Instruction Manual
For Safe Usage
● Manual Format
This manual uses the following headings to display important safety
information in order to prevent human injury and device damage.
WARNING
Failure to follow the instructions given under this heading may result in
human injury.
Do not use the controller with anything other than a 24 VDC pow er supply.
Doing so may result in fire, electrical shock, or device failure.
Note:Always ground the frame ground terminal or the ground terminal
when using a switching regulator. KEYENCE recommends the use
of separate power supplies in this situation.
● Installation location
Avoid locations such as the following when installing the CA-DC100:
• Locations where the controller is exposed to direct sunlight.
• Locations where the ambient temperature range exceeds 0 to +45
Locations prone to rapid temperature changes.
• Locations with poor ventilation.
• Locations where relative humidity exceeds 35 to 85% RH. Locations
subject to condensation.
• Locations where corrosive or flammable gasses are present.
• Locations where there is excessive dust, salt, or iron powder.
• Locations where the controller is exposed to splashes of substances
such as water, oil, or chemical agents.
• Locations where the controller is subject to direct vibrations or
mechanical shocks.
• Locations where the controller may be influenced by radiation noise or
static electricity.
• Separate the controller’s cables as far as possible from high-voltage
lines and power lines. Interference from such lines may result in nonstandard operation or device failure.
● Handling
•Avoid touching the controller during or immediately after use, since it
may become hot at these times. Doing so may result in burn injuries.
• Do not operate the unit after disassembling or modifying it. Doing so
may result in fire, electrical shock, or device failure.
• Do not look directly at the LED for extended periods of time. Doing so
may cause harm to your eyes.

CAUTION
Failure to follow the instructions given under this heading may result in
product damage (product failure, etc.).
Note:This heading is used to indicate common errors made by operations
in relation to device operation.
● General precautions
•Verify that this device is operating normally in terms of functionality
and performance before the start of work and when operating the
device.
• Implement safety measures as necessary to protect against possible
damage that may result in the event that this product fails.
• Proceed with care when modifying or disassembling the CA-DC100,
or when using it in a manner that falls outside of the ranges indicated
in its specifications, since KEYENCE is unable to guarantee device
functionality or performance in such situations.
• Use this product in combination with other devices only after careful
consideration, since the CA-DC100 may fail to satisfy its functionality
and performance capabilities as a result of the conditions and
environment in which it is used.
•Do not use the CA-DC100 with the purpose of protecting human
beings.
*We make every effort to ensure products reach our customers
without any damage. However, if you encounter any defective,
damaged, or missing parts, please contact your nearest KEYENCE
sales office (listed at the end of this manual).
WARNING
Turn off the device immediately in any of the following situations:
• When there is a foreign object or liquid such as water , oil, or a chemical
agent inside the device.
• When the device has been subject to excessive mechanical shock or
when the case has been damaged.
•When the controller emits smoke, an unusual smell, or a strange noise.
• When connecting and disconnecting cables, always s witch off the power
to the controller and any other devices connected to it. Failure to do so
may result in damage to the controller or to other connected hardware.
• When the controller becomes excessively dirty, apply a weak, neutral
detergent to a cloth and wipe away the dirt, then wipe the unit dry with
a soft cloth. Do not use benzene, thinners, or alcohol to clean the
controller. Doing so may result in the discoloration or deformation of
the controller case.
Installation
• Neither the cables attached to the LED illumination area nor extension
cables (sold separately) are flexible, so they are not suitable for
installation on moving parts where the cables must bear a load.
• Extension of the cable between the illumination and the controller will
result in decreased light quantity as a result of lowered voltage. Verify
adequate light quantity before use.
• Do not use this controller in combination with a non-KEYENCE LED
illumination device. Doing so may result in device failure.
Installation method 1
The controller may be attached to a DIN track.
When attaching or removing the controller, pull the fastener on the
rear of the controller in the direction indicated by the arrow.
Installation method 2
You can also use the mounting bracket (sold separately) to install
the controller. In this case use the screws that are provided on the
controller.
Mounting brackets (sold separately)
Use these screws

● Installation orientation
Do not use the
screws that come
with the mounting
brackets.
CAUTION
Continuing to operate the device despite such a problem may
result in fire, electrical shock, or device failure. Contact your
nearest KEYENCE sales office for repairs.
Do not install the controller in an orientation other than one of the 3
shown above. Leave a minimum of 20 mm of space on all sides of the
controller, and use caution when installing any other heat-generating
device (power supplies, etc.) to prevent the ambient temperature from
exceeding +45

CAUTION
LED elements are subject to a limited service lifetime. Because high
temperatures lead to degraded performance or damage, always use a
setting that generates the least amount compatible with application
requirements. Take precautions in order to avoid heat buildup, such as
the use of a cooling fan, installation using metal brackets , and intermittent
LED activation by means of external control input.
Note:The amount of light generated is unstable when the light adjustment
volume is set near 0%. This is normal and does not indicate a
problem with the controller. When using the controller with
continuous lighting, delay use after turning on the controller until the
amount of light generated stabilizes (this should take about 30
minutes).

Specifications
● Controller
* The LED illumination unit (sold separately) is designed for use in an
environment characterized by an ambient temperature of 0 to +40 °C
and relative humidity of 35 to 65% RH (no condensation).
•Environmental considerations differ for the controller and the LED
illumination unit. Make sure that each unit is installed in an appropriate
operating environment.
•
Condition for compliance with CE markings (EMC Directive: EN61326-1)
All cables connected to the controller (illumination unit, power supply,
external control input) should be less than 30 m in length. Be sure to
use the controller and illumination unit made by KEYENCE in
combination with each other.
● Precautions for LED
The CA-D, LED illumination device uses an LED light source. Abide by
the following precautions when using the unit.
• Do not look at the LED light source for a long period of time.
The LED used as the light source is classified into class 1 according to
IEC60825-1 standards. Basically the light beam of the LED is saf e , b ut
do not look at the LED for a long time.
• Do not disassemble the unit.
The unit does not incorporate a mechanism to stop the emission of the
LED when the unit is disassembled. Ne ver attempt to disassemble the
unit, otherwise you will be exposed to LED light.
