First Time Learn
Apply power to the switch without the actuator present. After the switch
completes the power-sequence (approximately eight seconds), the LED flashes
green eight times, indicating the total number of times a new actuator can be
learned. This LED sequence repeats until an actuator is placed in the sensing
field, or “guard-closed” position, of the switch.

Learning Additional
Replacement Actuators
The switch will automatically start a new learn process when a unique coded
replacement actuator is placed in the sensing field, or “guard-closed” position,
of the switch.

When the switch learns a new actuator, it no longer recognizes previously
learned actuators.
