4 Functions and features

Transmitter (T) Receiver (R)

P = protected area; I = protected area width (range); H = protected area height

The OY safety light curtains are multi-beam optoelectronic protective devices

according to IEC 61496 and consist of one transmitter and one receiver�

8

5 Function

The protected area (P) is generated between the transmitter and the receiver and

is defined by the protected area height (H) and the protected area width (range)

(I)�

The protected area height is the height protected by the safety light curtain�

It depends on the design (→ 12 Technical data).If the safety light curtains are

installed horizontally, this value indicates the depth of the protected area�

The protected area width (range) is the maximum distance between transmitter

and receiver (→ 12 Technical data).

If the protected area is clear, the two outputs (OSSDs) of the receiver are active�

If an object (O) with a diameter greater than or equal to the resolution (d) enters

the protected area, the outputs are switched off�

The resolution (d) (detection capability) of the safety light curtain depends on the

lens diameter (B) and the lens distance (C) and remains constant at all application

conditions�

6 Installation

6.1 Installation instructions

The following conditions are to be ensured before installation of the photoelectric

safety sensors:

• The degree of protection of the electro-sensitive equipment (ESPE) has to

correspond with the risk assessment of the machine to be monitored�

• The safety system ensures a safety function and is not required for the

operation of a machine�

• It must be possible to stop any hazardous motion of the machine immediately�

In this respect the shutdown delay of the machine has to be determined�

• The object to be detected must be greater than or equal to the resolution of the

photoelectric safety sensor�

Install the photoelectric safety sensors so that the hazardous area can only

be accessed via the protected area� Depending on the application other

mechanical protective equipment may be necessary�

The operating conditions at the mounting location must not affect the functioning

of the photoelectric safety sensors� Please note especially:

• The transmitter and the receiver must not be affected by intensive light sources

(emitters, sunlight etc�)�

• The ambient temperature must be within the range indicated (→ 12 Technical

data)�

• Fogging of the lenses due to considerable temperature fluctuations can affect

the functioning of the photoelectric safety sensors� Take appropriate measures

to prevent this�

• Certain operating conditions can affect the functioning of the photoelectric

safety sensors� For mounting locations where fog, rain, smoke or dust may

occur, it is recommended to take appropriate measures�

• The standards EN 999 and ISO 13855 must be adhered to�

10

Observe the following illustrations for correct installation of the photoelectric

safety sensors�

Wrong installation

6.2 Calculation of the minimum safety distance

There must be a minimum safety distance between the photoelectric safety sensor

and the point of danger� This distance must be ensured so that the point of danger

cannot be accessed before the hazardous state of the machine has been stopped�

11

UK





►Install the photoelectric safety sensor at a distance

that is greater than or equal to the minimum safety

distance (S) so that the hazardous area (A) can

only be accessed after complete standstill of the

hazardous machine motion�

According to the European Standard EN 999:2008, the

following formula is to be used to calculate the minimum

safety distance (S):

S = K (t1 + t2) + C

C = 8 (d - 14)

A = hazardous area

H = protected area height

S = min� safety distance

C = additional distance

S

6.3 Vertical installation of the safety light curtains

6.3.1 Safety light curtains resolution 14 mm

These designs are suitable for access prevention of fingers (finger

protection)�

The minimum safety distance (S) is determined using the

following formula:

S = 2000 (t1 + t2) + 8 (d - 14)

This formula applies to minimum safety distances (S)

between 100 and 500 mm� If the calculation shows that S

is greater than 500 mm, the distance can be reduced to a

minimum value of 500 mm by using the following formula:

S = 1600 (t1 + t2) + 8 (d - 14)









A = hazardous area

H= height

G = reference level

6.3.2 Safety light curtains resolutions 20 mm and 40 mm

These designs are suitable for access prevention of hands (hand

protection)�

The minimum safety distance (S) is determined using the

following formula:

S = 2000 (t1 + t2) + 8 (d - 14)

This formula applies to minimum safety distances (S)

between 100 and 500 mm� If the calculation shows that S

is greater than 500 mm, the distance can be reduced to a

minimum value of 500 mm by using the following formula:

S = 1600 (t1 + t2) + 8 (d - 14)









A = hazardous area

H= height

S = min� safety distance

G = reference level

If due to the special configuration of the machine it should be possible to reach

the hazardous area from above, the highest light beam of the safety light curtain

should be at a height (H) (measured from the reference level (G)) whose value is

determined to the specifications in ISO 13855�

13

UK

6.3.3 Safety light curtains resolution 90 mm

These versions are suitable for access prevention for bodies or

parts of bodies�

They must not be used for finger or hand protection!

The minimum safety distance (S) is determined using the

following formula:

S = 1600 (t1 + t2) + 850

The height (H1) of the upper light beam measured from the

reference level (G) must not be shorter than 900 mm while

the height (H2) of the lowest light beam must not exceed

300 mm (ISO 13855)�

6.4 Fixing and optical alignment

Correct alignment of the transmitter and the receiver is decisive for the

proper function of the photoelectric safety sensors�

►Install the transmitter and the receiver using the supplied mounting accessories

so that they are exactly opposite each other�

►Align the transmitter and the receiver so that they are in parallel at the same

height and the plugs face the same direction�

Adjustable brackets can be used to ensure easy optical alignment (available

as accessories)�

6.4.1 Optical alignment

T R T R T R T T

T = transmitter; R = receiver

The indication LEDs of the receiver help to correctly align the photoelectric safety

sensors�

►Align the transmitter so that the green LED of the receiver lights�

►Fix the transmitter and the receiver�

UK

6.5 Distance of reflecting surfaces

Reflective surfaces close to photoelectric safety sensors can disable the

safety function of the system�

The minimum distance (D) depends on the protective area width (I) taking into

consideration the projection and receiving angles�

The minimum distance (D) between reflective surfaces and the protected

area (P) must be observed� In case of non-compliance an object which

has to be detected cannot be sensed� In case of improper handling of the

product, the safety and physical integrity of persons and machinery cannot

be guaranteed�

6.7 Use of corner mirrors

To protect and monitor hazardous areas with access from several sides one or

several mirrors can be used (available as accessory)� By using mirrors the light

beam emitted by the transmitter can be sent via several access sides�

►To obtain a reflection angle of 90° the mirrors are to be oriented in an angle of

inclination of 45°�

The following image shows an application where U-shaped access protection is

implemented using two mirrors�

►Install the mirrors so that the minimum safety distance (S) is adhered to at each

side of the hazardous area�

►During installation make sure that the reflecting area is plane and that no

vibrations affect the safety device�

• The range is the sum of the length of all sides (D1 + D2 + D3) of the access to

the protected area� The maximum range of the photoelectric safety sensors is

reduced by 15% for each mirror�

• Do not use more than three mirrors�

8 Operating modes

The OY series safety light curtains with blanking function support automatic

operation only� In case of a clear protected area, the outputs (OSSDs) are

automatically re-enabled�

Please make sure if this is compatible with the risk assessment of your

machine�

Manual operation with start / restart button is only supported in connection

with the safety relays G1501S, G1502S and G1503S� For most

applications, this safety function is mandatory�

Outputs OSSD1 and OSSD2 follow the status of the safety light curtains:

Protected area clear Outputs = active logic "1"

Protected area interrupted Outputs = deactivated logic "0"

8.1 Floating blanking function

The safety light curtains have a floating blanking function that cancels the

monitoring of up to three neighbouring beams� This function is suitable for

applications where the protected area is interrupted by the material to be

processed or a part of the machine�

The synchronisation beam (first beam above the display) is excluded from

the blanking function�

When the blanking function is used, the resolution of the safety light curtains

decreases�

22

If the interrupting object is narrower than the protected area, the clear area

has to be protected by means of mechanical equipment� If the object moves

vertically, the protective equipment has to move accordingly�

unprotected clear area clear area protected by mechanical

equipment

The safety light curtains support two different types of blanking:

- Blanking without permanent object within the protected area�

- Blanking with a permanent object within the protected area�

23

UK

8.1.1 Blanking without permanent object within the protected area

With this setting, a moving object may interrupt the protected area without

deactivating the outputs of the safety light curtains� If the object is removed from

the protected area, the outputs remain active� This function reduces the resolution

of the safety light curtain (→ 8.1.1 Table Effective resolution A).

Blanking without a permanent object within the protected area permits three

different operating modes:

1. Blanking of up to one beam (A1):

If no or only one beam is interrupted, the protected area is considered as clear�

8.1.2 Blanking with a permanent object within the protected area

With this setting, an object within the protected area, e�g� a part of the machine,

can be permanently blanked�

As long as the light curtain is activated, the object has to be within the

protected area at all times�

The size of the object must not be below the nominal resolution of the safety

light curtain or the distance between the beams (in case of 90 mm designs)�

The resolution of the safety light curtain only decreases within and at the limits of

the blanked area� If the interrupting object covers the entire width of the protected

area, (→ 8.1.2 Table Effective resolution B) applies.

If the object is narrower than the protected area, the values mentioned in (→ 8.1.1

Table Effective resolution A) apply within and at the limits of the blanked area� (B1

is equivalent to A2 and B2 to A3�)

Blanking with a permanent object within the protected area permits two operating modes:

1. Blanking of up to two neighbouring beams (B1):

If no beam is interrupted, the outputs switch off since no permanent object is

detected ("b" is indicated on the receiver display)� If up to two neighbouring beams

are interrupted, the protected area is considered as clear�

operation�

8.3 Test function

For the test function, the photoelectric safety sensors can e�g� be tested by a

process control system or a control module ( → 7.1 Table Protected area width

configuration)�

The test pulse interrupts the light emission by the transmitter and the outputs carry

a 0 signal (→ 10.1 Switching states of the outputs).

The minimum duration of the test command is 40 ms�

8.3.1 Internal test function

Type 4 safety light curtains continuously perform internal tests� The faults are

detected within the response time of the respective model leading to switch-off

(response times → 12 Technical data).

10.1.1 The safe state

The safe state is when the output is switched off (zero-current state: logic "0")

of at least one of the outputs (OSSDs)�If one of the outputs is switched off, the

subsequent safety-related logic unit must bring the complete system into the state

defined as safe�

10.1.2 The switched state

In switched state, the receiver provides a current of 24 V DC (logic "1") to both

outputs�

14 Maintenance, repair and disposal

• Maintain the optoelectronic protective equipment in accordance with the

applicable national regulations within the requested intervals� The tests must

be performed by qualified persons�

• It is recommended to regularly clean the front panes of the transmitter and the

receiver�

• Clean the unit with a clean, damp cloth� In particularly dusty environments we

recommend to spray the cleaned front pane with an antistatic product�

• Do not use any aggressive or abrasion-developing cleaning agents since they

could attack the surfaces� To avoid electrostatic charging on the front, do not

use any woollen cloths�

Scratches on the front panes of the photoelectric safety sensors may

deviate the light beams and impair the protective function�

• Only the manufacturer is allowed to repair the unit�

• After use dispose of the unit in an environmentally friendly way in accordance

with the applicable national regulations�
