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 SHOW LEDS 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 Troubleshooting.
