The control panel consists of a main panel with indicators, meters and control switches. This control panel may be equipped with optional modules in order to match the customers' needs and requirements.The left side of the control panel contains the generator set control + (GSC+). This is the main component of the system. The GSC+ displays generator output, fault conditions and key engine parameters. The center section of the control panel may be blank, or contain one or two of the optional alarm modules. The right side of the control panel may be blank, or contain the Caterpillar Monitoring System (35) .The main control panel may or may not contain all of the components which are shown in Illustration 1. Some components are optional. The optional components may not be required for your particular application. Generator Set Control + (1) - The generator set control + (GSC+) is the main component of the EMCP II+. See the topic "Generator Set Control + (GSC+)" in this section.Alarm Module (2) - The alarm module (ALM) is optional. The function of ALM is to provide a visual and audible warning of engine conditions before these conditions become severe enough to shut the engine down or keep the engine from starting. Custom Alarm Module (3) - The custom alarm module (CAM) is optional. The purpose of the CAM is to annunciate faults, alarms or other conditions from customer supplied inputs.Panel Light Switch (4) - The panel lights switch (PLS) turns the panel lights (7) on or off.Pump Stop Switch (5) - The pump stop switch is optional with 3406E and 3412C generator sets only. This push button switch is used with the generator mounted automatic fuel transfer system, if equipped. The pump stop switch is used to manually stop the fuel transfer pump. This switch is latched down when pushed. The red indicator will now be ON. The switch can be reset by pressing the switch again. The red indicator will now be OFF.Start Aid Switch (6) - The start aid switch (SAS) is optional. The SAS is used to inject ether into the engine when you are starting the engine in cold weather conditions. When the SAS is in ON position, the switch energizes the starting aid solenoid valve (SASV) and meters a specific amount of ether in a holding chamber. When the SAS is released, the solenoid releases the ether to the engine.
The engine must be
