Door lock fault
● Subcode 101: The door
lock feedback signal
remains active 3s after
door open output.
● Subcode 102: The states
of the door lock multi-way
feedback contacts are
inconsistent 3s after door
open output.
● Subcode 103: Reserved.
● Subcode 104: The higher-
voltage and low-voltage
door lock signals are
inconsistent.
Subcode 101:
● Check whether the door lock circuit is
normal.
● Check whether the feedback contact of
the door lock contactor acts properly.
● Check whether the system receives the
door open limit signal when the door lock
signal is valid.
Subcode 102:
Check whether when the hall door lock signal
and the car door lock signal are detected
separately, the detected states of the hall
door locks and car door lock are inconsistent.
Subcode 104:
● When the higher-voltage and low-voltage
door lock signals are detected at the
same time, the time when the MCB
receives the two signals has a deviation
of above 1.5s. This causes system
protection.
● This subcode is reset at power-off and
power-on again.
