To calibrate the floor offsets:
1. Display the Floor Offsets Setup tab by selecting Floor Heights from the View > Layouts
menu and then clicking the Setup > Floor Offsets tab.
2. Move the car to the desired starting landing (e.g. top or bottom terminal landing). The
Ready indicator should light. Follow the instructions provided in the text box.
3. Verify that the machine room INSPECTION switch is in the NORM position. It is recom-
mended to place the car on Independent service while performing this calibration.
4. Click Calibrate to begin making offset measurements. The In progress indicator lights.
5. Run the car to each floor where you want to calibrate the floor offset and perform step
#6. It is not necessary to calibrate all floors each time this procedure is performed.
6. Upon arrival at each floor, wait about 10 seconds to allow the car to settle and for iCon-
trol to acquire the car’s exact position (Acquired light turns on). Measure and record the
distance the car sill is above or below the hoistway landing sill, and record the direction
(car sill above or below). If the sills are not parallel, record the average measurement.
7. Return to the starting floor and measure its offset last. The Done indicator lights indi-
cating that the measurement portion of the offset calibration procedure is completed.
8. Enter the measured value (decimal inches) in the Measured in column (Offsets table on
the Setup> Floor Heights > Floor Offsets tab). If the car sill was above the landing sill,
enter a plus (+) value. If the car sill was below the landing sill, enter a minus (-) value.
9. Click Send to send the new offset values to the iController
