The machine requirements
Installation
An OS32C is an electro-sensitive protective equipment designed to guard
personnel working around hazardous machinery.
Whether a specific machine application and the OS32C system installation complies with
safety regulations depends on the proper application, installation, maintenance and operation
of the OS32C system. These items are the responsibility of the purchaser, installer and user.
The administrator is responsible for the selection and training of personnel to
properly install, operate, and maintain the machine and its safeguarding systems.
An OS32C system should only be installed, verified and maintained by a qualified
person. A qualified person is defined as ”an individual who understands, is trained
on, and demonstrates competence with the construction, operation or mainte-
nance of the machinery and the hazards involved.” (ANSI/PMMI B155.1- 2006)
The guarded machine must be able to stop anywhere in its cycle. Do not use an
OS32C on a press with a full-revolution clutch.
The guarded machine must have a consistent stopping time and adequate control
mechanisms.
All safety-related machine control elements must be designed so that an alarm in
the control logic or failure of the control circuit does not lead to a failure to danger.
Do not use the auxiliary output or warning output for safety applications. A human body
may not be detected even if a failure of OS32C occurs, resulting in serious injuries.
The main unit must be securely mounted and its cable connectors must be tightly
attached.
Per the International standard IEC 61496-3, area scanners used in applications
where the angle of approach exceeds +/- 30 degrees with respect to the detection
plane, must use reference boundary monitoring (RBM) of the detection zone.
The OS32C must not be mounted behind glass or within a secondary enclosure. Failure to
do so will cause a reduction in detection capability, which can cause serious injury or death.
A protective mechanism must be installed to prevent a hazardous condition in the event of a
subsequent machine component failure. The OS32C does not protect against ejected flying
material.
A start switch to release interlock must be installed where an operator can
observe the monitored/guarded zone as a whole and cannot operate the switch
within the hazardous zone.
Make sure to remove any retro-reflector from the field of view of the OS32C when
in RBM mode.
If more information is needed, refer to the OS32C user’s manual (Z296-E1).
Others
Do not modify the main unit of the OS32C. Do not replace or fix any component of
the OS32C other than the ones specified in the user's manual. Doing so may result
in a failure of the device to function correctly.
If there is any damage to the window, replace it as soon as possible. Otherwise it
may result in a failure of the OS32C. Take preventive measures when performing
replacement work so that dust does not enter the OS32C.
Always detach all cables from the OS32C before replacing the scan window.
Otherwise the motor may start rotating, resulting in injuries.
The test outlined in this test procedure (See “Checkout and Test Procedure Log” in the OS32C
user's manual) must be performed at time of installation, according to the employer’s regular
inspection program and after any maintenance, tooling change, set up, adjustment, or
modification to the OS32C system or the guarded machine. Where a guarded machine is used
by multiple operators or shifts, it is suggested that the test procedure be performed at each shift
or operation change and also if there is a change in the OS32C operating mode or defined zone
sets. Testing ensures that the safety laser scanner and the machine control system are working
properly to stop the machine. Failure to test properly could result in serious injury to personnel.
If the OS32C is operated under automatic start, make sure that the machine stops
and does not restart as long as an object is detected in a safety zone. Check the
operation by placing a test piece into the safety zone. It is recommended to
perform the test at least after a shift change or 24 hours of operation.
If the safety system or the machine fails any of these tests, do not run the machine. Immediately
tag or lock out the machine to prevent its use and notify the appropriate supervisor.
System and zone status parameters monitored over EtherNet/IP are to be used for
diagnostic purposes only, and must not be used in safety-critical functions.
Measurement data monitored over EtherNet/IP are to be used for diagnostic
purposes only, and must not be used in safety-critical functions.
The window replacement procedure must only be performed by qualified personnel
in a clean environment at ambient temperature (5 to 35°C) to prevent the internal
optical surface from contamination. Make sure the inside and the outside of the
replacement window is clean and free from scratch, dust, and finger print.
The calibration procedure must only be performed by qualified personnel. Before
performing window calibration of the new scan window, make sure the window is
clean and free from scratch, dust, and finger print. The window calibration
procedure must be performed at ambient temperature 5 to 35°C. Failure to inspect
the window or set the proper environmental condition during window calibration
procedure may cause a reduction in the detection capability of the scanner.
Take precautions to prevent dirt, dust or debris from entering the sensor and I/O
block connectors.
It is recommended that this be done on a clean workstation as contaminants may
degrade the performance of the OS32C.
Adhesion of dust to the scan window may cause a false operation. The OS32C will
require periodic cleaning of the scan window and dust detection surface.
When transferring data from the PC to the OS32C and more than one OS32C is
connected to the network, it is necessary to visually check the diagnostic code on
the status/diagnostic display. It is recommended that the OS32C be installed in a
position where the status/diagnostic display will be visible.
Operation of the OS32C may be affected by light in the environment, such as
incandescent light, strobe light and light from a photosensor using infrared light.
Operation of the OS32C may be affected by substances in the environment, such
as fog, smoke, steam and other small particles.
Ensure the measurement report configuration matches the expected measurement
data format.
Before sending the changes to the sensor, verify that the safety parameters are
configured as intended for the application.

Safety Precautions
Make sure to follow all the safety precautions that are necessary to ensure safe
use of the product.
• Thoroughly read this installation manual and understand the installation,
operation checks, and maintenance procedures before using the product.
• Loads must satisfy both of the following conditions:
- Not short-circuited
- Not used with a current that is higher than the OSSD rating (250 mA sourcing)
• The main unit must be properly mounted with the proper mounting hardware.
• Do not drop the product, serious damage will occur.
•
Comply with all the laws, regulations, and standards of the country/region where the product is used.
• Dispose of the product in accordance with the relevant rules and regulations of
the country/region where the product is used.
Observe the precautions described below to prevent operation failure, malfunctions, or
undesirable effects on product performance.
■ Installation environment
Do not install the OS32C in the following types of environments:
• Areas where OS32C may be exposed to intense interference light, such as direct sunlight
• Areas with high humidity where condensation is likely to occur
• Areas subject to condensation resulting from severe changes in temperature
• Areas where corrosive gases are present
• Areas exposed to vibration or shock levels higher than in the specification provisions
• Areas where the product may come into contact with water
• Areas where the product may get wet with oil
• Areas where smoke and/or water vapor exists on the laser scanning plane
•
Keep the OS32C far enough from devices that generate high frequency noise or eliminate the noise.
• Be sure to route the OS32C cable separate from high-potential power lines or route through an exclusive conduit.
This is a class A product. In residential areas it may cause radio interference, in which case
the Responsible Person may be required to take adequate measures to reduce interference.
■ Wiring and installation
• Make sure to perform wiring while the power supply is OFF. Otherwise, the OS32C may fail
to operate due to the diagnostics function.
• Properly perform the wiring after confirming the signal names of all the terminals.
•
Do not operate the control system until 14 seconds or more after turning ON the power of the OS32C.
• Be sure to route the OS32C cable separate from high-potential power lines or through an exclusive conduit.
• When using a commercially available switching regulator power supply, make sure to
ground the FG terminal (frame ground terminal).
•
Sharing the power supply with other devices may cause the OS32C to be affected by noise or voltage drop. It
is recommended that the safety-related devices use a dedicated power supply, not shared with other devices.
■ Cleaning
Do not use thinner, benzene, or acetone for cleaning. They will adversely affect the product's resin parts and paint on the case.
■ Object detection
The OS32C has a configurable minimum object resolution of 30mm, 40mm, 50mm, or 70mm. It cannot
detect transparent or translucent objects, or objects with reflective surfaces, of less than 1.8% reflectivity.
When using more than one OS32C, mutual interference should be prevented. This
may require different scanner positions or physical shields to be installed.
Severe smoke and particulate matter may degrade the efficiency of an OS32C,
causing it to unexpectedly enter a Machine Stop state.
Use of mirrors or mirror-like objects in the protection plane must be avoided, as
they can hide part of the area to be monitored/guarded.
Additional guarding may be required to prohibit access to dangerous areas not
covered by the OS32C system.
Perform only the test and repair procedures outlined in the OS32C user's manual.
Perform the test procedure described in the OS32C user's manual at installation,
after maintenance, adjustment, repair or modification to the machine controls,
tooling or the OS32C system.
Additional measurement error resulting from reflective backgrounds may need to
be added to the measurement error of the OS32C
To use the protective function of the OS32C, a safety zone must be properly
defined and configured.
If the response time is changed, re-calculation of the safety distance is required. This
may require re-configuration of the safety zones or re-installation of the OS32C. If
the safety distance is not appropriate for the application, the machine may not stop
before contact with the hazardous part, resulting in serious injuries or death.
The activation of RBM Only mode will increase the response time. This additional time
must be taken into consideration when calculating the safety guarding distance.
To ensure a protection degree of IP65, DO NOT use this product without proper
sealing of the cable connector, I/O block, and scan window.
If the external zone switching device momentarily exceeds the configured number
of active zone set select inputs during the zone switch, an additional Zone Delay
may be incurred in the event that wiring of a zone set select input fails. The
external zone switching device must properly sequence so the configured number
of active inputs is not exceeded in order to guarantee that failed zone set select
input wiring will be detected within the normal Zone Switching Time.
If an insufficient Zone Delay is used for the actual worst case switching time of the
installation, the scanner might start monitoring the wrong zone during the switching period.
Also, if an insufficient Zone Delay is used for the actual worst case switching time of the
installation, there might be a fault condition during the zone switching period.
If tstart (switching start time) is configured without consideration of TmaxReaction
(total maximum reaction time), object detection within the new safety zone after
switching and turning OFF of the safety outputs may be delayed.
Monitoring zone parameters are subject to a number of constraints that include
projective consistency, maximum radius, and angle limits. As a result, an imported
zone may not correspond exactly to the zone defined in the file. The user must
visually verify the imported zone when the zone coordinate import process is
complete. Refer to Checkout and Test Procedure Log in the OS32C user's manual.
The installer is responsible for assessing the risk and to ensure that the zone of
limited detection does not create a safety hazard. If a hazard exists additional
countermeasure must be taken, this may require additional guarding measures.

If the OS32C is operating in automatic start mode, make sure that the machine
stops and not restart when the test object is in the safety zone. Check its operation
by approach of a test object into a safety zone. It is recommended that this test be
performed after a shift change or 24 hours of operation.
To test the OS32C’s detection capability, guide the test object along the perimeter of the safety detection
zone as shown in the figure below. The hazardous motion of the guarded equipment must stop immediately
(within the pre- determined accepted stop times). While in Automatic Start Mode, the OS32C MUST
remain in the machine stop state throughout the entire test.
To test the OS32C, use a test object with a diameter appropriate for the selected resolution.
(A test object does not come with the OS32C).
Note:
In this example, a semicircle is configured as 2m of
safety zone and 3m of warning zone.
Verify that all indicators and displays are operating properly and correspond to their defined functions of the
OS32C. Inspect the OS32C housing and the exit window for signs of damage or manipulation.
If the OS32C is used in a stationary guarding application, ensure that the safety zone(s) are clearly marked
on the floor. For mobile applications, make sure that the vehicle stops moving within the limits set in the initial
configuration.
If the OS32C fails any of these tests, lock out the guarded equipment and contact the factory supervisor
immediately.

Do not connect the OS32C to a power supply with more than 24VDC + 25% /
-30%. Do not supply AC power to the OS32C, this may result in electrical shock.
For the OS32C to meet IEC 61496-1 and UL 508, its DC power supply unit must
satisfy all of the following conditions:
• Within rated line voltage (24 VDC +25% / -30%)
• Complying with EMC directives (industrial environments)
• Double-insulation or reinforced insulation between primary and secondary
circuits
• Automatic return for overcurrent protection
• Output retention time of 20 ms or longer
• Satisfying output characteristics requirements of Class 2 circuit or limited
voltage/current circuit defined in UL508.
• Power supply complying with regulations and standards of EMC and safety
country or a region where OS32C is used. (Example of electrical equipment
in EU, a power supply must comply with EMC directives and the Low Voltage
Directive)
To prevent electrical shock, use double-insulation or reinforced insulation from
hazardous voltage (such as 230 VAC).
Cable extensions must be within the specified lengths, otherwise it may result in a
failure of the safety functions.
To use this product for a category 3 safety system, both safety outputs must be
connected to the safety system. Configuring a safety system with only one safety
output may result in serious injuries due to output circuit fault and a failure of the
machine to stop.
Protection of Cable at Installation:
Care should be taken when installing the OS32C cable. The cable must be
properly routed and secured to ensure that damage does not occur.
Functional Earth:
The OS32C system requires a functional earth connection.
Do not connect Functional Earth to a positive ground system. If it is connected to
positive ground, the guarded machine to be controlled may NOT stop, resulting in
severe operator injury.
Signal Connector Isolation:
The connectors used during installation must provide sufficient signal separation
in order to prevent a short circuit condition of the input power and system signals.

When wiring the OS32C to external devices, make sure to follow the color and
coding schemes per EN 60204-1.
Operation of the OS32C may be affected by light in the environment, such as
incandescent light, strobe light and light from a photosensor using infrared light.
Operation of the OS32C may be affected by substances in the environment, such
as fog, smoke, steam and other small particles.
The following considerations should be taken into account when determining the mounting location for
the OS32C. It is possible for ambient light to interfere with normal operation of the OS32C.
Ambient light interference DOES NOT lead to a loss of safety, it may, however, cause false nuisance
stops of the guarded equipment.
Some installations may require that the OS32C be mounted in direct exposure to ambient light. In these
situations you must assure that the separation between the scan plane of the OS32C and the light source
be greater than +/-5°.

The possibility exists that two OS32C may interfere with each other. To avoid this when using
multiple OS32C in the same location, please review the following mounting recommendations.
• Adjust the scanners to offset the scanning plane by tilting the OS32Cs.
• Adjust the scanners to offset the scanning plane by mounting the OS32Cs at different heights.
• Adjust the scanners to different scanning planes and additional sampling scans (response
time) on the OS32Cs.
• Install a barrier to block the direct path of possible signal crossing.
When installing the OS32Cs side by side, it is more effective to set their mounting heights
differently. When adjusting the OS32C tilted, it may be more effective to adjust the OS32C
downward depending on the condition of the outside light source (natural light or halogen light).
Use of a screen may increase the effect of reflection depending on its material. Select one with
matte black finish that is resistant to reflection.
