OVERPRESSURE – LEAK DETECTOR DL ..
connected installation pump, find and
eliminate the leak (poss. check capacity of
installation pump, check correct setting of
pressure reducer).
the connected pressure cylinder, find and
eliminate the leak (poss. check correct setting of
pressure reducer). CAUTION: Leak detector
display begins at 150 mbar pressure.
(7) Filling can (should) be activated again to
ensure that the interstitial space is filled
completely.
(8) On reaching the leak detector operating pressure (pressure generator in leak detector
switches off), install pressure tube again or set both valves to setting "I". Remove pressure
instrument.
(9) Check functions as per chapter 6.4
6 Operating instructions
6.1 General
(1) Following impervious, correct connection of the leak detection system, the leak detector
can be presumed to work in the normal range.
(2) If the pressure generator switches on frequently or runs continuously, this indicates leaks
which must be eliminated in an appropriate period of time.
(3) An alarm always indicates a major leak or defect. Find and eliminate the cause quickly.
(4) The operator must regularly check that the "Operation" LED is working properly.
(5) Disconnect the leak detector from the power supply before performing and repair work.
(6) The operating lamp goes off when there is a circuit failure: the dry relay contacts open.
(7) (DL .. ONLY). When the filter filling changes colour from orange to colourless
(or green)
,
it must be
replaced or regenerated.
6.2 Maintenance
6.2.1 By the operator:
(1) Check the dry filter regularly
. When it changes colour from orange to colourless
(or green)
,
replace or
regenerate the filter filling.
(2) Check the filling in the pressure cylinder regularly. If the pressure is only just above the
pressure setting on the pressure reducer, refill or replace the cylinder.
6.2.2 Maintenance work and function check by qualified experts
