(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 system. 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 "AUT" 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
