BCU Installation
CAUTION!
♦
Do not remove the plastic insulation shield from the back of the BCU PCB. If the
shield comes off, do not allow the back of the PCB to contact metal.
♦
The BCU PCBs are shipped from the factory with the battery jumper in the “Off”
position. Ensure it is moved to the “On” position before installing the BCU to protect
customer configuration information stored in the BCU RAM.
♦
The power supply must be off when installing the BCU PCB or damage to the board
could result.
1. Set the battery jumper, “BATT”, on the B1CU, B2CAU/B2CBU, B3CAU/B3CBU or B5CBU,
to the “On” position (see
2. Ensure the BCU has been configured for the appropriate hardware options (i.e., BRCS or
RKYS). See
.
3. Insert the B1CU, B2CBU,
B3CBU, or B5CBU (1, 2 or 3)
into the “B101” slot in the
Base Cabinet. If B1CU and
RSIU is installed, you must
also install a ribbon cable
between them (
).
Ensure the component side of
the BCU PCB is facing right
when installing it in the Base
Cabinet.
4. Insert the B2CAU, B3CAU, or
B5CAU PCB into slot B102.
5. After installing the BCU
PCBs, gently pull it outward.
If the connectors are properly
mated, a slight resistance will
be felt.
6. Connect the supplied ribbon
cables between B1CU,
B2CAU/B2CBU, B3CAU/
B3CBU and B5CAU/B5CBU
and RSIU, if installed.
Note
Do not adjust the C14 or
C15 trimmer capacitor.
The capacitor is factory-
calibrated.
