Up Normal Terminal Switch 'n' Position Fault, UP NTS'n' POSITION FLT (n = 1 to 6)
Description: When the switch opened or closed, the car's reported position was different from the learned
position by a value exceeding the margin set on the Configuration > Terminal Switches tab. This may mean
that the switch opened early, late or not at all on approach to the terminal. It may also mean that the switch
closed early, late, or not at all on departure from the terminal. Finally, the switch can go open while standing
at a floor where its learned position is closed, or go closed at a floor where its learned position is open. This
fault may be bypassed on the Diagnostics > Fault Bypass tab.
Car Reaction: If traveling up, the car executes an emergency slowdown, then continue at low speed until it
encounters a floor. The car stops at the floor, opens its doors, and performs a floor sync operation. If the
fault persists, the car goes out of service. If traveling down, the car continues normally to the first stop,
opens its doors and performs a floor sync operation. If the fault persists, the car goes out of service. If
stopped at a floor, the car opens its doors, does a floor sync, and, if the fault persists, goes out of service.
Troubleshooting:
1. On the Diagnostics > Terminal Switches Status tab, compare the Last pass position to the Learned posi-
tion for this switch.
2. If the fault is mechanical (switch movement, magnet movement, or bad traveler cable), the fault will
tend to repeat at the same position every time.
3. A stuck switch is easy to spot by running the car on inspection and observing the input LEDs on the iBox.
4. Perform a Terminal Sync operation (Terminal button on the Configuration > Pattern > Common tab).
