Control panel specification < LTS-2ACC700-4>    

Connection step:
Step 1: connected the light and controller (Reference to the picture on the right).
Step 2: if need the external trigger control, please connect the external trigger signal with the controller trigger interface.
Step 3: connect power (AC100-240V 50/60 Hz), press the red switch “-”, indicator light up, “o” uplifted, power on.
Step 4: If need to control the luminance by PC, please connect the PC with controller by RS232 data line in the power off status, then control by our demo program or the program you write yourself. Can set-up the each channel parameter manual when operated by serial port mode. That’s to say, the upper computer and controller all can set-up the parameter, no need mode swapping.

Trigger port setup < LTS-2ACC700-4 >    

This series controller is high level trigger. Total 4 group trigger ports, each has +,- mark. To input high level to +,- port can achieve the trigger function.

Trigger introduction: when output initial state is open mode, input high level 5-24V to trigger port, light close.when output initial state is off mode, input high level 5-24V to trigger port, light on.

Wire connection method of the external trigger signal

Sequence chart
Normal on mode (H1 mode):
When connect external trigger signal, trigger “+” input high level 5-24V “-” ground connection, light off.
Normal closed mode (H0 mode):
When connect external trigger signal, trigger “+” input high level 5-24V “-” ground connection, light on.

Specification: T1 is trigger delay time, T1≤80us  T3≤80us.
