Name Possible Causes Solution Level
Err45
Slow-down
switch position
abnormal
101: The down slow-down
distance is insufcient
during shaft auto-tuning.
102: The up slow-down
distance is insufcient
during shaft auto-tuning.
103: The slow-down
position is abnormal during
normal running.
104, 105: The elevator
speed exceeds the
maximum speed when
slow-down is enabled.
101 to 103:
•
Check whether the up slow-
down and the down slow-down
are in good contact.
•
Check the signal feature (NO,
NC) of the up slow-down and
the down slow-down.
104, 105:
Ensure that the obtained slow-
down distance satises the slow-
down requirement at the elevator
speed.

Err46
Re-leveling
abnormal
101: The leveling signal is
inactive during re-leveling.
102: The re-leveling running
speed exceeds 0.1 m/s.
103: At startup of normal-
speed running, the re-
leveling state is valid and
there is shorting door lock
circuit feedback.
104: During re-leveling, no
shorting door lock circuit
feedback or door lock signal
is received 2s after shorting
door lock circuit output.
101: Check whether the leveling
signal is normal.
102: Check whether the encoder
is used properly.
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.

Err47
Shorting door
lock circuit
contactor
abnormal
101: During re-leveling
or pre-open running, the
shorting door lock circuit
contactor outputs for
continuous 2s, but the
feedback is invalid and the
door lock is disconnected.
102: During re-leveling
or pre-open running, the
shorting door lock circuit
contactor has no output,
but the feedback is valid for
continuous 2s.
103: During re-leveling
or pre-open running, the
output time of the shorting
door lock circuit contactor is
larger than 15s.
101, 102:
•
Check the signal feature (NO,
NC) of the feedback contact on
the shorting door lock circuit
contactor.
•
Check whether the shorting
door lock circuit contactor acts
properly.
103:
•
Check whether the leveling
and re-leveling signals are
normal.
•
Check whether the re-leveling
speed is set too low.
