Notes
1: The operating voltage range is 85 to 264V AC of the input voltage.
2: Product items such as the switch, latch and stand are not included.
3: Trigger delay output is externally synchronized signal (100µs fixed pulsation width)

The product can be used as a conventional 12-V DC or 24-V DC power supply. Continuous and strobe
light options are available in either voltage.
2-2 Voltage Selector
12-V DC or 24-V DC output may be selected using the voltage selector on the back panel. However,
please make sure that the product is turned OFF before switching outputs. The voltage selector has
a locking mechanism that requires the switch itself be lifted up to change voltages. 12V DC output is
from connector L1, and 24V DC from connector L2. (When 12V DC is selected, 12V DC is also output
from connector L2.)
2-3 Continuous Light
Refer to other sections for the settings at # 2, # 3, # 5, and # 6.
DIP switch # 4 is not used for continuous lighting.
The # 5 setting depends on what was set when the power was turned ON. Changes made after the
power is turned ON are ignored.
Light control may be set within 256 levels combining coarse and rotary dials.
Continuous Light Control
Light intensity date: (Coarse x 16 + Fine) x 100/255 [%] (Note1)
Note: however, that the fine rotary dial controls the strobe delay time rather than light control when DIP
switch # 6 is ON. (Refer to 2-5)
The PULSE WIDTH switch does not work for continuous light.
Terminal Block ON/OFF Wiring

When the DIP switch # 5 is "OFF" and the ON/OFF signal is ON, the light turns on.
Conversely, when the DIP switch # 5 is "ON" and the ON/OFF signal is OFF, the light turns on.
ON/OFF input

2-4 Strobe Light
Refer to other sections for the settings at # 2, # 3, # 4, and 6.
Dip switch # 5 is not used in strobe light.
Light pulse width: 20, 40, 60, 80,100,140,180, 260, 400, 500, and 1,000µs or 3, 5, 8, 10, and 33 ms
(±10 ms).
Overdrive is activated with 3 to 4 times the light output for light pulse width of 1,000µs or less.
Strobe Lighting Control
When the light pulse width more than 3 ms, output voltage becomes for normal continuous light and
overdrive becomes disabled. Strobe light can be adjusted by 128 levels combining the coarse and
fine rotary dials.
Light intensity date: (Coarse x 16 + Fine) x 100/255 [%] (Note1, Note2)
Note: however, that the fine rotary dial controls strobe delay time rather than light control when DIP
switch # 6 is ON. (Refer to 2-5)
Notes
1: This is a theoretical value. It varies by loads and extension cables, especially around 0% as well
as 100% setting.
2: Strobe light resolution becomes half to 128 levels. (128 levels: 0,1,3,5,7,…,255)

2-6 External Control
External control mode may be selected by turning DIP switch # 2 (remote) ON.
The position of DIP switch # 3 determines whether bit-parallel or RS-232C be used for external control.
(1) Bit-parallel (DIP Switch # 3: OFF)
The15-pin D-sub connector on the back panel may be used for light control and ON/OFF control.
The rotary dials on the front panel are enabled when pin #9 (INT/EXT) is OFF. When pin #9 is ON,
light control and ON/OFF control are based on the following input status conditions.
Control Bit Configuration
Bit B1 B2 B3 B4 B5 B6 B7 B8 B9 B10 B11 B12
Construction (LSB) Light intensity data (0 to FF) (MSB) INT/ENT /WR OFF/

(2) Signal Logic
Data and control bits are negative logic bits (active LOW: maximum light intensity date when all bits are
LOW).
Use a driver IC, open collector, or other device to output the signal.
(3) External/manual control selector
This selector is used to switch to external control mode. (The rotary dials are disabled in this mode.)
External Control Mode Selection - B9 (INT/EXT)
Note: External control mode cannot be selected if DIP switch # 2 is OFF.
(4) Data Entry Sequence
Note: Data can be written in external control mode, but not in manual control mode.
(i) The light intensity data (B1 to B8) outputs in negative logic (maximum light intensity date with
all bits LOW).
(ii) It outputs the write bit (data written in 1 ms max.).

(5) Other I/O and Voltage Levels
The same ON/OFF signal (B11) and trigger signal (B12) that are input from the terminal block signals
can be input from the D-sub connector. With strobe light, the delay trigger signal (B13) that is used to
synchronize the external device set via RS-232C and the pulse light signal (B14) that is used to
confirm light are output at active LOW (5 V-CMOS level).
The pulse width of the delay trigger signal is always 100µs regardless of the pulse width of the trigger
input. The bit-parallel control signal is a 5V-CMOS level input (LOW: 1.35V max.; HI: 3.15V min.)

9-6 Serial Cables
Use 9-pin D-Sub serial cable in order to connect to external devices.
The serial cable should be a cross cable that is 15 m or shorter and fully shielded.
(We recommend: C06-09F-09F-CROSS-910 (3 m) [made by Misumi Group Inc.])
Noise will be introduced with a longer cable, resulting in possible transmission errors.
(A cable shorter than 3m is recommended)

General Precautions Regarding to External Control
1. Bit Parallel Input Voltage
The input voltage is 1.35V maximum for “LOW” and 3.15V minimum for “HI”. Faulty operation
may occur if a open collector output is two-stage, and a surge absorbing diode connected in series.
Because the residual voltage goes up as high as 1.5V when the power is turned on. Meanwhile,
the voltage may drop (pull-up resistance x IL) and “HI” can no longer be maintained if the leakage
current (IL) is high when the open collector turns off.
2. Controlling Output Units
(2-1) TTL/CMOS Output Units
The load voltage often ranges from 10.2 to 26.4V DC when sequencers use general-purpose
transistor output units. TTL/CMOS output units are ideal for this application because they operate
on +5 V and their residual voltage is guaranteed never more than 0.4 V.
(2-2) Separate Power Supply Control
A multi-bit output unit that is used to control both the PD power supply and the power system drive
unit makes the power system susceptible to noise because of the wiring involved. Provide a
separate power supply control unit to isolate the power supply from the power system.
3. Entry Sequence
The setup and hold time takes 100µs and the write pulse width is 1ms for the data entry sequence
described in this instruction guide. These figures, however, do not include the control circuit
ON/OFF response time or delay time variations between output channels. The PLC device and
photo coupler output for image processing also have relatively slow ON and OFF response times of
0.5ms and 1ms, respectively. Therefore, all the factors such as power supply setup time, hold time
with the output circuit response time, and delay time variations between channels, must be
considered in data entry.
4. Writing Light Intensity Data
There are some applications where light intensity data is written once when the power is turned on
and thereafter offer only lighting ON/OFF control. It is always safer to write light intensity data
every time even in those applications if the processing time allows it.
5. Wiring and Safety Measures
(5-1) Ground Wire
Wire the COM (GND) from the Output Unit directly to the power supply. Otherwise noise becomes
a factor and faulty operation is likely to occur. This happens because the GND level is raised by
COM current from somewhere other than the power supply if the COM (GND) is relayed by wiring it
to a terminal block and then branched it off for image processing, motor valve control, or the PD
power supply.
(5-2) Measures to Prevent Faulty Operation
If synchronization with motors, valves or other peripheral devices leads to faulty operation, then
move the external control line, lighting extension cable, or power supply away from the motor,
valve, or respective drive line causing the problem. Other possibilities for improving noise protection
include adding a ferrite core near the power supply unit or using shielded cable, twisted pair cable,
or cable with high EMI noise immunity.
