We have successfully integrated the photoelectric sensors to the escalator start / stop signals.
Some will call it energy saving escalator as it will not run the motor when there is no passenger.
The sensors detect the passengers and swtich ON automatically to activate the escalator and employ a delayed switched OFF when nobody is using the escalator.
This is a very good addition for energy saving purpose.
Why should this system be implemented to escalator?
- extend escalator lifespan by shortening the operation time.
- save man-power as escalator will be started/turned on by sensor.
- save energy = save money
