Learning The Floor Heights; Floor Height Learn Procedure - MCi iControl User Manual

Final Adjustment

Learning the Floor Heights

Learning the building includes determining the location of each floor. iControl does this by
counting pulses sent by the position encoder on the iLand landing system as the elevator travels
the entire length of the hoistway from bottom to top. The iLand position encoder produces 256
pulses per foot of travel.
Note
This is one of the procedures that must be successfully completed before running the elevator
on Test or Normal operation. Before proceeding, be certain you have verified the landing sys-
tem quadrature pulse sequence.

Floor Height Learn Procedure

The speed at which the car learns the hoistway is determined by the Inspection /High Speed
parameter (Configuration > Pattern > Modes tab). For learning the floor heights, we recom-
mend setting Inspection/High Speed between 50fpm and 125fpm. To complete the learn opera-
tion:
1. Place the car on Inspection operation (iBox Inspection switch in the INSP position).
Check the iBox LCD display to verify that it is on Machine Room Insp.
2. On Machine Room Inspection, run the car down until the car is stopped by the normal
limit switch (DNTD). For floor height learning to begin, the ULM signal must be on,
DLM must be off, DNTD must be off, and UNTD must be on.
3. Place the iBox Learn switch in the ON position.
4. In iView, display the Floor Heights Learn layout by selecting Floor Heights from the
View > Layouts menu and then clicking the Learn tab on the Setup > Floor Heights tab.
5. On the Setup > Floor Heights > Learn tab, select Manual or Auto learn type. (On Man-
ual, you run the car through the hoistway using the iBox Enable and Up/Down buttons.
On Auto, iControl will run the car through the hoistway automatically.)
6. If Not Ready is lighted, perform the instructions shown in the message window.
• The Ready indicator lights when the car is placed in Inspection mode (with the
Learn switch ON and the ULM sensor is ON without DLM).
7. When Ready is lighted, click Learn. The In Progress indicator lights when the Learn
button is clicked.
