Fixed blanking function, floating blanking function
● With the fixed blanking function, this device prevents the person or object from entering into
the dangerous parts of the machine through the invalid sensing area. However, even though
this device can prevent the interference of the person or object into the invalid sensing area
with the fixed blanking function, there might exist the more space between the
SE4D
series
and already-existence object. Therefore, set the protecting structure so as not to exist any
space in the dangerous sensing area. Detecting human body in the sensing area could result
in death or serious injury.
● With the floating blanking function, this device changes the size of the minimum sensing
object of the
SE4D
series that is pre-set the function. When setting or changing the
function, calculate and measure the safety distance again, and check that the device has the
wider space than the safety distance between the dangerous parts of the machine and the
sensing area of the
SE4D
series. If the sufficient distance is not maintained, the machine will
not stop before its dangerous parts are reached, which can result in death or serious injury.
● Set and change the function of the device following the relative laws, regulation, and
standard without fail.
♦
Muting setting changing function
● The muting setting changing function temporarily invalidates safety function of the connected
devices. Confirm all of the applied laws and standards, and install or operate this device and
peripheral devices correctly. Failure to do so, the operator may suffer a serious injury.
♦
Environment
● Do not use a mobile phone or a radio phone near this device.
● Do not use this device in the following environments.
1) Areas with high humidity where condensation is likely to occur
2) Areas exposed to corrosive or explosive gases
3) Areas exposed to vibration or shock of levels higher than that specified
4) Areas exposed to contact with water
5) Areas exposed to too much steam or dust
♦
Wiring
● Be sure to carry out the wiring in the power supply OFF condition.
● All electrical wiring should conform to the regional electrical regulations and laws. The wiring
should be done by engineer(s) having the special electrical knowledge.
● Do not run the wires together with high-voltage lines or power lines or put them in the same
raceway. This can cause malfunction due to induction.
♦
Maintenance
● Clean this device with a clean cloth. Do not use any volatile chemicals.
♦
Other
● Never reassemble or remodel this device.
