Error
Code
Definition
Possible Solution
Er25
Heat sensor protection: Braking resistor or
motor is over heat (X32 invalid).
Check heat sensor circuit. If this error cannot reset in
90s, Y23 relay on controller will output KMC contactor
open signal.
Er26
Door inter-Lock fault: Door inter-Lock contactor
working state does not match to its coil (X11,
X36 input different)
Check door interlock contactor terminal & coil and
their related terminal on controller.
Er27
Emergency stop fault: Emergency stop
contactor working state does not match its coil
state. (X13, X29 input different)
Check emergency stop contactor terminal & coil and
their related terminal on controller.
Er28
Top/bottom terminal (1st or 2nd) adhesions.
(X16 or X17 valid when elevator outside their
floor)
Terminal invalid in corresponding floor. Check terminal
signals.
Er29
Communication interference too much (In
system or in duplex communication).
Check system ground condition; Eliminate
interference.
Check COP/LOP for possible damage that may
influence CAN BUS communication.
Er30
Door open fault (car cannot open door)
1. Run elevator in inspection mode, give door open
command and check Y2 for output signal;
2. If Y2 has no output, need to check door open, close
limit switch and related signal;
3. Be aware whether front door and rear door setting
is opposite when two door mode is used.
Er31
Door close fault (car cannot close door)
Normally due to door not installed properly and short
circuit door interlock circuit. Check if door close and
door interlock circuit are output at same time.
Er32
Floor number counting error.
A sudden power break may affect terminal/limit
switches and cause floor number error. Elevator will
then return to bottom floor for recalibration.
Er34
External switching power supply 24V sag fault
1. Check External switching power supply 24V
connection;
2. Fault prompt given if detect the external voltage is
lower than 16V.
Er35
Master clock error
Main board hardware circuit working abnormal. Please
contact supplier.
Er36
Internal power supply 5V error
Fault prompt given if detect the 5V voltage is lower
than 4.7V.
Er37
Running contactor shakes in brake open action.
Check running contactor action and X5 running
contactor feedback.
Er39
Brake force test failure, lack of brake force.
Examine the brake. Powering off can make it recover,
however it should do a brake force test again to ensure
enough brake force.
Er40
Brake is invalid and cause sliding error.
The safety protection function of safety circuit board
has acted, the car has creeped and released people
after finding brake invalid. Then the car return to top
floor and try to brake again, but the brake is still invalid
and the car slide. System latch the error unless power
off.
Er41
Unexpected slide error examines brake force.
The safety protection function of safety circuit board
has acted, the brake is successfully closed while car's
creeping. System records the slide in fault record as a
warning of brake force fault but shows no error.
Er42
While emergency running input is valid, the car
moves unexpectedly because of the
invalidation of brake force.
The car slide, the system report error and save fault
record to avoid other unpredictable dangers. Because
the voltage of emergency power may be too low while
creeping.
