User Guide
GETTING STARTED
The COMMANDER 350 can be configured and made ready for operation in three easy steps.
This 'Getting Started' guide provides an overview of these steps and, where necessary, refers to
the relevant section of the manual.
Step 1 – Decide on the Application Template and the
Output Configuration required
Step 2 – Connect the process inputs and outputs
Step 3 – Power up the instrument, set the template number and the
output configuration details
Your COMMANDER 350 is now ready for operation
Step 1 – Application Template and Output Configuration
• Choose the Template which best suits your application from the list in Table A, located on the
rear fold-out.
• Choose the Control Output Type required from the list of options in Table B on the rear
foldout.
Step 2 – Electrical Connections
Using the labels on the back of the instrument as a guide, connect the process inputs, outputs
and power supplies. Refer to Section 5.2 of this manual (Electrical Installation) for more
information.
