FLASHING GREEN MAN
If an amber is required, the amber can be configured in the signal sequence, and if
a wait indicator is also required, this has to be programmed as a switched sign
phase (see section 6.2.6(b)).
28.2 Alternative Start-Up Sequences
As an alternative to the standard start-up sequence and blackout during Part-time
mode, modifying the lamp sequences may easily provide the following.
(a) Start-up Sequence
FLASHING AMBER for 6 seconds
ALL RED for the length of the starting inter-green plus the amber leaving time
With ROW going first to Stage 1 before completing one cycle.
(b) Part-Time Mode
At the changeover to Part-time mode, following the expiry of all phase
minimum greens, ROW goes to an all-red stage (normally Stage 0) for a
specified time. Flashing amber to all traffic phases and blackout to all
pedestrian and green arrow phases then follows this.
Allocating a dummy phase to the stage provides the specified time in the all-
red stage. The minimum green value of the dummy phase will provide the
time.
At the changeover from Part-time mode the start-up sequence is effective.
28.3 Flashing Signals
The signals on traffic, pedestrian and green arrow phases are normally a continuous
display. If required, displays may be programmed to flash instead, for example:
Traffic phases:
at no ROW: RED
Changing to ROW: RED/AMBER
at ROW: GREEN
Changing to no ROW: FLASHING AMBER
Pedestrian phases:
at no ROW: RED
at ROW: FLASHING GREEN
