Applications
Features
Laser Beams Scan in 2-Dimensional Space to Constantly Monitor the Presence of Operators in
the MonitoringArea
The guiding principle in providing safety for operators is to prevent machines from operating whenever a person is inside the working area of a
robot or other machine.
The OS3101 Safety Laser Scanner uses 2-dimensional laser-beam scanning to detect whether an operator is present in the preset area by
monitoring reflected beams, in order to maintain operator safety.
Dependingon Work Details, Two Patterns Can Be Set for Two Different Area Combinations
Two different protective area and warning area combinations can be preset, allowing the OS3101 to respond to even complex changes in the work
environment.
The patterns can be switched using only the OS3101, without having to use the special Controller, to quickly meet the needs of various work steps.

OS3101
Features
A Wide Range of Functions Allow Flexible Settingof the MonitoringArea.
Allows the Settingof a Protective Area with a
Radius of 4 Meters and a WarningArea 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.
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-diagnosticdisplayshowthecondition of the OS3101 with a single
glance.
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 Usingthe 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.

Precautions for Safe Use

OS3101
14
The OS3101 is designed to be used with a 24-VDC, negative
(protective) ground electrical system. Do not connect it to a
positive (protective) ground el ectrical system. Connecting the
OS3101 to a positive (protective) ground electrical system may cause
the machine that is being controlled to fail to stop,
resulting in serious injury.
Do not connect any of the OS3101 lines to a DC power supply higher
than 24 V+20%. Also, do not connect to an AC power
supply. Failure to do so may result in electric shock.
For the OS3101 to comply with IEC 61496-1 and UL 508, the DC
power supply unit should satisfy al l of the following conditions:
xShould be within rated power voltage (24 VDC r20%).
xShould comply with EMC Direct ives (industrial environment)
xDouble or enhanced insulation should be applied between the
primary and sec ondary circuits.
xAutomatic recovery of overcurr ent protection characteristics
xOutput holding time should be 20 ms or longer.
xShould satisfy output characteristic requirements for class 2 circuit
or limited voltage current circuit dened by UL508.
xShould comply with the EMC, laws, and regulations of the country
or region where the OS3101 is used. (Example: In the EU, the
power supply should comply with the EMC Low Voltage Directive.)
Double or enhanced insulation should be applied between the
OS3101 and hazardous voltage sources (such as 230 VAC) to
protect against electric shock.
The cable extension length should be no greater than the specied
length. Otherwise, the safety func tions may fail to work properly,
resulting in danger.
When the OS3101 is used in a category 3 safety system, use both
control outputs to build the safety system. Using only one control
output may result in serious injury due to a malfunction in the output
circuit.
The protective area should be co rrectly dened and the parameters
related to the protective area should be correctly set in order to use
the protective functions of the OS3101.
When changing the response time of the OS3101, the safety distance
should be recalculated and the OS 3101 should be re-installed to
match the recalculated safety dist ance. Failure to do so may cause
the machine to fail to stop before an operator reaches the dangerous
area and may result in serious injury.
Do not allow the following types of light to shine directly on the
OS3101.
xIncandescent light
xStrobe light
xLight from optical sensors using infrared light
If the Window is cracked, broken, or otherwise damaged, replace it
immediately. Failure to do so ma y lower the degree of protection.
Also, when replacing the Window, take the necessary steps to
prevent dust or other particl es from entering the OS3101.
If the Dust Ring is damaged, replace it immediately. Failure to do so
may lower the degree of protection. Also, when replacing the Dust
Ring, take the necessary steps to pr event dust or other particles from
entering the OS3101.
To maintain the IP65 enclosure rating, make sure that there is no
foreign matter adhering to the seal s of the connectors, Window, or
Dust Ring, and that all screws are properly tightened.
Install the OS3101 securely.
When disposing of the OS3101, do so in accordance with the laws
and regulations for waste disposal in the country where it is used.
