(8) Panel light switch (PLS)
(9) Emergency stop push button (ESPB)
(10) Voltage-adjust rheostat (VAR)The electronic modular control panel II (EMCP II) is located above the generator distribution housing. The control panel consists of a main panel with indicators, meters, and control switches. This control panel may be equipped with optional modules to match the customer needs and requirements.The left side of the control panel contains the Generator Set Control (GSC). This GSC is the main component of the system. The GSC displays the following information: generator output, fault conditions, and key engine parameters. The center section of the control panel contains switches and an optional alarm module. The right side of the control panel may be blank. The right side of the control panel may contain the Synchronizing Lights Module or the Custom Alarm Module.The main control panel may not contain all 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.Diagnostic Reset Switch (2) - The diagnostic reset switch is a toggle switch that is used to clear diagnostic codes from the engine control module. The switch cannot clear individual codes. Use of the switch will clear all the codes that are active in the engine control module.Note: Do not clear the codes until the problems that caused the codes are addressed.Engine Control Switch (3) - The engine control switch (ECS) determines the status of the control panel. In the AUTOMATIC position (3 o'clock), the engine will start automatically whenever a remote initiating contact is closed. The engine will shut down after two of the following conditions are met:
The initiating contact opens.
A programmable cooldown period has elapsed.The cooldown period can be programmed to give a 0 to 30 minute cooldown period before the engine shuts down.In the MANUAL START position (6 o'clock), the engine will start and the engine will run as long as the ECS remains in this position.In the STOP position (9 o'clock), the fuel solenoid shuts down the engine after a programmable cool down time period has elapsed.In the OFF/RESET position (12 o'clock), the fault lights are reset and the engine shuts down immediately.Panel Lights (4) - Panel lights (PL) are controlled by panel lights switch (8). The panel lights switch (8) is an ON/OFF switch.Alarm Module (5) - 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 down the engine or keep the engine from starting.Synchronizing Lights Module (6) or Custom Alarm Module (6) - The synchronizing lights module uses synchronizing lights for paralleling the generator sets. The synchronizing lights module is optional. The custom alarm module (CAM) may be installed in the same opening on the control panel. The CAM annunciates faults, alarms, or other conditions from customer supplied inputs.Speed Potentiometer (7) - The speed potentiometer (SP) is optional. The SP can be used with the generator set that has an electronic governor. When the governor is equipped with a speed adjusting motor, the governor switch (GS) can be mounted instead of the SP. The GS is used to raise or to lower the engine speed and the engine frequency. The GS is also an option.Panel Light Switch (8) - The panel lights switch (PLS) turns the panel lights (4) on or off.Emergency Stop Push Button (9) - The emergency stop push button (ESPB) is used to shut down the engine during an emergency situation. The ESPB shuts off the fuel. The ESPB also activates the optional air shutoff, if equipped.Voltage Adjust Rheostat (10) - The voltage adjust rheostat (VAR) is used to adjust the generator output voltage to the desired level.Below, you can find the descriptions of the following main modules of the EMCP II:

The location of the GSC on the EMCP II
The left side of the control panel contains the generator set control (GSC). The GSC is the main component of the system. The GSC displays the following information: generator output, generator set functions, fault conditions, and key engine parameters. The GSC accepts information from the following sources: operator, engine speed sensor, engine oil pressure sensor, water temperature sensor, and optional remote sources. This information is used to determine the "on/off" state of the engine air, fuel, and starter.During normal operating conditions, the GSC receives a signal to run the generator set. The GSC turns on the engine' fuel and the engine starter. When the engine speed reaches the crank termination speed, the starter is disengaged. When the GSC receives a signal to stop the engine, the GSC shuts off the fuel.The functions of the GSC are listed below:
The GSC controls the starting and the stopping of the engine (normal conditions).
The GSC shows engine conditions and generator output information on two displays. The displays also show fault codes and GSC programming information.
The GSC monitors the system for faults. If a fault occurs, the GSC performs a controlled fault shutdown or the GSC provides a fault alarm annunciation. The GSC uses indicators and displays to describe the fault.
The GSC contains programmable features for certain applications or customer requirements.The features of the GSC are listed below:
Cycle Crank: The GSC can be programmed to crank for adjustable time periods.
Governor Control: When the engine oil pressure increases past the low oil pressure setpoint, the GSC signals the governor to increase the engine speed from idle rpm to rated RPM.
Cooldown: Upon receiving a signal to perform a normal shutdown,
