the meter and the controller is
cut.
If yes, change the connector.
Check whether the joint has
been plugged in well.
Re-plug the joint.
E02
Explosion proof protection
Whether the supply voltage is
50% lower than the normal
voltage.
Use correct voltage standard
and retest.
Whether the electric machine
has been installed well.
Change the electric machine.
Whether the controller has a
bad smell.
Change the controller.
E03
Failure in inspecting the
motor signal for more than
15 seconds continuously
and speed sensor for 10
seconds.
Whether the distance and
location of the sensor and the
disc is correct, or the sensor is
installed right.
The sensor should be installed
right in the hole of the disc.
Whether the sensor wire has
been
open
circuited,
short
circuited or broken circuited.
Reconnect the motor interface
and examine the sensor wire.
Whether the sensor has been
broken down,
Change the sensor.
E04
Lifting learning or
self-inspection fails
Check whether motor wiring is
damaged to form open circuit
Re-insert the signal wire joint to
ensure that it is reliable
Check whether lifting motor's
AC
wires
are
properly
connected
Lifting motor shall be correctly
plugged according to marks on
its AC controller
Check whether motor wiring is
damaged to form open circuit
If yes, replace wires or replace
the lifting motor
Check whether the lifting motor
is damaged
If yes, change the lifting motor
Lifting motor fails in learning
Press the controller button for 3
seconds and relearn again.
E05
Over-current protection
Check whether the controller
matches with the standard of
the electric engine.
Change the electric machine or
