Performing a test start
With the standard set up procedure, the system does
not come into full operation until you press the
RUN
button. It’s at that point you discover whether all the
slaves are properly responding. In some situations,
particularly where the Evo installation is about to
replace a large set of fixed signals, it is important to
confirm that all units are correctly co-operating before
the fixed signals are switched off. By performing a
test start, the Evo master will begin running as normal,
however, it will inform all heads to not show any
signals.
To initiate a test start
1
Before starting operation (as described
left), press the
PEDESTRIAN ONLY/
LIGHTS OFF
button until the
LIGHTS OFF
indicator illuminates.
2
Proceed with the usual start up, as
described left.
If there are any problems, these will be reported on
the master text display.
If everything is OK, although the lights don’t
sequence and the mimics do not illuminate, you
will see the display timer counting through its
phases.
3
When you are confident that all is OK, either press
the
LIGHTS OFF
button to take the system into
normal start up signal sequence; or press and hold
the
POWER
button to halt the system and switch off
(if actual operation will occur later on).
...Setting the master (cont.) - Starting operation
Once the following stages are complete:
• All heads, signs and cones placed in appropriate locations,
• Vehicle slave controllers set,
• Pedestrian slave controllers set (if used),
• Vehicle phase(s) set on the master,
• Pedestrian crossings set (if used) on the master.
...then you should be ready to start operation using the master
controller.
To start operation
a
On the master controller, press the
blue button to choose the appropriate
operation mode. For normal operation,
this should be set to
VEHICLE
.
b
Press
RUN
.
The various signal heads of the installation
will now start up in an orderly manner:
• All pedestrian crossings will show red.
• The lowest numbered vehicle phase will show amber
and then go to red.
• The next lowest numbered vehicle phase will show
amber and then red. This will continue through all
enabled vehicle phases until the final one.
• The final vehicle phase will wait for the longest all red
time to run and then changes to green.
• Normal operation will commence once the highest
numbered vehicle phase has completed its initial cycle.
The vehicle phase and pedestrian mimics
will show what each of the signal heads are
currently displaying.
Note: When the controller is used as a slave,
regardless of which phase is set, the Phase 5/
Slave mimics are used to show Slave operation.
The vehicle
DEMAND
and pedestrian
WAIT
mimics will show how requests are being
made to the controller by road users and
pedestrians, respectively.
