Which alarm is shown if VARTOMS fails?

Which alarm is shown if VARTOMS fails?

• A. VAR NR
• B. Overheat
• C. Low oil pressure
• D. No alert

Answer: (A)

The main idea is that alarms point to the specific subsystem that isn’t operating correctly. If the VARTOMS module stops functioning or stops communicating, the system flags the VAR NR alarm to show that the VAR control channel is not responding. This tells the operator that the reactive power/voltage regulation control loop is down and needs attention. The other alarms reflect different conditions (high temperature or low oil pressure) and would only come up if those actual physical faults occurred, not simply from a VARTOMS failure. So the VAR NR alert is the appropriate indication of a VARTOMS failure.
