Description
Fault Cause Analysis
In upward operation, the upper limit disconnected
In upward operation, the elevator crosses the top level
04
Elevator overtravels when
going downwards
In automatic operation, the upper and lower limit switches are in action at the same
time and the elevator is not at the lowest level
In downward operation, the lower limit disconnected
In downward operation, the elevator crosses the bottom level
05
Door lock will not open
Door fails to open in position after the door-open signal outputs for consecutive 15
seconds (except the absence of door-lock signal), reports failure for 3 times
Short circuit for lobby door lock: the elevator is in the hall area. Lobby door lock
signal exists without car door lock and with door-open limit signal (for consecutive
1.5 seconds) (only effective for car door separation under high-voltage input)
06
Door lock will not close
Door fails to close in position after the door-close signal outputs for consecutive
15 seconds (except the existence of door-lock signal) and reports failure for 8
times
Inconsistence for 4 seconds between door-close limit and door lock determines
time-out for door close (except the existence of door-lock signal). Failure reported
after 8 inconsistencies
08
CANBUS communication
failure
Communications interference
Terminal resistance is not under short circuit
Breakdown in communications
Failure reported after disconnection with lift car panel SM-02 communication for 4
seconds.

Dislocation of
upward deceleration switch 1
Check after self study or with power on: the position of the upward deceleration
switch on the single level is 3/5 higher than the story height of the top floor
Check after self study or with power on: the position of the upward deceleration
switch on the single level is shorter than the minimum deceleration distance
Check the operation: the position of the upward deceleration switch on the single
level is 100mm lower than the position of the upward deceleration switch on the
single level in the well learning
Check the operation: the position of the upward deceleration switch on the single
level is 150mm higher than the position of the upward deceleration switch on the
single level in the well learning
Check at stop: the position of the upward deceleration switch on the single level is
100mm lower than the position of the upward deceleration switch on the single
level in the well learning
Check at stop: the position of the upward deceleration switch on the single level is
150mm higher than the position of the upward deceleration switch on the single
level in the well learning, and the deceleration switch on the single level is not in
action
In automatic operation, the upper and lower limit switches are in action at the same
time and the elevator is not at the highest level
11
Dislocation of
downward deceleration switch 1
Check after self study or with power on: the position of the downward deceleration
switch on the single level is 3/5 higher than the story height of the bottom floor
Check after self study or with power on: the position of the downward deceleration
switch on the single level is shorter than the minimum deceleration distance
Check the operation: the position of the downward deceleration switch on the
single level is 100mm higher than the position of the downward deceleration
