Troubleshooting
Terminal Synchronization Fault, TERMINAL SYNC FAULT
Description: System did not receive edge position data from cartop or did not detect a floor position magnet
where expected.
Car Reaction: Car stops after crossing floor magnet at top or bottom terminal and is not allowed to move.
Troubleshooting:
1. Verify car was not moved after power shut off.
2. Verify up/down normal terminal switch #5 opens at correct location. When up/down switch opens, no LU
or LD sensor should be active. Also, only one floor magnet should be encountered in direction of travel
after up/down switch opens.
3. Move car past floors around vicinity of fault and verify proper activation of LU and LD sensors.
4. Verify system is communicating with cartop (no Cartop Communication Fault).
5. Verify absolute and cartop positions change by same amount and same direction while moving car.
6. Verify terminal magnet has not fallen off.
7. Check clearance between floor sensor board and magnets. Sometimes clearance will be off enough to
make some magnets fail to register. Adjust clearance if necessary.
8. Re-learn the floor heights. The iLink, iLand or iBox may be faulty.
Test Mode, Test
Description: Elevator in the Test mode. iBox Test switch in Test position.
Car Reaction: Door operation is disabled. This setting is used to adjust or test the elevator.
This Car Alternate Fire Sensor Recall, THIS CAR ALT FIRE
Description: Recall to alternate fire floor due to active or latched smoke detector input(s) from cars hoistway
or machine room.
Car Reaction: Car proceeds to user-defined alternate fire recall floor. At recall floor, door operation per user-
defined door operation under fire recall operation. The fire warning indicator light will flash.
Troubleshooting:
1. If in error, inspect sensors, inputs, and connections.
2. Related Inputs: This Car Alt Recall sensor inputs as shown on the job prints.
This Car Main Fire Sensor Recall, THIS CAR MAIN FIRE
Description: Recall to main fire floor for active/latched smoke detector input from hoistway or machine room.
Car Reaction: Car proceeds to user-defined main fire recall floor. Once at recall floor, door operation per user-
defined door operation under fire recall operation. The fire warning indicator light will flash.
Troubleshooting:
1. If in error, inspect the sensors, inputs, and connections.
2. Related Inputs: This Car Main Recall sensor inputs as shown on the job prints.
Unintended Motion Fault (see Safety A Unintended Motion Fault)
Up Direction Limit Open, UP DIR LIMIT OPEN
Description: Up normal terminal direction switch open
Car Reaction: Immediate stop if moving. Further up direction movement prevented.
Troubleshooting:
1. Verify switch operating properly.
2. Verify correct state of iBox UNTD input.
3. Verify UNTD switch activating/deactivating at appropriate location (normally 2” below bottom terminal
landing - see prints).
