The user interface operates in two modes—Parameter
Select Mode and Parameter Edit Mode.
The Parameter Select Mode provides the user selection
of viewing and editing parameters. This mode is active
when the 2-digit value display is flashing (blinks). The
value is the parameter identification (ID) number. The
governor controller label lists each user-adjustable
parameter and the corresponding ID number.
The Parameter Edit Mode provides the user with the
selected parameter's value and allows the changing of a
value. This mode is active when the 2-digit value display
is steady on. The value displayed is the selected
parameter's current value. The decimal point display
has several meanings:
D
Decimal point flashing indicates the value can be
edited.
D
Decimal point not flashing indicates the value cannot
be edited. The selected parameter is locked and
values are viewable only. This situation occurs when
the password protection is active and the unlocking
code has not been entered.

The right digit's decimal point is ON—the lower two
digits of a parameter's 4-digit value are displayed.

digits of a parameter are always view only and cannot
be modified directly. The upper two digits will change
