E1
Communication
abnormal:The
communication
between
the
controller and the
electronic watch is
abnormal
after
power is applied.
Broken controller couldn’t working. Console display
fault code and the buzzer sounded 3 times.
Reason: the poor communication between controller
and
console.
Checking
each
connection
of
communication wire between console and controller.
Make sure each core is completely inserted. Check
the connection wire, if it was broken, change it.
E3
The motor line is not
connected properly
The treadmill stop working and enter a fault state when
the buzzer sounded 9 times. The console display fault
code while the rest areas do not display anything. If
console discovery normal state and enter standby state
after treadmill stop working, the treadmill can restart.
Reason: make sure the well connection of the motor
wire and connect the wire again. If the controller has
peculiar smell, replace the controller.
No signal of speed
sensor: a voltage from
controller is output to
the DC motor. The
motor speed feedback is
not
continuously
received for more than 3
seconds.
The treadmill stop working and enter a fault state when
the buzzer sounded 9 times. The console display fault
code while the rest areas do not display anything. After
maintaining the fault state for about 10 seconds, enter
the standby state and restart the machine.
Reason: no speed sensor signal is detected for 3
consecutive seconds, check whether the sensor plug is
not plugged in or damaged, plug it in or replace the
sensor.
E4
Ascending
by
self
learning
Check whether the induction line of the lifting motor is
plugged in properly and plug the connector again to
make it reliable. Check whether the AC line of the
lifting motor is plugged correctly, and the AC line of
the lifting motor is correctly numbered with the mark on
the controller. Check whether the connecting wire of the
motor is damaged or open, replace the connecting wire
or lift the motor; After checking all, press the learning
key on the control to learn again.
E5
Over
current
protection
˖
under the
running state, the down
control
continuously
detects that the DC
motor current is greater
than the rated current
+6A for more than 3
seconds.
The treadmill stop working and enter a fault state when
the buzzer sounded 9 times. The console display fault
code while the rest areas do not display anything. After
maintaining the fault state for about 10 seconds, enter
the standby state and restart the machine.
Reason: over - rated load leads to over-current and
self-protection of the system, or a certain part of the
treadmill is stuck, resulting in motor failure, over-load
and over-current and self-protection of the system.
Adjust the treadmill and restart it. Check whether the
motor has over-current sound or burnt smell when
running, and replace the motor; Or check whether the
controller has burnt smell and replace the controller; Or
check whether the power supply voltage specification is
inconsistent or low, and retest with the correct voltage
specification.
E6
Explosion
-
proof
protection:
abnormal
power supply voltage or
abnormal motor will
cause damage to the
drive motor circuit.
The treadmill stop working and enter a fault state when
the buzzer sounded 9 times. The console display fault
code while the rest areas do not display anything. After
maintaining the fault state for about 10 seconds, enter
the standby state and restart the machine.
Reasons: check whether the power supply voltage is
lower than 50% of the normal voltage, please retest
with the correct voltage specification; Check whether
the controller has peculiar smell and replace the
controller; Check whether the motor line is connected
properly and reconnect the motor line.
