Marine Engine Control Panel
The Marine Engine Control Panel contains the following components:
A personal computer (PC) that displays the operating information
A minimum protection backup relay system
Control switches for starting the engine
Control switches for stopping the engine
The engine speed switch
A Programmable Logic ControllerPersonal Computer
The PC display provides the engine status for the operator.Control Switches
The following controls are located on the Marine Engine Control Panel:
"EMERGENCY STOP" button
"OFF/RESET-LOCAL-REMOTE" switch
"PRELUBE-RUN-START" switch
"FUEL CONTROL" switch
"HORN SILENCE-LAMP TEST" switchThe control switch on the Marine Engine Control Panel permits local control of the engine or remote control of the engine. This switch can also be placed in the OFF/RESET position. The "FUEL CONTROL" switch can be placed in the OFF position or the ON position.Weight of the Marine Monitoring System

The programmable logic controller provides complete monitoring and control for a Caterpillar 3600 Engine. The basic modular programmable logic controller consists of the following components:
Power Supply
Central Processing Unit Module (CPU)
Chassis
Input Modules
Output Modules
Engine Speed SwitchThe programmable logic controller is the computer that conducts the following engine functions:
Control
Monitor
ProtectionThe CPU in the programmable logic controller contains the software that controls programmable logic controller behavior.The following components are used as engine sensors: contactors, thermocouples, resistance temperature detectors (RTDS) and transducers.Power Supply
The power supply delivers 24 VDC for the following components: the CPU, the chassis, the control panel, the input modules and the output modules. The 24 VDC is typically provided by a battery set.Central Processing Unit Module
The operator can configure the memory. The operator can configure the memory for data. The operator can also configure the memory for the storage of programs. The memory size is adjustable from 1K to 64K. The CPU is supported by a variety of modules. These modules include digital modules, analog modules, and smart modules. The CPU is seated in slot 0 of the programmable logic controller chassis.Discrete Input Modules
The discrete input modules are in the following list:
Thermocouple Module
RTD Input Module
Digital Modules
Analog ModulesWhen you apply a voltage to the channel, the relay is energized. An energized input closes all of the contacts that are normally open. An energized input will open all of the contacts that are normally closed. Digital modules are used to determine whether a circuit is ON/OFF. A number of modules are available. The MMS modules have sixteen channels.Discrete Output Modules
The programmable logic controller discrete output modules consist of analog modules and digital modules. Voltage control is provided by the output modules. A module provides power for the following list of functions: energizing the lamps, energizing the relays, energizing the fuel shutoff solenoid and energizing the air shutoff solenoid.Engine Speed Switch
The speed switch accepts a signal from the magnetic pickup. The magnetic pickup is mounted on the engine. The speed switch determines the engine speed from the signal. The speed switch provides
