OTHER SPECIFICATIONS OF THE PASSENGER LIFT:

A.C. VARIABLE VOLTAGE VARIABLE FREQUENCY CONTROL 1. MACHINE:

The machine shall be of the single wrap traction type, and shall include a motor, Electro-Mechanical brake, chromium molybdenum steel worm, bronze gear, chromium molybdenum steel sheave all compactly mounted on a single base of bedplate. The worm shaft shall be provided with taper roller bearings to take the end thrust and self-aligning spherical roller bearing shall furnish for the sheave shaft to ensure alignment and long bearing life. The driving sheave shall be grooved to ensure sufficient traction and minimize rope wear. Adequate means of lubrication shall be provided for all bearings and the worm gear.

2. BRAKE: The direct current brake shall be spring applied and electrically released and designed to provide smooth stop under variable loads.

3. MOTOR: The A.C. Motor designed for elevator service, shall have high starting torque with low starting current.

4. Microprocessor Based Control shall have an operational card file containing a logic board with a Microprocessor chip, Random Access memory (R.A.M.) and Erasable Programmable Read only Memory (E.P.R.O.M.) chips to monitor and take over the commands of the elevator.

The Motion control shall consist of high performance, fully digital control Variable Frequency drive which directly controls the torque and speed of the Elevator Motor and thus provides constant speed control under all load conditions. The Microprocessor based controller shall contain various user friendly features such as:

Detection of stuck hall button. Motor Over current protection (Built in inverter drive). Fast speed / deceleration protection. Passenger Overload Warning Device.

The system shall continuously monitor critical aspects of system health. Self health diagnostic capabilities shall be built into the control system to speed up trouble-shooting so that the same could be monitored from seven segment display provided in the logic board. This shall facilitate quick identification of fault and restoration to normal operation.

5. ACVVVF (VARIABLE VOLTAGE VARIABLE FREQUENCY DRIVE) The AC Variable Voltage Variable Frequency Drive shall possess the following benefits:

Smooth & Controlled Acceleration / Deceleration. Better Riding Quality. Assured Levelling Accuracy of + 5%.

Improved Flight Time. Improved Reliability & Increased Efficiency. Reduced Power Consumption - about 50% and improved Power Factor. Reduced Heat Release. Flexibility of Programme & Programming of Features at Site. Simplified Maintenance.
