Input Signal and Photocoupler
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.

* 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.

From the point where the photocoupler goes OFF, the Light Units are
turned ON for the set time (40 µs to 40 ms).
Trigger Logic Switch Set to LOW
From the point where the photocoupler goes ON, the Light Units are

Lighting Delay Time
The lighting delay time for lights connected to 24V LIGHT connectors depends on the power
consumption of the Light Unit. The lighting delay time for Spotlights connected to 24 HLV
LIGHT depends on the intensity of the Spotlights. Refer to the following graphs and tables.
* The data in the graphs show reference values when a Light Unit or Spotlight with a 5-m cable is used. (The values are for reference only.)
