Pedestrian only installations
Where the sole reason for an installation is to form a portable
pedestrian crossing, i.e. a single vehicle phase serving only the
crossing, you are recommended to use the
PEDESTRIAN ONLY
feature of the Evo controller.
This setting maximises traffic efficiency by resting the vehicle
phase at green whenever there are no pedestrian demands
(normal vehicle operation is to keep all signals at red during quiet
periods).
IMPORTANT: The
PEDESTRIAN ONLY
option can only be used
when all vehicle phases are running the same signals; such
as a single road (or dual carriageway) where all signals
operate in the same manner. Layouts where opposing traffic
streams would cross, such as shuttle working, crossroads,
etc. must NOT be used with the
PEDESTRIAN ONLY
option.
To use Pedestrian only mode
1
Position the vehicle and pedestrian signal heads in
accordance with Highways Agency regulations and set
the slave controllers on each head in the usual manner, as
shown on page 6 and page 7.
2
On the master controller, press
PEDESTRIAN ONLY
,
the adjacent indicator will illuminate.
3
Enable all of the phases that will be used and set
the master controller as shown on the previous
four pages, with the following restrictions:
• Use the Phase 1 controls to set details for all phases.
• Use only the or modes; it is not possible to use the
‘Two opposed heads’ mode (
) in
PEDESTRIAN ONLY
installations.
• It is possible to use the
LINK
buttons to join vehicle
phases in
PEDESTRIAN ONLY
mode, however, all linked
signal heads MUST face in the same direction.
4
Press
RUN
to begin. Operation will start as follows:
• All pedestrian crossings will show red.
• After seven seconds, the vehicle signal heads will go to
green.
• Shortly afterwards, a single pedestrian crossing cycle will
occur (i.e. vehicles to red, pedestrians to green, etc.).
• The system will now rest at ‘vehicles on green’ until a
pedestrian demand is received.
Linking phases
Evo controllers allow you to optionally join phases 1 and 2 as
well as (separately) phases 3 and 4 to suit road layouts. When
phases are linked, all signal heads associated with both of the
phases will act together in the same manner. The extra signal
heads can be made to work in opposing directions (as shown in
example 6 on page 32) or in the same direction (as shown in
example 9 on page 35).
IMPORTANT: It is possible to use the
LINK
buttons to join
vehicle phases when using
PEDESTRIAN ONLY
mode, however,
all linked signal heads MUST face in the same direction. This
ensures that the signal failure modes are handled correctly.
To link phases
1
Switch on the master controller, as shown on page
2
On the master controller, press the
LINK
button
that is located just below the two phases that you
need to join. The indicator next to the button will
illuminate.
3
Choose the required settings for the linked phases, as shown
on the previous three pages, using the controls as follows:
• Use the Phase 1 controls to set the Phase 1 + 2 pair.
• Use the Phase 3 controls to set the Phase 3 + 4 pair.
