2For your safety

2.1 Basic safety information

Read and always observe the safety and warning information in these Operating Instruc­tions.

WARNING: Hazards thro ugh defe ctive devic e

The VICOTEC320 is likely to be unsafe when it:

● Shows visible damage on the outside.

● Has been penetrated by moisture.

● Has been stored or operated under irregular conditions.

When safe operation is no longer possible:

▸ Put the VICOTEC320 out of operation, separate all connectors from the

power supply and secure against unauthorized commissioning.

WARNING: Risk of explosions through explosive sample gas

▸ Do not use the VICOTEC320 to measure explosive, combustible or

flammable gases.

FOR YOUR SAFETY 2

WARNING: Explosion hazard in potentially explosive atmospheres

▸ Do not use the VICOTEC320 in potentially explosive atmospheres.

CAUTION: Eye injuries caused by improper handling of UV or blue light beams
The UV beam of the deuterium lamp or the blue light beam of the LED can
cause serious injuries through direct eye and skin contact. This results in the
following safety measures when working on the switched on device with access
to the light beam exit:

▸ Always wear UV protective goggles (in accordance with standard EN 170)
▸ The UV goggles do not provide protection against injuries caused by blue

light beams, therefore switch the LED off when working.

▸ Use the lamps only when they are perfectly safe. Operation is not allowed

when the lamp, supply lines or operating parts are visibly damaged.

4 Project planning

4.1 Assembly project planning

4.1.1 Arrangement along the tunnel section

The number and distribution of measuring points depends on the ventilation system used.
Single factors are:

● Type of tunnel profile

● Section route

● Ventilation system design

● Number and arrangement of fans

● Regional regulations

Measuring point selection depends primarily on the following criteria:

● A combination of VICOTEC320 with VICOTEC 410 or VISIC100SF is recommended for

optimum measuring results.

● The recommended distance between visibility measurements depends on whether

these are also to be used for smoke detection:
– Without smoke detection: ≤ 400 m
– With smoke detection: ≤ 150 m

● We recommend VISIC50SF for smoke detection.

● An even spread along the tunnel length is recommended for semi and transverse

ventilation, with at least 2 measuring points per ventilation section.

● NO/NO

preferably at the tunnel exit in tunnels with one-way traffic.

● Two-way traffic can still arise in tunnels with one-way traffic. It is therefore recommended

to install at least 3 measuring points for visibility in tunnels with lengthwise ventilation:
one each about 150 m from the entrance and at least one in the middle of the tunnel.

● It is recommended to install additional fog sensors (e.g. VISIC620) near the tunnel

portals when there is a risk that fog can be sucked into the tunnel. Dust particles acting
as additional condensation crystals can strengthen the fog effect in the tunnel sections.
Fog moisture overlays visibility due to dust particles. Fog sensors serve to prevent fog
drifts being sucked into the tunnel. Alternately, visibility can be measured at the tunnel
portals using measuring devices (e.g. VISIC100SF or VICOTEC450) that heat the air
sucked in and therefore evaporate fog moisture.

● When the tunnel roadway curves, ensure that the measuring beam between single

sensors is not interrupted by the tunnel wall, fixtures or vehicles passing each other (see

see “Arrangement with special prerequisites”, page 16).

can be measured every 400 – 1000 m. Position the measuring points

2

4.1.2 Arrangement in cross-section profile

Particle concentration distribution in a tunnel is generally very even across the profile
cross-section during traffic movement. Traffic flows and lengthwise flows through natural
ventilation and the piston effect of vehicle movement in separate tunnel sections for each
direction effect rapid swirling of the air in the tunnel. The turbulence behind vehicles
strengthens this effect.

The height is not critical due to excellent swirling. A fitting height between 2.8 and

4.5 meters is aimed at. The sensors contaminate faster when fitted lower and the
maintenance effort increases when the sensors are fitted higher.

Fig. 4: VICOTEC320 fitting height

Fitting location selection of the respective sensor pairs depends primarily on the following
criteria:

● Mount the sensors at a safe distance from traffic movement (see for example Section 2

of the German “Richtlinie für die Ausstattung und den Betrieb von Straßentunneln
RABT”, version 2006 (Regulations governing equipping and operating road tunnels)).

● Good access for maintenance and checking work must be ensured. Locate the sensors

in a protected recess when possible.

● Do not locate sensors in close vicinity to ventilators or in the fresh air flow from blowout

units so that the measured value records the effective concentration ratios.

● The measuring beam must run lengthwise between sensors and must not be hindered

by fixtures or vehicles passing each other. Fixtures that shine (e.g. emergency exit signs)
should be at least 1 m from the optical axis.

● No reflecting paint should be on the wall between sensors.

● Maintain a distance of 10

● Plan sufficient clearance to be able to flap or remove the enclosure cover.

Measured values of gases are kept constant at first when the light beams are
interrupted. A malfunction message is sent to the evaluation unit when interruptions
last lo nger than two minutes.

Fitting options:

● Both sensors on a wall in a recess (recommended).

● Both sensors on a wall above the side strip; requires safety measures for maintenance

5 INSTALLATION

Not included in scope of delivery:

● Stainless steel assembly consoles for the sensors

5.6 Assembly

Assembly work must only be carried out by skilled persons familiar with the assembly work.

5.6.1 Fitting the assembly consoles

The assembly consoles comprise 3 parts:

Fig. 9: Assembly console

1 Wall holder for wall fitting
2 Angle bracket to fasten the sensor
3Angle bracket screws

Two angle bracket screws fasten the wall holder and the assembly console together. The
angle bracket can be swiveled up to ±7.5° to compensate any assembly unevenness.

Observe the following points during assembly:

▸ Observe local valid safety measures.
▸ Only use high-strength and absolutely non-corrosive fastening material made of

stainless steel because the tunnel atmosphere is highly corrosive.

▸ Ensure there is enough space to remove the tube and device cover.
▸ Keep the length of the measuring section as exact as possible. Record small

deviations in the Assembly protocol.

▸ Mount both assembly consoles at the same height. Height differences in the optical

axis can be compensated later by swiveling the angle bracket.

▸ Align both assembly consoles at the same tilt angle to the tunnel wall. Different tilt

positions to the tunnel profile make the following sensor alignment difficult. Insert
washers under the wall holder when necessary.

Procedure

1 Determine the installation location for the assembly consoles according to the project

planning.

2 Drill the wall holder openings according to the Drilling plan, see see Fig. “Wall holder

assembly drilling plan”, page 21.

3 Insert dowels or wall ties according to the manufacturer's assembly specifications (walls

must be made of at least C20/25 to C25/30 concrete).

5 Click the [Start Span test] button.

>>>

The system performs a zero adjust with the test reflector, followed by a reference
cycle. The current status is shown in the Operating state text field.

>>>

The process takes approx. 10 minutes and is terminated when “Spantest (insert
cuvette)” is displayed.

6 Check the signal strength

▸ Menu: Diagnosis/Sensor values/Spectra/Measurement reflector.

>>>

The maximum intensity for NO should be in the range from 23000 to 28000 and for
NO

in the range from 42000 to 48000.

7 Observe the measured values for the zero point for approx. 5 minutes and determine the

2

average zero point. Use this value as zero point offset for the next steps.
Example: The default values of the test cuvettes must be added to the zero point offset.

The zero point offset can also be negative.

8 Insert cuvette or filter and wait for at least 5 minutes until the measurement has

stabilized.

9 Observe the displayed measured value for approx. 5 minutes and use the average value.

Compare the measured value with the default value of the test cuvette + zero point
offset (= actual default value). If required, calculate the correction factor (span
coefficient) (see “Determination and setting of the span factors”, page 59).

10 Repeat steps 7 to 9 for every test point.
11 Click [Maintenance] and wait until operating state shows “Maintenance remove

cuvette”.

Do not remove test tool beforehand.

12 Remove the test tool.
13 Restart the system:

▸ Menu: Maintenance/Operating mode switch/System reset
▸ Click [Start system reset].

14 Wait for one minute. Reconnect SOPAS ET (switch “Online”).
15 Wait until the reference cycle has completed.
