Object Detection Capability (ODC)
The minimum size of object guaranteed to be detected when placed in the light curtain’s infrared
sensing field. A test piece of appropriate size is provided to test that the light curtain object
detection capability is within the parameter specified for the particular model number.
Transparent objects are not detected.
Range
This is the maximum scanning range of the light curtain between the Transmitter (TX) head and
Receiver (RX) head. Ensure the light curtain is capable of satisfying the range requirement for
the particular application it is being used for.
Reset Location
Reset devices must be located such that the danger area can be seen to be clear of persons
before the system is activated. The reset device should not be accessible from inside the
danger area.
Environmental factors can affect the operation of a safety light curtain and proper consideration
should be taken into account for mounting a system where fog, rain, smoke, dust, large
temperature fluctuations etc is a consideration.
Safety light curtains do not protect personnel from chemicals, heat, gases, radiation, flying parts
etc. They are not a physical barrier.
The machine operators must be instructed in the use of the safety light curtain by the
owner/provider of the machinery.

Figure E – Important Installation Considerations
1. Consider reflective surfaces that
may give rise to an optical ‘short
circuit’ from the direct path of the
safety light curtain’s infrared
beams as shown in the first
illustration of Fig. E. To ensure
the safety light curtain is mounted
far enough away from reflective
surfaces use the formula provided
to calculate the minimum distance
(X) between the light curtain and
reflective surface.
2. To prevent intermittent tripping of
the safety light curtain ensure that
extraneous infrared energy
between 800 and 1000
nanometers is not directed towards
the Perspex window of the receiver
unit (RX). Extraneous sources
would include infrared sensors,
infrared remote controls, scanning
systems or sunlight.
3. To prevent personnel from reaching
the danger point of the machine
additional mechanical guarding
may be required so that any access
has to be through the sensing field of the safety light curtain. The safety light curtain must be
positioned so as to prevent any overreach or under reach to the danger point. It must not be
possible to stand between the safety light curtain and the danger point.
The protection afforded by the safety light curtain should correspond to the machine Risk
Assessment under ISO 12100 for the machine being guarded.

4. Ensure the light curtain transmitter (TX) and receiver (RX) units are mounted accurately
in-line with each other and are both perpendicular and parallel to each other within the
parameters shown for each axis.
5. If utilising mirrors to deflect the light curtain ensure the mirror length is 50mm longer at either
end of the light curtain detection zone width and mounted centrally to the zone. To ensure
reliable operation the light curtain deflection angle (A) from the mirror must not be less than
40 degrees or greater than 100 degrees. (See Appendix 3)

Safety Light Curtain – T2A Series
Installation Guide
Warning Do not disconnect the cables from the Transmitter (TX) or Receiver
(RX) head with the power still connected to the T2A series light curtain.
Any wiring or re-wiring of the light curtain must be done with the power supply
disconnected.
Any input or output signals that are not being used must be terminated safe.
The machine must be disconnected during electrical installation to ensure no
inadvertent start up of the machine occurs.
The connection cables must be not be routed with high-voltage cables, e.g.
inverter cables or motor power supplies.
Power Supply
Use a regulated power supply +24V DC ±10% fused at 1.5A. The T2A light curtain current
consumption is rated at 0.5A + load current of the OSSDs. The Brown wire on both the
Transmitter (TX) and Receiver (RX) head cables must be connected to 24V DC (L+). The Blue
wire on both the Transmitter (TX) and Receiver (RX) head cables must be connected to 0V DC
(L-).
Before the power supply is applied to the light curtain ensure both TX and RX heads are aligned
correctly.
Warning The shield on both the Transmitter (TX) and Receiver (RX) head
cables must be connected to Earth (PE).
Only Automatic Reset mode
The automatic reset mode allows the safety light curtain to be reset automatically, that is, on a
blockage of the safety light curtain’s sensing field it will turn off the safety outputs (OSSDs).
Removing the blockage from the sensing field of the light curtain will re-activate and turn on the
safety outputs (OSSDs). The configuration of the safety light curtain in the auto reset mode will
depend on the customer’s risk assessment for the machine.

Safety Outputs OSSD1 and OSSD2
Two independent (PNP) electronic switching failsafe signal outputs (OSSDs) are provided for the
machine safety circuit. Interruption of the safety light curtains infrared sensing field will cause
the OSSDs to go to an OFF state and initiate a machine stop condition.
The connections are provided via the Black wire (OSSD1) and the White wire (OSSD2) on the
Receiver (RX) head cable.
Outputs ON = +24V DC (Light curtain clear)
Outputs OFF = 0V DC (Light curtain blocked)
The electronic outputs are monitored and rated at a maximum switching rating of 24V DC,
500mA. LED indicators located on the Receiver (RX) head show the status of the OSSDs.
Green LED ON = OSSD1 and OSSD2 active ON
Red LED ON = OSSD1 and OSSD2 inactive OFF

Figure J – Test and Maintenance
Testing the safety light curtain with the test piece
The test procedure should be carried out frequently as indicated by the risk assessment for the
particular installation.
A test must be carried out at the initial installation and prior to the machine start-up.
Smartscan Ltd recommends the test should be carried out daily.
Any changes to the configuration of the safety light curtain must be followed by testing to check
the system is still working correctly.
Regular function checking of the safety light curtain as well as at initial installation is required as
part of the test and maintenance process.
The operating instructions for the safety light curtain and machine must be made available for the
operator and those responsible for installation, maintenance and safety control at all times.
To test the safety light curtain power it up and activate the output switching circuits (OSSDs) to
an ON condition.
Insert a test piece of appropriate size into the light curtain detection zone, at the bottom, 150mm
from the transmitter unit. At this point the output switches will turn OFF. Sweep the test piece
up through the detection zone parallel to the transmitter.
Now sweep the test piece down through the detection zone equal distance between the
transmitter and receiver. Now sweep the test piece up through the detection zone 150mm and
parallel to the receiver unit. At no time during these tests should the output switches turn ON.
Now thrust the test piece anywhere in the light curtain detection zone and ensure the machinery
stops without apparent delay.
For light curtain models with an ODC above 40mm undertake the same tests as described.
During these tests the output switches should only turn OFF as the test piece totally obscures
each beam in the light curtain. Ensure that while the test piece is obscuring each beam the
output switches are OFF.

Maintenance
The Transmitter (TX) and Receiver (Rx) windows should be
cleaned regularly as indicated on the Installation Sheet, Figure K.
Dirt build-up or scratching on the windows may lead to intermittent
tripping or a totally blocked condition of the light curtain. Clear
adhesive tape may be applied to the windows of curtains in dirty or
abrasive conditions. Renew the clear adhesive tape periodically.
Dust particles can be attracted to the Perspex window due to static charges. This can be
prevented by the use of an antistatic plastic cleaner and antistatic
cloth.
Clean the windows with a clean damp cloth using a mild
detergent. Never use abrasive, corrosive cleaners or spray

Appendix 3 - Mirrors
Reflector mirrors can be provided enabling two or three sides of a machine to be safeguarded
with, what is effectively a single light curtain.
When mirrors are employed it is essential that the mounting of the transmitter unit, receiver unit
and mirrors themselves are sufficiently rigid. Alignment becomes increasingly critical as the
range and number of mirrors increase. Mirrors cause a reduction in optical efficiency, reducing
the effective range. A guide to the practicality of using mirrors is given below.
Range of the
light curtain
Maximum range

4m
Medium
Not Feasible
The angle of the infrared beams from the light curtain striking the reflective surface must be
within defined limits as per the drawings above.
Perimeter curtains will be easier to align, curtains over 900mm may be more difficult to align.
Check with the Smartscan technical department prior to ordering for a particular application,

Safety Light Curtain – T2A Series
Installation Guide
Alignment though one mirror
1. Secure the transmitter, receiver and
mirror units in the position in which they
are intended to be used.
2. Ensure all units are perfectly upright in
all planes by using a sprit level.
3. If the units are floor mounted on stands
ensure the floor is even. Shim the
floor mounts if necessary to ensure the units are all upright.
4. With one eye looking over the top of the receiver unit in line with the centre of the extrusion
look towards the reflective surface of the mirror, in a similar manner to looking through a gun
sight.
5. A second person must adjust the mirror to the left and right until the Perspex window of the
transmitter unit can be seen reflected in the mirror.
6. If the light curtain is scanning over a long range it may be difficult to see the reflection of the
transmitter units Perspex window in the mirror. If so, cut a piece of white paper to the size of
the Perspex window and mount directly in front of the window. Now repeat step 5.
7. If the reflection of the white paper is difficult to see in the mirror then employ a third person to
hold a flashlight in front of the transmitter unit with the light beam pointing directly in line with
the Perspex window towards the mirror. Now repeat step 5.
8. Use shims to ensure the mirror is accurately aligned to enable the infra red beams in the light
curtain to reach the receiver. Alternatively, fabricate mirror mountings to include some form
of adjustment to enable movement both left and right and also forward and backwards from
the central axis of the mirror.

Alignment though two mirrors
9.
Follow instruction 1-4
10. A second person must adjust the
position of the first mirror to the left
and to the right until the entire length
of the second mirror is reflected in the
first mirror. If difficulties are
experienced in seeing the reflection
on the second mirror in the first mirror
then use a piece of white paper cut to
size and position in front of the
second mirror.
11. If the reflection of the white paper is difficult to see in the first mirror then employ a third
person to hold a flashlight in front of the second mirror with the light beam pointing directly
in line with its mirror housing towards the first mirror. Secure the first mirror.
12. Again follow instructions 1 to 4.
13. The second person must adjust the position of the second mirror to the left and to the right
until the entire length of the transmitter unit is reflected through both the first mirror and the
second mirror. If difficulties are experienced in seeing the reflection of the transmitter unit
through both the first then the second mirrors then use a piece of white paper cut to size
and position in front of the transmitter unit.
14. If the reflection of the white paper is still difficult to see through the first and second mirrors
then employ a third person to hold a flashlight in front of the transmitter unit with the light
beam pointing directly towards the second mirror. Secure the second mirror.
15. Ensure the mirrors are directly aligned thus enabling the infra red beams of the transmitter
to reach the receiver. Alternatively, fabricate mirror mountings to include some form of
adjustment to enable movement both left and right and also forwards and backwards from
the central axis of each mirror.
16. Now turn on the power to the light curtain and check that the green LED beam indicator,
mounted on the receiver unit is ‘on’. If not, it may be necessary to finely adjust each mirror

in turn to ensure the infra-red energy from the transmitter unit is being reflected through the
mirror(s) to the corresponding receiver unit.
Alignment of the light curtain using mirrors
Note:
page 44
The mirror length must be a minimum of 100mm longer than the overall
length of the light curtain to be installed e.g. 50mm above and 50mm
below either end of the light curtain.
