Chapter 1
Temperature Rise Calculation Software (TRCS) – Tutorial
is tutorial will help you become familiar with the TRCS Temperature Rise Calculation
Software. It will lead you through a sample project.
Please consider this document as complementary information to the Help fi le and the
User Manual, where you will fi nd detailed information about particular topics.
1.1 The Tutorial Project
It is strongly recommended to work through the MCS Star Tutorial fi rst. By completing the
MCS Star tutorial, you will generate a small, versatile busbar assembly project with various
starters types and loadfeeders.
MCS Star provides an “Export” function which generates a kind of “reduced” Bill of Material,
containing only components which will contribute to the temperature rise in the panel,
including their operating current. e component’s power loss data for a wide range of
Rockwell Automation products are provided in a database within TRCS.
For more information about the temperature rise calculation model consult the Help fi le,
User Manual and the standard IEC 60890.
We will use the data exported from MCS Star in this Tutorial.

Chapter 2
Start with Your First TRCS Project
Start the Temperature Rise Calculation Software (TRCS).
In the startup window, select the [ New Project ] button.
Enter the name of the project, then select the [ OK ] button.
Select the menu item “Databases/Person in charge”.
3
Start with
Your First Project
(co ntin ued )
In the following window, select the [ + Add Dataset ] button, then enter your personal data
into the new row.
In the “Project data” tab, enter the customer data per the example below.
Select the button in the “Person in charge” section.
4
Start with
Your First Project
(co ntin ued )
If the data for “Customer” and “Person in charge” is already entered, it can be retrieved from the
database by selecting the button in the corresponding area.
Newly entered or amended data can be stored in the database by selecting the button.
e data entry in the “Project data” tab is now complete. Please save your work before you go
forward to the next tab.
Notes:
If you want to save intermediate steps or multiple versions of a project, select the •
[Save as...] button and save it under a new fi lename.
e program creates the sample project fi le name “Example” every time you start TRCS. •
If you want to save changes on the “Example” project, select [Save as...] and enter a
new fi le name.

2.1
“Environmental
Conditions” Tab
Before you enter the environmental conditions, you may want to change some program settings,
like units of measure or temperature. Select the menu option “Extra /Settings...”
Make your changes and select the [ OK ] button.
Notes:
Rockwell Automation provides enclosure databases from multiple suppliers with the software. However,
if your preferred supplier is not included or if you have some custom enclosure sizes, you can create your
own enclosure database.
e component database provided with the software contains nearly 1,900 records, representing more
than 15,000 individual Rockwell Automation components with their power loss data. If you regularly
need some additional products, just create your own User Components Database.
