Where can total run time for the coolant heater be found during a 400 hour mechanical inspection on the BPU?

The total run time for the coolant heater during a 400-hour mechanical inspection on the BPU can be found in the service adjustment screen on the DCS. This screen typically provides detailed operational data and metrics related to various components of the system, including runtime statistics for heaters and other equipment.

The service adjustment screen is designed to give technicians and engineers quick access to important functionality and performance indicators, enabling effective monitoring and maintenance of the unit. Accessing this data is essential for assessing performance, scheduling maintenance, and ensuring overall efficiency.

While the maintenance log may contain historical data, it does not offer real-time or specific runtime metrics. The user manual and troubleshooting guide are useful for understanding operational procedures and solving issues, but neither indicates live operational metrics like total run time. Therefore, the service adjustment screen on the DCS is the most appropriate source for this specific information.
