6 — PROGRAMMER OPERATION
The two
CHANGE
VALUE
arrow keys are used to increase or decrease the value of a
selected menu item. Like the
SCROLL
DISPLAY
arrow keys, the
CHANGE
VALUE
arrow
keys can be pressed repeatedly or be held down. The longer a key is held, the faster
the parameter changes. This allows rapid changing of any parameter.
An LED on each
CHANGE
VALUE
arrow key indicates whether the key is active
and whether change is permissable. When the value of a parameter is being
increased, the LED on the “up”
CHANGE
VALUE
key is on until you reach the
maximum value for that parameter. When the LED goes off, you cannot increase
the value.
The
MORE
INFO
key has three functions: (1) to display more information about
the selected item, (2) to access the Special Program and Special Diagnostics
modes (when used together with the
PROGRAM
and
DIAGNOSTICS
keys), and (3)
to initiate certain commands (such as the Self Test).
“More information” is available in all of the programmer operating modes.
After using the
MORE
INFO
key to display additional information about the
selected item, press the
MORE
INFO
key again to return to the original list.

In the
Program
mode, accessed by pressing the
PROGRAM
key, all the adjustable
parameters and features of the controller are displayed (four at a time), along with
their present settings. The setting of the selected item—the item at the top of the
display, with the flashing arrow—can be changed, using the two
CHANGE
VALUE
keys.
The LEDs on these keys indicate whether there is still room for change. That
is, when the upper limit of a parameter’s range is reached, the LED on the “up”
key no longer lights up, indicating that the present value cannot be increased;
when the lower limit is reached, the LED on the “down” key no longer lights up.
The
MORE
INFO
key, when used in the Program mode, displays a bar graph
along with the minimum and maximum values possible for the selected param-
eter. Parameters can be changed either from the main Program Menu or after
the
MORE
INFO
key has been pressed and the additional information is being
displayed (see example below).
