Information:

Display
The upper display (1) and lower display (2) of the GSC provide information about the generator set.* The 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). The 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 Module SENR5809 for Fault Descriptions.* The lower display (2) shows: system battery voltage, engine hours, engine speed, engine oil pressure, and engine coolant temperature. The value for one of those conditions is displayed 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 that is showing. When engine meter key (3) is pressed, the lower display stops scrolling and continuously shows one particular value. The pointer flashes above the condition whose value is showing. When the engine meter key is pressed a second time, the display returns to scrolling.* The lower display also shows a relay status indicator. When a GSC relay is activated, the corresponding relay indicator (K1, K2, etc.) is shown on lower display (2). When a relay is not activated, the corresponding indicator (K1, K2, etc.) is not shown. Refer to the Service Manual Module SENR5809 for a description of the relay functions.Both the upper and lower display are used for programming functions when in the service mode. For more information, refer to the Service Manual Module SENR5809 for Service Modes.Keypad
The keypad (3) is used to control the information that is shown on upper display (1) and the lower display (2). The seven keys of keypad 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 Module SENR5809 for Service Models. The normal functions of the keys are as follows. Leftmost key (5) - This key only functions when the GSC is in the service mode. This key is used to scroll right. PHASE SELECT key (6) - This key selects which phase of the generator output shows on the GSC upper display. Pressing this key allows the operator to check the voltage, current, and frequency of each phase, one at a time. ENGINE METER key (7) - This key stops the scrolling of engine conditions on the lower display (2). The lower display continuously shows the value for one particular engine condition. The pointer for the particular engine condition flashes to indicate scrolling is stopped. Pressing the key again resumes the scrolling. LAMP TEST key (8) - This key perfumes 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 ON CONTINUOUSLY - every segment of the upper display (1) and the lower display (2) are ON. For the
