Glossary
Machinery Directive
This directive is for an assembly of linked parts or components, energized
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 re-
leased into the market by itself.
EMC Directive
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.
EN 61496-1
IEC 61496-1/2
UL61496-1/2
JIS B 9704-1/2
The standards that pertain to machine safety, especially electro-sensitive
protective equipment (ESPE).
EN 61496-1, IEC 61496-1, UL 61496-1 or JIS B 9704-1 gives general rules
or failure mode and effect analysis, EMC requirements, etc.
IEC 61496-2, UL 61496-2 or JIS B 9704-2 specifies effective aperture an-
gle, protection against extraneous light sources, etc, for Active
Opto-electronic Protective Devices (AOPDs).
EN 55011
Specifies the limits and methods of measurement of radio disturbance
characteristics of industrial, scientific and medical (ISM) radio-frequency
equipment.
JIS B 9705-1
(ISO-13849-1)
The standard that specifies the safety-related matters of machine safety /
control system.
UL1998
UL standard for safety-related software in programmable components.
Model Examination
The standard for safety equipments structure of the Japanese Ministry of
Health, labor and Welfare.
ESPE
The abbreviation for Electro-Sensitive Protective Equipment.
Output control
(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 di-
mensions corresponding to the minimum sensing object for this device.
Main side / Sub side For series connection, the side where the power supply or the output is
connected is called the main side, and the others are called the sub side.
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 condi-
tion, 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 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.
