BASE-VALVE MECHANISM COVER 1774152 - Caterpillar

Control Panel
The control panel is mounted in the generator terminal box. The control panel consists of a main panel with digital gauges, digital AC metering module, and switches, alarm panel module, and ECM engine control module.Optional alarm modules to meet (National Fire Protection Association) NFPA 99 and NFPA 110 requirements are available. Panel illuminating lights and switch, and governor control motor switch are also available as customer options.Main Control Panel
The main control panel may or may not contain all of the components shown. Some optional components may not be required for your application. (1) PL; panel lights.(2) ACM; AC meter module.(3) VAR; voltage adjust rheostat.(4) SP; speed potentiometer or GS; governor switch (optional) (SP shown).(5) AVS; ammeter - voltmeter phase selector switch.(6) LTS; lamp display/test switch.(7) PLS; panel lights switch.(8) ESPB; emergency stop push button.(9) ECS; engine control switch.(10) ALM; alarm module.(11) ECM; engine control module.* Panel lights (1) are controlled by panel lights switch (PLS) (7).* AC meter module ACM (2), contains digital liquid crystal displays for AC volts -(V), frequency - (Hz), and AC amps - (A). These displays indicate the status of the generator output.* Ammeter-voltmeter phase switch (AVS) (5) is used to select phase currents and phase voltages of the generator output to be displayed by the amps and volts display.* Voltage adjust rheostat (VAR) (3), is used to adjust the generator output voltage to the desired level.* Optional governor switch (GS) or speed potentiometer (SP) (4) is used to raise or lower the engine speed when the governor is equipped with a speed adjust motor. If the engine is equipped with a 2301 or other electric governor, a speed potentiometer (SP) is mounted in this location. * Lamp/display test switch (LTS) (6) is used to test all LED's and displays in the test position. All LED's will light and all liquid crystal display digits will read 8888888. If equipped with the optional alarm module (ALM), the lamps will light, and the alarm horn will sound for a maximum of ten seconds.* Emergency stop push button (ESPB) (8) is used to shut down the engine during an emergency situation by shutting off the fuel.* Engine control switch (ECS) (9), determines the status of the control panel. In the Automatic position (3 o'clock), the engine will start automatically whenever the remote initiating contact is closed. The engine will cooldown and shutdown after the initiating contact opens. An adjustable cooldown time is programmed to give a 0 to 30 minute cooldown period before the engine shuts down.In the Manual Run position (6 o'clock), the engine will start and run as long as the ECS switch remains in this position.In the Stop position (9 o'clock), the fuel solenoid shuts the engine down after cooldown.In the Off/Reset position (12 o'clock), the fault LED's are reset and the engine shuts down immediately.Engine Control Module (ECM)
The right side of the control panel contains the engine control module (ECM). This is the "brain" of the system, and also displays fault conditions
