Backup Power Direction Reversal
Description: The Backup power recall reverse direction input has been activated (signal from the TAPS Trac-
tion Auxiliary Power Supply).
Car Reaction: The car direction of travel is reversed unless the car is on Earthquake operation and the CW1/
CW2 inputs (Counterweight movement sensor) are active and reversal would move the car in the direction
towards the counter weight.
Backup Power Recall OFF
Description: The Backup power recall input has been deactivated.
Backup Power Recall ON, BACKUP POWER RECALL
Description: The Backup power recall input has been activated (signal from the TAPS Traction Auxiliary
Power Supply).
Car Reaction: If the car is not currently at a floor, it will move to a floor and cycle the doors. If no load
weigher is used, the car will move to the closest floor. If a load weigher is used, direction is dependent on the
car load and the Counterweight percentage parameter. If load weight is greater than Counterweight percent-
age, car moves down and vice versa.
Backup Power Unit Failure Activated, Backup power unit failure, BACKUP POWER FAILURE
Description: The Backup power unit failure input is low.
Car Reaction: None. The event is displayed and logged.
Troubleshooting:
1. Check the UPS unit for faults.
2. Check the connection to the Backup power unit failure input.
3. It may be necessary to replace the battery
Backup Power Unit Failure Deactivated
Description: The Backup power unit failure input has changed back to its normally high state.
Balanced Mode
Description: Passenger operation. Up and Down traffic treated equally. Assigned by group controller.
Battery Voltage Low-IMP, BATTERY VLTG LOW-IMP
Description: The voltage on Battery B1 on the IMP board has dropped below 2.22 VDC and the battery must
be replaced. Otherwise the BBRAM will be unable to retain the data stored during a power loss or shut down.
Blocking New Remote Connections, BLOCKING REMOTE UIS
Description: When a car switches from Local to Local Dispatcher, many parameters and connections to other
cars must be stabilized. During this time the new Local Dispatcher will not accept any new remote connec-
tions for 30 seconds.
Car Reaction: iView will remain connected if it was already connected. Any new iMonitor, iReport, Liftnet,
BMS, etc. connections will be denied for 30 seconds while the car is syncing up and stabilizing data.
Troubleshooting:
1. If this message is persistent for more than 30 seconds or if it seems to come and go for extended periods
of time, the car may be confused as to if it should be the Local Dispatcher. Check the Alternate Dis-
patcher settings (System Configuration > Building tab), and Car ID (Controller > General > General tab)
parameters. This has been an issue when upgrading a car designated as Alternate Dispatcher with a Car
ID not = 1. A reboot was necessary to fix it, but is also necessary after an upgrade anyway.
Brake Contactor Driver Proofing Fault, BRAKE CNT DRV PRF FLT
Description: Fault signal for brake contactor driver proofing.
Car Reaction: None
Troubleshooting:
1. Verify brake contactor driver proofing circuits.
