1. GENERAL INFORMATION
1.1. General description of the safety light curtains
The safety light curtains of the PSEN op2H-s 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 PSEN op2H-s series are Type 2 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: electro-
sensitive protective equipment. Part
1: General prescriptions and tests.
CEI IEC 61496-2: 2006 Safety of machinery: electro-
sensitive protective equipment -
Particular requirements for
equipment using active
optoelectronic protective devices.
The device, consisting of one emitter and one receiver housed inside
strong aluminium profiles, generates infrared beams that detect any
opaque object positioned within the light curtain 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 electrical
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 –through
some LEDs –informs the operator about the general conditions of
the safety light curtain (see section 7 “Diagnostic functions”).

PSEN op2H-s Series Instruction Manual

The device consists in 2 units that, according to the model, are
composed by one or several emitting and receiving modules.
The receiver checks the control operations and safety actions.
During installation, two yellow LEDs facilitate the alignment of both
units (see section 5 “Alignment procedure”).
As soon as an object, a limb or the operator’s body accidentally
interrupts one or some of the infrared beams sent by the emitter, the
receiver immediately opens the OSSD outputs and blocks the MPCE
machine (if correctly connected to the OSSD).
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 Pilz Technical Service for any
necessary information relative to the functioning of the PSEN op2H-s
light curtains and the safety rules that regulate the correct installation
(see section 8 “Periodical checks ”).

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, after having
evaluated the risk assessment:
1.3.1. 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 = 30 mm
hand protection
Type 2
As shown in Fig.1, the resolution only depends on the geometrical
characteristics of the lenses, diameter and distance between centres,
and is independent from 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 between two adjacent optics
d = Lens diameter

1.3.2. Controlled height
The controlled height is the height protected by the safety light
curtain ( Hp )
Fig. 2
The PSEN op2H-s controlled height is delimited by the yellow line
pad-printed on the front glass and by the dimensions listed in the
table:

1.3.3. 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 AOPD.
The safety distance depends on 4 factors, according to the EN-999
Standard:
•Response time of the AOPD (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 AOPD and the real stop of the dangerous
motion of the machine).
•AOPD 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/sec.
t1= Response time of the AOPD in seconds (see section 9
“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
device trips.
C = 8 (d -14) for devices with resolution 40mm
C = 850 mm for devices with resolution 40mm.
