Display
Upper display (1) and lower display (2) of the GSC provide information about the generator set.* Upper display (1) shows AC voltage, current, and frequency of one phase of the generator output. Each phase can be viewed one at a time by pushing phase select key (4). Upper display (1) is also used to show the various fault codes for system faults. For more information on fault codes, refer to the service manual SENR5809, Electronic Modular Control Panel II (EMCP II) For MUI Engines.* Lower display (2) shows system battery voltage, engine hours, engine speed, engine oil pressure, and engine coolant temperature. The value for one of these conditions is shown for two seconds and then the display scrolls to the value for the next condition. A small pointer identifies the engine condition that corresponds to the value that is showing. When the engine meter key (3) is pressed, the lower display (2) stops scrolling and continuously shows one particular value. Now the pointer flashes above the condition whose value is showing. When engine meter key (3) is pressed a second time, the display (3) will return to scrolling.* The relay status indicator is on the lower display also. When a GSC relay is activated, the corresponding relay indicator (K1, K2, etc.) is shown on the lower display (2). When a relay is not activated, the corresponding indicator (K1, K2, etc.) is not shown. For a description of the relay functions, refer to the service manual SENR5809, Electronic Modular Control Panel II (EMCP II) For MUI Engines.Both displays are used for programming functions when in the service mode. For more information, refer to the service manual SENR5809, Electronic Modular Control Panel II (EMCP II) For MUI Engines.Keypad
Keypad (3) is used to control the information that is shown on the upper display (1) and the lower display (2). The seven keys of keypad (3) have two sets of functions, normal functions and service functions. For a description of the service functions of the keys, refer to the service manual SENR5809, Electronic Modular Control Panel II (EMCP II) For MUI Engines.The normal functions of the keys are: Leftmost Key (4) - This key only functions when the GSC is in service mode. This key is used to scroll right. Phase Select Key (5) - Selects which phase of the generator output is displayed on the GSC. Pressing this key allows the operator to check the voltage, current, and frequency of each phase one at a time. Engine Meter Key (6) - Pressing this key stops the scrolling of engine conditions on the lower display (2). One particular engine condition continuously shows its value. The pointer for the particular engine condition flashes to indicate scrolling is stopped. Pressing the key again, resumes the scrolling of engine conditions. Lamp Test Key (7) - Performs a lamp test on the GSC and the optional alarm module for a maximum of ten seconds, if held pressed. On the GSC: the eight fault indicators are
