Terminals 8 and 9 are the Switch Green sensor. This will turn ON the accessory.
Terminals 3,4 and 5, 6 attach to the AC or DC input power source.
Program a time delay as desired. It is also possible to use the
Switch RED or Alternate sensor to turn off the accessory instead of using a time delay.
When sensor GREEN is sensed the YardMaster will switch power to the
SWITCH GREEN relay terminals and turn on the accessory. After the timer has expired
(or the RED sensor is triggered) the YardMaster will return to the Switch RED state and turn
off the signal light.
Whatever power is applied to terminals 3 and 4 will be switched to terminals
19 and 20 when the YardMaster is GREEN.
Notice that if a Switch RED sensor used instead of a programmed time delay
the train can turn ON the accessory with the RED sensor and then turn OFF the
accessory with the GREEN sensor.
