3-6 Muting Function (For SF4B-□CA-J05 only)
WARNING
● Incorrect using of the muting control may cause any accident. Please understand the muting
control fully, and use it. As for the muting control, the following international standards define the
requirements.
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
Overriding safeguards”
EN 415-4:
“Safety of packaging machines - Part 4: Palletizers and depalletizers, Annex A, A2.2 Muting”
ANSI B11.19-1990:
“for Machine Tools-Safeguarding When Referenced by the Other B11 Machine Tool Safety
Standards-Performance Criteria for the Design, Construction, Care, and Operation” 4.2.3 Pres

ANSI/RIA R15.06-1999:
“For Industrial Robots and Robot Systems - Safety Requirements, 10.4.5 Muting”
● Use the muting control while the machine cycle is not in danger mode. Maintain safety with the
other measure while the muting control is activated.
●
For the application that the muting control is activated when a workpiece passes through the
sensor, place the muting sensor so that the conditions for the muting control cannot be satisfied
by intrusion of personnel when the workpiece is passing through the sensor or the workpiece is
not passing through it.
●
Implement a risk assessment, and if a muting indicator is required, use it after checking the
standards and regulations in the country or region where the device is to be used.
● Be sure to check the operation of the muting function before its use.
This function turns the safety function into invalid temporarily. When the control output (OSSD
1 / 2) is ON, this function is available for passing the workpiece through the sensing area of the
device without stopping the device.
The muting function becomes valid when all the conditions listed below are satisfi ed:
● The control output (OSSD 1 / 2) shall be ON.
● Muting input A and B shall be changed from OFF (open) to ON. At this time, the time differ
-
ence occurred by changing the muting input A and B into ON status shall be 0.03 to 3 sec.
(Note 1)
The following devices, photoelectric sensor with semiconductor output, inductive proximity sen-
sor, position switch on NO (Normally Open) contacting point, etc. are available for applying to
the muting sensor.
Notes: 1) 0 to 3 sec. is allowable by using the handy controller Ver. 2.1 (
SFB-HC
) (optional) and connecting NO
(Normally Open) type muting sensor to the input A, as well as connecting NC (Normally Closed) type
muting sensor to the input B.
2) The muting indicator diagnosis function can be set with the handy controller Ver. 2 or later (
SFB-HC
)
(optional), but it must be set to invalid. If the muting indicator diagnosis function is set to valid, the mut
-
ing function cannot be used.
