６．Operation
(1) Connections
Confirm the power switch is OFF (on “0”side).
Connect the LED lighting unit to CH1 or CH2 or CH3 or CH4 output connector on front panel of the product.
Connect 3P socket of the AC power cord to power supply inlet on front panel of the product
and connect 3P plug of the AC power cord to outlet.
CAUTION
Connect an outlet with grounding. If it is not grounded, the power supply will not be ensured
electrical safety performance.
(2) Power on
Turn the power switch to ON (on “I”side). Set the intensity to minimum side to suppress the inrush current.
(3) Manual control
Light intensity is adjustable manually when the control switch on the front panel is set at “INT.”
(4) Remote control
When the Remote control switch on front panel is set at “EXT.”, external control input signal is available
through “RS-232C”or “TRIG. IN” connector on front panel.
(5) On/Off Control
It is possible to turn off the light by inputting “off”signal by remote control mode.
(6) Error Signal
Error indicator on front panel will be on if an error of LED lighting unit detected such as breaking of wire.
Error signal from external signal connector will be output at the same time.
It does not identify error of CH1 or CH2 or CH3 or CH4. Please check the lighting units.
This function does not detect the connection of lighting unit. To avoid signal malfunction, set the output minimum
level if the lighting unit is not connected.
This function works regardless of “INT./EXT.”mode.
(7) Noise reduction
Make sure to attach a Ferrite core clamp filter to AC power cord.

７．Control with External Signals
CAUTION
Use output signal cable of 3m or shorter.
Do not apply too high current and voltage.
Do not use external connector except SELV circuit with reinforced insulation or a
circuit with double insulation.

*Setting Procedures
With external trigger input connectors pins 1 to 4, select the channels (CH1 to CH2 to CH3 to CH4) where you want to
input an external trigger, and input trigger.
Trigger signals are input from the external trigger input connector in ON/OFF Mode and Strobe Mode in both Internal
Mode or External Mode.
ON/OFF Mode
The Light Units are turned ON or OFF according to the external trigger signal input.
Strobe Mode
The Light Units are turned ON for the set time after the external trigger signal input.
*Trigger Input Sequence Diagram
・A pulse width of ON signal shall be 10μs or more. The Light Units will be turned on for at least 40μs, even when the input ON
signal is less than 40μs.
・If another trigger is input before the Light Units turns OFF in Strobe Mode, the starting point of the reentered trigger is taken
as the start time and the strobe light continues for the set time from that point.
