5.4 LEDs
The keyboard has 16 LEDs, connected to registers. The value of the registers de-
termines the color and blinking frequency of the LEDs. For further information
we refer to the section LEDs in the manual for the operator terminals and the
configuration tool.
The content of the LED register is to be in consecutive order to make the com-
munication between the operator terminal and keyboard quick and efficient.
Right-click on the X-Key icon in the Peripheral Configuration window and
select Open to display a view of the keyboard. Double-click on a LED to display
the LED configuration window.
There is no separate heart beat LED, but all LEDs together will flash in red if
the communication to the master terminal is broken, i.e. if the X-Key 16 has not
received any information in a couple of seconds.
The dimmer function can be on or off, controlled by a digital signal. All LEDs
will be affected by the dimmer function. See section
5.1 Configuration for
details.
The LEDs are also used to indicate errors. See chapter 7 Error Indication for
further information.
When a new system program is loaded, LED L1 will flash in green. Normally
there is no need to load a new system program.
