Introduction
Please read the manual carefully before using the controller. And please keep it for future use.
This controller can increase the brightness of normal 24V LED light by 3-4 times. It’s mainly used to control ma-
chine vision and industrial inspection LED light source.
1Features:
• Internal and external trigger input. High and low electrical levels can be used flexibly.
• For circuits control by individual, can set the lighting time from 10 to 990uS.
• Power cut memory, setting loch, fault detection, warning function.
• The lighting time and percentage can be manually controller by the knob on the front panel, and can also
be externally controller by PLC or machine vision devices.
• Control the lighting time precisely.
• Fast trigger response time.
• Be applicable to every 24V power input LED light source, 48V output, 60W total power consumption.

4.3 Note
• The control pack is made up of identifier, device Code, device ID, Command group and check SUM in turn.
• A command group can be made up of one or several commands, but at least one.
• One command is usually made by command code, channel No. and command data, but to some com-
mand, it may not have channel No. or command data.
• The control pack length is the bytes of device Code, device ID and all the commands, that is the bytes be-
tween length and check SUM.

• The check SUM is the sum of the bytes of identifier, length, device Code, device ID and all the commands.
• If the device ID of the control pack is 0xFF, it means that the command works on all the devices of all the
device ID. Or it only works on the device with the same device ID.
• If the Channel No. of the command is 0xFF, it means that the command works on all the channels of that
device. Or it only works on the specific channel.
• Only when the device receives the complete control pack and the check SUM is correct, will the device
deal with its command and make corresponding reply.
• Device will only make one reply even though there is number of commands in a control pack.
• Device reply correctly when all the commands of the control pack is correct; Reply incorrect for wrong
commands or data; No treatment for unrecognized commands.
• When the device ID is 0xFF, it means that this control pack is broadcast control pack. The device will
make corresponding treatment but no reply.
• The above device refers to every series control unit, for example this series is 02.
