Please
refer to “Verifying Quadrature Pulse Sequence and Encoder Resolution ” on page 3-10.
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). To learn floor heights, we recommend set-
ting Inspection/High Speed between 50fpm and 125fpm.
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 (Floor Heights from the View > Layouts
menu). Click the Learn tab on the Setup > Floor Heights tab.
5. Select Manual or Auto learn type. (On Manual, 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.
• If Manual learn type was selected, you are prompted to press and hold the iBox
Enable and Up buttons. The elevator will move up the hoistway at Inspection speed.
• You may click Abort at any time to abort the procedure. If the learn process is
aborted, the last saved complete set of values is retained.
8. The procedure is complete when the up normal limit switch (UNTD) is activated (if
Manual learn type, you are prompted to release the Enable and Up buttons) and Done
is lighted.
