Floor Location Fault, FLOOR LOCATION FAULT
Description: Floor magnet location is recorded during the floor height learn procedure. The on and off posi-
tions for both the ULM and DLM sensors are recorded, for a total of four pieces of data for every floor mag-
net, front and rear. The controller watches for the floor magnets constantly and checks to see that each is in
its learned location.
Car Reaction: Run to next stop, then shut down.
Tro ubleshooting:
1. Usually, a magnet has shifted position or fallen off.
2. Check the clearance between the floor sensor board and the magnets. Set if necessary. (Sometimes this
clearance will be off just enough to make some magnets fail to register properly.)
3. Re-learn floor heights.
4. Perform a Terminal synchronization.
Floor Sensor Fault, FLOOR SENSOR FAULT
Description: The system did not detect a floor sensor while performing floor synchronization. Terminal syn-
chronization will be performed as a result.
Car Reaction: Normal stop.
Troubleshooting: Indicates that the elevator location in the hoistway is not where the system expected or the
door zone sensor is not being detected.
1. Fault will be generated if the car was moved while the controller was not powered. The system will detect
movement of the elevator for only ten seconds after power is removed. This will be sufficient to accom-
modate the time required for an elevator to stop after power is removed when running at contract speed.
2. On Inspection, verify that the system is detecting the LU, DZ, and LD signals when the elevator passes a
floor. The signals can be observed on the iView Floor Heights Configuration screen.
Floor Synchronization Fault
Description: While performing floor synchronization, the system either did not receive edge position data
from the cartop or did not detect a floor position magnet where expected.
Car Reaction: The car will stop and initiate terminal synchronization.
Tro ubleshooting:
1. Verify that the car was not moved after power was shut off.
2. Move car past floors in vicinity of the fault and verify the proper activation of the LU and LD sensors.
3. Verify that the system is communicating with the cartop (no Cartop Communication Fault).
4. Verify that the absolute and cartop positions change by the same amount and in the same direction while
moving the car.
5. Verify that a magnet has not fallen off.
6. Check the clearance between the floor sensor board and the magnets. Sometimes this clearance will be
off just enough to make some magnets fail to register properly. Adjust clearance if necessary.
7. Re-learn the floor heights.
8. The iLink, iLand or iBox may be faulty.
Front Auxiliary Door Open Button Bypassed, FRONT AUX DOB BYP
Description: The front auxiliary door open button has been continuously activated for a user-defined time
and is now bypassed according to the user-defined setting. (iView Controller > Configuration > Car Opera-
tion > Doors)
Car Reaction: The front auxiliary door open button is rendered inoperative.
Tro ubleshooting:
1. Check the corresponding input: Front Auxiliary Door - Open Button (Normally low).
2. The operation of the door open button can also be restored by setting the Door open button bypass
option to off (unchecked) (iView Controller > Configuration > Car Operation > Doors).
