12 CEM3 Sensor+ Portable Pack Retrofit Manual
Backplane Settings
Upgrade kit backplanes ship from the factory with all DIP switches in the off (down) position.
You will have to set the DIP switches on the new backplane to match your pack. You will
also have to verify the termination switch settings.
a: Set both termination switches to “Off” (middle position)
b: Using a precision screwdriver, set the DIP switches to match your pack type
according to:
• number of dimmer module slots (6 or 12)
• whether the pack has Advanced Features (AF)
Use the following chart to determine your required DIP switch settings:
“On” position = switch pushed to the top
Replace AF Cards (AF Packs Only)
If your pack supports Advanced Features (AF) you will need to replace the AF card as well.
If you identified your pack as AF when ordering, a new AF card should have been sent with
your upgrade kit. If you do not have the new AF card, you may continue with the retrofit and
you can add AF cards at a later date without having to disassemble the pack. While the
pack is opened, however, it is a good time to easily swap out the cards.
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 card by flipping the white
retainer tab on the card into the down position.
Step 2: Pull the old card out of the slot.
Step 3: Verify that all DIP switches on the new card
are in the “Off” (down) position. This
designates the card as address #1.
Step 4: Slide the new AF card completely into the
vacant slot.
Step 5: Flip the white tab up to lock the new card in
place.
