This directive is for an assembly of linked parts or components, en-
ergized by an electricity, compressed air or oil pressure, etc. and at
least one of which moves, and a component which fulfills a safety
function and is released into the market by itself.
The directives is to any electric or electronic devices which will create more
than a limited amount of RF interference, or will withstand a certain amount
of Electro Magnetic fields while operating as intended within specifications.
The standards that pertain to machine safety, especially electro-
sensitive protective equipment (ESPE).
EN 61496-1, IEC 61496-1, ANSI/UL 61496-1 or JIS B 9704-1 gives gen-
eral rules or failure mode and effect analysis, EMC requirements, etc.
IEC 61496-2, ANSI/UL 61496-2 or JIS B 9704-2 specifies effective
aperture angle, protection against extraneous light sources, etc, for
Active Opto-electronic Protective Devices (AOPDs).
Specifies the limits and methods of measurement of radio distur-
bance characteristics of industrial, scientific and medical (ISM)
radio-frequency equipment.
The standard that specifies the safety-related matters of ma-
chine safety / control system. They give roles for level (category)
of structure and fault detection reliability, and for level of safety
future performance capability (PL: Performance Level).
UL standard for safety-related software in programmable components.
The abbreviation for Electro-Sensitive Protective Equipment.
The abbreviation for Output Signal Switching Device.
A component of the light curtain that turns OFF when light of the light
curtain is blocked.
The abbreviation for Final Switching Device.
The component of the machine's safety related control system that
open-circuits the MPCE circuit when the OSSD operates due to the
light from the light curtain being blocked.
This is a rod for checking the detection capability of this device. It has di-
mensions corresponding to the minimum sensing object for this device.
For series connection, the sensor to which the power supply or the output
is connected is called main sensor, and the others are called sub sensor.
For parallel connection, the side where the emission / reception process tim-
ings are controlled is called master side, and the others are called slave side.
It is one of the safe status of this device. Operation is stopped if the
self-diagnosis function determines that an irrecoverable failure (OS-
SDs do not operate normally, etc.) has occurred. If an emitter is in
lockout condition, it will stop emitting light. If a receiver is in lockout
condition, OSSDs are turned OFF.
It is the minimum distance that must be maintained between the light cur-
tain and the dangerous parts of a machine so that the machine can be
stopped before a human body or an object can reach the dangerous parts.
The length of the beam axis direction that the min. sensing object
can be detected. The length from the center of the first beam chan-
nel to the center of the last beam channel.
