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
softkey until the desired menu is se-
lected on the display.
2. Press the
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
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
key to store the new configuration. At this
point, there are two options. The
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
key to return to the main display.
To view other settings and troubleshooting guide consult the
Benshaw RediStart MICRO instructional manual included in
