CHANGE THE BENSHAW INC., RediStart MICRO™ SOFTWARE CONFIGURATION IF NECESSARY — Ben- shaw starter configurations are checked and modified from the menus in the Benshaw Redistart MICRO Default Display. See Fig. 32 and Table 6 for default display and menu items. To ac- cess the menus to perform checks and modifications, the Ben- shaw starter must be powered up and its self-test must have been successfully completed. The self-test takes place automat- ically after power-up. Current transformer ratio configurations and hardware switch settings checks are performed in the MENU1 display screen. See Table 7 for menu structure and Table 8 for switch settings.

1.Press the MENU softkey until the desired menu is se- lected on the display.

2.Press the ENTER softkey to access the displayed menu items (Table 6).

3.Use the ↓ or ↑ arrow keys to scroll between menu items until the desired item is reached on the display.

4.Press the ENTER softkey to access the value to be changed.

5.Use the ↑ or ↓ arrow keys to adjust the new displayed value. The ↑ key increases the value while the ↓ key decreases the value. Holding the arrow key will progres- sively increase the rate of change. The value will stop changing when either the factory set minimum or maxi- mum value is reached. To make fine adjustments press and release the arrow key.

6.When the correct value has been selected, press the ENTER key to store the new configuration. At this point, there are two options. The MENU key will return the display to the main display. The ↑ or ↓ arrow keys will move the display to the next menu item. When fin- ished press the MENU key to return to the main display.

To view other settings and troubleshooting guide consult the Benshaw RediStart MICRO instructional manual included in the starter.
