(13) Engine control switch The electronic instrument panel is the center for engine control and for information about engine operation. Each component of the instrument panel is described below.Main display module (1) - This module is the main component of the instrument panel. The module receives information from the switches, sensors and other electronic controls on the engine via the CAT Data Link. The module processes the information. The information is output to the gauge clusters and/or the action alarm.Gauge cluster modules (2), (8), and (12) - Every electronic instrument panel is equipped with main display module (1) and gauge cluster module (2). Prime gauge cluster module (8) is optional. The premium gauge cluster module (12) and pyrometer (3) are options that can be obtained in addition to the prime gauge cluster module. The gauge needles and the pyrometer are controlled by information that is processed by the main display module.Pyrometer (3) - The pyrometer displays the exhaust temperature from the exhaust port of each cylinder head. Additionally, the pyrometer can display the temperature of both exhaust stacks."STARTING AID" switch (4) - This switch is used to manually inject ether during start-up. The switch is normally in the "AUTO" position. The automatic position allows the electronic control module (ECM) to automatically control the ether injection. When the operator holds the switch in the "MAN" position, ether is injected according to the strategy that is described in this Operation and Maintenance Manual, "Programmable System Parameters" topic (Operation Section)."SCROLL" switch (5) - The main display module is capable of five different modes of operation. The "SCROLL" switch is used to display the various parameters that are within each mode. See the "Main Display Module" topic."CLEAR/MODE " switch (6) - This switch is used for selecting among the main display module's five modes of operation. This switch is also used for clearing information from the main display module."LH/RH" switch (7) - This toggle switch is used in order to display the exhaust temperature and the inlet air restriction for the left side or the right side of the engine.Emergency Stop button (9) - This button is used to stop the engine quickly in an emergency situation. When this button is pressed, the fuel injection is disabled and the air shutoffs are activated.Action alarm (10) - Annunciation of the alarm informs the operator of an abnormal operating condition or a problem with the monitoring system."ALARM SILENCER" switch (11) - This push button allows the operator to silence the action alarm. The switch will silence the alarm for five minutes. If the condition that initiated the alarm is not corrected within the five minute period, the alarm will sound again.Engine control switch (13) - This switch is used to control the engine operation. The switch has these four positions: "AUTO", "MAN.START", "COOLDOWN/STOP" and "OFF/RESET"."AUTO" - This position enables the operator to control the engine from a remote location."MAN.START" - When the switch is turned to this position, the engine will start. The engine will continue to run until the ECM receives a shut down signal."COOLDOWN/STOP" - This position is used for manual engine stopping. If the cooldown feature is programmed, the engine will operate for a cool down period. After the cooldown, the fuel injection is terminated in order to stop the engine. If the cooldown feature is not programmed, the engine will stop immediately. The power to the control panel is maintained when the switch is in this position."OFF/RESET" - When the switch is turned to this position, power is removed from the control panel. This position will also reset the system if any events have occurred. If the engine is operating, the engine is immediately shut off. This position is not recommended for normal engine shutoff.Gauge Cluster Modules
Every electronic instrument panel is equipped with a main display module and a gauge cluster module. The prime gauge cluster module is optional. The premium gauge cluster module and a pyrometer are options that can be obtained in addition to the prime gauge cluster module.The gauge needles are controlled by information that is processed by the main display module. During normal operation, most of the gauge needles are at the 12 o'clock position. Use the data from the engine commissioning as a baseline for comparison of gauge readings.
Illustration 2 g00799586
The gauge cluster module displays the following parameters:
(1) Engine oil pressure
(2) Jacket water coolant temperature
(3) System voltage
(4) Fuel pressure
Illustration 3 g00799587
The prime gauge cluster module displays the following parameters:
(1) Exhaust temperature (right side and left side)
(2) Inlet air restriction (right side and left side)
(3) Fuel filter differential pressure (restriction)
(4) Oil filter differential pressure (restriction)
Illustration 4 g00799588
The premium gauge cluster module displays the following parameters:
(1) Inlet manifold air pressure (boost pressure)
(2) Aftercooler coolant temperature
(3) Marine transmission oil temperature
(4) Marine transmission oil pressure For more information on the gauges, see this Operation and Maintenance Manual, "Gauges and Indicators" topic (Operation Section).Pyrometer
Illustration 5 g00799589
Pyrometer
(1) Display
(2) Button The pyrometer displays the temperature of the exhaust for the exhaust port of each individual cylinder and for the exhaust stacks. When button (2) is pressed, display (1) identifies the cylinder number (channel) and the corresponding temperature. To advance the display, press the button. To scroll rapidly, keep the button depressed.For engines with 12 cylinders, channels 1 through 12 represent the cylinder numbers. Channels 13 through 16 will be displayed with a default temperature. For all engines, channels 17 and 18 represent the exhaust stacks.Main Display Module
The display on this module includes LED indicators and a liquid crystal display.Indicators
