The eight fault indicators are used in order to show
the fault in the engine. The eight fault indicators are
also used to describe the fault in the engine. The fault
indicators are divided into three groups. The three
groups are listed below:
• fault alarm indicator (22)
• fault shutdown indicator (21)
• dedicated shutdown indicators (23)
The yellow fault alarm indicator (22) FLASHES when
the GSC detects an alarm fault. The alarm fault does
not cause the engine status to change. The engine
can be started. The engine will continue operating,
only if the engine is running at the time of the alarm
fault. Fault alarm indicator (22) is accompanied by an
alarm fault code that is shown on the upper display
(25) when the alarm codes key (26) is pressed. For
the descriptions of the fault codes, refer to the
Systems Operation, Testing and Adjusting,
SENR5809, “Electronic Modular Control Panel II
(EMCP II) For MUI Engines” or to the Systems
Operation, Testing and Adjusting, SENR5398,
“Electronic Modular Control Panel II (EMCP II) For
EUI Engines”.
The red fault shutdown indicator (21) FLASHES
when the GSC detects a shutdown fault. The engine
will be shut down if the engine is running. The engine
will not be allowed to start. Fault shutdown indicator
(21) is accompanied by a fault code that is
immediately shown on the upper display (25). For the
descriptions of the fault codes, refer to the Systems
Operation, Testing and Adjusting, SENR5809,
“Electronic Modular Control Panel II (EMCP II) For
MUI Engines” or to the Systems Operation, Testing
and Adjusting, SENR5398, “Electronic Modular
Control Panel II (EMCP II) For EUI Engines”.
The red dedicated shutdown indicators (23)
represent the following shutdown faults: low oil
pressure, emergency stop, high water temperature,
engine overspeed, low coolant level and engine
overcrank. When the GSC detects a fault in one of
these areas, the dedicated shutdown indicator (that
corresponds to the fault) FLASHES. The engine is
shutdown if the engine is running, and the engine is
not allowed to start. No fault codes are associated
with the dedicated shutdown indicators because
each indicator has a descriptive label.
Many of the dedicated shutdown faults depend on
certain setpoints in the GSC. For the descriptions of
the fault codes, refer to the Systems Operation,
Testing and Adjusting, SENR5809, “Electronic
Modular Control Panel II (EMCP II) For MUI Engines”
or to the Systems Operation, Testing and Adjusting,
SENR5398, “Electronic Modular Control Panel II
(EMCP II) For EUI Engines”.
The conditions that are required to activate the
dedicated fault shutdowns and the results of each
dedicated fault are in the following list.
Low Oil Pressure – The engine oil pressure drops
below the setpoints for low oil pressure shutdown
that are programmed into the GSC. There are two
low oil pressure setpoints. One setpoint is used when
the engine is at idle speed. The other setpoint is used
when the engine is at rated speed. When a low oil
pressure fault occurs, the low oil pressure indicator
FLASHES, and the engine is shut down. The engine
is not allowed to start until the fault is corrected.
Emergency Stop – The operator presses the
emergency stop push button (ESPB) on the front
panel. When an emergency stop condition occurs,
the emergency stop indicator FLASHES and the
engine is shut down. The engine is not allowed to
start until the condition is corrected.
High Water Temperature – The engine coolant
temperature rises above the setpoint for high water
temperature shutdown that is programmed into the
GSC. When the high water temperature fault occurs,
the high water temperature indicator FLASHES. The
engine is shutdown and the engine is not allowed to
start until the fault is corrected.
Engine Overspeed – The engine speed exceeds the
setpoint for engine overspeed that is programmed
