The Smart DC Controller uses LED’s to indicate active inputs when AC power is present. For operators that
use only DC power, you can push a button to show the active inputs. This button is at the bottom left corner
near the EMERG OPEN input.
On a new operator no active inputs should appear until external accessories and wiring are attached. If any
inputs are active before connecting external wiring, refer to Smart DC Controller Troubleshooting.
