4.14.1 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 a particular example.
Button
Function
MANUAL
BUTTON
INDICATORS
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.
MODE SELECT
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.
AWAITING
COMMAND
LED
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.
PROHIBITED
MOVE LED
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.
HURRY CALL
(AUX 4) LED
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.
AUX 1 - AUX 3
LEDs
These LEDs can be configured to display auxiliary functions
active such as Dim Override.
