Troubleshooting
Emergency Power Recall (In Service), EP RECALL-IN SERVICE
Description: Event is logged and related car status messages displayed on OBD and iView if a car that has
been commanded to recall during emergency power remains in service for car calls.
Car Reaction: An attendant operated car (FIRE II, IND, ATA, CFSS In-Car, EMS) goes back into service for car
calls only when it is selected to recall. The car is shut down once it is at a floor with doors open or if the car
fails to move or open its doors within a user defined timer (30 seconds).
Troubleshooting: Check the Emergency Power Version option (System > Configuration > Emergency Power)
and set it to Pre 2008 if this operation is not desired.
Emergency Power Run, EMERG POWER RUN . See Emergency Power Activated.
Description: This elevator is allowed to respond to calls during emergency power operation.
Troubleshooting:
1. Related inputs (only on elevators with emergency power overlay operation)
EPR: Normally low (low to run the car), PTR: Normally low (low to run the car)
Emergency Power Shutdown, EMERG POWER SHUTDOWN . See Emergency Power Activated.
Description: This event is logged when emergency power is initially activated or if communication with the
emergency power supervisor has been lost while on emergency power.
Car Reaction: Emergency stop. Car removed from service.
Troubleshooting:
1. Related inputs:
EPI: Active level field adjustable.
Emergency Stop Input Activated, EMERGENCY STOP INPUT
Description: Events logged and related status messages displayed to reflect status of Emergency Stop Input.
Car Reaction: When Emergency Stop Input activated, car makes an emergency stop and cancels all calls.
This input has priority over all modes of operation including Fire Service.
Troubleshooting: Check the status of the Emergency Stop Input.
Emergency Stop Input Deactivated see Emergency Stop Input Activated.
ESTOP due to disabled direction of travel
Description: The car has performed an emergency stop because the current travel direction has been disal-
lowed due to flood operation becoming active, disallowing the destination floor.
Car Reaction: After stopping, the car will correct to a floor above the flood zone.
ETA Mode Activated
Description: The Estimated Time of Arrival dispatching engine is now active.
Excessive Brake Feedback Fault, EXCESS BRAKE FDBK FLT
Description: After brake activity, controller checks to see that current is bleeding off properly. (After 1 sec-
ond, voltage should be at or below 85% of voltage applied by last command.) Fault issued if brake voltage
too high when checked.
Car Reaction: Emergency stop: Motor contactor and brake contactor immediately dropped.
Troubleshooting:
1. At factory, RB (brake resistor value) set 3 to 5 times brake coil resistance. Reduce RB to allow current to
bleed off more quickly. (Do not reduce RB below 3 times brake coil resistance.) Please refer to “Verifying
Brake Current Resistance” on page 2-9 .
2. On iView Brake screen, Timers tab, reduce Voltage Decay Time (minimum, 0.0 seconds).
3. Check Brake Voltage Feedback test point on iView Oscilloscope screen.
4. Check iField Brake Module connections.
5. Check brake and brake connections.
6. If you continue to see this fault, you may have a defective brake module or iBox Safety board.
