SMART DC CONTROLLER
OVERVIEW OF THE SMART DC CONTROLLER
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"
on page 92.

Amp Draw on Power Supplies
Two power supplies are available:
24VDC and 12VDC
A maximum draw of 1A is available
for each power supply.
NOTE: The 24VDC power supply has
four terminals that can be used in any
combination to draw the available 1A
maximum.
For example:
Amp Draw & Accessories connected to 24VDC
0.50A = Four photo eyes (for entrapment protection)
0.25A = Keypad with light
0.015A = Three HY-5B detectors
