For some reason the entire text did not post earlier. I will try again
below:
Just insert terminal block symbols into the schematic like normal. Assign
the Tag Strip name and terminal number, such as TB1 terminal number 1, TB1
terminal number 2, etc. Do not assign MFG or CAT to the terminals during
schematic creation. Because of the power of the new Terminal Strip Editor,
just wait until you are creating the panel layout to assign part numbers.
You see, sometimes you may decide to use multi-level blocks after you start
the panel layout and realize that you are running short of horizontal DIN
rail space. You may not know this until you start laying out the panel.
Also, if you are an Integrator, you may not know what brand of terminals
your customer wants until later in the design process.
Be sure you assign wire numbers, either automatically per drawing or
project, or manually in case certain wire numbers must follow a predefined
convention.
When you are laying out your panel and it is time to insert the terminal
strip(s) bring up the Terminal Strip Editor. You will notice that the
Terminal Strip tab is the default view and you will see your terminals
listed as single-level blocks. The wires will appear at left and/or right.
Don't worry about their positions just yet. Place your mouse cursor over
the word Terminal and left-click to sort by terminal number. For some
reason they don't appear sorted by terminal number in the default view.
Next go to the Catalog Code Assignment tab and assign the manufacturer and
catalog number. If you have determined that you need to use multi-level
blocks, choose the part number for the particular brand of multi-level
blocks you want. You can drag your mouse cursor across all of the blocks or
use SHIFT or CTRL to select all blocks at once and assign the MFG and CAT
simultaneously to all (another argument for not assigning one at a time
while creating the schematic). Once you have the blocks selected right
click over any block and select Catalog>Assign. Choose the manufacturer and
catalog number of choice.
Why not go ahead and add the End Stops and End Plates as needed by inserting
spares and choosing the appropriate MFG and CAT for them as well? This way
AutoCAD Electrical will load the proper footprint to depict the end plates
and end stops as well. Note: Be sure to unselect all block and select only
the block above or below where you want to insert a spare. Once you assign
the MFG and CAT to a spare it becomes an end stop or end plate, accordingly.
Next, click on the Terminal Strip tab. You will now notice that your blocks
are double-deck, triple-deck or whatever you chose. See my attached
screenshot. This screenshot shows double-deck blocks denoted by L1 for
level 1 and L2 for level 2. The screenshot has red arrows pointing to L1
and L2. The wires are highlighted in the screenshot. In this example all
of these wires will be connected to the right-hand side of the terminal
strip when inserted vertically or the top if the strip is rotated
horizontally before it is inserted.
Now it is time to assign the terminal numbers and wires to the additional
block level, thus cutting the number of blocks needed in half. This is
tricky so be careful. Read these instructions completely before trying it.
We will assume double-deck terminals for this example. 1>Click on terminal
2, the second double-deck terminal in the list. Click on the top line of
the terminal 2 matrix. While terminal 2 is highlighted go to the lower
right of the dialog box and click the Multi-level Associate Terminals
button. Hang with me here. You have selected terminal 2 to associate to
another terminal; in this case we are associating it to terminal 1. In the
Associate Terminals dialog you will see a list of terminals in the strip.
Click on terminal one, the one you wish to associate terminal 2 with. You
will notice that terminal 1 is assigned to the Upper level. You can change
this later if you wish. Next click the Associate button in this same
dialog. You will notice that terminal 2 is assigned to the Lower level.
Note: These level names can be renamed in this dialog if you prefer
something besides Upper and Lower. If you prefer to have terminal 1 on the
Lower and terminal 2 on the Upper, simply click on terminal 2 and then click
the Move Up button or click terminal 2 and click the Move Down button.
Click OK to exit this dialog.
You will now notice that terminal 2 is now associated with terminal block 1
as its lower level. The previous location of terminal 2 is now blank.
Click on it and delete it, unless you want a spare, unmarked block to appear
in the strip. To delete it, select it, right-click, and select
Spare>Delete. Continue the above procedure to associate 4 to 3, 6 to 5,
etc., erasing the left behind spares as you go.
If you want to move wires from left to right or right to left, simply select
the wire and click the Toggle Terminal Destinations button at the bottom of
the Terminal Strip Editor window. You will now see a new box that allows
you to Toggle External to Internal or Internal to External. External and
Internal are relative terms because very often the external wires attach to
the bottom side of a terminal strip that is inserted horizontally. So just
ignore the text and use the arrows as a guide. Toggle External to Internal
effectively toggles from the right-hand side of the block to the left, while
Toggle Internal to External effectively toggles from the left-hand side of
the block to the right.
Once you have your levels associated and your wires positioned, click the
Layout Preview tab. You will now see an example of how your strip will
look, according to the MFG and CAT assignments you made. By default you
will also see wire numbers appearing on the side of the blocks that you
chose to position them. You can use the menu at the left to add wire type
(wire layer), and even the component where the other end of the wire
attaches (tag:terminal). Bear in mind that you are still looking at the
strip as if it will be inserted vertically. If you want to rotate it so it
will be horizontal on the DIN rail, click the list arrow at the bottom
middle of the dialog labeled Angle On Insert and choose 90. Note: The
layout preview will still show a vertical orientation. This is normal. The
Terminal Strip Editor's Layout Preview doesn't currently show any rotated
views of the terminal strip.
I hope this will help you get familiar with the TSE and how it handles
multi-level blocks.
