Trigger Input Sequence Diagram
If another trigger is input before the Light Unit 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.
ON/OFF Mode
Trigger Logic Switch Set to HIGH
The Light Units turn ON when the photocoupler is OFF, and OFF when
the photocoupler is ON.
Strobe Mode
Trigger Logic Switch Set to HIGH
From the point where the photocoupler goes OFF, the Light Units are
turned ON for the set time (40 µs to 40 ms).

* The LED Light Unit will turn off by OFF signal sent by either
trigger signal input
or
Ethernet communications
.
* The LED Light Unit will turn on by ON signal sent by either
trigger signal input
or
Ethernet communications
.
The input signal from the external trigger input connector can be used to control
the photocoupler inside the Unit to turn the LED Light Units ON and OFF or to
control strobe timing.
The operation depends on the setting of the trigger logic switch.

()
With the external trigger input connector pins 1 to 3, select the channels (L1
to L3) where you want to input an external trigger, and input the trigger.
Trigger signals are input from the external trigger input connector in ON/OFF
Mode and Strobe Mode in both Manual 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 ignal is input.

Troubleshooting
When detecting the error during external control, command will be received as
acknowledgement for checking status (over current confirmation) command “C”.
If the consumption current of Light Units exceeds 107% higher than the
rated current, the overcurrent protection operates and stops the output.
OCP will be displayed on the digital window.
Please check the rated current of Light Units and connect the Light Units
under the rated current of this control unit.
Please press Setting Switch for over a second to reset the OCP error.
(OCP error can be reset by rebooting.)
Setting Switch
Press over a second
* Immediately after the error, occurrence of an error will be noticed only one time by
using UDP protocol. Notify data is the same as checking status (over current
confirmation) command “C”.
For details, refer to
7. Control with External Signals
.
* When operating trigger signal input and Ethernet communications at same time in ON/OFF mode.
When Trigger logic switch is at HIGH: if ether controls setting to OFF setting, Light unit will be turned OFF
When Trigger logic switch is at LOW: if ether controls setting to ON setting, Light unit will be turned ON
