Quick answer: The NO POWER SUPPLY INST trouble indicates that the panel's main power supply (AMPS-24) has not been correctly identified in programming or is not communicating.
What to check:
Programming Address: Ensure the AMPS-24 AC fail address (base address plus one) has been correctly entered in the system configuration (Page 35) [1].
Device Configuration: Verify that all four main power supply addresses are programmed with MOD TYPE=Monitor, TYPE CODE LABEL=Power Monitor, and FLASHSCAN=PS Mon (Page 35) [1].
Trouble Reporting: Confirm the AMPS-24 is configured for "Trouble Reporting" in the settings (Page 35) [1].
SLC Loop: Check that the SLC loop is physically installed and communicating with the power supply (Page 35) [1].
Hardware Connection: Ensure the FACP is properly connected to the AMPS-24, as the CPU2-3030 requires this specific power supply to operate (Page 4) [2].
Verify with current documentation before making changes.
