Power Up Position Synchronization Required at Terminal
Description: Position synchronization at terminal landing required after power-up/reset. Terminal synchroni-
zation after power-up will occur if the elevator was required to synchronize before power was lost or the con-
troller was reset, or if synchronization information in battery backed SRAM is invalid.
Car Reaction: The elevator will synchronize at a terminal landing.
Tro ubleshooting:
1. Battery may need to be changed.
2. Check for faulty SRAM.
3. Check for SRAM not correctly inserted in socket.
4. Check for faulty iBox.
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.
Tro ubleshooting:
1. Verify that the doors (front and/or rear) become locked within the prescribed time.
2. Verify, iView Diagnostics - Motion tab, that system sees doors closing and locked within 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.
