Appendix 1:
Phase set up examples
This section provides various examples of typical traffic control
scenarios. Each example shows how to set the vehicle phase
and pedestrian modes on the Evo master controller and also
the corresponding phase numbering for each slave signal head
so that they are all addressed correctly and uniquely within the
installation.
Vehicle phase mode buttons
Determine whether each vehicle phase is:
Off, One head per approach ( ), Two heads per approach ( ) or Two opposed heads (
).
This guide uses up to five colours to help differentiate heads belonging to each of the vehicle phases. Where phases are linked, we show
them in the same colour.
LINK button
When pressed and
the LINK indicator is
on, phases 1 and 2
will operate together,
combining their
respective vehicle
heads to show the
same signals.
LINK button
When pressed and
the LINK indicator is
on, phases 3 and 4
will operate together,
combining their
respective vehicle
heads to show the
same signals.
Pedestrian
These two key settings determine
how many crossings are to be used
and whether
Pedestrian Only
Slave signal head identities
Each slave must be given an appropriate identity to match the phase on the master controller that
is determining the signals that it should display. The LCD text in each bubble shows the setting you
should choose on the text screen of each slave controller. The colours shown in these diagrams are
intended to help reinforce the link between the slaves and the various phases of the master.
Master signal head
The signal head that is connected
directly to the master controller will
always be designated as
Veh 1S
or
Ped 1a
. It is shown shaded.
Pedestrian signal heads
The pedestrian heads are all
shown with black outlines as up
to four crossing will all share the
same settings and timings.
This page offers an explanation of the conventions used within
this section. The row of controls shown at the foot of each
example are not exactly as they appear on the controller,
however, they should provide reasonable visual cues as to
how each mode should be set. Of course, other button presses
(timings, etc.) are required to produce a working layout.
