Creating relay with a couple of coils.

[Anonymous]

Hi everyone! I have got a problem with inserting a overload 3-pole relay. It got 3 coils as we can see:

and when we look on its pins we see only two contacts:

so to assign pins of these three coil I need to write in pin list this:

which means 1 coil and 2 NO contacts.
So the question is how to create this component in such way that it will have more than one coil the 2-nd image?

Sounds like you only have two connection points (TERM01, TERM02).

You need to have six connection points... one at each line and load side.

That pin list should be per phase. In order to access the pins on the child components, you'll need to double click on them directly.

I don't think you can edit pins for any child symbol through its parent like this.

The dialog is correct...

ACADE inserts multipole objects using a combination of parent & child blocks.

However, to get the terminal numbers correct, you currently have to edit each block.

The dialog box you posted is for the parent which only has the 2 wire connection points.

You will have to edit each of the children and either type their numbers in or click on list to access the pinlist data from the parent.

The reason ACADE uses the Parent/Child setup is that it allows flexibility on wire spacing.

For example, a main bus could be spaced at 20, the circuits teeing off at 15 or 10 and yet use the same set of blocks on both sizes without havingto do any editing.

There is no facility to edit one block and have the terminals for other associated blocks available for editing.

This feature is the subject of a post on the Idea Station.

What Brad has said is very true.  And probably best practice for most people.  However, if you are working within a closed system like I am, and your spacing is always the same, you can indeed make multiple coil symbols just fine.  The one shown below is a child symbol, but I have parent symbols made in a similar manner.  You just have to have the terminal attributes for all three (or more) connections.  The larger image shows the symbol in circuit and the inset, grey portion is a screenshot from the Symbol Builder.

Hope this helps.

Here's the Edit dialog and a peek at the pinlist entries.  My pinlists are huge on these smart relays, but worth it to put together once.  With that 3 phase coil symbol I can set all the pins and coil descriptors with one click in the pinlist.

I have just made this by my own and then saw your answer! Also there is a little notice about spacing between wires.... When you change spacing you need to change scale anyway and by changing scale the element created by you with 3 coils together will fit just perfect! So good luck for everyone and thanks for paying attention to this theme!!!
