3.operating instructions:
(1) wiring instructions
(2) digital encoder button operation
ln the default interface: ( the duty cycle is displayed by default)
short press-switch motor start and stop
Long press … to enter setup interface
Counterclockwise rotation … duty ratio decreases
Clockwise rotation … increase cycle

Under the setup screen:
Short press – select configuration parameters and toggle between lower limit cycle, upper duty cycle and duty cycleFrequency.the lower limit duty cycle display is “L ” + two digits, the upper limit duty cycle display is “H” + two digits or
“100”, and the frequency display of job is “F” + two digits.
Long press … exit setup interface
Counterclockwise Rotation – Corresponding Settings Are Reduced
Clockwise rotation-setting parameters increase accordingly
(3) back STOP port
3.3v level or key switch can be connected externally.Change the motor start l stop state when the key is closed or 3.3
v level is reduced.
