Questions answered in JD-5(B)电动机保护器说明书 manuals
How do I adjust the setting current on the JD-5(B) protector?
Turn the two adjustment knobs clockwise to the stop, then power on the device. After the motor runs, slowly turn the right‑hand knob counter‑clockwise until the overload indicator just begins to flash, then turn it slightly clockwise; the knob position at which the overload light stops flashing for one minute is the initial setting.
