Final Adjustment
4. Refer to the job prints to determine which Normal Terminal Limit switches (UNTn and
DNTn) are required for this installation and where they should be positioned in the
hoistway. Verify that the Learned position on the Diagnostics > Terminal Switches Sta-
tus tab corresponds to the job prints. If not, refer to the Setup > Terminal Switches tab
and perform the procedure titled "To default terminal switches, please do the follow-
ing:".
5. Move the car to the bottom landing (on Inspection).
6. Place the iBox Inspection switch in the NORM position to allow the car to synchronize to
a floor.
7. Place the iBox Learn switch in the ON position.
8. If the Not Ready indicator is lighted (Setup > Terminal Switches tab), perform any
instructions shown in the message window.
9. When the Ready indicator is lighted, click Learn. The In Progress indicator will light.
10. 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.
11. Place a call to the top terminal landing using the Call Registration panel.
12. When the car stops at the top landing, place a call to the bottom terminal landing.
13. When the procedure is complete, the Done indicator lights and you are prompted to
return the Learn switch to the OFF position. The new NT and ETS switch speeds and
positions are automatically saved to the controller.
14. The learned NT and ETS values are displayed on the Diagnostics > Terminal Switches
Status tab. Verify that all of the switches required for this job have reasonable values dis-
played. If only UNT1 and DNT1 switches are used in addition to UNT5 and DNT5
(always present), the UNT1 and DNT1 values must be 95% of contract speed or less. If
more NT switches are used, UNT1 and DNT1 may have learned speeds equal to contract
speed, but all other NT switches must have learned speeds 95% of contract speed or less.
If some limit switches have learn speeds in excess of their maximum, those switches
must be moved closer to the terminal landings. Alternately, if reduced performance can
be tolerated, the Standard/Deceleration parameter can be reduced.
15. Make several full hatch runs. After each run, on the Diagnostics > Terminal Switches
Status tab, verify that there is a comfortable margin between the last pass speeds and
the Over speed 1 tripping thresholds for the terminal switches used on this job. Also ver-
ify that there is a comfortable margin between the last pass positions and the Upper and
Lower limit position thresholds.
Danger
This procedure must be successfully performed before any passengers are allowed to use the
elevator.
