Correct Handling
Note the following points when installing and using HL-C2 Series.
Installation Environment
■Do not install the product in the following conditions.
• Where the ambient temperature, ambient humidity or ambient illuminance
of beam receiving surface is beyond the range of specifications
(Refer to “Use Environment”.)
• Where dew condensation occurs due to rapid temperature change
• In an atmosphere of corrosive gas or flammable gas
• Where covered or filled with dust, iron powder and salt
• In an atmosphere which is likely to be exposed to organic solvent such as
benzene, thinner or alcohol, or to strong alkaline materials such as ammonia
or sodium hydroxide
• Where heavy vibration or impact is applied
• Where direct sunlight is received
• Where water, oil or chemicals splashes
• Where load is applied to the product
Use Environment
■Ambient Temperature, Humidity and Illuminance
Ambient temperature
・Use the product with the temperature specification ranges ( Chapter 8
“Specifications”).
Sensor head ：0 to 45°C
Controller ：0 to 50°C
Compact programmable display ：0 to 50°C
Store the product with the following specification ranges.
Sensor head ：-20 to 70°C
Controller ：-20 to 70°C
Compact programmable display ：-20 to 60°C
・The life of the semiconductor laser depends on the ambient temperature
during use. When using the product near a heat source, take measures to
keep the ambient temperature of the sensor head as lower as possible.
Mount the sensor on a device having good heat radiation because the sensor
itself also generates heat.
* As for HL-C211□□(-□□), when installing two sensor heads in parallel with a distance
of 20mm or less, each sensor head should be mounted on aluminum or iron which
surface area is 200cm2or more.

Preface
9
Ambient humidity
Use the sensor within a range of 35 to 85% RH.
Avoid using it in places that may be exposed to dew condensation due to rapid
temperature change.
Ambient illuminance of light receiving surface
Use the sensor in locations where illuminance from incandescent lamps is
3,000 lx or less.
■Power Supply Voltage
The power supply voltage should be within the rated voltage range of 21.6 to
26.4V DC.
■Environment
• The internal circuit may be broken when the external surge voltage exceeds
500V [± (1.2×50) µs unipolar full wave voltage]. If there is danger of
external surge voltages exceeding 500V, install a surge absorber between the
power supply and input terminal.
• Keep the emitter surface and the receiver surface clean, not to attach light
refractors such as water, oil and fingerprints, or light blockers such as dust
and dirt. When cleaning these parts, wipe them off using a soft lint-free
cloth or lens cleaning paper.
• Install the sensor head at where extraneous light (such as sunlight or light
which has the same wavelength as laser beam) do not enter the receiver. If
high accuracy is required, install a light shield plate or the like on the sensor
head.
• Do not use the product in dusty places or that exposed to flammable or
corrosive gases, droplet, direct sunlight, severe vibration or impact.
Protective Structure
• The sensor head has protection against immersion, while the controller and
connectors are not structurally dustproof, waterproof, or corrosion-resistant.
Do not use the product underwater or in the rain.

Preface
10
Warming Up Time
Allow at least 30 minutes of warming up after turning on the power to ensure
the performance of the product.
Measures to Noise
• 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.
• Install the product as far away as possible from wireless device that has a
transmitter such as amateur radio device.
• The LCD display breaks if excessive static electricity is applied on the panel
surface of compact programmable display.
• Do not roll up the sensor cable (bundle in parallel) with other wirings. Keep
it at least 100mm away from other wires. Cables should be separated from
high voltage and power circuit lines. If it is unavoidable, shield it by
running through a conductive material such as grounded electrical conduit.
• For input signal lines and output signal lines, run them separately, not rolled
up with the power line and power supply line. Keep them at least 100 mm
apart. All signal lines should be connected as short as possible.
• Analog output is affected if a large amount of electrical noise arises in the
power supply. In this case, use a noise filter or a noise dampened
transformer.
• For signal lines for RS-232C or for I/O terminals, use shielded cables and
connect the shielding wire to the frame ground (F.G.) to reduce electric
noise.
• Analog outputs is likely to be influenced by noise, especially by external
noise. Use shielded wires and wire them as short as possible.
• Use an exclusive class D frame ground and avoid sharing the ground with
other devices. This may produce an opposite effect.
Insulation Resistance and Voltage Resistance
Do not conduct insulation resistance tests and voltage resistance tests among
the power supply, I/O signals, metal parts of the controller and sensor head.

Preface
11
Power Supply
■Power Supply
• Select a power supply with a ripple 0.5V or less (P-P) and a current capacity 2A
or more.
• When using a commercial switching regulator, be sure to ground the frame
ground (F.G.) terminal to avoid the influence of high frequency noise.
• When using a transformer in the power supply, be sure to use an insulated
transformer. The product or the power supply may be damaged if an auto
transformer is used.
• Use an insulated power supply that incorporates a protective circuit to protect
against abnormal voltages from the power line.
• When using a power supply that does not incorporate a protective circuit, be
sure to supply power through a protective element such as a fuse.
■Power Supply Sequence for Controller
• Arrange the power supply sequence so the controller turns off prior to the I/O
power.
• If the I/O power turns off prior to the controller, the controller detects the change
in level of input signals and this may cause wrong operation.
• Leave an interval for at least 10 seconds between turning off the controller and
turning on the power again.
• It takes about 40 to 50 seconds from power-on to operating state (start up
completed), depending on the settings saved. No outputs are determined
during startup. Do not output anything during the period.
• During startup, -10.8V of analog voltage and -5mA of analog current are output.
• Do not turn off the power while saving the settings. In the worst case, the
system of controller is destroyed and may fail to restart.
Instantaneous Power Failure
If an instantaneous power failure occurs, the system operates continuously, or
goes to the same state as power-on state, depending on the duration of power
failure.Do not use the system in the environment where an instantaneous power
failure occurs.

Grounding
■Ground the device when noise influence is large
• Under normal use, the product has sufficient noise resistance. In an
environment with particularly high noise levels, however, ground it securely.
■Use an exclusive ground
• Use wires of 1.5 mm2or more and establish a class D ground with a ground
resistance of 100Ω or less.
• Make the grounding point as close to the controller as possible, keeping the
ground wire distance short.
• Use an exclusive ground. Sharing the ground with other devices may
produce an opposite effect.
• The connector housing for the sensor head case and sensor cable is
connected electrically to the frame ground (F.G.) terminal of the controller
terminal through the sensor cable.

Precautions for positive ground environment
The GND terminals of 24VDC (-) and USB port, SG of RS-232C, and
COMMON terminal (-) of the input / output circuit are connected inside the
HL-C2. The FG terminal, USB port connector shell, RS-232C connector shell
and Ethernet connector shell are also connected inside the HL-C2. Make sure
that there is no potential difference from externally connected devices such as
a PC and PLC.

If the HL-C2 is used in a positive-grounding environment, power supply
(24VDC) can become short-circuited via the GND terminal of PC or USB,
thus resulting in a malfunction.
・Do not ground the positive (+) terminal of the HL-C2.
・When grounding the positive side of the power supply (24V DC) to the
equipment, use a separate power supply (24V DC) for the HL-C2 and
insulate the HL-C2.

Installation
■Controller
・Install the controller unit according to “1-3 Installation Method”, assuring
plenty of space around it. If it is installed in a manner other than specified,
failures may occur due to temperature rise.
・If the controller is mounted internally on the place where air circulation is
blocked such as in a control board, the ambient temperature will rise due to
heat generated by the controller. In such case, forced cooling is required.
・Vent holes for heat radiation are provided at the top and bottom of controller
unit. Provide adequate space for heat radiation, not to block the holes.
■Wire Connections and Connectors
• Connect all wirings securely according to the explanations for I/O circuit
and description on the unit.
• 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 objects get in the
connector after disconnecting connectors.
• Be careful not to apply force to around the connector of sensor head cable
and extension cable.Do not bend the cables near connectors, which causes
disconnection of the cable.
• When moving the sensor head during operation, install not to bend the cable
during movement. Use replaceable extensions cable where the cable needs
to be bent.
■Cable Extension
• Do not pull the cable with a force
more than 29.4N when wiring the
cable when the sensor head and the
controller are 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 one extension cable for
connection between one sensor head
and a controller.
20mm or more
R30mm or more

Cautions on Handling Laser Light
JIS/IEC/GB/KS
■Semiconductor laser is used as the light source of sensor
The laser is classified based on JIS (JIS C 6802:2014) and IEC (IEC
60825-1:2014), GB (GB 7247.1:2012), KS (KS C IEC 60825-1:2013)

■Cautions
1)Be careful not to directly watch the laser beam or its reflected light from a
mirror surface.
2) Install the sensor so the laser beam comes higher or lower than eye level in
order not to watch the beam directly during operation.
Laser safety distance (Nominal Ocular Hazard Distance: NOHD) is approx.
0.4m for HL-C203B
□
(-MK) and HL-C205
□

(-MK) and HL-C211
□
(-MK), is approx. 1.4m for
HL-C235BE(-MK) / HL-C235CE(-MK), HL-C235CE-W(MK). The laser beam
must be terminated at the end of its path by a diffuse reflector or an absorber.
3)Laser beam emission can be stopped by using the laser control input
terminal. ( “2-1 Functions and Arrangement of I/O Terminal Block”)
*
Use the interlock control input terminal when using as an emergency stop
circuit for safety. Release the short circuit by short bar to stop laser emission.
4)Please contact Panasonic Industrial Devices SUNX if the system breaks
down. Laser radiation is not automatically stopped during disassembling
the sensor head. The users therefore may be exposed to laser beam in
disassembling the sensor head.
5)Do not use the system in the manner other than specified in this USER’S
MANUAL.
You may be exposed to hazardous laser radiation if the device
is
controlled or adjusted in procedures not specified in this
manual.
6)Read the descriptions of the warning label carefully before use.
The warning label is affixed to the side of the sensor head. The Japanese and
English warning labels are packed with the sensor. Use them as needed.
