Neo-Natal landing A is S40, landing B is S41, landing C is S50, & landing D is S51.
If think If the sensor is in the car you would just add the NATLH input and be on your way. Car would just hold at the floor if a bracelet was in the car. If they put the sensors in the lobby at floors 2 and 3 you would use NATLA for 2, NATLB for 3, make S40 a 2 and S41 a 3. It would be nice to add NATLI for an indicator in the car to save some future call backs.
Discrete port 12 is Con 37 if we’re talking about a hydro.
