Alert Statements in this manual 2
!WARNING Make sure to install the MS4800 system at the safe distance from the hazard-
ous part of the equipment. Otherwise, the machine may not stop before a per-
son reaches the hazardous part, resulting in serous injury.
!WARNING Install a protective structure so that the hazardous part of a machine can only
be reached by passing through the sensor's detection zone. Install the sen-
sors so that part of the person is always present in the detection zone when
working in a machine's hazardous areas. If a person is able to step into the
hazardous area of a machine and remain behind the MS4800 system's detec-
tion zone, configure the system with an interlock function that prevents the
machine from being restarted. Failure to do so may result in serious injury.
!WARNING Install the interlock reset switch in a location that provides a clear view of the
entire hazardous area and where it cannot be activated from within the haz-
ardous area.
!WARNING The MS4800 system cannot protect a person from a projectile exiting the haz-
ardous zone. Install protective cover(s) or fence(s).
!WARNING To prevent personnel approach to dangerous part of the machine through a
zone disabled by the fixed blanking function, you must install a protective
structure to cover the whole disabled zone. Failure to do so may cause failure
of human body detection, resulting in a serious injury.
!WARNING You must ensure that a test rod is detected for all detection zones except
where fixed or floating blanking function is used. Failure to do so may cause
failure of human body detection, resulting in a serious injury.
!WARNING Detection capability gets larger if fixed or floating blanking function is used.
You must use the detection capability for fixed and floating blanking functions.
Failure to do so may cause failure of machine stop before reaching the
machine's dangerous part, resulting in a serious injury.
!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.
