length is not important, but it have to be identic in all floors).
This plate will be evaluated by two inductiv sensors C and D. C is the upper, D the
lower.
Solenoid switch:
Additionally there are in the shaft ceiling and in the shaft pit each 2 bi-stable solenoid-
switches (there could also be roller-switches with repective curves at the cabin). Correction
above and below, as well as inspection-end above and below.
It is important, that the switches are installed as opener. By crossing the above correction- and inspection-
switch they have to be open on the upper side and closed on the lower side. For the lower positioned ones,
the same is valid respectively contrairiwise.
Correction switch
The correction switches serve the deceleration at the termian end stops in case of error (blackout of
incremental encoder) and for learn trip. They are also used for correction of the incremental-encoder-datas.
In the set of drawings, page 50 you can find these respectivly to the speed recommendet distances. The
exact pitch for the braking distance which is choosen by the controller is not important, as this is assigned
by the chossen parameters. However, braking distance and pitch should not have a bigger difference than
45cm.
Inspection end switch
The lower inspection end switch have to be installed in that way, that it opens right before the emergency
limit switch is activated, but after the re-levelling-sensor D lower the precision plate is freed. C is
mentionend in the plate.
For the upper inspection switch it is in the respective way, means IEO will be activated (open contact) if
the sensor C is upper the precision plate and D is still at the plate. Also in this case the emergency limit
switch should be a bit away, that the lift stops before the emergeny limit switch is activated.
The inspection end switches are important for the learn trip.
