Level
Err43
Up limit signal
abnormal
Subcode 101: The up limit
switch acts when the elevator
is running in the up direction.
Subcode 101:
● Check the signal feature (NO, NC) of the
up limit switch.
● Check whether the up limit switch is in
good contact.
● Check whether the limit switch is
installed at a relatively low position and
acts even when the elevator arrives at
the terminal oor normally.
4C
Err44
Down limit
signal abnormal
Subcode 101: The down
limit switch acts when the
elevator is running in the down
direction.
Subcode 101:
● Check the signal feature (NO, NC) of the
down limit switch.
● Check whether the down limit switch is in
good contact.
● Check whether the limit switch is
installed at a relatively high position and
thus acts even when the elevator arrives
at the terminal oor normally.
4C
Err45
Slow-down
switch
abnormal
● Subcode 101: The down
slow-down distance is
insufcient during shaft
auto-tuning.
● Subcode 102: The up
slow-down distance is
insufcient during shaft
auto-tuning.
● Subcode 103: The slow-
down switch is stuck or
abnormal during normal
running.
Subcodes 101 to 103:
● Check whether the up slow-down switch
and the down slow-down switch are in
good contact.
● Check the signal feature (NO, NC) of the
up slow-down switch and the down slow-
down switch.
● Ensure that the obtained slow-down
distance satises the slow-down
requirement at the elevator speed.

Err46
Re-leveling
abnormal
● Subcode 101: The leveling
signal is inactive during
re-leveling.
● Subcode 102: The re-
leveling running speed
exceeds 0.1 m/s.
● Subcode 103: At startup of
normal-speed running, the
re-leveling state is valid
and there is shorting door
lock circuit feedback..
● Subcode 104: During
re-leveling, no shorting
door lock circuit feedback
or door lock signal is
received 2s after shorting
door lock circuit output.
Subcode 101: Check whether the leveling
signal is normal.
Subcode 102: Check whether the encoder is
used properly.
Subcodes 103, 104:
● Check whether the signal of the leveling
sensor is normal.
● Check the signal feature (NO, NC) of the
feedback contact on the shorting door
lock circuit contactor, and check the relay
and wiring of the SCB-A board.
