5-3 Muting function (12-core cable)
WARNING
● Risk of an accident if muting control is used incorrectly. Fully understand the muting function be -
fore use. Requirements for muting control are given by the international standards below.
ISO 13849-1 (EN ISO 13849-1, JIS B 9705-1):
“Safety of machinery - Safety-related parts of control systems - Part 1: General principles for de-
sign, Article 5.2.5 Muting”
IEC 61496-1 (ANSI/UL 61496, JIS B 9704-1):
“Safety of machinery - Electro sensitive protective equipment - Part 1: General requirements
and tests, Annex A, A.7 Muting”
IEC 60204-1 (JIS B 9960-1):
“Safety of machinery - Electrical equipment of machines - Part 1: General requirements, 9.2.4
Suspension safeguards”
EN 415-4:
“Safety of packaging machines - Part 4: Palletizers and depalletizers, Annex A, A2.2 Muting”
ANSI/RIA R15.06-2012:
“U.S.A. Standards for Industrial Robots and Robot Systems - Safety Requirements, 5.10.10
Muting”
● Use muting control when the machine cycle is not dangerous. Maintain safety by other methods
while muting control is activated.
● In an application where muting control is activated when a workpiece passes through, place the
muting sensor so that the conditions for muting control are not satisfied when a person intrudes,
regardless of whether or not a workpiece is passing through.
● Conduct a risk assessment, and if a muting indicator is required, check the standards and regula-
tions in the country or region where the device is to be used and install the indicator accordingly.
● Be sure to test operation before using the muting function.
● Always operate the device that starts the override function manually. Install the device for over-
ride function startup in a location that allows operation from outside the danger zone and which
provides a clear view of the entire danger zone.
● Always verify that no one is in the danger zone before using the override function. Risk of death
or serious injury.
5-3-1 Muting input A / B wire and override function
The input / output specification and synchronization method determine incorporated / not incor -
porated of muting input A wire (pink) / B wire (yellow) and override function valid / invalid of the
light curtain.
If light curtain muting input A wire (pink) / B wire (yellow) is set to "Incorporated", muting by mut -
ing input A wire (pink) / B wire (yellow) is possible.
When the override function is set to "Valid", the override function can be used.
