Application
The ZEN can be simply used to conserve energy for an escalator with an automatic
operation function. The escalator can be set to operate continuously from 7:00 to 10:00
and 17:00 to 22:00 weekdays and then operate at other times and on weekends only
when people step on the escalator.

timer to operate the escalator for 3 minutes
when pedestrians are detected.
