Overcurrent
protection:
Under
running
condition,
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 cause: 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.
