The parameters are preset at the factory or the parameters can be modified in order to meet the specific requirements on the site. Certain system parameters can also be monitored on the display (1) of the DVR. Keypad (5) is used to change the information that is shown on the display. J1 connector (6) is used to join the DVR to a personal computer. Screw terminals (7) are used to join the DVR to the generator and various customer options.Adjustment Procedure for the Voltage Regulators
Refer to the Specifications, Systems Operation, Testing and Adjusting, SENR5833, "Digital Voltage Regulator".The digital voltage regulator (DVR) can be set up for a specific application by using the configured parameters. Parameters are preset at the factory. Parameters may need to be adjusted in order to meet the specific requirements of a site. The DVR also detects faults. When a fault is detected, the DVR sets the appropriate alarm or caution. Certain system parameters can also be monitored on the display of the DVR.Display (1) and keypad (5) are used to select parameter values. The display and the keypad are also used to manipulate the parameter values that control the operation of the digital voltage regulator. The display of the digital voltage regulator has four digits. When one of these digits is a colon, the number that is showing is a parameter code. When a colon is not present, the number that is showing is a parameter value. A decimal point in the display is used to indicate the precision of the parameter value.Keypad (5) has three keys. The keys are listed below.
Function key (2)
Scroll down key (3)
Scroll up key (4)Display (1) has two modes. These modes are the parameter code mode and the parameter value mode. Function key (2) is used to toggle back and forth between the two modes. Scroll down key (3) and scroll up key (4) are used to change the display's value. The scroll down key will decrease the parameter number or the scroll down key will decrease the value. The scroll up key will increase the parameter number or the scroll up key will increase the value.

0101 The operation of display (1) and keypad (5) is shown in Table 1. Pressing function key (2) toggles the display between the two columns of the table (parameter code and parameter value). The display is in the parameter code mode when a colon is present. If a colon is not present, the display is in parameter value mode.When you press scroll up key (3), the number that is displayed will increase to the next higher
