Important Information for Equipment Safety
These products have been designed with full consideration of safety. However, incorrect usage of
the product may result in fire, electric shock, or other serious damages. Please ensure to follow the
conditions below.
Symbol Descriptions
Warning
Indicates that incorrect usage may result in serious injury or death.
Caution
Indicates that incorrect usage may result in injury or property damage.
Symbol Examples
symbols indicate caution (also including danger and warning). The example shown here
indicates a fire caution.
FIRE HAZARD
symbols indicate prohibited acts. The example shown here indicates prohibition to
disassemble.
DISASSEMBLY
PROHIBITED
symbols indicate instructions for specific actions. The example shown here indicates that the
power cord must be disconnected.
UNPLUG
Always use one of the following power cords.
100 to 120 V range: SVT or SJT type, AWG18, length: 3 m max., dielectric strength: 125 V min.
200 to 240 V range: H05VV-F type, AWG18, length: 3 m max., dielectric strength: 250 V min.
Plug the power cord directly into the wall
socket. Using a power strip or connecting many
loads from one electrical outlet may cause fire
or electric shock.
Do not disassemble or modify the product.
Doing so may result in fire or electric shock.
Do not touch the power cords or connect
peripheral devices during lightning. This may
result in electric shock.
If abnormal condition occurs such as fuming, heat, smell, noise, or so on, stop using the product
immediately, and turn off the power switch. A fire or electric shock may result if the product is kept used.
The product operates at a power supply
voltage of 100 to 240 VAC. The supplied
power cord, however, is for use with 100 V. If
the product is to be used at 200 V or above,
use an appropriate power cord.
Do not place product under direct sunlight or
in a high humidity environment. Doing so may
result in fire due to internal temperature rise.
Please use designated power sources with
stable voltage. Sharing a power source with
inverters, motors, etc. may cause malfunction.
Do not bundle product cables with high-voltage
lines or power lines. Doing so may cause the
product to malfunction. Keep the product cables
as far away from such lines as possible.
Make sure that connected lighting is within the
power rating of the product. Not doing so may
cause product failure.
Make sure that the length of the extension
cable is less than 5 m. However, if the cable
is too long, the light intensity will decrease
due to voltage drop caused by the DC
resistance of the cable.
Do not bend or jam cables when wiring
product. Doing so may cause product failure.
Before moving product, disconnect cables.
Damaging the cables may result in fire or
electric shock.
Make sure to hold and pull from the plugs
when disconnecting the cables. Not pulling
from the plugs may damage the cable and
result in fire or electric shock.

Warning
Turn off the power switch when connecting or
disconnecting the product and peripherals.
Otherwise it may cause fire and/or electric
FIRE HAZARD
shock.
Do not touch the product with wet hands.
Doing so may result in electric shock.
DISASSEMBLY
PROHIBITED
Make sure that the product is free of moisture
or any liquid. Exposure to water may result in
fire or electric shock.
SHOCK HAZARD
Caution
Be sure to ground the product before using it.
Not doing so may result in electric shock.
FIRE HAZARD
Always place product on a stable and flat
location. Not doing so may result in the
product falling or toppling, which may cause
FIRE HAZARD
bodily injury.
Do not use lighting that is not manufactured
by CCS. Doing so may cause product failure.
Use of non-CCS lighting voids the warranty
MANDATORY
on the product.
ACTIONS
Do not use user-made cables.
Doing so may cause product failure.
MANDATORY
ACTIONS
Do not disconnect power cord or disassemble
product while operating.
Doing so may cause product failure.
MANDATORY
ACTIONS
Do not drop or subject the product to
impact. Doing so may cause the product to
malfunction.
MANDATORY
ACTIONS
To avoid product surface discoloration or
deterioration, do not wipe product with
volatiles such as paint thinner or benzene.
MANDATORY
ACTIONS
Use a dry cloth to remove dust or other foreign
matter from the plug electrodes. Failure to do
so may result in fire.
MANDATORY
ACTIONS
When mount the unit in a system rack or case,
the portion of the screws penetrating the case
must be less than 5 mm long. If this portion
MANDATORY
is longer, internal components may be short-

Operating Instructions
1
Connection
Turn OFF the power switch on the front panel and then connect the AC cord to the AC inlet on the rear of
the product and to wall socket.
Connect the LED light to the output connector, and the external control cable to the external control
connector, in the rear of the product.
2
Power ON
Turn On the power switch.
3
Trigger mode selection
Set the trigger mode selection switch on the front panel to the desired mode.
[ Trigger Int ] Internal trigger
The internal trigger generates a trigger every 1.42 ms inside the control unit regardless of the trigger input signal.
Note: It appears to be not strobing light to human eyes. It is used for pre-set, such as LED light positioning and connection.
[ Trigger Ext ] External trigger
An external signal is used for the trigger.
4
Setting the light pulse width
[ Pulse Width ]
Set the light pulse width to between 10 and 990 us (in 10 us steps) using the light pulse width setting
switch on the front panel.
Note: This setting is valid only when an external trigger is used.
5
Light intensity
[ Control ]
The light intensity can be controlled between 10% and 100% (in 10%
steps) of the light pulse width set on the light pulse width setting switch.
(1) Manual intensity control
The light intensity is manually controlled with the intensity
control knob on the front panel.
(2) External intensity control
To use external intensity control, set the Control INT/EXT
switch on the external control connector to EXT (Low). Refer
to the table on the right and set control 1 through control 8.
Lighting time = Light pulse width [(00 to 99) x 10 us] x Light intensity (10 to 100%)
Note: Light may not be emitted if the lighting time is 10 us or shorter.
6
Trigger signal
The signal current of 5 mA or less must be supplied through open collector, high-speed photocoupler, or
driver IC. The light pulse width must be 20 us or longer. It is not required to install a current limiting resister
because the PTU2 Series is equipped with a constant current diode (applied voltage: 24 V max.).
Note: The trigger input signal is valid only when the following equation is satisfied:
Light pulse width/Trigger cycle ≤ 0.07

Overcurrent protection
The PTU2 Series will forcibly turn OFF the output when the current consumption of the lighting exceeds

the values in the table below. The Error indicator lamp (red) on the front panel will also start blinking.
The output interruption will not be canceled until the control unit is restarted.

to prevent the light from burning up even if
wrong operation causes repetitive trigger
signal inputs. A trigger input that is input
in the interval less than 14.2 times the set
