Cautions on Handling Laser Light

1. IEC

 A semiconductor laser is used as the sensor's light source.

The laser is classified based on IEC standards (EN60825).

Wavelength 685nm

Maximum Output 1mW

Class 2

 Cautions

1) Be careful not to look directly at the laser beam or at its reflection from a
mirror surface.

2) Mount the sensor at a height above or lower than eye level so the beam will
not shine directly into eyes during operation.
The safety distance (Nominal Optical Harm Distance: NOHD) is approxi­mately 0.6m, but make sure the laser beam hits a diffusing reflector or an
absorbing body.

3) Laser beam emission can be stopped using the timing input supplied at the
input terminal (see TM1 and TM2 on page 3-5 and page 5-6). Or, select
"Open circuit" for the input operation of the timing input terminal (see page
5-34) to use the terminal for a remote interlock input.

4) The sensor head in this device is not equipped with a function that stops
laser radiation automatically when it is disassembled, so contact SUNX if it
breaks down.
There is danger of laser radiation if the head is disassembled for repair,
etc.

5) Do not use the device in operation other than that specified in this
Instruction Manual.
Caution – 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 contents of the warning label below carefully before use.
The warning label is affixed to the side of the sensor head. The English
warning label is packed with the sensor, so be sure to follow the instructions
printed on it during use.

Correct Handling

Note the following points when installing and using this product:

1. Warming Up Time

• Allow at least 30 minutes of warming up after turning on power to ensure
optimum conductance.

2. Use Environment

 Ambient Temperature, Humidity, Luminance

• Use this product in the temperature specification range (sensor head: 0 to
+45qC, controller: 0 to +50qC, compact console: 0 to +40qC). If the sensor is to
be stored, the temperature range during storage should be –20 to +70qC.

• The service life of a semiconductor laser depends on the ambient temperature
during use. If the product is used near a heat source, take measures to lower
the ambient temperature of the sensor head as far as possible. Because the
sensor itself emits heat, mount the sensor on a device having good heat
radiation.

• Use the sensor in a range of 35 to 85% RH relative humidity. Avoid use in
places that may be exposed to sudden temperature fluctuations causing
condensation.

• Use the sensor where luminance at the light sensor 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 during use.

 Environment

• If the external surge voltage exceeds 500V [± (1.2 × 50) µs unipolar full wave
voltage], the internal circuit may be destroyed. If there is danger of external
surge voltages exceeding 500V, install a surge protector between the power
supply and input terminal.

• Water or oil, or fingerprints, etc., on the sensor's emitter or receiver surfaces
refracts light, and dust or dirt cuts light, so keep the sensor clean at all times.
When cleaning these parts, wipe them off using a soft lint-free cloth or lens
cleaning paper.

• Set the sensor head so stray light such as sunlight or light with the same
wavelength, etc., does not enter the light receiver. If high accuracy is required,
install a light shielding plate or the like at the sensor.

9

• The sensor head is a waterproof device, but this does not mean that it can be
installed underwater or in places where rain falls. Due to their construction, the
controller and connectors are not dustproof, waterproof, or corrosion-resistant,
so do not use it in an environment where such features are required.

• Do not use this product in places where flammable or corrosive gases are
generated, where dust is excessive, where there is dripping water, where it is
exposed to direct sunlight or severe vibration or impact.

3. Noise Measures

• Do not run the sensor cable along (bundled in parallel with) other wiring, and
keep it at least 100mm from other wires. Run the cable so it is separate from
high voltage and power circuit lines. If running lines in parallel cannot be
avoided, shield the cable by running it through a grounded electrical conduit,
etc.

• For input signal lines and output signal lines, run them separately, not in parallel,
with power lines and power supply lines, keeping them at least 100mm apart. In
addition, keep all signal lines as short as possible when connecting them.

• Install this product as far away as possible from high-voltage lines, power lines,
high voltage device, wireless devices and machines which generate a large
starting and stopping surge.

• If a large amount of electrical noise is generated in the power supply, analog
output is affected. Use a noise filter or a noise dampened transformer.

• Use shielded cables for signal wires such as those for serial input and output
and I/O terminals to reduce electric noise, and connect the shielding wire to the
frame ground.

• It is easy for analog outputs to be influenced by noise, especially from external
sources, so use shielded wires, and keep wiring as short as possible.

• Use an exclusive class D ground based on the functional ground terminal, and
avoid grounding this device in common with other devices. If it is grounded in
common with other devices, the opposite effect may occur.

4. Insulation Resistance and Voltage Resistance

• Do not conduct insulation resistance and voltage resistance tests between the
power supply, input and output signals, and metal parts of the controller.

10

5. Power Supply

• Select a power supply with a ripple of 0.5V or less (P-P) and a current capacity
of 2A or more.

• When a commercial switching regulator is used, always use it with the frame
ground (F.G.) terminal connected to ground to avoid the influence of high
frequency noise.

• When using a transformer in the power supply, use an insulated transformer. If
an auto transformer (single turn transformer) is used, this product or the power
supply may be damaged.

• Do not turn the controller's power on again within 10 seconds after turning
power off.

• Use an insulated power supply with a built-in protective circuit to protect against
abnormal voltages from the power line.

• If a power supply without an internal protective circuit is used, be sure to supply
power via a protective element such as a fuse.

6. Instantaneous Power Failures

• If the duration of an instantaneous power failure is 10ms or less, operation
continues.

• If the duration of an instantaneous power failure is 10 to 45ms, one of the
following occurs:

(1) Operation continues.
(2) Analog output changes temporarily and BRIGHT and DARK indicators blink,

then the sensor recovers automatically.

(3) The same status as when the power supply is turned on occurs.

• If an instantaneous power failure lasts more than 45ms, the same status as
when the power supply is turned on occurs.

7. Installation

 Controller

• Install the controller unit based on "Heat Radiation Considerations" on page 2­2, assuring plenty of space around the unit. If it is installed in a manner that is
not based on instructions, it could cause malfunction due to the rise in
temperature, etc.

• If the controller is mounted on a control board, etc., internally where air circulation
is blocked, ambient temperature will rise due to heat generated by the controller,
so use forced cooling.

• If multiple units are installed in series, they can be installed against each other
only if they are installed vertically.

• Ventilation slits for heat radiation are provided in the controller. Provide adequate
space for radiating heat to dissipate, so as not to block the ventilation slits.

11

 Wire Connections and Connectors

• Connect all wiring securely based on the input and output circuit explanations
and according to markings. Ensure that wiring is correct.

• When connecting and disconnecting connectors and when making all connections,
make sure that controller power is turned off.

• When connecting and disconnecting connectors, take hold of the connector,
being careful not to exert undue force on cables.

• Be careful not to touch terminals or let foreign matter get in the connector when
disconnecting connectors.

• Be careful to keep from applying force to each of the cables near to connectors.
Do not bend cables near connectors because this breaks wires.

 Cables

• Do not pull the cable at a force more than

29.4N when routing the cable after fixing the

20mm or more

sensor head and controller. Do not allow
30mm or a shorter bending radius in the cable
path. During use, do not bend the cable at a
place within 20mm of the sensor head's cable

R30 or more

inlet.

• If the sensor head is to be used in a situation
where it is moved during operation, install it
so the cable will not flex during movement. If
flexure is necessary, use an extension cable
that can be replaced.

• Use only 1 extension cable for connection between 1 sensor head and controller.
Do not connect more than 2 extension cables or equipment may be adversely
affected by noise.

controller: 0 to +50°C, compact console: 0 to +40°C).

• Relative humidity exceeds 35 to 85% relative humidity.

• Luminance at the light receiver exceeds 3,000 lx (incandescent lamp).

• Places subject to sudden temperature fluctuations that could cause condensation.

• Corrosive or flammable gases exist in the atmosphere.

• Iron chip, dust or salt is excessive.

• The atmosphere contains benzene, paint thinner, alcohol, or other organic solvents, or
where a danger exists of strong alkaline substances such as ammonia or caustic soda
adhering to the sensor.

• Vibration or impacts are severe.

• Places exposed to direct sunlight.

• Water, oil, chemicals, etc., could contaminate the product.

• Loads are applied to the sensor head.

 Noise Considerations

• Mount this product as far as possible from high voltage lines, high voltage equipment,
power lines, power equipment, equipment that generates large start and stop surges,
and welders, inverter motors, and other equipment that generates electric noise.

• Mount this product as far as possible from equipment with a transmitter such as
amateur radio equipment.

• Do not let excessive static electric charges be applied to the panel surface since it
could destroy the LCD unit.

 Heat Radiation Considerations

• Do not mount this product on a heater, transformer, or other device that radiates large
amounts of heat such as high capacity resistors.

• If the controller is mounted internally on a control board where air circulation is blocked,
ambient temperature will rise due to heat generated by the controller, so use forced
cooling.

• Mount the controller with the following orientation to facilitate heat dissipation.

[Mounted vertically] [Mounted horizontally] [Multiple units mounted side by side]

2-3 Mounting the Controller

The controller can be mounted by fastening it with screws or by using a DIN rail.

 Mounting the Controller with a DIN Rail

The controller can be mounted or removed from a 35mm widt h DIN
rail (DIN EN 50022) in 1-touch operation.

[Mounting]

1.Hang the top on the DIN rail.

2.Push the bottom of the controller to fasten it on the rail.

[Removal]

1.Insert the blade of a flat-bladed screwdriver in the mounting lever.

2.Pull down the mounting lever.

3.Raise the controller and remove it from the rail.

 Mounting the Controller with Screws

• While referencing the external dimensioned diagram on page 10-3,
use M3 screws to fasten the controller. Do not tighten screws
beyond 0.5N·m.

• To avoid breakage inside the controller, do not insert the screw tip

3.5mm or more from the side of the case.

• Use only the 4 screw holes included on the side of the case.

2-3

CHAPTER 2 INSTALLATION

2-4 Mounting the Sensor Head

 Mounting the Sensor Head

• Fasten the sensor securely with M5 screws, using the 2 holes in the corners of the
sensor head. Limit tightening torque to within 1.2N·m.

• Install the sensor head with the relative position of the object adjusted to the type
(50mm/85mm, diffused reflection/specular reflection) of equipment used, referencing
the installation dimension drawing.

• It is possible to connect the sensor head (50mm) and another sensor head (85mm) at
the same time. The initial setting within the controller will correspond to the type of
equipment connected. When equipment of a different type is connected at the same
time, however, the upper/lower limit setting, hysteresis setting, and analog setting for
addition/subtraction operation will correspond to the type of equipment connected to
the head-1 side connector. When necessary, change setting contents.

• If the power supply is turned on with the connection changed (change in equipment
type: 50mm, 85mm, change in connection from 1-sensor head to 2-senso r head o r vice
versa) from that when controller setting contents are saved, setting contents are
initialized. If the connection is incorrect, turn off the power supply to return the
connection to that when the controller setting was saved, then turn on the power supply
again, returning setting contents to that when the controller setting was saved. Note
that setting contents are not initialized when equipment is replaced with an equivalent
type or when the number of units is increased/decreased.

• Operate the sensor head within the temperature specification (sensor head: 0 to +45ºC,
controller: 0 to +50ºC, compact console: 0 to +40ºC).

• Service life of a semiconductor laser depends on ambient temperature during use. If
the sensor is used near a heat source, take cooling measures to lower ambient
temperature of the sensor head. The sensor generates heat, so mount the sensor head
on a unit having good heat radiation performance. *

* When installing 2 sensor heads in parallel at a 20mm or less interval, mount each

sensor head on an aluminum or iron plate having a 200cm

2

surface area.

2-4

CHAPTER 2 INSTALLATION

• If the sensor is to be stored, temperature during storage should be -20 to +70ºC.

• Use the sensor at 35 to 85% relative humidity. Avoid use where sudden temperature
fluctuations could cause condensation.

• Use the sensor where luminance at the light sensor from incandescent lamps is 3,000lx
or less.

• Mount the sensor head so stray light such as sunlight or light with the sam e wavelength,
etc., does not enter the light receiver. Where accuracy is a factor, use with a shading
plate, etc.

• Do not mount the sensor head where flammable or corro sive gases are generated, dust
is excessive, water drips, exposure to direct sunlight is possible, or severe vibrations or
impacts occur.

• An alarm is output when the beam received is excessive or insufficient. The beam
received is determined each measurement cycle. When measuring a substance whose
beam received greatly fluctuates due to limited reflection beam, alarm output may
become unstable.

• Do not use output during start-up by turning on the power supply. Doing so may
change judgment output and alarm output during the period.

• Do not use analog output for several seconds right after turning on the power supply,
because analog output within ±5V (20mA or less) is sent during the period.

• Secure time of about 10 to 25 seconds, depending on the sampling period saved for
several seconds after turning on the power supply until the operation condition is
ensured (completion of start-up) (when the moving average count is turned off and
interference prevention function is turned off). This start-up time is increased by setting
the moving average count or by turning on the interference prevention function. It is
increased 1.2 to 2.4 times when the maximum moving average count is 32,768 times,
and to 1.4 to 3.3 times when the interference prevention function is turned on.

 Use an Insulated Power Supply with an Internal

Protective Circuit of Sufficient Capacity.

• Large current exceeding the rated current flows temporarily when power is turned on.
Use an insulated power supply with an internal protective circuit of sufficient capacity
(margin of 2A or more current capacity) to protect the circuit against irregular voltage in
the power line, and check power-on operation.

• An uninsulated type is used in the controller's regulator.

• If a power supply without an internal protective circuit is used, supply power to the
controller via a protective element such as a fuse.

 Switch the Power Supply On and Off at the Primary

Side.

• Switch the power supply on and off at the primary side (100V AC). If it is switched on
and off at the secondary side (24V DC), the controller's fuse may burn out.

 To Improve Noise Resistance

• Wire the controller, input device, and power device to run on separate systems.

• If noise from input and output circuits is a concern, it is recommended that power be
supplied separately for the controller and input and output power supplies.

CHAPTER 3 INPUT AND OUTPUT TERMINAL BLOCKS

 Consider the Power Supply Sequence.

• Consider the power supply sequence in which the controller's power supply is turned
off before input and output power supplies.

• If input and output power supplies are turned off before the controller power supply, the
controller will detect a change in input signal level and may malfunction.

• Do not turn the controller's power supply on again within 10 seconds after it is turned
off.

• It takes about 10 to 25 seconds ("Average number of samples" OFF and "Interference
prevention function" OFF) depending on the sampling period after power is supplied
until the controller is ready for operation (after completion of start-up). Do not use
output in the interval because output (judgment, alarm, and analog output) vary during
start-up.

 Instantaneous Power Failures

• If an instantaneous power failure lasts 10ms or less, operation continues.

• If an instantaneous power failure lasts 10 to 45ms, one of the following occurs:

(1) Operation continues.
(2) Analog output varies temporarily and BRIGHT and DARK indicators blink, then

the sensor recovers automatically.

(3) The state changes to reset.

• If an instantaneous power failure lasts more than 45ms, the state changes to reset.

 Use This Product Correctly.

• When wiring the power supply, turn the power supply off.

3-5 Grounding

 Grounding When Effects of Noise are Great

• Under normal use, this product has sufficient noise resistance, but in an environment
with particularly high noise levels, ground it securely.

 Use an Exclusive Ground.

•Use 2mm2or more wires and establish a class D ground with a ground resistance of
100: or less.

• Make the grounding point as close to the controller as possible, keeping the ground
wire distance short.

• If the laser sensor is grounded in common with another device, a reverse effect may
occur, so use an exclusive ground.

Supplementary Explanation

• When the sampling period is changed, measurement may be offset by several microns
up to tens of microns. The same applies when an extension cable is used or its length
changed.

• When the sampling period is changed, it is necessary to secure a time of 0.5 sec. to 3
sec., depending on the sampling period changed, until operation status is reached.
Except when the average number of samples is OFF, it is necessary to secure about
(Sampling period × Average number of samples). During this period, laser emission is
stopped, the laser emission indicator of the sensor head is turned off, and analog output
is in alarm output status. The measurement range indicator holds the status before the
sampling period is changed. The alarm output during this period becomes unstable.

• For changing the sampling period, setting the low or high pass filter, or setting the hold
mode other than NORM. see page 5-3.

• When 2 sensor heads are connected, the shortest sampling period is restricted using
specular reflection mode setting (page 5-16), a simplified optical filter (page 5-23),
emission adjustment setting (page 5-13) and data buffering (page 6-24) as shown in the
table below.

Restriction in shortest sampling period (operation with 2 sensor heads)

(*2) Buffering mode selected
(*3) The sampling period is set to 144µs when either is selected.
(*4) The sampling period is set to 200µs when either is selected.

• When sampling is set to shorter than the shortest period in the
above table or when the shortest sampling period is restricted
using specular reflection mode setting or optical filter, the
Warning screen at right is displayed, changing the period
automatically to the shortest sampling.

• When the sampling period is restricted using "Selection of data buffering mode" (page 6-

32), the mode cannot be selected because an error code (page 6-37) is returned.

• If the sampling period is increased for measurement of specular reflection, measurement
may not be done properly with the BRIGHT indicator and DARK indicator turned on at the
same time or with the DARK indicator turned on. Set the sampling period to a shorter
cycle again.

• When measuring in add/subtract operation or measuring the diffused substance under
specular reflection mode, the sampling period may exceed 100µs. Set the sampling period
to 144µs.

OFF, and set the average of calculation value, using the head 1.

• If the calculation value exceeds ±99.9999mm due to coefficient and offset settings, the
display on the compact console displays only 3 digits, and digits beyond 3 digits are
ignored. In this case, all digits for the alarm/judgment output screen can be displayed
(page 5-2).

• Use calculation so the result does not exceed ±999.9999mm. If the range is exceeded,
correct output is not obtained at the serial port.

5-2-9 Emission Adjustment

This device is designed so emission is optimized automatically based on the light reflected
from the substance measured, which is called "Luminous energy feedback". The device is
normally operated under this condition. A minimum of "Sampling period × 2" is required to
optimize luminous energy feedback. To measure a workpiece where light reflection may
vary excessively, such as a workpiece having many holes or a connector pin in which light­shielding status and light-passing status may be repeated, alarm status may continue due
to delayed feedback. In this case, luminous energy feedback may be stopped, and only the
measurement point with emission energy fixed to that required for the workpiece may be
measured at high speed.

It is possible for the controller to use the 2 modes below selectively. Select and use
measurement mode to suit the measurement type (diffused reflection/specular reflection) of
sensor head selected, based on the measurement object.

• Diffused reflection measurement : Used when measuring something without a mirror
surface or not transparent. It is initially set to "Diffused
reflection".

• Specular reflection measurement : Used when measuring a substance with a mirror
surface or that is transparent. In measurement in this
mode, change measurement mode and execute
"Save" (page 5-41) prior to use. Set the sensor head
by inclining it in the direction of specular reflection,
referencing the "Installation dimension" on page 2-5.

Supplementary Explanation

• If the sampling period is increased for measurement of specular reflection, measurement
may not be executable properly with the BRIGHT indicator and DARK indicator turned on
at the same time, or with only the DARK indicator turned on. Set the sampling period to
short.

{ When measuring a transparent substance such as glass, (specular reflection mode:

Front/Rear/Thickness):

• There is a limitation in measurable thickness. For general sheet glass, guideline
measurement objects are as follows, although it may be depending upon conditions such
as refractive index.

50mm specular reflection : Thickness of 0.5mm or more
85mm specular reflection : Thickness of 1.2mm or more

Check with SUNX for details.

• Conduct measurement with values both for surface and back within measurement range.

• Under luminous energy feedback (See "Emission Adjustment" on page 5-13), measure­ment may not be executable depending on surface treatment (plating, painting, etc.) or
the substance within the measurement range at the back of the transparent sheet. In this
case, stop luminous energy feedback, and measure with emission fixed.

5-2-23 Analog Alarm Delay

The Analog Alarm Delay is used with analog output during alarm when fixed output is
selected and executing fixed analog output (analog alarm) is not want in an instantaneous
alarm.
Analog output during an alarm is held up to the setting delay time. If alarm status continues
beyond the setting delay time, a fixed value, selected by analog output during the alarm, is
output for analog output. When hold is selected, analog output is held during the alarm
regardless of the delay time. It is also possible to add an alarm display and alarm output
delay to the analog alarm delay.

the input switches automatically to "Lump Input".

• To switch back to independent operation from add/subtract operation, it returns to the
state it was in before being switched to add/subtract operation.

• To input the timing, zero set ON/zero set OFF from the input terminal with the lump input
set, input these items only to either the sensor head 1 or sensor head 2.

• If an open input operation and lump input mode are selected, connect all input terminals
(TM1, I11, I12, TM2, I21 and I22) to an external isolated ground terminal while opening
terminals for either sensor head 1 or sensor head 2.

5-2-25 Calibration

Deviations in measurement may occur due to the color, material, and surface of the
measurement object. Correction for such deviations is called calibration.
In calibration, span and shift are set for each sensor head. There are 2 ways to set these
values. One is to conduct auto setting by moving a piece of workpiece past sensors and the
other is to input previously measured values directly.
Setting by moving the workpiece past the sensors.

* Before starting calibration either in automatic or input mode, check for the following settings:

Hold mode: NORM. Independent calculation formula: L1 + K1A, L2 + K2B
Zero set: OFF Independent calculation offset L1, L2: 0.0000mm
Timing: OFF Independent calculation coefficient K1, K2: 1.0000
Display hold: OFF Low pass filter: OFF
Sensor head operation: Independent High pass filter: OFF

 Automatically Setting the Span and Shift

In automatic calibration mode, designate start and end points to set offset.
Shift and span are automatically determined so the start point becomes "0" and the end
point becomes offset.

multiplied by (average number of samples)
until measurement becomes stable.

3. Determine the position where measure­ment should be "0".

Touch "Exec" on the start point screen where
measurement should be "0" (Example 1) or
where the workpiece is located at the other
extreme of displacement (Example 2). The
displayed measurement changes to "0" and

Supplementary Explanation

• During automatic calibration, span or shift exceeding the input range is adjusted to the

maximum or minimum value forcibly. After finishing automatic determination, use direct
input (see next page) to check settings. If the span or shift value is the maximum or
minimum value, possibility of incorrect calibration exceeding the setting range is highly
probable. Conduct automatic calibration again.

• If the automatic calibration setting screen is opened in display hold mode, measurement

having been valid at display hold mode selection is maintained and calibration cannot be
made correctly. Press

to exit from automatic calibration then conduct calibration

again. Display hold mode is automatically canceled when automatic calibration setting is
