Warnings—Faults and Alarms
All Mercury warnings, faults and alarms will be shown regardless of what screen is displayed at the time of the alarm. When an
alarm is activated, the screen will display a window showing the alarm text and warning, along with a brief description of what
action should be taken.
When an alarm fault is triggered, the Mercury tab on the left‑hand side of the screen will display in red and contain the
international warning symbol. When an alarm is activated, the screen will display a window showing the alarm text and warning,
along with a brief description of what action should be taken.
The following images show the alarm window displayed in the center of the screen with the left‑hand side bar in the closed and
opened state.
Critical alarms are usually accompanied with a response from the Mercury Engine Guardian System, which can include
reduced power, reduced maximum RPM, or a forced idle condition. All critical faults give an audible notice to the operator. A
critical fault will sound the warning horn for a continuous six seconds.
