Table 8-2 Fault levels
Category Action Remarks
Level 1
1. Display the fault code.
2. Output the fault relay action
command.
1A. The elevator running is not affected on any
condition.
Level 2
1. Display fault code.
2. Output the fault relay action
command.
3. Continue normal running of
the elevator.
2A. The paralle/group control l function is
disabled.
2B. The door pre-open/re-leveling function is
disabled.
Level 3
1. Display the fault code.
2. Output the fault relay action
command.
3. Stop output and apply the
brake immediately after stop.
3A. In low-speed running, the elevator stops at
special deceleration rate, and cannot restart.
3B. In low-speed running, the elevator does
not stop. In normal-speed running, the elevator
stops, and then can start running at low speed
after a delay of 3s.
Level 4
1. Display the fault code.
2. Output the fault relay action
command.
3. In distance control, the
elevator decelerates to stop
and cannot run again.
4A. In low-speed running, the elevator stops
under special deceleration rate, and cannot
restart.
4B. In low-speed running, the elevator does
not stop. In normal-speed running, the elevator
stops, and then can start running at low speed
after a delay of 3s.
4C. In low-speed running, the elevator does
not stop. In normal-speed running, the elevator
stops, and then can start running at low speed
after a delay of 3s.
Level 5
1. Display the fault code.
2. Output the fault relay action
command.
3. The elevator stops
immediately.
5A. In low-speed running, the elevator stops
immediately and cannot restart.
5B. In low-speed running, the elevator does
not stop. In normal-speed running, the elevator
stops, and then can start running at low speed
after a delay of 3s.
•
A, B, and C are fault sub-category.
•
Low-speed running involves inspection, emergency evacuation, shaft auto-tuning, re-leveling,
motor auto-tuning, base oor detection, and running in operation panel control.
•
Normal-speed running involves automatic running, returning to base oor in re emergency
state, reghter operation, attendant operation, elevator lock, and elevator parking.
