Function
Indicate the stage (or combinations of stage for parallel stage
streaming) that the controller has reached when in manual
mode.
While the controller is moving to the stage, the indicator flashes.
When the stage is reached, the indicator stops flashing and
remains illuminated.
Indicate what mode has been selected.
If the mode is unavailable, then the indicator flashes. Note that
during the start-up sequence, the indicator for the selected mode
flashes, since the controller is in start-up mode, which is always
the highest priority. When the start-up is complete, the indicator
for the selected mode normally stops flashing and remains on
steady. If 'Normal' mode is selected, then the controller also
illuminates one of the other mode indicators if the controller is
running that mode, e.g. VA.
Under manual control only, this LED illuminates at the end of the
minimum green period, signifying that a new stage may be
selected by the stage select pushbuttons.
Selection of a stage before the LED is lit is prevented and any
such selection is ignored.
This LED illuminates if a prohibited stage to stage movement is
attempted while under manual control. It remains illuminated
until a permitted move is made.
Illuminates during all modes of control when there is a hurry call
being serviced, or can be configured for an auxiliary function.
Illuminates when there is a mode with a higher priority than
manual mode, such as UTC Control, or can be configured for an
auxiliary function.
These LEDs can be configured to display auxiliary functions
active such as Dim Override.
