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.
Testing the Safety Area
The OS32C has the status/diagnostic display on the front, which indicates configuration/error status of
the OS32C.

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.

See also Product catalog for Warranty and Limitation of Liability.
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.
