Page 10: Application Area
5. Function The LAG-14 ER leak detector monitors the interstitial space of dou- ble-walled tanks filled with leak detection fluid. In the case of a leak in the inner or outer wall of the container (tank), above or below the levels of the stored liquid or the ground water, the leak detection fluid escapes. - Page 11 The green pilot lamp lights up as soon as the leak detector is sup- plied with mains voltage. The Test button allows you to simulate an alarm condition in order to perform a function test. LAG-14 ER...

Page 12: Operating Modes
Product description Operating modes Eco: The LAG-14 ER leak detector is equipped with an output relay to transmit the alarm signal to additional external devices. If no error condition is present, the relay is de-energised; in case of an alarm, the relay is energised. - Page 13 7 Stored liquid, compatible with leak detection fluids 4 All ducts gastight in protective 8 Transparent piece, sealed pipe installation No more than two black LAG containers with probes may be con- nected in series to one control unit.

Mounting and commissioning Calculation fundamentals LAG-14 ER at underground container (tank) The effective capacity of the black LAG container is limited by the liq- uid level screw in the centre of the container; it amounts to 4.5 litres. For underground containers (tanks), 1 litre of leak detection fluid is required in the black LAG container per 100 litres of interstitial space volume. - Page 18 20,000 litres. Together with additional containers with an effective capacity of 4.5 litres each, the LAG-14 ER leak detector can also be used for tanks with a greater interstitial space volume. The additional containers are connected to each other and to the black LAG container by means of EPDM hoses.
