Chapter VModbusRegister Description

Chapter VIInstructions for use and setup

1. Interface Description

Main interface, displaying the current input/output status

DC voltage output setting page, on time (time from current state to fully open), off time (time from current state to fully closed)

2. Button Description

Long press on the main interface“ ”Key, enter the settings page, press“ ”Return to the main interface and save the current set parameters

On the settings page, short press“ ”The key can be used to switch between the DC voltage output settings and the thyristor output settings page.

On the voltage output setting page or thyristor output setting page, you can press“ ”The “ ”Left and right shift keys, select the parameters to be set.

By“ ”The “ ”Add and subtract keys to adjust parameter values.

3. Control instructions

When the module is set to register mode, throughModbusThe protocol writes the value of the corresponding channel register to adjust the brightness.

When the module is set to input linkage mode, it is switch input control

The switch input terminals, from right to left, areCOM，IN1，IN2，IN3，IN4

of whichCOMFor the public end,IN1，IN2For the voltage output control terminal,IN3，IN4Output control terminal for thyristor

equalIN1，IN2When the input is short circuited to the common terminal, the corresponding voltage output will control the output according to the set switching time0Change to10VOn the contrary, from10VChange to0V.

equalIN3，IN4When the input is short circuited to the public area terminal, the corresponding thyristor output control will control the light to change from off to the brightest according to the set switch time, and vice versa.
