Introduction
Welcome
THE Evo series from Pike Signals delivers a breakthrough
in combined vehicle and pedestrian phase control within
portable systems. Drawing upon our long history within vehicle
control dating back to 1932 and particularly our pioneering work
with high-reliability radio-linked computerised systems, the Evo
series is so named because it represents a natural, yet hard
fought evolution to be the best. The best for reliability, the best for
flexibility and the best for safety.
Evo series controllers provide great flexibility, adherence to four
Highways Agency specifications (TR 2502B, TR2503B, TR 2537A
and TR 2538A) and a compact size that allows their use in most
Pike Signals housings.
The Evo series is centred around a range of controllers, which
can support up to nine vehicle phases and can operate as
master or slave. This means that with a fleet of Evo controllers
you will be able to configure the equipment in any order,
maximising utilisation.
The Evo series provides vehicle control, vehicle control with
pedestrian facilities and pedestrian only control. Using the PT5
controller as a Master provides up to five vehicle phases and a
pedestrian facility with up to four crossing points.
To ensure that no job is too large for the Evo series, the PT4
expansion controller connects directly to the PT5 and raises the
maximum capabilities of the system to nine vehicle phases and a
further four pedestrian crossing points.
Important
This system should be installed and operated only by fully
trained and experienced personnel. The junction layout
examples given in this document are for guidance only.
Always consult your supervisor if you are in any doubt
about correct procedures or if you are concerned about
safety. Equipment must only be repaired by Pike Signals
Ltd or authorised repair agents.
Caution
RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN
INCORRECT TYPE.
DISPOSE OF USED BATTERIES ACCORDING TO THE
INSTRUCTIONS.
Further important details about battery disconnection,
handling and disposal can be found in the Operator’s
guide for the signal unit within which the controller is
installed.

pleaseusethe‘Pedestrianonly’setupshownon page 12.
The green crossing time is fixed at seven seconds
for almost all installations. However, there are
special circumstances where this time may need
to be adjusted. The pedestrian MAX GREEN control
allows this to be done on Evo control panels that
have been suitably adjusted. This feature is not
available on standard Evo controllers.

11
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
1Before starting operation (as described
left), press the PEDESTRIAN ONLY/
LIGHTS OFF button until the LIGHTS OFF
indicator illuminates.
2Proceed 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.
3When 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,

...then you should be ready to start operation using the master
controller.
To start operation
aOn the master controller, press the
blue button to choose the appropriate
operation mode. For normal operation,
this should be set to VEHICLE.
bPress 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

enabled vehicle phases until the final one.
• Thenalvehiclephasewillwaitforthelongestallred

• 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.

12
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
1Position 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.
2On 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

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.
4Press RUN to begin. Operation will start as follows:
• Allpedestriancrossingswillshowred.
• Aftersevenseconds,thevehiclesignalheadswillgoto

• 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
1Switch on the master controller, as shown on page
8.
2On 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.
3Choose 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.

Radio channels
Evo controllers that show the MULTI logo on
their front panels offer a greatly increased
number of radio communication channels (1
to 17). This compares with the first generation (Standard) Evo
controllers, which provide channels 1 and 2.
When mixing Multi-channel and standard controllers
If all of your Evo controllers are the MULTI type, then you can use
any of the available 17 channels:
However, if your installation contains any standard Evo controllers
(those that do not have the MULTI logo) then you must choose
either channel 1or channel 2for all units.
All controllers are MULTI,
so any channel between
1and 17 can be used.
If you choose channels 3to 17 then the standard controller(s) will
not be found and the installation will not run.
IMPORTANT: Obviously, you need to ensure that all controllers
within a set are configured to use the same radio channel.
One or more controllers are
Standard (non-MULTI), so only
channels 1or 2can be used.
Using the scan option
1Press POWER to switch on. The text display will show Radio
Channel xx, where xx is the last channel used.
2Press to advance to channel 17 and then press once more
to show Radio Chan. SCAN. Press SELECT.
Note: The controller must be in Master mode to access the
Scan function.
The controller will now scan the radio channels. After roughly
20 seconds, the text display will show the first available
clear radio channel that was detected during the scanning
process.
3Press SELECT to choose the recommended channel, or
manually choose a different channel.
4Continue with the usual configuration steps. Don’t forget to
manually select the same radio channel on all of the other
Evo controllers within the set.
Discovering the radio channel during operation
When the system is running, you can check which radio channel
is being used as follows:
1During normal operation, on the master controller, press the
SELECT button. The text display will show the current battery
charge.
2Press the button to show the radio channel:
Radio Channel 01
3Press the SELECT button to return to the normal display (or
wait for 12 seconds and the text display will automatically
return).

Transmitter power
Evo controllers that show the MULTI logo on
their front panels provide an option, when
they are first switched on, to change the
transmitter power:
Radio Tx Power 3
The standard power level is 3and for most installations this
should not be changed; simply press SELECT during startup to
choose the standard option.
Reducing transmitter power to avoid interference
Reducing transmitter power may be a useful option when two (or
more) separate Evo installations are placed near to each other
and you begin to experience communication issues.
IMPORTANT: You should always try to solve interference issues
by changing the radio channels first before attempting to reduce
transmitter power. If the Evo controllers in set are all MULTI units,
you have the choice of 17 different channels to switch them all
to; if not, you have a choice of 2 channels. See page 13 for
details.
If changing radio channels does not solve the problem, then you
could consider reducing the Tx power in one or more units that
are in closest proximity between the affected sets.
•One or more controllers
in an Evo installation
were affected by a
neighbouring
installation...
•... so the nearest Evo controller
in the second set has its Tx power
reduced so that it does not reach
the closest unit(s) in the first set.
In reducing Tx power, care must
be taken that the unit with reduced
power can still reach its own
master (or if it is the master, that it
can reach ALL of its slaves.
Note: When reducing power in a controller, you must ensure
that its transmissions are sufficiently strong to still reach its own
master; or if it is the master, that it can reach ALL of its slaves.
It is not necessary to change the Tx power level in all Evo units
within a set. A change in Tx power affects only the transmission
of a controller, it has no effect of the reception of signals by that
controller.
As a rough guide, the line of sight transmission distances (when
there are no external sources of interference) are as follows:
Tx power level Power mode Approx.Tx distance
3 and 2 Standard 300 metres (984 feet)
1 and 0 Low 100 metres (328 feet)
To reduce power on an Evo controller
1Switch on the controller in the usual manner.
2Select the radio channel and press SELECT. The display will
now show: Radio Tx Power 3
3Use the or buttons to change the Tx radio power value
and press SELECT.
4Continue with your configuration in the usual manner.
Note: If the controller is switched off and back on, the Tx
power level will be offered at the normal setting of 3.

Operation
Making adjustments
When the system is running, continue to monitor the build up of
traffic on each approach. If regular patterns of significant traffic
queues are emerging on particular approaches, consider making
careful adjustments to alleviate the problem.
Timing adjustments can be made to a phase at any time. The
effects of timing changes will be incorporated during the next full
cycle of operation for each phase.
Note
Introduce timing changes in small steps and one at a time.
Observe the results before making any further changes.
Slow moving vehicles not clearing the works
If there are large numbers of slow moving vehicles which have
difficulty in clearing the works before the signals have changed,
increase the ALL RED settings for the affected approach(es) in
small steps.
1Ensure that the ALL RED indicator is on.
If it is not, press the MAX GRN ALL RED
button located in the centre of the panel.
2Press the phase timing button for the
phase that needs to be adjusted to
increase the ALL RED time.
3Allow several full vehicle cycles to occur and observe the
changes to traffic behaviour.
4Repeat if necessary.
Vehicles taking more than one green period
to clear the works
If substantial queues begin to form and vehicles regularly take
more than one green period to get through the works, increase
the MAXIMUM GREEN settings for the affected approach(es) in
small steps.
1Ensure that the MAX GRN indicator is on.
If it is not, press the MAX GRN ALL RED button
located in the centre of the panel.
2Press the phase timing button for the
phase that needs to be adjusted to
increase the MAX GRN time.
3Allow several full vehicle cycles to occur and observe the
changes to traffic behaviour.
4Repeat if necessary.

16
Operation modes
The blue mode switch determines how the system operates.
MANUAL
Phases respond to the control panel
DEMAND buttons - the microwave vehicle
detectors of the heads are ignored. In
this mode, the ALL RED time settings
for each phase are used, the minimum
green time is set at 12 seconds and the
maximum green time is determined by the
operator’s actions. Note: It is important
to set the correct ALL RED time for each
phase in order to prevent green signals
being given too soon on opposing
phases.
FIXED TIME
All enabled phases
use only their
configured timings
- the microwave
vehicle detectors
of the heads are
ignored. This is an
inefficient mode
of operation as it
does not adapt to
the prevailing traffic
conditions.
HOLD ALL RED
All signal heads
are forced to red
and held until the
mode is changed.
VEHICLE
All enabled phases
use their configured
timings and respond
to the microwave
vehicle detectors on
each signal head. This
is the most efficient
mode of operation
and should be used in
most situations unless
there are special
circumstances.
Press the

Reserved for future use.
Communication failures
The Evo system continually monitors itself to check for any type
of failure so that it can take appropriate action:
After a temporary communications loss
Firstly, all signals will show red for 50 seconds. After that period,
all signals will switch off (unless the master controller is running
in HOLD ALL RED or MANUAL modes, in which case all signals will
remain at red). The text display on the master controller will show
the following:
Coms Recovry 123
Once the counter reaches 600 (10 minutes), the system will go
through an automated restart procedure:

Note: During the ten minute recovery period, it is possible for an
operator to manually restart the whole system.
After a serious communications loss
Following a serious or sustained loss of communication, the
master controller text display will show the following:
Comms Fail
All signals will be instructed to remain off (or at red, if HOLD
ALL RED or MANUAL modes are running). The whole system will
require corrective action by the operator and a manual restart.

Resetting the system
Certain failures within the Evo system require the operator to
cure/acknowledge the failure and reset the system as a whole. In
such cases the system may be held within a special condition or
remain operating in a reduced mode.
To reset the system after an error
1Inspect the master controller indicators to trace the problem,
page 3 provides descriptions.
2If the problem is traced to one or more signal heads, visit
each affected head and check the slave controller(s).
Depending on the fault:
• Ifpossible,rectifytheproblemandresettheslave
controller(s).
• Tryperformingaradiofrequencyscantodetermine
whether a different channel would provide better
operation. See “Using the scan option” on page 13.
or
• Replacethesignalhead(s)/controller(s)andfollowthe
set up instructions shown on pages 6 and 7 to select the
correct phase number(s).
Note: If any slave unit is replaced, the master controller
must be powered off and then on again to force it to look
for all new slaves.
3When all affected heads have been reset, on the master
controller press the RUN button to restart operation. Monitor
the system operation until you are sure that it is working
correctly.
Checking battery charge levels
When the system is operating you can quickly check the exact
battery charge levels for the master and all slaves, from the
master text display.
To check battery charge levels
1During normal operation, on the master controller, press the
SELECT button. The text display will show:
This is the charge level for the master controller’s battery.
2Press the button to advance to the next display:
This is the current radio channel.
3Press the button to advance to the next display:
This is the charge level for the first slave’s battery.
With each successive press of the button, the text display
will show the battery charge levels for each of the slaves.
4When you have finished checking battery levels, press the
SELECT button to return to the normal display.
Note: You can use this procedure to check a slave battery
charge level from the slave controller itself, but it will not be able
to report on any other units. The slave unit will report itself as
‘Local’.
