SECTION 12
Muting
!WARNING The muting and override functions disable the safety functions of the device.
You must ensure safety using other method when these functions are operat-
ing.
!WARNING Install muting sensors so that they can distinguish between the object that is
being allowed to pass through the detection zone and a person. If the muting
function is activated by the detection of a person, it may result in serious
injury.
!WARNING Muting lamps (external indicators) that indicate the state of the muting and
override functions must be installed where they are clearly visible to workers
from all the operating positions.
!WARNING Muting related time must be properly configured for its application by a suffi-
ciently trained and qualified person, and the person must have responsibility
for settings, especially when setting the muting time limit to infinite.
!WARNING Use independent 2 input devices for muting inputs.
!WARNING You must install MS4800 system muting sensor, and physical barrier, and con-
figure time settings for muting so that an operator should not enter hazardous
zone.
!WARNING Install the switch that activates the override in a location that provides a clear
view of the entire hazardous area and where it cannot be activated from within
the hazardous area. Make sure that nobody is in the hazardous area before
activating the override function.
