Fault
Code
Name Possible Causes Solution Level
Err22
Leveling signal
abnormal
101: The leveling
position deviation is too
large in elevator auto-
running state.
101:
•
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.
•
Check whether the steel rope
slips.
1A
Err24 RTC clock fault
101: The RTC clock
information of the MCB
is abnormal.
101:
•
Replace the clock battery.
•
Replace the MCB.
3B
Err25
Storage data
abnormal
101, 102:
The storage data of the
MCB is abnormal.
101, 102:
Contact the agent or Monarch.
4A
Err26
Earthquake
signal
101: The earthquake
signal is active and the
duration exceeds 2s.
101: Check that the earthquake
signal is consistent with the
parameter setting (NC, NO) of the
MCB.
3B
Err29
Shorting
PMSM stator
feedback
abnormal
101: The shorting
PMSM stator feedback
is abnormal.
101:
•
Check that the state (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
101, 102:
In the normal-speed
running or re-leveling
running mode, the
running time is smaller
than the smaller of F9-
02.
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 floors is too large,
causing too long re-leveling
running time.
•
Check whether signal loss exists
in the encoder circuits.
