Description
Fault Cause Analysis
36
Output contactor contact fault
Motherboard has no drive signal on circuit contactor, but input signal is detected at
input testing point (adhesion failure)
Motherboard has drive signal on circuit contactor, but input signal is not detected
at input testing point (non-adhesion failure)
37
Door-lock failure
Door- lock close signal input when the door-open limit signal is in action
When door-lock relay detection is set, the lock input point has inconsistent high
and low voltage detection
38
Brake switch malfunction
Motherboard has no drive signal on brake contactor, but open/close action is
detected at brake switch input testing point (adhesion failure)
Motherboard has drive signal on brake contactor, but no open/close action is
detected at brake switch input testing point
40
Run signal failure
The control part of the AIO sends out run signal, but does not receive the run
signal feedback from the drive part
42
Deceleration switching error
Overtravel in upward movement and the lower level forces slow open/close, or
overtravel in downward movement and the upper level forces slow open/close
45
Pre-opening relay detection
fault
when the pre-opening relay output is detected inconsistent with the pre-opening
for over 0.5s, Y14 has output, but X17 has no input; Y14 has no output but X17has
input
49
Communication failure
Exceptional communications in drive part and control part
50
Parameter error
Parameter read error
54
Inconsistent lock failure
When the door opens, the hall door lock has inconsistent pressure detection point
with the door lock
60
Base closure failure
In operation, the output contactor contact is detected disconnected, turn off the
output of the AIO and report Failure 60
61
Signal start failure
After the brake is opened, no zero servo terminal signal is received returning from
the drive part
62
No speed output
After start, the elevator maintains the speed at 0, and the elevator does not move
67
RTC error
Main board hardware error
68
The combination of the length
of the self study leveling spile
and the distance with the
leveling switch does not meet
the requirements
1) The leveling spile is too long or too short. Algorithm: (length of the leveling
spile + leveling switch space) / 2 less than 100mm or greater than 900mm.
2) The leveling area is too long or too short. Algorithm: (length of the leveling
spile - leveling switch space) / 2 less than 10mm or greater than 100mm
69
The inconsistency of the
number of self study spiles and
the total story number of the
elevator with the level bias
The number of spiles installed = Designed total story number(F11) － Offset
floor (F10). However, the total number of spiles installed is different from the
calculation value.
