General description of the safety devices

Safety light curtains from the PSEN op 2/4 series are optoelectronic
safety devices. They secure work areas in which operating personnel
can come into contact with moving parts of machinery, robots and
automated systems in general, which present a risk of physical injury.
Safety light curtains in the PSEN series are designed as safe Type 2
or Type 4 systems, for accident prevention in accordance with
applicable international standards, in particular:
EN 61496-1: 1997
Safety of machinery: Electrosensitive
protective equipment. Part 1: General
requirements and tests.
prEN 61496-2: 1997
Safety of machinery - Electrosensitive
protective equipment. Part 2: Particular
requirements for equipment using active
optoelectronic protective devices.
The device, which consists of a transmitter and a receiver housed in
robust aluminium profiles, secures the protected area by generating an
infrared protected field, defined by the height and width of that
protected field.
Both the control and evaluation logic
are located inside the two units; the
electrical connection is made via M12
connectors, which are positioned
underneath the profiles.
transmitter and receiver
synchronised optically, so the two
units do not have to be connected
directly to each other.
The infrared beams are controlled
and monitored via a microprocessor,
which also provides the user with
information about the operating status
of the light curtain via LED indicators
(see Chapter 7, "Diagnostic
functions").
