Overview of power check tools
You can add information to your schematic components to indicate power
source and load values using the supplied Power Check tools. Once these
values have been added, you can run the Power Load Check Report to scan
the wire interconnections and report if there is too much load on a given
power source.
There are 3 tools to use for checking power source/load:
Marks a component with a power source and load
value. The value is added to an AutoCAD Electrical
Add/Edit Power Source/Load values
connection attribute. This dialog box contains a list
of available connection points. If you select near the
connection point for the power value it will be pre-
selected in the dialog box. Enter the power source
and load value and an optional units value. These
values will be saved on the connection point as invis-
ible xdata.
Marks a component with a PASSPWR flag. The
PASSPWR flag instructs the Power Report to pass
Set Pass Power
through the marked component when calculating
the load on a given source. If a component carries
the PASSPWR flag the Power Report program will
pass through the component and continue looking
for load values on the network
Looks for any components assigned as a power
source and then follows any wires connected to that
Power Load Check Report
terminal. When a load is hit, it stops reading on that
wire segment and doesn't search past the load. For
example, if you apply a supply value to the left power
bus on a ladder, there are a bunch of pilot lights and
relay coils in the ladder. AutoCAD Electrical goes
down the left bus and checks each connected rung.
It reads through contact and terminals, but when it
hits a load on a rung, it accumulates the load value
(if present) and stops going any further on that rung.
The utility will still check the other rungs tied to the
left-hand bus and try to find more loads.
