WRENCH-TORQUE 3863340 - Caterpillar

Upper display
The upper display (25) 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 (29). The upper display (25) is also used to show the various fault codes for system faults. For more information on fault codes, refer to Systems Operation, Testing and Adjusting, SENR5809, "Electronic Modular Control Panel II (EMCP II) for MUI Engines" or to the Systems Operation, Testing and Adjusting, SENR5398, "Electronic Modular Control Panel II (EMCP II) for EUI Engines".Lower display
The lower display (27) shows the following parameters: system battery voltage, engine hours, engine speed, engine oil pressure, engine coolant temperature and relay status.The value for one of these conditions is shown for two seconds. Then, the display scrolls to the value for the next condition. A small pointer identifies the engine condition that corresponds to the value which is showing. When the engine meter key (30) is pressed, the lower display (27) stops scrolling. The lower display (27) continuously shows one particular value. The pointer flashes when the indicated value is above a predetermined value. When engine meter key (30) is pressed for a second time, the display (27) will return to scrolling.The relay status indicators are on the bottom of the lower display (27). When a GSC relay is activated, the corresponding indicator (K1, K2, etc) is shown on lower display (27). When a relay is not activated, the corresponding indicator (K1, K2, etc) is not shown. For a description of the relay functions, see the Systems Operation, Testing and Adjusting, SENR5809, "Electronic Modular Control Panel II (EMCP II) for MUI Engines" or the Systems Operation, Testing and Adjusting, SENR5398, "Electronic Modular Control Panel II (EMCP II) for EUI Engines".Keypad

(34) Keypad Keypad (34) is used to control the information that is shown on upper display (25) and lower display (27). The seven keys have two sets of functions: normal functions and service functions. For a description of the service functions of the keys, see the Systems Operation, Testing and Adjusting, SENR5809, "Electronic Modular Control Panel II (EMCP II) for MUI Engines" or see the Systems Operation, Testing and Adjusting, SENR5398, "Electronic Modular Control Panel II (EMCP II) for EUI Engines". The normal functions of the keys are described in the following paragraphs.Leftmost Key (28) - This key only functions when the GSC is in service mode. This key is used to scroll right. Phase Select Key (29) - This key selects the phase of the generator output that is displayed on the GSC. When you press this key, the display shows the voltage, current, and frequency of each phase one at a time.Engine Meter Key (30) - This key controls the viewing of engine parameters on the lower display.
