Recommended distances between leveling and stop switches

With no load in the car, the deceleration time should be 2 to 2,5 secs. from full speed to leveling speed.
The leveling time should be 1 to 2 secs.
Accurate landing can be affected by different factors as follows:
a. If the leveling speed is fast i.e. 0,1 m/sec (20 ft/min), landing will not be as accurate as when the leveling
speed is slower i.e. 0,05 m/sec (10 ft/min).
b. If the soft stop adjustment ‘5’ is set too soft, stopping will be less accurate as when ‘5’ is set for a quicker
stop.
c. Particularly when the mechanic can not see the operation of the elevator car, it is possible that the elevator
has not finished decelerating from fast speed before reaching the floor. In other words, the elevator has not
slowed down to its correct leveling speed before the stop switch is actuated.
Usually, the leveling operation can be observed through the crack in the car doors. Alternatively, in the
machine room, the turbulant noise within the valve during leveling can be heard and should last 1 to 2
secs. following 2 to 2,5 secs. deceleration time with no load in the car.
d. A difference in landing accuracy between the elevator being loaded and unloaded, can be due to the car
under load, leaning to one side by several millimeters causing an alteration in the operating position of the
stop switch by some centimetres.
