This is the optimal muting control for printing machines. 1 Put in an unfilled palette (Bottom-most muting) 2 Sample inspect the printing paper (Top-most muting) 3 Take out the printed material (All muting) Muting Normal operation Normal operation Muting Muting Normal operation Muting Normal operation Muting Muting pattern No.2 Muting pattern No.3 Set apart only the top-most sensor heads and perform muting control. Divide the muting area into two. (Ex.) Passing through of an object is allowed but passing through of a human will stop the machine. (Ex.) Allocate sensor heads at the entrance and exit of objects separately, so that muting is done individually. Normal operation Muting Normal operation Muting High-functional type ST4-C12EX Line restarts smoothly after being stopped while muting control was active In case the sensor head has been interrupted by an object or in case there is an emergency stop before the muting conditions have been established, all the sensor heads will be temporarily deactivated following by a smooth restart. (Ex.) When the power turns off while the sensor head has been interrupted by an object. Previous models Removal of object required Informs all kinds of operation conditions In case the muting lamp that is connected to the controller breaks, an alarm will go off. Also, auxiliary outputs that link to the muting function, override function, and control outputs (OSSD) are incorporated.

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 954-1 / JIS B 9705-1) IEC 61496-1 (UL 61496 / JIS B 9704-1) IEC 60204-1 (JIS B 9960-1) EN 415-4 ANSI B11.19-1990 ANSI/RIA R15.06-1999 • 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 an object 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 object is passing through the sensor or the object is not passing through it. • The muting lamp should be installed in a position where it can always be seen by operators who set or adjust the machine. • Be sure to check the operation of the muting function before its use. Furthermore, check the condition of the muting lamp (cleanliness or brightness, etc.). • This function turns the safety function of ST4-C12EX into invalid temporarily. • When the control outputs (OSSD1, OSSD2) are ON, this function is available for passing the object through the sensing area of the device without stopping the device. • The muting function becomes valid when all the conditions listed below are satisfied: • The control outputs (OSSD1, OSSD2) shall be ON. • The incandescent lamp with 1 to 10 W shall be connected to the muting lamp output. • The muting inputs between S-A and S-B (between S-C and S-D, or between S-E and S-F) shall be changed from OFF (open) to ON. The time difference from OFF to ON shall be 0 to 3 sec. • However, if exceeding 180 sec. time limit, the muting function will be invalid. In addition, the muting valid time can also be changed to unlimited. For details on the setting method, refer to the “Muting pattern selection function” (p.14). • The following devices, photoelectric sensor with semiconductor output, inductive proximity sensor, position switch on NO (Normally Open) contacting point, etc. are available for applying to the muting sensor.

Failure to do so can result in death or serious injury. • Do not use any reflective type or retroreflective type arrangement. • Installing multiple sets of this device produces a non-sensing area or causes mutual interference, which may result in death or serious injury. Sensor head diagnosis function (Only for ST4-C12EX) • Beam received / interrupted condition of the connected ST4-A□, or sensor fault can be checked by ST4-C12EX. When ST4-A□ is in the beam received condition, the muting input indicator (orange) lights up. However, the muting input indicator (orange) remains OFF if ST4-A□ is in the beam interrupted condition or ST4-A□ is not connected. The relation between addresses of ST4-A□ and the muting input indicator (orange) is as follows. Calculate the safety distance correctly, and always maintain the distance which is equal to or greater than the safety distance, between the sensing area of this device and the dangerous parts of the machine. If the safety distance is miscalculated or if sufficient distance is not maintained, the machine will not stop quickly before reaching to the dangerous parts, which can result in death or serious injury. 15 ST4-E.indb 15 2008/08/27 17:35:21 ST4 PRECAUTION FOR PROPER USE • The safety distance is the minimum distance that must be maintained between the ST4-A□ and the dangerous parts of the machine so that the machine can be stopped before a human body or an object can reach the dangerous parts. • The safety distance is calculated based on the equation described in the next page when a person moves perpendicular to the sensing area of the area sensor.

In case the intrusion direction is not perpendicular to the sensing area, be sure to refer to the relevant standard (regional standard, specification of the machine, etc.) for details of the calculation. The max. response time of the machine is from the point that the machine receives the halt signal from this device to the point that the dangerous part of the machine stops. The max. response time of the machine should be timed with the machine to be actually used.
