3-Series

control cards are designed to install
into a control card expansion slot of a 3-Series Control
System
®
device (PRO3 or AV3). The cards can also be
installed into a 3-Series Card Interface device
(CEN-CI3-1 or CEN-CI3-3).
NOTE
: The AV3 requires the CAGE3 Control Card
Expansion Cage accessory to enable use of 3-Series
control cards.
NOTE
: 3-Series control cards are not compatible
with the 2-Series PRO2, AV2, or PAC2 models. Even
when installed in the CAGE3 Control Card Expansion
Cage, the cards are not compatible with any 2-Series
control system.
Installation
Items required to install the 3-Series control cards are
already attached to the unit. The only tools required
are a Phillips screwdriver and a grounding strap. To
install the control card, follow the procedure below.
CAUTION
: 3-Series control cards contain
electrostatic-sensitive devices (ESD); observe
precautions for handling ESDs to avoid damaging the
card.
NOTE
: If the card is being installed into an AV3,
ensure that the CAGE3 Control Card Expansion Cage
accessory is installed before completing this
procedure.
1. Disconnect power from the control system.
2. Use the Phillips screwdriver to remove two
screws and the blank faceplate from the control
system.
3. Align the 3-Series control card guides in the open
slot and slide the control card into position.
4. Firmly press on both ends of the 3-Series control
card faceplate to seat the control card into the
control system connector.
5. Tighten the thumb screws to secure the 3-Series
control card to the control system.
6. Reapply power to the control system.
