Main Control Panel
The main control panel may or may not contain all of the components shown. Some components are optional, and may not be required for your particular application.
Optional panel lights (1), optional governor switch (shown) or speed potentiometer (2), optional starting aid switch (3), engine control switch (4), optional alarm module (shown) or synchronizing lights module (5), voltage adjust rheostat (6), emergency stop push button (7), generator set control (8), and optional panel light switch (9).* The panel lights (PL) (1) are controlled by the panel light switch (PLS) (9).* The voltage adjust rheostat (VAR) (6), is used to adjust the generator output voltage.* The optional governor switch (GS) or speed potentiometer (SP) (2) is used to raise or lower the engine speed. If the governor is equipped with a speed adjust motor, the governor switch is mounted in this location. If the engine is equipped with an electric governor, a speed potentiometer is mounted in this location.* The starting aid switch (SAS) (3) is used to inject ether into the engine for starting in cold weather conditions. When the starting aid switch is moved to the ON position, the switch energizes and meters a specific amount of ether in a holding chamber. When the switch is released, the solenoid releases the ether to the engine.* The emergency stop push button (ESPB) (7) is used to shut down the engine during an emergency situation. The ESPB shuts off the fuel and activates the optional air shutoff (if equipped).* The engine control switch (ECS) (4), 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 shutdown after the initiating contact opens and adjustable cool down time has elapsed. The cool down time can be programmed to give a 0 to 30 minute cool down period before the engine shuts down.When the ECS is in the Manual Run position (6 o'clock), the engine will start and run as long as the ECS remains in this position.When the ECS is in the Stop position (9 o'clock), the fuel solenoid shuts the engine down, after a programmable cool down time period.When the ECS is in the Off/Reset position (12 o'clock), the fault lights are reset and the engine shuts down immediately.Generator Set Control (GSC)
The left side of the control panel contains the Generator Set Control (GSC). This is the "main" component of the system, and also displays generator output, generator set functions, fault conditions, and key engine parameters.The GSC accepts information from the operator, magnetic pickup, oil pressure and water temperature sensors, and optional remote sources. The accept information is used to determine the "on/off" state of the engine's air, fuel, and starter.In the very basic operating conditions, the GSC receives a signal to run the generator set. The GSC turns on the engine's fuel and starter. When the engine speed reaches the crank termination speed, the starter is disengaged. When the GSC receives a signal to stop the engine, it shuts the fuel off.GSC Features and Functions:
* Controls normal starting and stopping of the engine.* Shows engine conditions and generator output information on two displays. The displays also show fault codes and GSC programming information.* Monitors the system for faults. If a fault occurs, the GSC provides a fault alarm annunciation, or performs a controlled fault shutdown. The GSC uses indicators and displays to describe the fault.* Contains programmable features for certain applications or customer requirements.* Cycle Crank - The GSC can be programmed to crank-rest-crank, etc. for adjustable time periods. Refer to the Service Manual Module SENR5809 for programming instructions.* 2301 or 2301A Control - When the engine oil pressure increases past the low oil pressure set point, the GSC will indicate to the governor that it should increase engine speed from IDLE to RATED rpm.* Cool Down - Upon receiving a signal to perform a normal shutdown, the GSC will wait a preprogramming amount of time before shutting the engine down by means of the fuel control.* Automatic Operation - While in the automatic mode, the GSC can be started by a remote initiate signal (contact closure). Upon loss of the signal (contact opening), the GSC will perform a normal shutdown.* Alarm Module Communication - The GSC can transmit fault and alarm conditions to an alarm module.* Power Down - The Electronic Modular Control Panel II (EMCP II) system is designed to remove power from the GSC when in the off/reset mode and the proper jumper wire is removed. The GSC will not allow the power down until the crank termination relay and the fuel control relay are both "off" for about 70 seconds. If the wire is not removed, the GSC will remain powered up.Refer to the Service Manual Module SENR5809 for the wiring diagram and the jumper wire location.* Fuel Solenoid Type - The GSC can be programmed to work with either an energized to run (ETR) fuel system or an energized to shutdown (ETS) fuel system.* Customer Communication - The GSC is provided with connections for an optional Customer Communications Module (CCM). The CCM will allow two way communication between the EMCP II and the operator. A customer-supplied personal computer (PC), or other device with a RS-232C port, interfaces with the CCM.Fault Indicators
The eight fault indicators (1-8), located on the front of the GSC, are used to show and describe a fault that is present. The first seven are red fault shutdown indicators, and the eighth is a yellow fault alarm indicator.* The yellow FAULT ALARM indicator (8) flashes when the GSC detects a fault that is an alarm condition. The engine continues to run and start. The FAULT ALARM indicator is accompanied by an alarm fault code, shown on the upper display when the alarm codes key is pressed. Refer to SENR5809 for fault code descriptions.* The red FAULT SHUTDOWN indicator (7) flashes when the GSC detects a fault that is a shutdown condition. The engine
