Control System

Control System

JS & Son traffic control system is based on advanced micro controller system incorporating field proven and field programmable sophisticated software to ensure efficient and reliable services under demanding traffic condition. There are different control system to meet the diverse need of different type of requirement.

The system can be programmed for single speed, Two speed of Variable Frequency Drive (VFD) with either manual or auto door operation available for all type of applications. Error message display in LED/Dot matrix /7 Segment modes included for quick fault diagnosis easy and speedy debugging of controller.

Geared Elevator Drive Machine

Geared Elevator Drive Machine

The Machine will be traction type with an AC motor, electro mechanical break, heat treated alloy steel worm Shaft, centrifugally cast bronze worm genar wheel & superior grade cast iron drive sheave all compactly mounted on a single base or bed plate. Taper Roller Bearings ensure enough traction and minimize rope wear and tear.

Gearless Elevator Drive Machine

Gearless Elevator Drive Machine

Gearless motor, the latest innovation in elevator technology based on permanent magnet synchronous gearless machine is in great demand in the elevator industry because of the following technical advantages.

The PMSM (Permanent Magnet Synchronous Motor) uses a rare earth permanent magnet with high magnetic flux density. In this system as a permanent magnetic flux is established, there is no need to release magnetizing current which in turn result in efficient control and energy saving. This invention allows the motor to have short length with large diameter and therefore a high torque. As such it does not requires gears and is compact in size and weight which allow installation in a small space. It is less noisy and provides unsurpassed smoothness and ride quality. 

JSS ARD System

JSS ARD System

Auto Rescue Device (ARD) is an advanced rescue system for rescuing passengers from an elevator in event of a power failure. Manual rescuing is time consuming and prome to heightened anxiety among the passenger.

Attempt to manually rescue may also result in injuries if done by untrained persons. ARD provides required power to move the elevator car to the nearest landing and open the door automatically to rescue the passenger.

Salient Features

  • Obstacle detection by drive technology.
Infra Red Full Length Door Detector

Infra Red Full Length Door Detector

The door detector projects a curtain of 80 criss cross (zig zag) and direct beams to detect person or object in the path of the closing door, reverse the opening process on detecting obstruction, restarts closing after the pre-set time lag for open door state.

Salient features:

  • Highly reliable operation and easy to install
  • Unaffected by alignment and door movement
  • Insensitive to dust. Sophisticated software control. On-board diagnostics
  • Fail Safe electronics.
