time-delay fuses is selected for the new circuit, the previously used catalog
selection appears as the default.
If the circuit is configured using the Reference an existing circuit on page 721
feature, the values are not used from the CATALOGSEL table but from the
referenced circuit. However, if a new motor is then selected from the Select
Motor
on page 710 dialog box, the CATALOGSEL tables values are checked for
a match.
Add a new circuit
To add a new circuit to Circuit Builder there are three main tasks:
Create the circuit drawing
template on page 2032 (an AutoCAD .dwg file).
Add a reference to this new circuit in the ACE_CIRCS on page 2038 sheet in
the ace_circuit_builder.xls spreadsheet.
Create or modify a
circuit codes on page 2039sheet in the
ace_circuit_builder.xls spreadsheet.
NOTE This exercise demonstrates the capabilities of Circuit Builder and the result
may not necessarily be electrically valid.
Create the circuit template
It is recommended that you read the
Circuit Builder drawing templates on
page 2010 topic before continuing.
A circuit template drawing is an AutoCAD .dwg file that contains the wiring
framework for the circuit. On this wiring framework are positioned special
marker blocks. These marker blocks are configured, using attribute values, to
tell Circuit Builder that some action or decision is required at the insertion
point of each marker block. One marker block might identify where to place
he power disconnecting means for the circuit. Another marker block might
identify that an underlying wire must be appropriately sized to the motor
inserted at yet another marker block on the wire framework of the circuit
template.
The easiest way to create a circuit template is to copy a similar template to a
new name and modify the marker blocks on this copied template. For this
example you copy the circuit template ace_cb1_FVNR_H.dwg to a new name.
It is the main template for a 3-phase, horizontal, full-voltage, non-reversing
motor circuit. You modify this template to create a custom circuit template.
