ABB article 07KT97 identifies 07KT97 as a AC31 basic unit. It executes the controller program and coordinates its onboard I/O. Use it only in the documented ABB Advant Controller 31 automation systems position whose engineering record names this exact execution.
07KT97 must remain matched to ABB Advant Controller 31 automation systems. Record the receiving equipment, connector assignment and installed settings before removal.
After installation, verify power and diagnostics first, then prove communication or I/O status and the assigned function under a controlled test before process release.
This AC31 basic unit executes the controller program and coordinates its onboard I/O. Match the complete ABB identity and receiving-equipment record before installation.
Keep 07KT97 on the documented signal, bus or power path. Preserve connector orientation, installed position and approved settings.
After replacement, compare diagnostics with the saved baseline and prove the assigned AC31 basic unit function under controlled test conditions.
Trace the documented field, bus or power path through the installed AC31 basic unit. Verify terminal ownership, connector orientation and receiving-equipment reference before energization.
Capture the installed diagnostic baseline before exchange. After startup, compare status indications and prove that the assigned function responds correctly before removing the test boundary.
Supply condition and lifecycle status are confirmed for the exact 07KT97 at quotation.
Verify the complete ABB identity, included items and receiving-equipment match before installation.
