3D PCB didn't
receive signals
from up limit
sensor within 40
seconds
1.Up & down limit sensor
is defective
2.Up&Down limit sensor
wire is disconnected
3.Rolling motor is dead
or rolling motor wire is
disconnected
1.Change up&down limit
sensor
2.Check whether
up&down limit sensor
wire is connect good
3.Check whether
rolling motor wire is
connect good or change
massage mechanism
when start
automatic
detection
