Chapter 7 Others
7-1 Glossary
Machinery Directive
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.
EMC Directive
The directives is to any electric or electronic devices which will cre-
ate more than a limited amount of RF interference, or will withstand
a certain amount of Electro Magnetic fields while operating as in
-
tended within specifications.
EN 61496-1
IEC 61496-1/2
ANSI/UL 61496-1/2
JIS B 9704-1/2
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
general rules or failure mode and effect analysis, EMC require-
ments, etc. IEC 61496-2, ANSI/UL 61496-2 or JIS B 9704-2 speci
-
fies effective aperture angle, protection against extraneous light
sources, etc, for Active Opto-electronic Protective Devices (AOPDs).
IEC 61508-1 to 7
JIS C 0508-1 to 7
The standards that pertain to general functional safety for electri-
cal, electronic, and programmable electronic devices.
These standards prescribe the methods, safety integrity levels (SIL)
and other specifications that reduce the level of risk to a tolerable
level of probability.
EN 55011
Specifies the limits and methods of measurement of radio distur
-
bance characteristics of industrial, scientific and medical (ISM)
radio-frequency equipment.
EN ISO 13849-1
ISO 13849-1
JIS B 9705-1
The standard that specifies the safety-related matters of machine
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).
ESPE
The abbreviation for Electro-Sensitive Protective Equipment.
Control output (OSSD)
The abbreviation for Output Signal Switching Device.
A component of the light curtain that turns OFF when light of the
light curtain is blocked.
FSD
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.
Test rod
This is a rod for checking the detection capability of this device.
It has dimensions corresponding to the minimum sensing object for
this device.
Lockout
It is one of the safe status of this device. Operation is stopped if
the self-diagnosis function determines that an irrecoverable failure
(OSSDs 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.
Safety distance
It is the minimum distance that must be maintained between the
light curtain and the dangerous parts of a machine so that the ma-
chine can be stopped before a human body or an object can reach
the dangerous parts.
