PRO User Guide

The SV

258

PRO kit consists of two carrying

cases. The main unit is a waterproof carrying

case with internal 17 Ah battery and internal

charging unit supporting powering from exter-

nal DC or solar panel.

The SVAN

958A

Class

1 sound and vibration

level meter is installed inside.

The outdoor charger and vibration accelerom-

eter kit are packed inside the second transpor-

tation case.

The kit includes license for SvanPC++ software

and a basic SvanNET account. Each kit has its

factory calibration certificate and 36 months

warranty card.

What's inside?

From September 2018 the SV

258 PRO can be

used with a new firmware for building vibra-

tion.

The new firmware simplifies setting up the sta-

tion in accordance to international and local

standards such as DIN 4150-3 or BS 7385-2.

The biggest advantage of the new firmware

is the real-time vibration events analysis in the

unit either with FFT or 1/3 octave and direct

comparison to criterion curves on-site.

In practise this means that station can gener-

ate alarms within a couple of seconds.

Dedicated Firmware

Trigger is set to DIN 4150-2, the build-

ing type, marked as Line 2 (L2).

When the trigger condition is met, the

Alarm Lamp will turn on and stay on

for 1 second according to the setting

Hold Time.

When the trigger condition is met, one

SMS and one E-mail will be sent to Re-

cipient: Adam at the time of alarm.

Alarm Interval is set to 1 minute, so

the next SMS or E-mail would be sent

after 1 minute.

Event Duration is set to 4 seconds,

which means that the event will last 4

seconds starting from the trigger.

When the curve selected for a given type of building is used as the event trigger,

the Peak Particle Velocity (PPV) and Dominant Frequency (DF) is compared against

the curve. If the PPV value exceeds the curve limit, the event starts and lasts in

accordance with the Event Duration setting. The Event Duration parameter should

be set accordingly to observed vibration type.

At the Event Start the Alarm Lamp, E-mail Alarm and SMS Alarm are activated. It

is necessary to activate at least one action: Lamp, SMS or E-mail in order to Start

an Event. The option Alarm Interval allows to set up a break-time before next SMS

or E-mail will be sent. The reduction factor works as the curve multiplying factor

and allows the curve to be moved up or down, so the alarm can be started earlier

or be postponed.

Building Vibration Events

Example Event Settings

Reduction Factor is set to multiplying

factor of 0.5 to shift down the L2 curve.

PRO User Guide

At the given example the Event has been started by the PPV of 5.278 mm/s at

33 Hz. The PPV value meets the condition of Reduction Factor that has been set to

0.5 as the value of 5.278 mm/s is at 50% of the L2 curve height at this point (the

L2 at 32.9 Hz is around 10.5 mm/s). The SVAN

958A stores the value that triggered

the Event as the Alarm value that can be displayed in SvanPC++:

According to the Event Duration setting, the Event lasted 4 seconds (Stop at

19:22:09.600). At the Stop point the system analyses the 4 seconds of previous

data to determine the Event maximum PPV in each axis, which in this example is

the value of 8.306 mm/s at 32 Hz at the X axis

DIN

4150-3 Application

258 PRO can be easily configured to measure building vibration in accordance

to DIN 4150-3, both for short-term as well as continuous measurements.

1) Go to Menu then Application and select standard DIN 4150-3. Select one of the

criterion curves for the given building type (L1/L2/L3).

DIN

45669-1 specifies two filters 1-80 Hz and 1-315Hz for vibration measure-

ments in the vicinity of railway traffic routes or blasts.

Once the application is selected then 2 types of DIN 4150-3 results view will be

available on the display. Use Alt+UP / DOWN to switch view:

1) Go to Menu then Events and activate up to 5 events. Select the L2 criterion

curve as the event trigger. You can shift up/down the L2 curve using the reduction

factor (multiply factor).

Event can trigger Alarm Lamp, Email or SMS. It is important to set up the event

duration for the length of observed vibration activity - for example 10s for train

passage. To browse events on the screen use UP/DOWN arrow in DIN 4150-3 view.

Note: When station is exchanging data with SvanNET the Criterion Curve view is

not accessible due to limited computational power of the SVAN 958A instrument.

1) The station is programmed to automatically establish a 3G connection with

SvanNET. It takes up to 5 minutes to connect. The most important parameter of

the connection is the APN (Access Point Name). The default setting for the APN is

"internet".

It is possible that your Internet provider is using a different APN, in which case the

APN must be entered manually, either via the PC software or the SVAN

958A menu

- Remote/Modem Connection.

Access Point Name

1) Insert a normal SIM card into the slot in the modem. The SIM card PIN pro-

tection must be disabled. A click sound indicates that the SIM card is in the right

orientation. If necessary use a tool (e.g. pen) to push the SIM right in.

It is strongly recommended to configure the remote communication before going

on site. Start from opening the SV 258

PRO station. Locate the 3G modem on the

right-hand side of the case.

4) To connect the microphone extension cable start by lining up mark on the plug

and INPUT 1-3 socket, then lock the connector by turning the ring clockwise (only

the ring close to the socket will rotate).

5) Connect the power supply cable to the DC Supply socket in the same way.

258 PRO User Guide

6) To disconnect cables push the connector towards the station and turn it coun-

ter-clockwise. New connectors require more force so using a closed hand is more

effective than using just fingers.

Air pressure compensation valve

Each case monitoring system is equipped with an air pressure compensation valve

that must be closed when station is used outdoors, otherwise the system is not

sealed against moisture ingress. The lower pressure inside the case may cause

difficulty when opening the lid. In such cases the relief valve needs to be turned

slightly counter clockwise before opening the case lid. The valve is located at the

front of the case.

Close the valve before you leave
