■
When power fails during the Elevtaor operation, the UPS/ARD provide temporary
power supply to the Elevator controller which routes the UPS/ARD power supply to
MD500L inverter also for Elevator rescue operation.
■
When door is fully closed and safeties are connected/closed, the elevator controller
does the rescue function which provides Up/Down direction command and Rescue
speed reference command to the MD500L inverter to run the machine. Elevator
opens/enables the Brake and starts to run in rescue speed set in the inverter (FC-08)
to the rescue oor.
■
If Elevator controller detect the least current direction by running the machine
in both direction for some distance to check the machine drawing current by its
rescue logic or with help of MD500L inverter function (F5-05=36 Software current
exceeding limit), then the rescue direction will be selected in least current direction
by the elevator controller in UPS/ARD rescue mode.
■
Providing Least current direction running in UPS/ARD mode consume lesser
Battery energy.
■
After Elevator reaching Rescue oor, elevator controller withdraws the commands
to the MD500L inverter and stops the elevator by applying the brake on machine
and opens the doors.
