Automatic Rescue Device is compatible to all lifts fitted with Induction Motor. Power supply from control panel to motor passes through Automatic Rescue Device. Same safety circuits works both for lift panel as well as ARD.
Whenever power fails in between two floors, the car stops. Then ARD starts its operation in the following sequence:
1. It checks whether lift car is at floor level or not. Floor Level switch is closed when the car is not at floor level.
2. Emergency Light in the car puts on
3. It checks the safety circuit. If car door is closed, it starts moving in one direction and check the load. If load is more and can not rotate the motor, it stops and change the direction of the motor.
4. When it reaches the floor level it stops the car.
5. Start power supply 220 volts AC to the door drive along with the door open signal.
6. After about one minute it switch off the emergency light and put the machine in normal mode. When the power resumes, Batteries get charge with a regulated power supply.
