Description
Fault Cause Analysis
21
Motor overheating
Input signal at motor overheating point
22
Motor reverse failure
Skid for consecutive 0.5 seconds (upward speed feedback<-150mm,
downward speed feedback>150mm)
23
Elevator overspeed failure
Failure 23 reported when speed feedback value is greater than allowable speed for
0.1 seconds
When the given speed is less than 1m / s, allowable speed= given speed +0.25 m /
s
When the given speed is greater than 1m / s, allowable speed= given speed *1.25
Maximum allowable speed < rated speed * 108%
When terminal level runs at a decelerating speed of 0.8m/s
2
, Failure 23 reported
when speed feedback value is greater than allowable speed for 0.1 seconds
24
Elevator over-low speed
Failure 24 reported when speed feedback value is less than allowable speed for 0.5
seconds
When the given speed is less than 0.5m / s, allowable speed= given speed -0.25 m /
s
When the given speed is greater than 0.5m / s, allowable speed= given speed *0.5
27
Sensor failure for upper
leveling floor
After high-speed operation stops, the sensor for upper leveling floor is not
in action.
Failure 27 reported, when the action on the sensor for upper leveling floor is
greater than the maximum effective protection distance or greater than the
maximum invalid protection distance
When the length of the leveling spile is less than 300mm: maximum protection
distance for effective action = 300mm*4
When the length of the leveling spile is greater than 300mm: maximum protection
distance for effective action = length of the leveling spile*4
When the top floor is less than 3: maximum protection for invalid action
= maximum story height*1.5
When the top floor is greater than 3: maximum protection for invalid action
= maximum story height*2.5
28
Sensor failure for lower
leveling floor
The sensor for lower leveling floor is not in action
Failure 28 reported, when the action on the sensor for lower leveling floor is
greater than the maximum effective protection distance or greater than the
maximum invalid protection distance
When the length of the leveling spile is less than 300mm: maximum protection
distance for effective action = 300mm*4
When the length of the leveling spile is greater than 300mm: maximum protection
distance for effective action = length of the leveling spile*4
When the top floor is less than 3: maximum protection for invalid action
= maximum story height*1.5
When the top floor is greater than 3: maximum protection for invalid action
= maximum story height*2.5
30
Leveling position error is too
large
Test the leveling position error at stop. Failure report when the error detected is
greater than the value set by F146.
32
Safety loop disconnected in
operation
Safety loop disconnected in operation
35
Brake contactor contact fault
Motherboard has no drive signal on brake contactor, but input signal is detected at
input testing point (adhesion failure)
Motherboard has drive signal on brake contactor, but input signal is not detected at
input testing point (non-adhesion failure)
