Compact Combination Starter

[Gary.Weber]

We need to know the best way to handle the drawing and the pin list for a compact combination motor starter.  We purchase one part, but there are 4 different symbols that are drawn.  For example, the AB bulletin 190S combination starters include the 140M motor protection circuit breaker and a 100C motor contactor.  Can these be depicted as a single part, or does it need to be added as two separate parts? WBlock?

On the power page, we have the circuit breaker with the circuit breaker overload, and motor starter contact, as well as the NC contact for the overload to the PLC input (see attached image).

On the PLC output page, the motor starter and overload for the circuit breaker (see attached image).

We tried the following without success

1) Add a motor starter coil on the PLC sheet

2) Add a 3 phase motor starter contacts on the high power sheet as a child of the motor starter coil

3) Add a circuit breaker thermal overload on the high power sheet

4) Select the peer of the motor starter coil

Problem: The peer could not be selected since the circuit breaker thermal overload is on a different sheet than the motor starter coil.

Any ideas for a solution?

I have had a similar problem with multi function protection relays.

I got around by using the assembly code to bring in the seperate catalog numbers for the BOM, Having all the various pins in the pinlist of the parent and lots of child blocks.

In the pin list, you have the option of assigning a description to the pins, for example the motor start coil pins wouold be in the COILPINS entry while the pins for the CONTACT would have an entry of 1,L1,L2,*Contact Description.

This description only shows up when you go to the pinlist from the child component editor. The attached screenshot shows the pin selection list for one of the protection relays I use. As you can see, the description shows up as Contact Description=pin1,pin2. In case you are wondering, the Parent (Power Supply) has a third pin which is the Case Earth (C/E) which you can see in the assigned pins.

Hope this information helps you.

Brad - Thank you for the idea. We are going try that. One other question... Is there a way to natively in AutoCAD use a peer on a different sheet?
Thank you,
Gary

Peer-to-Peer requires two parent blocks and won't work between a parent and child.

Note that I haven't used Peer-to-Peer for a fair while and can't check it at the moment.

It used to be that when you inserted a parent and wanted to associate it with another parent, you would select the SCHEMATIC or PANEL button in the component tag section of the dialog box. The Schematic button will bring up a list of components in the same family, along with what sheet they are on.

This way you could select parent components on different sheets to use in the Peer-to-Peer association.

The Panel button brings up a list of compnents mounted on any panel layout dwgs you have in the project. Otherwise it works the same as the Schematic button.
