Step 5e:
Externally mounted controller cabinet termination.
The first (or last) BCB has to be connected to the controller
to get power and data. Locate one of the 4-pin plugs, either
inserted into the BCB or in the parts bag, Strip the SLAN
cable back to a maximum of 1¼ inches. Be careful not to
nick or cut the insulation of the individual conductors. Strip
each conductor to expose no more than ¼-inch bare wire.
Plug the pre-terminated end of the SLAN/power cable into
the terminal labeled “PWR_C_SLAN-” on the
PRC-E controller enclosure. This connector is found on the left
side of the PRC-E Series controller as shown in
Figure 12
.

When the PRC-E Series controller and BCBs are
wired as illustrated in
Figure 9
, it is important
not to exceed 150 feet total length when using
the recommended 16 AWG cable. If greater than
150 feet of cable is needed, an auxiliary power supply
is required. This can be an integrated power supply
of a PRCEPP panelboard or a PRC auxiliary power
supply, CAT# PRCPS.
The BCBs in a PRCEPP are powered by the integrated power
supply. The SLAN will be daisy-chained from the controller as
in the normal panel using Alpha 1064 2 conductor cables.

BCB startup and troubleshooting
After the BCB modules are installed and wired, each
BCB can be configured to communicate with the
PRC-E Series controller.
Step 1e:
Addressing the BCB.
Each BCB needs a unique address assigned for reliable
SLAN communications.
Figure 14
shows the recommended
addressing scheme; each BCB gets an address from 1 to
8. Refer to
Figure 8
to locate the SLAN address switches
and reference
Figure 14
for positioning of the individual
switches to achieve the required value. Be careful to
observe the switch number as labeled so as to avoid
reversing the values due to top and bottom module location.
This chart is also located on the label affixed to the BCB.

Switches 6 through 8 are not used for the
PRC-E Series application and should be left in
the OFF position.
Step 2e:
Power on and verification.
Apply power to the PRC-E Series controller and verify that
power is routed to each connected BCB. Observe the
“PWR” (power) LED on each BCB and confirm that it is
illuminating red.
If the power LED does not illuminate on any BCB, verify
that there is power from the PRCE controller. This can first
be done by a visual check of the power status LEDs on
controller. See the ”PRC-E Series Front Panel” section on
page 4
. If there is power at the controller, then verify
that all 4-pin connectors are wired correctly.
The following is a brief discussion of the three status LEDs
used to indicate activity and operation of the BCB.
PWRe:
The PWR LED will illuminate whenever the BCB has
sufficient power to operate. If this LED is off, then the other
two status LEDs will not illuminate either. Check the wiring
to ensure that power is delivered to the BCB in question.
LANe:
The LAN LED will blink whenever data is being sent to
the BCB via the SLAN. This LED simply implies that SLAN
communication is present. If the LAN LED is not blinking,
make sure the PWR LED is lit, and then check the SLAN
wiring for crossed or shorted connections.
