OVERPRESSURE – LEAK DETECTOR DL ..
(1) Once a year to ensure functional and operational safety.
(2) Scope of inspection as per chapter 6.4
(3) Also check compliance with the conditions in chapter 4.5 and 6.2.
6.3 Intended
use
•
Groups of interstitial space
only for underground
interstitial spaces.
•
Double-walled tanks, sumps or containments whose walls on the stored product side are
resistant to permeation from particles which can generate potentially explosive vapours.
EXCEPTION:
Inner walls not resistant to permeation when using an inert leak detection medium.
•
The alarm pressure must be min. 30 mbar higher than any pressure occurring in the
interstitial space (from inside and/or outside).
•
Grounding (where applicable) according to valid regulations
•
Leak detection system is impermeable, according to chapter 6.4.6 of this documentation.
•
Mount the leak detector outside potentially explosive area.
•
Lead-throughs for the pneumatic hoses are sealed gas tight.
•
Leak detector (electric) is connected so that it cannot be switched off.
6.4 Function
test
Check functional and operational safety
•
every time after start up
•
on the basis of chapter 6.2 in the intervals stated there
•
every time after troubleshooting
6.4.1 Test
scope
(1) Poss. check the scope of work with the person responsible on site.
(2) Comply with the safety regulations for handling the specific stored product.
(3) (DL .. ONLY) Regeneration/replacement of the filter filling.
(4) Check the free passage of air (gas) in the interstitial space (chapter 6.4.2).
(5) Check the switching values with the test unit (chapter 6.4.3),
alternatively: check the switching values without test unit (chapter 6.4.4)
(6) Check the overpressure valve (chapter 6.4.5).
(7) Tightness test (chapter 6.4.6).
(8) Restore operating condition (chapter 6.4.7).
(9) Test report confirming functional and operational safety to be compiled by the qualified
person.
