Features
A Wide Range of Functions Allow Flexible Setting of the Monitoring Area.
Allows the Setting of a Protective Area with a
Radius of 4 Meters and a Warning Area with
a Radius of 15 Meters.
It is possible to set both a protective area with a maximum radius of 4
meters, which prevents the machine from operating when entry is
detected, and a warning area with a maximum radius of 15 meters,
which monitors and warns of people approaching the machine.
Because the OS3101 warns with indicators, sirens, and other means
that something has entered the warning area, it makes it possible to
prevent unintended stops. Two patterns of protective and warning
area combinations can also be set to meet various needs.
Warning area of
15 m max.
An Array of 16 Intrusion Indicators and an
LED Display Show the OS3101 Condition at a
Glance.
When the OS3101 detects an object entering the protective area, the
intrusion indicators immediately light in red. The positions of the lit
indicators from among the total of 16 indicators show the direction of
the intrusion. The LED status indicators and 2-digit numerical,
self-diagnostic display show the condition of the OS3101 with a single
glance.
OFF Output Indicator (Red)
Lights when an object is detected
entering the protective area.
ON Output Indicator (Green)
Lights while there is no object detected
entering the protective area.
Only the intrusion indicators for
the direction in which the
object has entered lights, so
the operator can confirm the
direction of entry at a glance.
Status/Self-diagnosis Display
Displays numerical codes to indicate the
status of the OS3101 during normal operation
or a lockout.
Sensing
angle of 180°
Protective
area of
4 m max.
Interlock Indicator (Yellow)
Lights while the OS3101 is in standby
mode waiting for start input. Blinks
when there is a malfunction.
Warning Output Indicator (Orange)
Lights when an object is detected entering
the warning area.
Intrusion Indicators
Light when the OS3101 detects
an object entering the protective
area.
The protective area is displayed
in 16 sections
(11.25° for each indicator).
Even Complicated Areas Can Be Easily Set
with Software
Highly flexible protective and warning areas can be set to match the
shape of the work area, allowing for the presence of machines and
other equipment. Area parameters are selected from semicircular,
rectangular, or polygonal.
A teaching function also allows the OS3101's scanning data to be
edited and registered as area setting data. These functions bring
considerable flexibility and ease to area setting.

Category 3 Safety Circuits Can Be Set
without Using the Controller
Two high-capacity PNP transistor control outputs allow direct
connection of output equipment such as safety relays and contactors
with rated current up to 625 mA at 24 VDC.
The OS3101 also features an external device monitor (EDM) that
makes it possible to configure safety circuits to the Category 3 level
without having to use the Controller.
Response Time from 80 ms to a
Maximum of 680 ms
The response time can be set for use in locations subject to special
conditions, such as spattering in welding stations. This reduces the
chances of the spattering material being mistakenly detected and
stopping the machine, thus helping to improve productivity.
