Protection Area
2-3-1 Sensing Area
Be sure to install protection structure around the machine so that the operator must pass
through the sensing area of this device to reach the dangerous parts of the machine.
Furthermore, ensure that some part of the operator’s body always remains in the sensing
area when operation is done with the dangerous parts of the machine. Failure to do so can
result in serious injury or death.
Do not use any reflection type or recursive reflection type arrangement.
When connecting the sensor, use the correct combination of emitter and receiver (same
beam pitch and number of beam channels) and match their top-bottom orientation. Combining different types of emitter and receiver could produce a non-sensing area, which ma
result in serious injury or death.
Furthermore, facing several receivers towards one emitter, or vice versa, could produce a
non-sensing area or cause mutual interference, which may result in serious injury or death.
The sensing area is the zone formed by the sensing height of the sensor and the sensing
range between the emitter and the receiver. The sensing height is determined by the number
of beam channels. Furthermore, the sensing range can be 0.3 to 9m for
64 beam channels) and

2-3-2 Safety Distance
r
t
t
Calculate the safety distance correctly, and always maintain the distance which is equal to o
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 no
maintained, the machine will not stop quickly before reaching to the dangerous parts, which
can result in serious injury or death.
The safety distance is the minimum distance that must be maintained between the light curtain 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 (normal intrusion) to the sensing area of the area sensor.
Before designing the system, refer to the relevant standards of the region where this device is
to be used, and then install this device.
Furthermore, the equation described in the next pages is to be used only in case the intrusion
direction is perpendicular to the sensing area. In case the intrusion direction is not perpendicular to the sensing area, be sure to refer to the relevant standard (regional standard,

[When this device is used as a safety equipment for press machines in Japan]
[Standards for power press machine structure]
<Safety distance (reference)>
The following formula is for the safety distance given in the ‘Standards for power press machine structure’ (Ministry of Health, Labor and Welfare Notice No.116, issued December 26,
1977) based on the Industrial Safety and Health Law Provision 44. The following example
should be considered a reference value.
When actually installing the light type press machine safety equipment at the press machine,
follow the ‘Standards for power press machine structure’.
Formula (from Standards for power press machine structure, Provision 50)
D = 1.6 x (T
In the above formula, D, T
+ TS)
L
and TS respectively indicate the following values.
L
D : Distance between light type press machine safety equipment's beam-axis and danger limit
(danger source) (mm)
T
: Time from shielding of light to operation of press machine's sudden halting mechanism
L
[The device delay time (14ms)]
T
: Time from start of press machine's sudden stop mechanism to stop of slide (ms)
S
The safety distance (D) is calculated from the formula to determine the installation distance (A).
If the distance between the beam-axis and bolster front line exceeds a horizontal distance of
400mm, or if the distance is shorter than 400mm but the operator could enter between the
beam channels and bolster front line, install the auxiliary beam channels or an additional
guard.
<Calculation Example>
Setting the press machine's maximum stop time to 200ms.
D = 1.6 x (200 + 14)
= 342.4 (mm)
The safety distance in this case is D = 342.4 (mm).
<Installing the auxiliary beam channels>
Connecting the devices used for the main beam channels and auxiliary beam channels serially
is recommended. A series connection can prevent mutual interference.
(1) If installing the auxiliary beam channels when there is space between the main beam
channels radiated on the light type press machine safety equipment, installed with the
safety distance, and the bolster front line in which the operator could enter, install so that
the horizontal distance between the main beam channels and auxiliary beam channels is
200mm or less, and so that the horizontal distance between the bolster and the auxiliary
beam channels closest to the bolster is 200mm or less.
(2) Install the auxiliary beam channels so that it is horizontal to the bolster's front line, and so that
it is at a point approximately the same as the operator's waist.

[When this device is used as a safety equipment for press machines in Japan]
The emitter and receiver set installed to directly protect the total length of the press machine's
stroke length and slide adjustment range is called the ‘main beam channels’. Other emitters
and receivers installed for other purposes are called the ‘auxiliary beam channels’. When installing this device as the main beam channels, the beam channels with a protective height
larger than the total length of the press machine's stroke length and slide adjustment range
must be selected. If the distance between the center of the main beam channels and the bolster front line is 400mm or more, the auxiliary beam channels must be installed at 200mm intervals between the main beam channels and bolster to prevent operators from entering the
area.
Refer to ‘Policy on Press Machine Safety Equipment Control’ (Ministry of Health, Labor and
Welfare, Basic Publication No.446-2, issued on July 9, 1993) for details.
When using the auxiliary beam channels, set the auxiliary beam channels so that the
machine operator cannot stand between the machine and this device, and so that the
operator cannot go past this device's protective range and enter the machine's dangerous areas. Failure to use an auxiliary beam channels could result in death or serious
injury.
