This section describes the 129-4053 Control Panel. If your engine is equipped with a different control panel, refer to SEBU6918, SR4B Generators and Control Panels, or SENU6918, 130-3786 Generator Control Panel Supplement.EMCP II Control Panel
The generator set Electronic Modular Control Panel II (EMCP II) is located on top of the generator regulator and terminal box housing. The control panel consists of a main panel with indicators, meters, and control switches. The control panel may be equipped with optional modules to match the customer's needs and requirements. The right side may be blank, or contain one of the alarm modules, or a synchronizing lights module.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.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.
(1) Optional panel lights(2) optional governor switch (shown) or speed potentiometer(3) optional starting aid switch(4) engine control switch(5) optional alarm module (shown)(6) optional custom alarm module (shown) or synchronizing lights module(7) voltage adjust rheostat(8) emergency stop push button(9) optional panel light switch(10) generator set control* The panel lights (PL) (1) are controlled by the panel light switch (PLS) (9).* The voltage adjust rheostat (VAR) (7), 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) (8) 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
