2.1
Intended use
The leak detector LAG-14 is a leak detector for liquid-based systems
as per EN 13160-1, class II (EN 13160-3).
The LAG-14 ER leak detector may only be used to monitor double-
walled containers (tanks) as per chapter 3.1, page 10 containing leak
detection fluid in the interstitial space and used for the aboveground
storage of:
•
Water-polluting liquids
•
Flammable liquids with a flash point of > or
≤
55 °C.
Since July 2003, the LAG-14 ER leak detector may only be used for
replacement deliveries for underground, double-walled tanks as a re-
sult of the reclassification of water-polluting liquids in Germany.
Leaks in the container (tank) are detected and signalled when the
level of the leak detection fluid falls.
Only black containers may be installed in hazardous areas (Ex).
Any use other than the application explicitly permitted in this instruc-
tion manual is not permitted.
2.2
Predictable incorrect application
The
control unit
must never be used in the following cases:
•
Hazardous area (Ex)
If the product is operated in hazardous areas, sparks may cause
deflagrations, fires or explosions.
The intrinsically safe circuit and the corresponding probe may be op-
erated in hazardous areas (EX), zone 0, zone 1 and zone 2.
White containers must not be installed in hazardous areas (Ex).
