Override Function - Panasonic SF4D Series Instruction Manual

3-8 Override Function (12-core cable)
● 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
Overriding 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.
The override function forcibly invalid the safety functions of the device. Use the override func-
tion when you want to start the machine when the control output (OSSD 1 / 2) is OFF while the
muting function is being used, or when the muting sensor is ON while the line is starting.
The override function is valid when the following conditions are all satisfied.
● A signal is input to one or both of muting inputs A and B.
● The override input is shorted to 0V or +V, and the test / reset input is open.
(Continuously for 3 seconds)
The override function is invalid if at least one of the two conditions is not satisfied, or if 60 sec.
elapses.
Note: The override function only operates when auto reset is selected (interlock invalid).
<Reference>
You can set an interval from 60 to 600 sec. in increments of 10 sec. using the communication
module SF4D-TM1 (option) and Configurator Light Curtain software.
