Power-off Battery Driven Run Application
During using elevator, if the system power is off, passengers will be shut in car.
HD3L provide battery driven run mode to resolve this problem.

Running Time Sequence
1. When mains power fails, the KM (mains power control contactor) opens, and elevator controller
outputs battery driven run command (BAT), and controls KM1 to close.
2. After some time delay, the elevator controller outputs running command (UP / DN). When HD3L
receives the command, the running contactor will be closed and the brake will be opened. HD3L
accelerates at the line rate of F03.08 (battery driven Acc speed) till the speed of F05.09 (battery driven
run speed).
3. When the elevator runs near a leveling area, the elevator controller cuts off the battery driven run
command (BAT), and HD3L begins to Dec at the rate of F03.09 (battery driven Dec speed) to stop.
4. The controller outputs the brake close signal after the speed decelerates to zero. After some time
delay, controller cuts off the run command (UP / DN) and HD3L releases the contactor. A complete
battery driven running process is finished.
Note:
1. The battery voltage should be bigger than150VDC to ensure normal running.
2. In battery driven running mode, the controller does not detect the Input voltage phase failure.
