3.17.1 Manual Panel LEDs
The LEDs on the Manual Panel are used to identify which stage is active and to display status.
Several versions of the Manual Panel are available and some of the indicators in the following
summary may not be present in all variants.
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.
HIGHER PRIORITY
(AUX 5) LED
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.
