1. Introduction
1.1. Objectives
The objective of this document is to give technical information about PORTABLE TRAFFIC SIGNALS ST-PS5 and describe steps
to setup and operate the device.
1.2. Scope
This document will describe the design, features, dimensions, technical specifications, setup and operational modes of the ST-
PS5 Portable Traffic Signals. Further information can be acquired on the web site or directly with manufacturers.
1.3. Introduction
The Sphere ST-PS5 Portable Traffic Signals is a modular mobile traffic signal system intended to be applied primarily to shuttle
the control of vehicular traffic at road works or bridge works.
Road works where Portable Traffic Signals are applied have a a section of the carriage-way closed, so the single lane must be
used alternatively by traffic from the opposite directions.
Other than vehicle-actuated alternating one-way traffic, the ST-PS5 can also be used for controlling the T-junction situations,
crossroads traffic and roundabouts, with up to 7 signals operating simultaneuosly in a Daisy Chain operational mode.
The ST-PS5 Portable Traffic Signals are equipped with a directional radar for vehicle-actuated operation, radio communication
with a range of up to 1000 m under ideal conditions and emergency mode for quartz control when the radio communication
is faulty.

2.3.4. TIME ADJUSTMENT – Add Seconds 1-9
If there is a strict need for the duration of CLEARANCE TIME/ALL-RED to be set between 11 and 189 seconds, you can use the
ADD SECONDS 1-9 option.
E.g. there is a need for the duration of CLEARANCE TIME/ALL-RED to be set at 75 seconds instead of 70 or 80 as predefined on
the operator interface:
1. Move the CLEARANCE TIME/ALL-RED knob to the position ADD SECONDS 1-9
2. On the amber light, the countdown timer will commence counting from 1 to 9 where each number represents the
additional second
3. When the desired additional second is displayed (e.g. 5 seconds), move the CLEARANCE TIME/ALL-RED knob
backwards. This procedure memorizes and adds the additional 5 seconds to each entered duration of CLEARANCE
TIME/ALL-RED phase
4. Move the CLEARANCE TIME/ALL RED knob to the position 70, and the 5 seconds of additional time will be
automatically added, thus resulting in 75 seconds of clearance time
If you want to remove the additional seconds feature, you can either move the CLEARANCE TIME/ALL-RED knob to the
position ADD SECONDS 1-9 and then immediately move it backwards before the countdown from 1-9 commences, or simply
RESET the portable traffic signals by reconnecting the battery clamp to the battery.

2.3.5. TIME ADJUSTMENT – Green
The GREEN rotary knob is used to set the duration of GREEN phase after which the signal head will turn to 3 seconds AMBER,
and then RED (in the EU version, otherwise according to the corresponding national regulations).
You can set the duration of GREEN time by rotating the corresponding knob to the desired setting.
 In RADAR MODE, the GREEN phase runs as maximum green phase, depending on the volume of traffic.
The minimum green phase always runs and is factory set at 12 seconds and is non-adjustable.
The green phase is extended by the oncoming vehicles that trigger the radar detectors up to the maximum green
phase which is user user-adjustable and can be set from 20-240 seconds.
If no more vehicles are registered between the minimum and maximum green phase, the current green phase is
ended.
 In FIXED TIME, the GREEN phase runs according to the fixed setting regardless of the volume of traffic.
The duration of each GREEN phase is the same, and is user-adjustable ranging from 20-240 seconds.

2.3.6. TIME ADJUSTMENT – Channel Selection
You can use the CHANNEL SELECTION feature if you have more than one set of Portable Traffic Signals close to each other and
you want them to operate independently from each other in radio operational mode.
You can choose between channels ranging from 1 to 16, where channel No.1 has a frequency of 433.00 MHz, up to a channel
No.16, which has a frequency of 434.60 MHz.
E.g. to program the channel No. 12 on the portable traffic signals:
1. Move the GREEN knob to the position CHANNEL SELECTION
2. On the amber light, the countdown timer will commence counting from 1 to 16 where each number represents one
of the available channels for selection
3. When the desired channel is displayed (e.g. 12), move the green knob to green time setting.
This procedure permanently stores the channel number into the memory of the portable traffic signals.
If you want to program another channel into the portable traffic signals, repeat the above procedure, with the new channel
number.

4.1. Radio Operational Mode (The Default Operational Mode)
Sphere portable traffic signals are fitted with a 433.05-434.79MHz antenna that provides reliable wireless radio
communication between portable traffic signal units. For the best results, the portable traffic signal units should be
positioned line-of-sight to each other. A maximum range of up to 1 kilometer between the Master and Slave(s) can be
achieved in ideal conditions.
Portable traffic signals must be set on the same channel for a wireless communication to be established between Master and
Slave(s).
When using the Sphere Portable Traffic Signals in a Radio Operational Mode, the MASTER unit controls the SLAVE unit(s) via
Radio Linked Communication, meaning that setting the operational modes or time phases is done exclusively on the MASTER
unit.
MASTER --- The Master controller determines the overall operation of the system according to the selected configuration,
mode and time settings. There must be only one Master controller in the system.
SLAVE - Slaves are primary controllers which signal as instructed by the Master controller. The operator can't control the
signal timings on Slave units in a radio operational mode.
The operator sets the timings of ALL RED/CLEARANCE TIME and GREEN exclusively on the MASTER unit, which when set, will
result in the immediate synchronization of all units connected via radio link (1 Master and 1 or more Slaves).
You can use 1 Master unit with:
 1 Slave unit in a FIXED TIME operational mode
 1 Slave unit in a 2-Way RADAR operational mode
 Up to 6 Slaves in a DAISY CHAIN operational mode.
IN A RADIO OPERATIONAL MODE, SETTING UP THE
OPERATIONAL MODES (fixed time, 2-way radar,
manual green…) OR TIME PHASES (clearance
time/all-red, green) IS DONE EXCLUSIVELY ON THE
MASTER UNIT!
