6-1 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
released 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
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 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)

EN 55011

Specifies the limits and methods of measurement of radio disturbance
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).

UL 1998

UL standard for safety-related software in programmable components.

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.

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
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 machine can be
stopped before a human body or an object can reach the dangerous parts.

Protective height
(Sensing height)

The length of the beam axis direction that the min. sensing object can be
detected.
The length from the center of the first beam channel to the center of the
last beam channel in addition to +50mm (+25mm upward, +25mm
downward).

Sensing range

It is the range between the facing emitter and receiver.

Sensing area

It is the area over which intrusion by people or objects can be detected by
one set of sensor. It is given by the product of the protective height and the
operating range.
