The VISY-X system (Volume Information SYstem) provides highly precise and continuous level

measurements for all commercially available fuels in up to 16 tanks. Simultaneously the

product temperature and the water level at the bottom of the tank are measured.

The system includes:

•VISY-Command (central unit)

•VISY-Setup (software application) for configuring the VISY-Command

•VISY-Stick (filling-level sensors) for tank gauging in the versions:

VISY-Stick, VISY-Stick Advanced, VISY-Stick Advanced with VISY-Density Module,

VISY-Stick Flex, VISY-Stick LPG (liquefied petroleum gas), …

In addition, following environmental sensors can also be operated with the VISY-X System:

−VISY-Stick Sump for monitoring the manhole or the dispenser sump with the distinc-

tion between product and water

−VISY-Reed Sump for monitoring the manhole or the dispenser sump without a dis-

tinction between liquids

−VISY-Stick Interstitial (with configurable measuring range) for monitoring the inter-

mediate chamber in double-walled tanks

−VISY-Reed Interstitial (with fixed measuring points) for monitoring the intermediate

chamber in double-walled tanks

−VISY-Stick Temp for temperature measurement with up to 31 integrated temperature

sensors depending on the probe length

−VIMS Sensors (VIMS-Tank , VIMS-Product Pipe, VIMS-Delivery Pipe) for monitoring

the intermediate chamber in double-walled tanks, filling lines and product lines from

our system partner SBG GmbH, see chapter 1.1

−COMS (Continuous Oil separator Monitoring System) with VISY-Stick Oil separa-

tor and VISY-Sludge probes for monitoring the oil and sludge layer in oil separators,

The complete VISY-X system should only be installed by trained service engineers.

Page 3/28 Introduction

1.3 Safety instructions

The VISY-X system is optimised for use in petrol stations and is compatible with all commer-

cially available fuels. It serves to measure and evaluate the filling levels in tanks. The system

must be used exclusively for this purpose. Observe and follow all product safety notes and

operating instructions. The manufacturer accepts no liability for any form of damage resulting

from improper use.

The level and environmental sensors and the VISY-Command central unit have been devel-

oped, manufactured and tested in accordance with the latest good engineering practices and

generally accepted safety standards. Nevertheless, hazards may arise from their use.

The following safety precautions must be observed in order to reduce the risk of injury, electric

shocks, fire or damage to the equipment:

•Opening or removing the housing cover from the VISY-Command could result in a

risk of electric shock.

•Do not change or modify the system or add any equipment without the prior consent

of the manufacturer.

•Only use original parts. These comply with the technical requirements specified by the

manufacturer.

•The installation, operation and servicing of the sensors and the VISY-Command must

solely be carried out by expert personnel.

•Operators, installers and service technicians must observe all applicable safety regula-

tions. This also applies to any local safety and accident prevention regulations which

are not stated in this manual.

•The VISY-Command central unit is only suitable for wall mounting inside buildings

and must not be installed in potentially explosive areas.

•The isolating amplifiers type VP-… respectively VISY-RFR, and the interface type VI-…

included in the VISY-Command central unit must always be undamaged and clean.

•During normal operation, the casing cover of the VISY-Command central unit must

remain closed.

•The product may be powered only via the permissible auxiliary power supply.

The safety instructions in this manual are marked as follows:

If these safety instructions are not observed, it may result in the risk of accident or

damage to the VISY-X system.

Useful tips and information in this manual, you should observe, appear in italics

and are identified by this symbol.

Versions of the VISY-X system Page 4/28

2Versions of the VISY-X system

Two versions of the VISY-X system are available which differ in different data transmission

technology:

(1) The wired version

(2) The wireless version / radio system

2.1 Wired version

In most cases, data is transferred between the sensors and the VISY-Command central unit via

cable. This cable is also in charge of the voltage supply of the sensors. The wired version of the

VISY-X system is the standard version.

2.2 Wireless version / radio system

If no free cable ducts are available at the petrol station, it is possible to instead opt for the

wireless tank gauging system. In this case, the benefit of installing the wireless system is that it

does not entail any excavation work.

In the wireless system, the sensors are connected to a transmitter and powered by a battery.

The radio version of the central unit is equipped with a receiving module.

The radio system consists of the additional components:

•VISY-RFR (radio frequency receiver, receiver installed in VISY-Command … RF)

•VISY-RFT (radio frequency transmitter, transmitter with battery)

The installation procedure for the wireless system is described in the following technical

documentation:

VISY-RF III radio system, art. no. 350272

Page 5/28 VISY-Command

3VISY-Command

The designation of the VISY-Command depends on the number of sensor terminals or the

transmission technology, for example, "VISY-Command 8" with eight sensor terminals or "VISY-

Command RF" as wireless version.

3.1 Design and function

3.1.1 VISY-Command – wired version (standard)

The wired (standard) version of VISY-Command has 2, 4, 8, or 16 sensor terminals.

At each sensor terminal, it is possible to connect up to three different types of FAFNIR sensors

VISY-Stick/Reed (e.g. one VISY-Stick, one VISY-Stick Interstitial and one VISY-Reed Sump).

These three types of sensors can be connected to each other directly at the installation point.

This means that only one cable (4-wire) is required for the connection to the VISY-Command.

In combination with the VIMS sensors from our system partner for leakage control

(SGB GmbH, Siegen), either 2 FAFNIR sensors and 2 SGB sensors or 3 FAFNIR sen-

sors and 1 SGB sensor can be connected to the VISY-Command central unit using

one single cable (4-wire).

Connecting sensors of the same type (e. g. 3 x VISY-Stick or VISY-Stick Interstitial

with VISY-Reed Interstitial) to one sensor terminal is not supported.

The terminal box/cable connector used to extend the connection cables for the

sensors in the manhole chamber must comply with a degree of protection of IP68

for the housing.

The VISY-Command central unit comprises a VI-4 interface and one or two VP… isolating

amplifiers installed in a housing for wall mounting (IP20). One VP… isolating amplifier is

installed in the VISY-Command 2, 4 or 8; two VP-1 isolating amplifiers are installed in the

VISY-Command 16.

The sensors are electrically supplied with power via the VISY-Command. The VISY-Command

receives the measured values, stores this data temporarily and makes the data available to a

higher-level system (e.g. central computer). A serial interface, either an RS-232 or an RS-485,

is used for communication. Various logs are available for transmitting the data to the service

station computers.

The IFSF-LON interface is also available as an option, see the following technical documenta-

tion:

IFSF-LON interface converter, art. no. 207092

VISY-Command Page 6/28

3.1.2 VISY-Command RF – wireless version (radio system)

With the wireless version (RF), each VISY-Stick/Reed sensor is connected to one VISY-RFT

transmitter, which transmits the measured data to VISY-Command RF.

Up to 16 VISY-Stick/Reed sensors can be operated in conjunction with the VISY-Command RF.

Each sensor is electrically powered via a battery in the VISY-RFT transmitter.

The VISY-RFT transmitter must not be operated without an antenna.

If the wireless system is used, it should be noted that reception conditions may

vary with the number of cars or lorries passing through the petrol station. This

can, under certain circumstances, result in long data reception failures in the

VISY-Command. Therefore, the tank data may not always be updated at the set

transmission intervals and delivery data could potentially be lost.

For improved wireless communication, the VISY-Command RF should preferably

be equipped with two external receiving antennas.

The VISY-Command RF comprises an interface VI-4 and a wireless receiver installed in a case to

be mounted on the wall (IP20). The data received from the VISY-Command RF is evaluated,

stored temporarily and made available to a higher-level system (e.g. central computer).

Communication takes place via a serial interface, either the RS-232 or RS-485. Various logs are

available for transmitting the data to the service station computers.

The IFSF-LON interface is also available as an option, see the following technical documenta-

tion:

IFSF-LON interface converter, art. no. 207092

The installation of the wireless system is a complex installation procedure and is described in

detail in the following technical documentation:

VISY-RF III radio system, art. no. 350272

Page 7/28 Installation

4Installation

When installing and operating the VISY-Command central unit, the requirements

of the Explosion Protection Regulations, the Industrial Health and Safety Regula-

tions and the Equipment Safety Regulations as well as generally accepted rules of

engineering and these operating instructions must be observed.

Observe also the local safety and accident prevention regulations, which are not

stated in these operating instructions.

Wiring work may only be performed with the power disconnected.

4.1 Assembly

The VISY-Command central unit must be securely mounted on a wall inside a building.

The VISY-Command central unit is not suitable for outdoor installation.

For mounting the case, the VISY-Command contains the relevant drilling tem-

plate.

4.1.1 Sensor connections

4.1.2 VISY-Command – wired version (standard)

Connect the filling level and environmental sensors to the sensor terminal block on the VP-…

board (see Figure 1 and Figure 2). To feed in the cable, please use the blue cable gland for

intrinsically safe circuits.

The maximum permitted external inductance must not exceed 40 mH and the

maximum permitted capacitance must not exceed 680 nF including the cable (see

data sheet of the used cable).

The connection cable between the sensors and VISY-Command must have the following

characteristics:

•4-core unshielded, oil-resistant cable

•Cable cross-section (4 x 0.5 mm² up to 100 m or 4 x 1.0 mm² up to 200 m)

•Colour blue or marked blue (cable for intrinsically safe power circuits)

•Maximum diameter of 10 mm to fit through the cable glands in the VISY-Command.
