2CAUTIONS ON HANDLING LASER LIGHT
●In order to prevent the accident by laser product and protect the users, JIS C
6802-2005 “Safety of laser products” was established based on the regulation of
IEC(InternationalelectrotechnicalCommission).Thisregulationclassieslaser
products according to the level of hazard, and provides the safety measures for
respective classes.
HL-C235CE, HL-C235CE-MKareclassiedas“Class3Rlaserproducts”accord-
ing to IEC 60825-1-2007 (JIS C 6802-2005) “Safety of laser products”.
●Laser hazardous class
ClassicationaccordingtoIEC60825-1-2007 (JIS C 6802-2005)
Class Model Description of hazardous evaluation
Class 1
- Safe under reasonably foreseeable conditions of operation
Class 1M
-
Safe under reasonably foreseeable conditions of operation, except for diverging
or large area beams when collecting optics used. Hazardous when collecting
optics used.
Class 2
- Visible beam, low power. Blink response of eye affords protection.
Class 2M
-
Visible beam, low power. Blink response of eye affords protection.
Hazardous when collecting optics used.
Class 3R HL-C235CE
HL-C235CE-MK Direct intrabeam viewing is hazardous, but risk is lower than for 3B.
Class 3B
- Direct intrabeam viewing is always hazardous.
Class 4
-
Highpower.Capableofproducinghazardousdiffusereections.
Capableofproducingskinburnsandrehazardous.
●WARNING label
In Chinese
In Japanese / English / Korean
<Label position>
●Install the product so the laser beam comes higher or lower than eye level in or-
der not to watch the beam directly during operation.
Laser safety distance (Nominal Ocular Hazard Distance: NOHD) is approx. 1.4m.
Thelaserbeammustbeterminatedattheendofitspathbyadiffusereectoror
an absorber.
●Please contact our company if the system breaks down. It is not equipped with a
function that stops laser radiation automatically during disassembling the sensor
head. The users therefore may be exposed to laser beam in disassembling the
sensor head.
●Whenthisproductis usedin China,afxtheChinesewarninglabel(accessory)
on the label in the product.
●
DonotusethesysteminthemannerotherthanspeciedinthisInstructionManual.
3EXPORT REGULATIONS BY JAPANESE GOVERNMENT
●Please follow the export control regulations required.
HL-C235CE and HL-C235CE-MK are not subject to export control regulations
under the condition that they are used combined with the non-pertinent controller
toexportcontrolspeciedbyForeignExchangeandForeignTradeLaw.
When they are combined with the pertinent controller to export control, they are
subject to the Law. In this case export admission by Japanese government is re-
quired before the product is to be exported or brought out of the country.

5CAUTIONS
Controller
●
It does not work properly in case connected to the controller ver. 1.**.
Forproperuse,connecttothecontrollerver.2.00orlater.
Connection
●
Turn off the power of controller before connecting or disconnecting the connectors.
●When connecting or disconnecting the connectors, be sure to hold the connector
area not to apply extra force to the cable.
●Be careful not to touch terminals or to let foreign matter get in the connector after
disconnecting connectors.
●Be careful not to apply force to around the connector of standard cable and ex-
tensioncable.Donotbendthecablesnearconnectors.Failure todo socauses
causes disconnection of the cable.
●When moving the sensor head during operation, install it so the cable not bend
bend during movement. Use replaceable extensions cable in case the cable
needs bend.
Wiring
●Do not run the sensor cable along (bundled in parallel) with other wirings. Keep it
at least 100mm away from other wires. Run the cable so it is separate from high
voltage and power circuit lines. If it is necessary to run the cable in parallel with
them, shield it by running through a grounded electrical conduit.
●Install the product as far away as possible from noise source such as high-voltage
lines, high-voltage device, power lines, power device, machines which generate a
large starting and stopping surge, welding machines and inverter motor.
●Do not pull the cable using a force more than
29.4Nwhenroutingthecablewiththesensor
head and controller fixed. At least 20 mm is
required from the cable connection to the bend.
The bending radius must be 30 mm or more.
●Use only 1 extension cable for connection be-
tween one sensor head and a controller.
20mm or more
R30mm or more
Warming up time
●Allow at least 30 minutes of warming up after turning on the power to ensure the
performance of the product.
Environment
●The life of the semiconductor laser depends on the ambient temperature during
use. When using the product near a heat source, take measures to lower the am-
bient temperature of the sensor head as possible. Mount the sensor on a device
having good heat radiation because the sensor itself emits heat.
Notes: 1) When installing 2 sensor heads in parallel at a 20mm or less interval, mount each sensor head on an alumi-
num or iron plate having a 200cm2surface area.
●Water,oil, orngerprintsonthe emittersurfaceandreceiver surfaceofsensor
headreectslight.Dustanddirtonthemblocklight.Keepthemcleanatalltimes.
When cleaning these parts, wipe them off using a soft lint-free cloth or lens clean-
ing paper.
●Install the sensor head so ambient light such as sunlight or light with the same
wavelength as laser beam should not enter the light receiver. If high accuracy is
required, install a light shielding plate or the like on the sensor head.
●The controller and connectors are not structurally dustproof, waterproof, or corro-
sion-resistant. Do not use the product underwater or in the rain.
● Donotusetheproductindustyplacesorthatexposedtoammableorcorrosive
gases, droplet, direct sunlight, severe vibration or impact.

7MUTUAL INTERFERENCE AREA (Unit: mm)
●When installing 2 or more sensor heads side by side, mutual interference occurs
if the laser spots from other sensor heads fall within the shaded areas in the right
gure.Installsensorheadssothelaserspotsfromothersensorheadsfalloutside
the shaded areas.
