ELECTRICAL POTENTIAL:Always switch off the power supply and make sure that it cannot beswitched on again inadvertently before carrying out any installation,maintenance or repair work.

INTENDED USE IN POTENTIALLY EXPLOSIVE ATMOSPHERESThe specialised company must have additional knowledge of fire and explosion protection. If it cannot be excluded that a dangerous, potentially explosive atmosphere can form, the necessary protective measures according to the German Ordinance on Industrial Safety and Health (BetrSichV) must be taken. There is an obligation to assess the probability of a potentially explosive atmosphere, the presence of ignition sources and the potential effects of an explosion and, based on this assessment, to split the potentially explosive atmosphere into zones and take appropriate actions.

The intrinsically safe leak detector type LAG 2000 complies with the requirements for devices and protective systems intended for use in potentially explosive atmospheres according to Directive 94/9/EC. Other technical and organisational measures according to Section 6 and Appendix 4 of the German Ordinance on Industrial Safety and Health (BetrSichV) must be taken.Parts of the LAG 2000 may be installed in potentially explosive atmospheresPart Design Ex protection Ignition protection type

DESIGN AND INSTALLATION DIAGRAMAt the end of this assembly and operating manual you will find an installation diagram (Figure 12) showing the basic structure of a leak detector system with the LAG 2000.How the LAG 2000 leak detector system works.The monitoring space of the tanks contains leak detector liquid that is filled up to the inspection glass of the LDL tank (see Figure 2). When the tips of the sensor unit are submerged in the leak detector liquid, the electrical circuit between the two electrodes of the sensor unit is closed.If the tank has a leak, the leak detector liquid flows out. The tips of the sensor unit are no longer submerged, the electric circuit is interrupted and the display unit shows an acoustic and visual alarm.

Type LAG 2000 A with relay output:The relay for an additional alarm is connected.

Scope of delivery of the LAG 2000:The LAG 2000 is delivered with the following parts:• Display unit • LDL tank with sensor unit and sensor cable • Assembly and operating manual

INSTRUCTIONSBefore assembling, check that the leak detector is complete and has not suffered any damage during transport.For the leak detector to function as intended it must be installed professionally in compliance with the technical instructions applicable to the planning, construction and operation of theentire system.Only companies that are specialised in terms of Section 19 I of the German Water ManagementLaw (WHG) may install, maintain or clean the leak detector. This does not apply if the systemis excluded from this obligation to be installed by a specialised company according to national regulations.Before starting the installation process, observe the following in addition to theINFORMATION ON SAFETY AND USE:

Leak detector liquid: Generally, leak detector liquids are ethylene or propylene glycol-based liquids. They are mixed with water in a specified ratio. The mixture must be adjusted so that it cannot freeze. Leak detector liquids may not enter into a dangerous chemical reaction with the materials that they come into contact with and are therefore especially conditioned for their intended use.

In Germany, only approved leak detector liquids may be used, such as those approved by theFederal Institute for Materials Research and Testing (BAM) (see Page 28).Some tanks may be filled with leak detector liquids in the factory (notice on type label).In Germany, leak detector liquids may be replaced or mixed only if this is permittedaccording to an expert assessment.Observe the instructions provided by the manufacturer of the leak detector liquid.

Leak detector liquid tank – LDL tank

The monitoring space contains a specified volume of leak detector liquid (see type label on the tank ). The larger this volume is, the larger the overall usable volume of all LDL tanks

of the leak detector system must be.The usable volume Va is 50% of the volume between the level of the liquid directly before an alarm is triggered and the top of the LDL tank.The usable volume is Va = 4.5 L.An inspection glass is used to check the level of the liquid.

The LDL tank has a ventilation opening.An LDL tank may be connected only with one tank. Deviating from this, in the case of larger tanks several LDL tanks may be connected in series at the same height.Figure 3: Example ofabove-ground tank withLDL tank and additionalLDL tank

Figure 2: View of LDL tank with sensor unit

Assembly and operating manual Version 11.2012Page 8 of 25

Replacing leak detectors on systems that were installed before 31 December 2002:If more than 1 tank is monitored with one/several LDL tanks or one display unit, no upgrade is required.Several tanks may be monitored with several LDL tanks connected in series at thesame height and with just one display unit if this conforms with the approval requirements.A distinction is made between the following 2 tank storagescenarios to determine the number of LDL tanks required :

Scenario 1: Above-ground tank and underground tank with earth coverage < 30 cm 4)

The usable volume of an LDL tank must be at least 1 L per 35 L leak detector liquid in the monitoring space .One LDL tank is sufficient for 157.5 L monitoring volume. That corresponds to tanks with a storage volume of up to 20,000 L.The number of additional LDL tanks can be determined from the volume of the leak detector liquid in the monitoring space shown in Table 2.Table 2:

The usable volume of an LDL tank must be at least 1 L per 100 L leak detector liquid in the monitoring space.One LDL tank is sufficient for 450 L monitoring volume. That corresponds to tanks with a storage volume of up to 60,000 L.The number of additional LDL tanks can be determined from the volume of the leak detector liquid in the monitoring space shown in Table 3.4) In Germany, underground tanks only within the scope of replacing leak detectors

Connection line between LDL tank and monitoring space of the fuel tank

Is the inlet of the leak detector system.If possible, the inlet and outlet must be attached to the end points of the leak detectorsystem to ensure an adequate flow of leak detector liquid.Do not use any pipes or fittings that are zinc-plated on the inside, as zinc reacts with the leak detector liquid.Pipes and fittings must be protected against corrosion on the outside.The inside diameter of the connection line

Assembly and operating manual Version 11.2012Page 9 of 25

Do not install any constrictions or shut-off fittings in the connection line. Constrictions are possible at the connections.With copper pipes, an isolation part must be installed to prevent contact corrosion.Hoses may only be used where LDL tanks are installed on the domes of underground tanks, or as a short visual section in the connection line.The connection line must not be the sole support for the LDL tank.The connection line must rise continuously from the fuel tank to the LDL tank.

For connection lines in potentially explosive atmospheres, according toDIN EN 131260-3, electrical surface resistance must be < 1 x 109 .This requirement does not apply to the LAG 2000 if the outer diameter of

The isolation part for copper pipes must be equipped with an isolatingspark gap.In potentially explosive atmospheres use only isolation parts and isolatingspark gaps that are certified according to Directive 94/9/EC.

Check valve of the monitoring spaceIs the outlet of the leak detector system.To check the function of the leak detector , the leak detector liquid is drained viaa check valve.The check valve must be dimensioned for a flow of > 0.5 L/min. leak detector liquid , e.g. ½" ball valve.

Display unit

The display unit has a signbut must be installed outside the ex protection zone.

Installation in a dry room that is easily accessible and entered often.Installation at eye height on a smooth, vertical wall.Must not be reached by water or spray water.

If it is installed outdoors, the display unit must be installedin a protective housing with protection type IP 65 and

an external alarm (e.g. "SmartBox 5" GOK Art. No. 28 500 00,rotating light, siren, etc.) must be connected via the relayoutput as an additional alarm.

Relay output for additional alarm "B":• For the values of the potential free relay contact, refer to the TECHNICAL DATA.• Terminal for additional "alarm": In alarm status terminals 2 and 3 are open and

Sensor unit with sensor cable

In potentially explosive atmospheres, install only the intrinsically safe model of the sensor unit.The lid of the sensor unit may be cleaned only when there is no potentially explosive atmosphere.

In a fixed installation the sensor cable must be configured as an intrinsically safe circuit separated from other electric circuits.Do not place the sensor cable parallel to high voltage cables, as there is a risk of extraneous radiation.Protect the sensor cable against damage, installation inside a metal tube is recommended.Do not shorten the sensor cable.Install the sensor cable so that the sensor unit can be dismantled easilyafter it has been installed.

If non-flammable liquids are stored in divided storage tanks together with flammable, highly flammable or extremely flammable liquids, the requirements for storing flammable, highly flammable and extremely flammable liquids apply.If other substances hazardous to water are stored, the relevant statutory and technical requirements must be observed.

5) The LDL tank must not project into the clear opening of the dome; therefore attach it in a niche.6) See installation instructions for the connection line between the LDL tank and the monitoring space of the fuel tank7) Channels from connection lines that come out of the dome must be protected against

the infiltration of flammable, highly flammable and extremely flammable substances and their vapours.

Installation location for the LDL tank:According to DIN EN 13160-3, the LDL tank must be positioned so that

• the hydrostatic pressure of the leak detector liquid at the lowest point of the tank is at least 30 mbar (= 3 kPa) higher than the maximum pressure of the storage medium at the lowest point of the tank (including working pressures) and also the maximum pressure of the groundwater at the lowest point of the tankand

• the pressure in the monitoring space does not exceed the nominal pressure of the monitoring space.

Remark 1: Here, the nominal pressure PN corresponds to the maximum permissible pressure ps
