the value will automatically continue to be decreased at gradually faster and
faster rates until the DEC key is released or the parameter’s minimum allowed
value is reached. When the lower two digits display a 00, pressing the DEC
(decrease key) will cause the lower two digits to display a 99 and the hundreds
digit will have been decreased by 1.
INC and DEC Keys Together
In PARAMETER EDIT MODE, the INC and DEC keys are used together to view
the value of the upper two digits of a 4-digit number.
Press and hold both INC and DEC simultaneously to view the value of a 4-digit
number’s upper two digits. Note that the left digit’s decimal point is turned on to
indicate that the thousands and the hundreds digits are being displayed.
Release INC and DEC and now the tens and the ones digits are again being
displayed. Note that the right digit’s decimal point is blinking if editing is allowed
or just ON if editing is not allowed.
Note: Not all parameters are 4-digit numbers, in which case the upper digits will
always display 0.0 (zero dot zero).
In PARAMETER SELECT MODE, pressing both the INC and DEC keys at the
same time will cause all LED segments to be turned on. This serves as an LED
test. Release the keys to resume displaying the parameter ID number.
LED Display
The two 7-segment LED’s along with each digit’s corresponding decimal point
are used to display values and indicate the operating mode of the user interface.
When the value being displayed by the two 7-segment LEDs is blinking,
PARAMETER SELECT MODE is active.
When the value displayed is not blinking, the selected parameter’s value is being
displayed and the user interface is in PARAMETER EDIT MODE. The decimal
points further indicate which half of a 4-digit value is being displayed and whether
editing is allowed.
The right digit’s decimal point is used to indicate that the lower 2 digits of a value
(the tens and the ones digits) are being displayed. When the right decimal point
is blinking, it means that the value can be modified using the INC key or the DEC
key. No blinking means that editing is not allowed or is password protected.
The left digit’s decimal point is used to indicate that the upper 2 digits of a value
(the thousands and the hundreds digits) are being displayed. The upper 2 digits
are always view only so the right decimal point does not blink. Changes to the
upper digits occur when a parameter’s lower digits overflow or underflow during
editing.
An overflow occurs when the value 99 is displayed and the INC key is pressed
(assuming this is not the parameter’s maximum value). This will cause the
displayed value to become 00 while the non-displayed value in the parameter’s
upper 2 digits will be increased by one. You can verify this by pressing both INC
and DEC at the same time to view the new value in the upper digits. For
example: If the full 4-digit value of the parameter you are editing is currently
1099, then after pressing the INC key the parameter’s new value will be 1100.
