What alarm status does the GTM VIBS show for a high condition?

The GTM VIBS (Gas Turbine Mechanical Vibrations Monitoring System) categorizes vibration levels through specific alarm statuses, which are designed to alert technicians to potential issues related to turbine vibrations. The 4 alarm status indicates a high condition of vibrations that requires immediate attention by the operating personnel.

This alert helps in the early identification of potential mechanical failures or performance degradation that could arise from excessive vibration levels. Recognizing a 4 alarm status prompts technicians to investigate the root cause of elevated vibrations, ensuring that necessary maintenance or corrective actions can be taken promptly to maintain the integrity and performance of the gas turbine system.

In the context of the other options, the numbers represent varying degrees of alarm severity. However, a 4 alarm specifically denotes the high condition that technicians must focus on to prevent further complications.
