BOFA AD Base 1 Oracle Connection

The easiest way to drive this is volt-free from J12 or J13. Otherwise you can use 12V from any of the buttons or J7, but check polarity.

Volt-free input

Item	Qty
#24 wire 2 cond x 330cm (McMaster 9290T31)	1
25mm 3/16” heat shrink	2
white ferrules	2
KK pin	2
KK 2p housing	1
Black zip tie	10

Remove power. Open door using T20 torx driver. (These screws are captive, but difficult to get started when you close it up again.)

Remove knockout on back of machine near power switch. Feed ferrule side of cable though. Follow existing wire path in corner of machine up through the door.

Marked with lines in the photo above, there are two Phoenix blocks on the right side of the circuit board both labeled “RUN”. The one on the 4-pin block ships with a red jumper wire. Remove that jumper wire and screw the ferrule end instead. (Polarity does not matter.)

Remove the board and solder a small piece of wire across the standby switch (SW3), or between the nearby vias from back (above text “STANDBY” and to the right of text “IC8”, marked with circles in the first photo above).

Once length is right, secure wire along with the existing bundle using zip ties. On the outside, this cable has a vertical free run, then snakes under the Epilog behind the rear foot, and through the plate’s ziptie mount.

TODO: Include knockout protector stl with cable clamp.

12V Input

Same as above, but you will additionally need

Item	Qty
KK 3p housing	1
2p Phoenix block	1

Switch to 3-pin KK housing and use on J7 (safest), or 5-pin and use on a button output (probably ok, assuming BOFA board includes protection diode). Install this in the 2-pin RUN, and mind polarity.

Blocked sensor

There are relay outputs that trigger at 75% or fully blocked. These are at the bottom of the board, but we have not experimented with their use.
