A documented process for verifying that an instrumentation loop has been installed, wired and configured correctly before commissioning.
A Loop Check Procedure defines the steps used to verify the complete operation of an instrumentation or control loop from the field device through associated wiring, control systems and operator interfaces. It confirms that signals are transmitted correctly, devices respond as intended and the loop functions safely before commissioning or plant startup.
Loop Check Procedures verify the correct installation and functional operation of instrumentation and control loops prior to commissioning.
Loop checks are typically performed after installation and before commissioning to identify wiring, configuration or functional issues that could affect safe and reliable plant operation.
A Loop Check Procedure verifies the operation of an individual instrumentation loop, whereas commissioning encompasses the broader verification and startup of complete systems and facilities.
