Fault
Code
Name Possible Causes Solution
Level
Err22
Leveling signal
abnormal
● Subcode 101: The leveling
signal is stuck.
● Subcode 102: The leveling
signal is lost.
● Subcode 103: The leveling
position deviation is too
large in elevator auto-
running state.
Subcodes 101, 102:
● Check whether the leveling and door
zone sensors work properly.
● Check the installation verticality and
depth of the leveling plates.
● Check the leveling signal input points of
the MCB.
Subcode 103:
Check whether the steel rope slips.
1A
Err23
Motor short
circuit to
ground
Short circuit to ground exists
on the motor side.
Check whether short circuit to ground exists
on the motor side.
5A
Err24 RTC clock fault
Subcode 101: The RTC clock
information of the MCB is
abnormal.
Subcode 101:
● Replace the clock battery.
● Replace the MCB.
3B
Err25
Storage data
abnormal
Subcodes 101, 102:
The storage data of the MCB
is abnormal.
Subcodes 101, 102:
Contact us or directly our agent.
4A
Err26
Earthquake
signal
Subcode 101: The earthquake
signal is active and the
duration exceeds 2s.
Subcode 101: Check that the earthquake
signal is consistent with the parameter
setting (NC, NO) of the MCB.
3B
Err29
Shorting PMSM
stator contactor
feedback
abnormal
Subcode 101: Feedback of
the shorting PMSM stator
contactor is abnormal.
Subcode 101:
● Check that the signal feature (NO, NC)
of the feedback contact on the contactor
is correct.
● Check that the contactor and
corresponding feedback contact act
correctly.
● Check the coil circuit of the shorting
PMSM stator contactor.
5A
Err30
Elevator
position
abnormal
Subcodes 101, 102:
In the normal-speed running
or re-leveling running mode,
the running time is larger than
the smaller of F9-02 and (FA-
38 + 10), but the leveling
signal has no change.
Subcodes 101, 102:
● Check whether the leveling signal cables
are connected reliably and whether
the signal copper wires may touch the
ground or be short circuited with other
signal cables.
● Check whether the distance between two
oors is too large or the re-leveling time
set in F3-21 is too short, causing over
long re-leveling running time.
● Check whether signal loss exists in the
encoder circuits.
