Floor Heat Detectors Activated, FLOOR HEAT DETECTORS
Description: One or more floor heat detector inputs are activated. The fire warning light will flash until all
heat detectors have been reset. The fire-warning buzzer will sound until the car is shutdown at a floor.
Car Reaction: A car that is parked at a floor will open its doors and shut down. A car in motion will proceed in
the current direction to the next available floor where the heat detector is not tripped. If all heat detectors in
the current direction are tripped, the car will reverse direction and proceed to the first floor where the heat
detector is not tripped. If again all heat detectors are tripped, the car shall proceed to the main fire recall
floor unless the car is also on Fire Service, in which case the car will proceed to the appropriate fire recall
floor. Once the car is stopped at a floor it shall automatically open its doors and shut down. Then, if the
machine room or hoistway heat detectors are active, a signal is provided to disconnect the main power line
and activate the sprinklers where available.
Floor Heat Detectors Deactivated
Description: All floor heat detector inputs are deactivated.
Car Reaction: The car is allowed to run.
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.
Troubleshooting:
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.
