and always possible when a muting indicator (LMS) is connected.)
If the button is pressed after 2 s but within 5 s after voltage has been switched on, and is then pressed
for at least 5 s, the OSSD outputs of the light curtain will be activated only if any beam is interrupted. If
the entire protective eld is free for more than 2 s this function is stopped.
Reset of Focus II light barrier can be reached in three different ways:
A Automatic reset: (see 4.6) The light curtain is reset immediately when the protection area is clear (=
not interrupted). Default setting by delivery.
B Manual reset: (see 4.6) The light curtain is reset immediately after the protection area is clear and the
reset button is pressed and released.
C Pre-reset: (see 8) The light curtain is reset when, f irst, the pre-reset button within hazardous area
is pressed, and thereafter, if the protection area is clear, when within 8 s the reset button outside the
protection area is pressed.
Safety outputs (see 5.2) OSSD 1 and 2 are opened when the protection area is interrupted.

Code not necessary
Code BCode A
3 Mechanical Installation
The location where the safety barrier is to be installed must full the technical requirements. Prior to
installation, the ambient temperature, electromagnetic and/or optical interference, among other things,
should be taken into consideration.
3.1 Mechanical Assembly
The prof ile of the light curtain is assembled with the accompanying brackets, and mounting screws that
slide in the prof ile slots (see 17-19, 22). These make it easier to adjust the transmitter and receiver in level
with each other.
NB! If several barriers are used, they must be mounted so that each transmitter does not interfere with the
receiver of a nearby barrier. Multiple barriers should be installed as below or could be used with coding, see
4.5 and 5.6.
The scan code feature of the Focus II system allows for placement of systems in close proximity and in line
with each other. The distinctive coding of the beams provide for unique operation of a system while in view
of another system with a different scan code. Two unique codes are available on the Focus II, see section
4.3 on how to set the codes.

2TLC172015M0201, rev. D www.abb.com/lowvoltage
3.2 Alignment Procedure
When the safety barrier has been mounted, optical alignment of transmitter and receiver is made as
follows:
• Disconnect the barrier’s power supply. Open the test/reset (see 5.1).
• Restore the barrier’s power supply. The test/reset can then be closed again.
• Make sure that both units are in level, vertical and directed towards each other. Adjust by turning the
transmitter, left and right, until LED 2 and 5 of the receiver are lit. Turn the transmitter both ways to f ind
the outermost positions, return the transmitter to the midpoint. The barrier is correctly aligned when the
LED 3 is constantly lit even if one of the prof iles is somewhat turned.
• After aligning the barrier, secure the screws f irmly.
• Disconnect the power supply.
• Restore the barrier’s power supply (with the test/reset contact closed). If the safety area is clear and
automatic reset is chosen, the barrier will immediately enter operating mode, i.e. the OSSD outputs
are activated and the LED 1 and 3 are lit. If manual reset is chosen, test/reset must be pressed and
released before the OSSD outputs are activated.
• Complete the checks described in section 13 “Final Checks” and 16 “Routine Checks and Mainte-
nance”.

3.3 Calculation of Minimum Distance for Installation
The distance S is the minimum distance between light curtain/grid and hazardous area which prevents that
anyone comes in contact with hazardous machinery in operation before it stops. For calculation of S for a
curtain with multiple beams, the following is valid according to EN ISO 13855:2010:
Vertically assembled light curtain/grid
The minimum distance S for a vertically assembled light curtain/grid is determined in three steps:
a) Calculate minimum distance for reaching through the detection zone, SRT.
b) Calculate minimum distance for reaching over the detection zone, SRO.
c) Compare SRT and SRO. The minimum distance S is the greater of the two.
NB! If access to the hazardous area by reaching over the light curtain/grid can be excluded, e.g. by the
provision of guards or other protective measures, step b) and c) are not necessary.
a) SRT = (K × T) + CRT
K = approach speed of body parts towards hazardous area:
= 2000 mm/s shall be used if S is equal to or less than 500 mm. Min. value of S = 100 mm.
NB! If FII-4-30 is used in single/double break mode min. value of S > 150 mm.
= 1600 mm/s can be used if S is greater than 500 mm. Min. value of S = 500 mm.
T = Overall system stopping performance1= T1 + T2, where:
T1 = reaction time of light curtain/grid (s)
T2 = stopping time of machine, including reaction time of control system (s)
CRT = 8 × (d-14) mm for FII-4-14 and FII-4-30 (light curtains)
NB! If oating blanking is used and resolution ≥ 40 mm then CRT = 850 mm.
= 850 mm for FII-4-K versions (light grids)
d = resolution (mm) = 14 mm for FII-4-14 and 30 mm for FII-4-30.
NB! If oating blanking is used, see resolution table in chapter 9.

When a value of zero is given, the calculation of the minimum distance, S, should be made in accordance with chapter
3.3 Calculation of Minimum Distance for Installation, calculation point a).
NB! Electrosensitive protective equipment with a height of the:
– upper edge of the detection zone below 900 mm is not included since they do not offer sufcient protection against
circumventing or stepping over
– lower edge of the detection zone above 300 mm in relation to the reference plane does not offer sufcient protec-
tion against crawling below.
a Approach to the hazard zone by reaching over is impossible
NB! Values shall not be interpolated. Use nearest safer value.

c) Compare SRT and SRO. The minimum distance S is the greater of the two.
The following table is valid only for vertically assembled light grid with 2, 3, or 4 beams
(shall never be assembled horizontally):
Horizontally assembled light curtain
The minimum distance S from hazardous machinery to the farthermost beam is calculated using the same
formula as above but with different parameters, as follows:
S = (K × T) + C
K = 1600 mm/s. Approach speed of body parts towards hazardous area.
T= Overall system stopping performance = T1 + T2, where:
T1 = reaction time of light curtain (s)
T2 = stopping time of machine, including reaction time of control system (s)
C= 1200 - 0.4 × H. Shall not be less than 850 (mm)
H = 15 × (d-50). Minimum allowed height of detection zone above reference plane (mm)
NB! Shall not be less than 0 or greater than 1000.

4 Electrical Installation
4.1 Important Notes on Installation
NB! The two OSSD outputs shall be connected to the stop function of the machine, so that they each stop
the hazardous moving parts. The Focus II system is by default in auto reset mode.
– Power to the system shall be by a 24 VDC±20%, supply which complies with standard EN 60742 (dual
isolation), or with equivalent isolation by VDE 0551. We strongly recommend a stabilized power supply.
– Voltage shall be disconnected when changing the installation.
– The screen of the cabling to the barrier shall be connected to ground circuit.
– The barrier should be protected by a fuse with the value 1 A normal in the feeding voltage.
– The external muting indicator (LMS) signalling that the muting function is active, shall be connected and
work for the muting function to work. The indicator should be placed so that it is visible from all sides
with access to the hazardous area of the machine. See connection example in 5 and text in 6.
– The OSSD outputs of the barrier are PNP outputs which are each current limited to 500 mA. If the cur-
rent will exceed 500 mA or if alternating current is to be connected, the system may benet from being
connected to a safety relay, see 5.
– Do not install the Focus II system in the following types of environments:
Areas
• exposed to intense interference light, such as direct sunligh
• near the frequency controlled motors or wires to them
• near magnetic valves with coils without suppressors
• with high humidity where condensation is likely to occur
• where corrosive gases are present
• exposed to vibration or shock levels higher than in the specication
• where the product may come into contact with water
• where the product may come into contact with oil that is an adhesive solvent
– Do not use radio equipment such as cellular phones, walkie-talkies, or transceivers near the Focus II
system.

4.3 Setting up of Internal Change-Over Switches Transmitter
• Disconnect the power supply to the unit and open the small lid in the bottom cap (with the M12 con-
nector) so that the two change-over switches become visible.
• The change-over switches may be adjusted to the desirable position with a small, suitable screwdri-
ver.
NB! Make sure to always set switches in both banks to the same position.

1. Selector switches 4 and 5 are operational if a muting indicator is connected or both are set to the ON position.
2. The maximum time that Focus II will allow muting A or muting B to drop without detecting a muting stop. See 6.5.
3. Selector switches 1, 2 and 3 are operational if a muting function is set and a muting indicator is connected.
4. Selector switches 1, 2 and 3 are operational if selector switches 4 and 5 are in ON position.
5. Use this function if two NO muting sensors are used for X-muting (instead of one NO and one NC). Note that a new timing requirement is intro-
duced; muting A and muting B cannot be activated at the same time. A time difference of approx. 30 ms is mandatory.
6. Refers to max muting time (600 s) but not to the time between A and B (120 s).
NB! For further information about T-, L- and X-muting, see 6.1-6.5.

4.5 Setting up Scan Codes
The Focus II transmitter and receiver has the possibility of coding selection, to minimize interference when
two transmitters can reach one receiver.
NB! Both transmitter and receiver shall be set to the same code. All LEDs on transmitter / receiver ash
twice when code B is set correct, when powering up. Code A will ash once. Please make sure that the total
length of the cable between the transmitter and receiver (required when coding is used, see 5.6) does not
exceed 100 m.
4.6 Choice of Reset Procedure
Reset of Focus II barrier may be reached in three different ways:
A Automatic reset: The barrier is reset directly after the protection area has become clear. Change-over
switch No. 8 is set in position “On” (see 4.4).
B Manual reset: The barrier is reset when the protection area is clear and the reset button has been
pressed and released. Change-over switch No. 8 is set in position “Off” (see 4.4).
C Pre-reset: The barrier is reset when, f irst, the pre-reset button, which is normally placed inside
hazardous area, has been pressed (the yellow LED 5 in receiver is blinking) and, thereafter, if the
protection area is clear, within 8 seconds the reset button outside the area has been pressed and
released. (See 4.4 and 8)
