10 Leveling Precision Adjustment
Leveling precision adjustment should be performed after comfort level adjustment is satisfied.
10.1 Basic Conditions for Elevator Leveling
1) Make sure the leveling switches and leveling inductor plates are installed in the right
position.
2) Leveling inductor plates’ length on every floor must be same.
3) Leveling inductor plates must be installed vertically.
4) The position of leveling inductor plates should be precise. When elevator is at the leveling
position, the center of the plate and center of two inductors should match together (refer to
appendix III), otherwise elevator leveling will have deflection, which means in up or down running,
elevator stops higher or lower than leveling position.
5) If magnetic inductors are adopted, please make sure the inductor plates inserting to the
inductor sufficiently, otherwise it will influence the reaction time of inductor, in that way elevator
will overruns the leveling position.
6) To ensure precise leveling, system require elevator to crawl for a certain distance before
stop.
7) In practice, first make adjustment for a middle floor, until leveling is precise. Then, adjust the
other floors on the base of these parameters.
After adjusting curve selection, ratio and integral gain in the above context, please make sure
every time elevator runs up or down, when stop at middle floor, its leveling positions are the same
(or deflection ≤±2~3mm every time).
10.2 Leveling Parameter Adjustment
If elevator still cannot achieve desired leveling condition with adjustment based on instructions
in section 1 of this chapter, further adjustments can be done by parameters. After elevator stops in
normal running, if running speed curve has no problem (for example, no sudden stop or overrun
beyond leveling zone), if elevator overruns the leveling position (it stops higher in up-running, lower
in down-running), please decrease leveling adjustment parameter F1-17（default: 50）. if elevator
cannot reach the leveling position (it stops lower in up running, higher in down running), increase
leveling adjustment parameter F1-17, generally the range of this parameter is 40~60, if the
adjustment is too big, please adjust driving parameter PI, or the shape of speed curve (F1-10~F1-15).
Warning: If the leveling precision of a majority of floors are no good, you should firstly adjust
leveling parameter to make most of them leveled, and then adjust the flag of specific ones.
