Is a simple application to control water level in a tank with two sensors and a pump.
sensor Low = "0" -> Low water level, turn on the pump.
sensor high = "0" -> high water level, turn off the pump.

These are simple commands to turn on the relay

use the Contact = 1

|------] [---------------------------( )--|
turn on relay while contact = 1


|------] [-------------------------( S )--|
set relay if contact = 1


|------] [-------------------------( R )--|
reset relay if contact = 1



use the Contact = 0

|------]/[---------------------------( )--|
turn on relay while contact = 0


|------]/[-------------------------( S )--|
set relay if contact = 0


|------]/[-------------------------( R )--|
reset relay if contact = 0
