LDLB/LDLB-IP Series
Bar Lights
Instruction Guide
Thank you for purchasing a CCS product. To ensure proper use of
the product, please read this instruction guide before use and keep
it for your future reference.
These LED Light Units feature integrated light control and ON/OFF control circuits.
The LEDs are driven with a constant-current system and the light is set to any of 100 levels with variable-current control.
You can change between Constant Lighting Mode and Overdrive Mode.
You can manually set the light intensity from the operating panel or set it with an analog input (0 to 10 V) from an external device.
You can daisy-chain up to three Light Units to provide power and externally control the light intensity of all of the Light Units together.
The LDLB-IP Series provides IP67 water resistance.

Connecting One Light Unit
Daisy-chaining Two or Three Light Units
Maximum Cable Length
Before you connect the Input Cable or Link Cable, make sure that the power supply is turned OFF. Making connec-
tions with the power supply turned ON may result in fire, electric shock, or breakdown in the Light Unit.
Handle the Light Units and connectors with care. Do not deform or damage the connectors.
Connect the cables correctly to the Light Units.
Connect a Sealing Cap to any output connectors to which a cable is not connected to maintain water resistance. The
Sealing Cap is connected to the output connector when the Light Unit is shipped.
If the Light Unit is not used for a long period of time with the cable disconnected, attach the Cap to the connector or take
other measures to maintain water resistance.
Observe the following precautions to prevent electrical shock and accidents from water entry.

You can daisy-chain up to three Light Units to set the light intensities or turn ON and OFF all of the Light Units together.
The maximum length of the 24-VDC power supply cable depends on the wire diameter, operating mode, and number of con-
nected Light Units. The maximum cable lengths are given in the following table.
One Light Unit Connected: The table gives the maximum length of the Input Cable.
Two or Three Light Units Connected: The table gives the maximum total length of the Input Cable and Link Cables.
Connect the Input Cable to the input connector and connect the leads on the end of the Input
Cable to an external device.
Connect the output and input connectors of the Light Units with Link Cables. Also connect the Input
Cable to the input connector and connect the leads on the end of the Input Cable to an external device.
Turn ON the power supply.
Turn ON the power supply.
Changing from Constant Lighting Mode to Overdrive Mode
1) Set the ON/OFF inputs from the external device to the status for turning ON the Light Unit in Constant Lighting Mode.
Refer to
7. ON/OFF Inputs
for information on the ON/OFF input.
2) Change the operating modes in order from the Light Unit that is farthest from the power supply.
(In the above figure, the order would be Light Unit A, Light Unit B, and then Light Unit C.)
Refer to
3. Names and Functions of Parts
for information on changing the operating mode. If the setting status of the
ON/OFF inputs is not correct, an overdrive error will occur when you change the operating mode. Also, if the order is not
correct, an overload error will occur.
Changing from Overdrive Mode to Constant Lighting Mode
1) Change the operating modes in order from the Light Unit that is nearest to the power supply.
(In the above figure, the order would be Light Unit C, Light Unit B, and then Light Unit A.)
Refer to
3. Names and Functions of Parts
for information on changing the operating mode. If the order is not correct,
an overload error will occur. The setting status of the ON/OFF inputs is not relevant.

LDLB Light Unit
External Circuit
Variable power supply
(0 to 10 VDC)
24 VDC
* You can adjust the light intensity with a variable power supply or a variable resistor.
*
If you use a variable power supply, use a power supply with a sinking
output of 3 mA minimum per Light Unit.
Pin 5
Pin 3
If you use a variable resistor, use the one specified below.
One Light Unit: 15 kΩ
Two Light Units: 10 kΩ
Three Light Units: 5 kΩ
Do not exceed an allowable difference of 20% in the overall resistance.
Note: According to product specifications, the light intensity that is set on
the operating panel may be used when the resistance is near the
maximum value.
If pin 5 (analog input) and pin 3 (common ground) are not connected on the input connector or if 13 to 24 V (maximum in-
put voltage: 26.4) is input, you can use the + and − switches on the operating panel to manually set the light intensity.
If 0 to 10 V is applied between pin 5 (analog input) and pin 3 (common ground) on the input connector, you can set the light
intensity to any of 100 levels with the voltage of the analog input.
The light intensity is displayed on the digital display between 00 and 99
(100 levels).
If you hold down the + or − key for more than 1 second, the value will
change faster.
The manually set light intensity is saved internally even after you turn
OFF the power supply or after you change to external light intensity
control with an analog input.
The light intensity is displayed on the digital display between 00 and 99 (100 levels).
To maintain the light intensity, continue to input a constant voltage. The light intensity that is set by the analog input is not
stored in the Light Unit.
Note: Depending on the number of connected Light Units and the cable length, different light intensities may be set for the same analog
input voltage.
Note: The digital display will show "--" if the light is turned OFF in Constant Lighting Mode. If you turn the light ON and OFF repeatedly over
a short period of time, the digital display may not display numbers correctly.

This connector is used to supply
power to the Light Unit and to input
signals to control the light intensity
and turn the light ON and OFF.
Note: There are no restrictions in the installation
direction. You can install the Light Unit up-
side down or in any other direction. Refer to
10. Dimensions
for the installation holes.
Using LDLB-IP-series
Light Units
If you do not use this con-
nector, always attach a
Sealing Cap to it to main-
tain water resistance.
Output Connector (M12 Socket)
If you daisy-chain Light Units, this
connector is connected to the input
connector on the next Light Unit with
a Link Cable.
If you daisy-chain Light Units, you can
supply power, control the light intensity
with an analog input, and use an ON/
OFF input to control all of the Light Units
together. You can also control the light
intensity of the Light Units individually
from the operating panels. You can con-
nect up to three Light Units.
A Link Cable (model: FECB-0.6-M12-
5M-5F, 0.6 m) is available as an option
(sold separately).
The LDLB-IP-series Light Units maintain IP67
water resistance when this Cable is connected.
Input Cables (models: FECB-M12-5F
Series, 1, 2, 3, and 5 m, flying leads) are
available as options (sold separately).
The LDLB-IP-series Light Units maintain IP67

The general relationship between the light intensity and the radiant quantity is shown in the following table.
Constant Lighting Mode
You can set the light intensity to any of
100 levels from the operating panel or with
an analog input from the input connector.
You can turn the light ON and OFF with an
ON/OFF input from the input connector.
Overdrive Mode
The mode indicator on the operating
panel will light. A larger current en-
ables a brighter light intensity (100 lev-
els) than in Constant Lighting Mode.
However, the light intensities that you
can set are restricted as shown below.
