1. GENERAL INFORMATION
1.1. General Description of the safety light curtains
The safety light curtains of the OY32 series are optoelectronic multibeam devices that are
used to protect working areas that, in presence of machines, robots, and automatic systems
in general, can become dangerous for operators that can get in touch, even accidentally,
with moving parts.
The light curtains of the OY32 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:
CEI IEC 61496-1: 2004 Safety of machinery:
electrosensitive protective equipment. Part 1: General prescrip-
tions and tests.
CEI IEC 61496-2: 2006 Safety of machinery: electrosensitive protective equipment -
Particular requirements for equipment using active optoelec-
tronic protective devices.
The device, consisting of one emitter and one receiver housed inside strong aluminium pro-
files, generates infrared beams that detect any opaque object positioned within the light cur-
tain detection field.
The emitter and the receiver 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 elec-
trical connection between the two units is required.
The microprocessor guarantees the check and the management of the beams that are sent
and received through the units: The microprocessor LEDs inform the operator about the
general conditions of the safety light curtain (see section 7 “Diagnostic functions”).
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 operator’s body accidentally interrupts the beams sent by
the emitter, the receiver immediately opens the OSSD output and blocks the machine (if cor-
rectly connected to the OSSD).
Note: The following abbreviations, defined by the Standards in force, will be used in
this manual:

1.2. How to choose the device
There are at least three different main characteristics that should be considered when
choosing a safety light curtain, after having evaluated the risk assessment:
1.2.1. Resolution
The resolution of the device is the minimum dimension that an opaque object must have in
order to obscure at least one of the beams that constitute the sensitive area.
The resolution strictly depends on the part of the body to be protected.
R = 14 mm
Finger protection
Type 4
R = 30 mm
Hand protection
Type 4
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
where:
I = Distance betweentwo adjacent optics
d = Lense Diameter

1.2.3. Minimum Installation Distance
The safety device must be positioned at a specific safety distance (Fig. 3). This distance
must ensure that the dangerous area cannot be reached before the dangerous motion of
the machine has been stopped by the ESPE.
The safety distance depends on 4 factors, according to the EN-999 Standard:
Response time of the ESPE (the time between the effective beam interruption and the
opening of the OSSD contacts).
Machine stopping time (the time between the effective opening of the contacts of the
ESPE and the real stop of the dangerous motion of the machine).
ESPE resolution.
Approaching speed of the object to be detected.
Fig. 3
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/s
t1= Response time of the ESPE in secondes (see section 10 „Technical Data“).
t2= Machine stopping time in seconds
d = Resolution of the system
C = Additional distance based on the possibility to insert the body or one of body parts inside the
dangerous area before the protective devise trips.
C = 8 (d -14) for devices with resolution 40 mm
NOTE: K value 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
When devices with > 40 mm resolution are used, the height of the top beam has to be ≥ 900
mm (H2) from machine supporting base while the height of the bottom beam has to be ≤ 300
mm (H1).

If the safety light curtain must be mounted in a horizontal position (Fig.4), the distance be-
tween the dangerous area and the most distant optical 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 secondes (see section 10 „Technical Data“).
t2= Machine stopping time in seconds
H = Beam height from ground. This height must always be less than 1,000 mm.
Fig. 4
Practical Examples
Let's suppose to have a light curtain with height = 600 mm.
To calculate the distance of the device from the ESPE, in a vertical position, the following
formula is used:
S = K*T + C
where:
T = t1+ t2
t1= ESPE response time + safety relay release time (max 80 ms)
t2= Machine total stopping time
d = Resolution
C = 8 * (d –14) for devices with resolution <= 40 mm
In all cases, if K = 2000mm/sec then S > 500 mm. Distance will have then to be recalculat-
ed using K = 1600 mm/sec.

1.3. Typical applications
The safety light curtains of the OY32-series provide soulutions in all atomation fields where
the access to dangerous areas has to be controlled.
In particular, the safety curtains can be used in stopping moving parts in:
- Automatic machines;
- Packaging and cutting machines;
- Textile, wood-working and ceramic machines;
- Automatic assembling lines;
- Milling, lathe and shearing machines;
- Bending and metal-working machines.
Example 1: Operating point protection on drilling machines
The operator positions the part and takes it back after machin-
ing.
The operator must be protected against possible abrasions
while working
Solution: OY32013x safety light curtain is especially suitable for
this kind of application, which requires the installation of the de-
vice directly on the machine.
Benefits: The extremely reduced profile guarantees installation
flexibility adapting itself to the machine dimensions.
The rotating fixing brackets supplied as accessories, speed up
and facilitate mounting.
Example 2: Bending presses
The safety device must protect the operator from being squashed be-
tween the top and botttom parts or the machined part during the fast ap-
proach phase.
Solution: If only one beam of the OY32013x safety light curtain is in-
terupted while the press is moving down, the mobile tool bar will Stopp.
Benefits: The safety light curtain can be used in most bending operations
thanks to ist easy installation and compact dimensions. As well as offer-
ing excellent reliability, OY32013x ensures increased plant productivity as
it reduces the dead times necessary for machine accessing adjustment
and maintenance.

Example 3: Paper cutting machines
These machines typically cut paper to a specific size for newspa-
pers or spezial applications. The operator must be protected
against abrasion or cuts by cutter blades.
Solution: OY32010x safety light curtain is especially suitable for
this kind of application, which requires the installation of the de-
vice directly on the machine.
Benefits: Highly reduced profile and the two side slots ensure in-
stallation flexibility for machine dimensions.
The extremely reduced profile guarantees installation flexibility
adapting itself to the machine dimensions. The rotating fixing
brackets, supplied as accessories, speed up and facilitate mounting.
Example 4: Milling machines
