Position Synchronization Fault
Description: The system was not able to read the position correction value stored in battery backed RAM
when the controller powered up. This fault usually results in a floor sensor fault or a position location fault.
Car Reaction: None.
Troubleshooting:
1. Verify iBox battery connection and charge (lower left side of ICE-IMP board - iBox cover removed).
Battery type: 1/2 AA, 3.6V Lithium. Manufacturer: SAFT, part # LS14250. MCE part # 30-05-0001.
Position Synchronization Required at Floor, POSITION SYNC-FLOOR
Description: The elevator needs to verify position by crossing a door zone sensor.
Car Reaction: Cancel all existing calls, synchronize to floor.
Position Synchronization Required at Terminal, POSITION SYNC-TERMINAL
Description: The elevator does not know where it is. It needs to locate a terminal door zone sensor to estab-
lish position.
Car Reaction: Cancel all existing calls, synchronize to terminal.
Position Synchronized at Floor
Description: The elevator has completed synchronizing its position using a door zone sensor. See Position
Synchronization Required at Floor.
Car Reaction: Return to normal service.
Position Synchronized at Terminal
Description: The elevator has completed synchronizing its position using a terminal door zone sensor. See
Position Synchronization Required at Terminal.
Car Reaction: Return to normal operation.
Power Transfer Input Activated, Power Transfer, POWER TRANSFER
Description: Power transfer input activated. Power is being transferred from the emergency generator to
commercial service.
Car Reaction: Cancel existing calls. Stop at next floor and open doors.
Troubleshooting: Check the Power Transfer input.
Power Transfer Input Deactivated
Power Up Position Synchronization Required at Terminal
Description: Position synchronization at a terminal landing required after power-up/reset. Terminal synchro-
nization after power-up will occur if the elevator was required to synchronize before power was lost or the
controller was reset, or if synchronization information in battery backed SRAM is invalid.
Car Reaction: The elevator will synchronize at a terminal landing.
Troubleshooting:
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.
