The LED
1
on the sensor board
2
should be on until the elevator lift rod
3
raises to its upper
limit. The sensor LED
1
should then turn off when the elevator lift rod
3
lifts up beyond the
sensor. The output of the sensor board
2
should then transition high (+5V). If the LED
indicators do not illuminate, or the output does not transition high when the elevator rod lifts
beyond the sensor, check the power and connections to the sensor boards. If OK, you may
have a bad sensor.
