Overcurrent
protection:
In
the
running
state, the lower
control
continuously
detects that the
DC
motor
current
is
greater than the
rated current for
more
than
3
seconds.
When the machine enters the fault state,
the electronic watch buzzer sounds 9
times, and the fault code is displayed at
the same time. The rest of the area does
not display the content. After the fault
condition is maintained for about 10
seconds, it enters the standby state and
can be restarted.
Possible reason: Exceeding the rated
load, the current is too large, the system
is self-protected, or a part of the treadmill
is stuck, resulting in the motor not
turning, the load is too heavy, the current
is too large, the system is self-protected;
adjust the treadmill again. Start up and
run. There is also checking whether the
motor is running excessively or has a
burnt smell, replacing the motor; or
checking whether the controller burns
the smell, replacing the controller; or
checking whether the power supply
voltage specification is inconsistent or
low, and using the correct one. The
voltage specification is retested.
