Figure 4-60: Settings page with numeric keypad
The current setting displays. A flashing cursor line marks the insertion point, initially positioned after the last character of
the setting. The setting range displays under the text.
Press the
<-- Move Cursor and Move Cursor --> Tab pushbuttons to move the insertion point. Place it after the 1.
Press the Backspace Tab pushbutton to remove the character to the left of the cursor, in this case the 1.
Using the arrow keys, enter another time, for example 4 for four seconds. These Up, Down, Left, and Right pushbuttons
move the keypad key selector. Pressing the
ENTER pushbutton with the - key selected inverts the sign. Pressing the ENTER
pushbutton with the decimal point selected enters that character at the insertion point. Push ENTER now to accept the 4.
Press the Save Tab pushbutton, which does a range check on the value, saves the setting when valid, closes the page, and
displays the previous page.
When a setting is not saved due to an invalid value, a message flashes, for example being out of range. In cases where the
relay needs to be restarted for settings to take effect, the flash message advises.
Setting entry can be cancelled without impact on the original value by pressing the
ESCAPE or Home pushbutton.
Alphanumeric text
Settings that accept alphanumeric values display a keyboard. An example is text for when a pushbutton is on.
The
&123 key toggles between text and numbers.
The shift key (up arrow on keyboard) is green upon activation, while the keyboard letters switch to upper case.
The globe key (shown greyed-out) toggles the keyboard language between English and another display language selected,
for example between English and French.
