Appendix III Leveling Switches & Flag Installation

For elevator leveling control, two leveling switches (up/down leveling switches) and some door

zone flags (one in each floor) are required. Two leveling switches are installed on top of car, door

zone flag is installed in hoistway, their dimensions and positions are illustrated in figure below.

Leveling switches can be optical or magnetic.

Door zone flag adjustment:

1. Elevator stop at each floor, measure

car and hall sills difference ΔS on

each level at elevator park (car sills

higher is position, lower is negative).

2. Adjust door zone flag on each floor,

if ΔS>0, flag on this floor should

move down ΔS; move flag up ΔS, if

ΔS<0.

3. Elevator need to redo the hoistway

parameter learning after door zone

flag adjustment.

4. Check elevator leveling on each floor,

and redo part 1-3 if necessary.
