Pre-start Door Lock Fault
Description: Once the decision to move the elevator has been made, three acknowledgments (motion start,
door lock and drive start) must be received before physical movement is allowed. However, if the system is
so configured, pre-start sequencing will begin while the doors are closing. If the door lock acknowledgement
is not received within 15 seconds (after the pre-start sequence is begun), this fault is generated.
Car Reaction: The pre-start sequence will stop and the sequence will repeat. If the fault persists, an exces-
sive restarts fault will occur.
Troubleshooting:
1. Verify that the doors (front and/or rear) become locked within the prescribed time.
2. Verify, via the iView Diagnostics - Motion tab, that the system sees the doors closing and becoming
locked within the prescribed time. The information reflects front and rear door status combined.
3. Verify, via the Diagnostics - Car Operation - Front/Rear tabs, that the system sees the front/rear doors
closing and becoming locked within the prescribed time.

Description: One or more rear door failures to close have been detected. The controller will attempt to close
the doors as defined by user parameters (door close protection timer and number of attempts) before
declaring this fault. iView Car Operation/Doors tab.

vice (hall calls assigned to this car are canceled or reassigned to other cars if available). Doors may be closed
using constant pressure on the rear door close button.
Troubleshooting:
1. Door closed status is determined by the rear door close limit and by the rear door position monitor con-
tact if applicable.
2. Check the wiring of these signals.
3. Check the door close protection timer and number of closing attempts on the Operation/Doors tab.
