Float switch

With external stairs that are exposed partially or fully to the weather, a heavy rain or meltwater from ice and snow on the steps can lead to water retention in a clogged oil separator.

Heavy duty escalators have a heavy construction, but the control level will be affected after a certain water level in the lower pit.

Because of that we recommend building in a floating switch, turn off the escalator in the preventative 6-7cm water level. We do not recommend installing moist sensors, because they already respond to high humidity and switch off the escalator, without a security risk for the plant or passengers.
