The provided text details the process of verifying the correct operation of power supplies and Power Input Modules (PIMs) in the 3500 Monitoring System. Here is a summary of the key points:

1. Verification Procedure:
   • It is possible to remove the module from the rack while power is applied, following the proper procedure outlined in the Rack Installation and Maintenance Manual (part number 129766-01).
   • System Event List messages will indicate the status of power supplies, including whether they are installed, faulted, or removed.
2. System Event Messages:
   • Two possible messages in the System Event List:
     • Supply OK / Installed: Indicates a power supply has been installed or has transitioned from a Not OK condition to an OK condition.
     • Supply Faulted / Removed: Indicates a power supply has been removed or has transitioned to a Not OK condition.
3. Troubleshooting Steps (If Power Supply OK LED is Off):
   • Verify the supply voltage to the Power Input Module is correct.
   • Ensure the installed Power Input Module type matches the power supply type (e.g., AC Power Input Module with AC power supply).
   • Check for a blown fuse on the Power Input Module and replace it if necessary.
   • If the issue persists, install a new Power Supply.
4. Additional Troubleshooting Steps:
   • If the Power Supply OK LED is on, indicating a faulty original power supply, consider installing a new one.
   • If the problem persists, it may indicate damage to the Power Input Module. In such cases, contacting Bently Nevada LLC for further assistance is recommended.
5. Power Supply Versions – Input Specifications:
   • The text provides specifications for different Power Supply versions (Low Voltage AC, High Voltage AC, and Low Voltage DC) including input voltage range, frequency, input current, input power, efficiency, power factor, and volt-amps.
6. Out of Range Protection:
   • An undervoltage will not harm the supply or the PIM, but an overvoltage will cause the fuse on the PIM to open.
7. Maximum Input Power:
   • Specifies the maximum input power for different power supply versions.
8. Low Voltage AC, High Voltage AC, Low Voltage DC Input Specifications:
   • Detailed input specifications for each power supply version, including voltage range, frequency, input current, input power, efficiency, power factor, and volt-amps.

These details provide users with the necessary information to verify the proper operation of power supplies and troubleshoot issues in the 3500 Monitoring System. Following the outlined steps and specifications ensures correct functioning and helps address potential problems.
