7-1 Glossary
Machinery Directive
This directive applies to assemblies of linked parts or components
powered by electricity, compressed air, oil pressure, or other means,
consisting of at least one component which moves and a compo-
nent which fulfills a safety function, and which is sold in the market
as a single unit.
EMC Directive
This directives applies to electric or electronic devices which may
create electromagnetic interference, or whose performance may be
affected by electromagnetic interference.
EN 61496-1
IEC 61496-1/2
ANSI/UL 61496-1/2
JIS B 9704-1/2
Standards that pertain to machine safety, especially electrosensi-
tive protective equipment (ESPE).
EN 61496-1, IEC 61496-1, ANSI/UL 61496-1 and JIS B 9704-1 give
general rules for failure mode and effect analysis, EMC require-
ments, and other matters. IEC 61496-2, ANSI/UL 61496-2 and JIS
B 9704-2 specify effective aperture angles and protection against
extraneous light sources for Active Opto-electronic Protective De -
vices (AOPDs).
IEC 61508-1 to 7
JIS C 0508-1 to 7
Standards that pertain to general functional safety for electrical,
electronic, and programmable electronic devices.
These standards prescribe methods, safety integrity levels (SIL),
and other specifications that reduce risk to a tolerable level of prob -
ability.
EN 55011
Specifies the allowable levels and measurement methods for ra-
dio interference characteristics of industrial, scientific and medical
(ISM) radio-frequency equipment.
EN ISO 13849-1
EN 13849-1
JIS B 9705-1
Standards for safety-related matters of machine safety / control sys-
tems.
These standards specify levels (categories) of structure and fault
detection reliability, and levels of safety function performance capa-
bility (PL: Performance Level).
ESPE Abbreviation for Electro-Sensitive Protective Equipment.
Control output (OSSD)
Abbreviation for Output Signal Switching Device.
A component of the light curtain that turns OFF when light of the
light curtain is blocked.
FSD
Abbreviation for Final Switching Device.
This is a component of the machine’s control system that breaks the
MPCE circuit when the OSSD outputs an OFF signal due to the light
from the light curtain being blocked.
Test rod
Rod for checking the detection capability of the device.
The size of the rod is equivalent to the minimum sensing object.
Lockout
One of the safety states of the device. Operation stops when the
self-diagnosis function determines that an irrecoverable failure (OS -
SDs not operating normally, etc.) has occurred. When the emitter is
in the lockout state, the OSSD and SSD of the receiver turn OFF.
When the receiver is in the lockout state, the OSSD and SSD turn
OFF.
