Changing Backlight Delay
The display of the operator interface is only readable with the aid of a backlight.
In order to preserve the life of the lamp that provides this, the backlighting is
automatically shut off after a duration of inactivity on the keypad. The backlight
is restored by pressing any key. The pressed key will not have any other affect on
the operator interface when pressed with the backlight off.
To change the duration of the delay, press the [F2 key. The current backlight delay
will be shown in reverse video (
Figure 82 ). The value can be adjusted from 0...60
min. A value of zero (0) will disable the “delay, keeping the light on indefinitely.
Press the [cursor up] or [cursor down] keys to change the value by a resolution of
1 minute. Press the [cursor left] and [cursor right] keys to change the value by a
resolution of 10 minutes. To abort the change, press the [backspace] key and the
setting will return to its original value. To accept the change press the [enter] key.
The backlight delay has been saved.
The setting may also be aborted by pressing any of the assigned function keys
(other than F1). The function associated with that key will be executed.
