DESCRIPTIONS
Bistable Sensors (ETS/NTS) – The Gray Bistable Sensor on the Rail
Encoder Landing system reads the ETS and NTS magnets on the
extension plates. It is latching so it changes state whenever it crosses
over the lifesaver magnets.
Mono-Stable Sensors (DZ) – The Black Monostable Sensor reads the
Door Zone (DZ) magnets on the rails. Some installations require 2 door
zones (DZ1 / DZ2) so two cigar sensors would be used. It is Non-latching
so it only changes state while it is passing over the 6” magnets.
DOOR ZONE MAGNETS
Refer to “UET/DET MAGNET PLACEMENT – BEAM” illustration
The Door Zone magnets are 6” black magnets placed on a steel beam so
that the black “cigar” sensor, mounted on the cartop, can see them when
it passes over.
The door zone magnets are double stacked and aligned along the inside
of the beam.
