Change out the AF Cards (if present)

If your rack supports Advanced Features (AF)

you will need to replace the AF cards as well.

CEM3 only supports use of the newer-style AF

cards, which have eight address switches and

two LEDs (shown at right).

AF cards are located on the right side of the

dimmer module slot between the copper neutral

busses and the dimming circuitry cards.

To replace the AF cards:

Step 1:

Remove the old AF cards by flipping

the white retainer tab on the cards into

the down position.

Step 2:

Pull the old cards out of the slots.

Step 3:

Set the DIP switches on the new cards according to the chart below. Only the first

two DIP switches are used.

Step 4:

Slide the new AF cards completely into the vacant slots starting with card #1 in

the top. The number of cards depends on rack size.

Step 5:

Flip the white tab up to lock the new card in place.

N o t e :

You cannot use the old screws without the additional shoulder-sleeve as they will

block the CEM3 from being fully inserted.
