Operation
24 Europress
The red LED “Alarm” remains on.
4. Immediately notify the installation company.
5. When the problem has been fixed, you must perform a full func-
tion test as per chapter 7.2, page 24.
Determining the tank with the leak if several tanks are con-
nected to one leak detector
1. Close all stop cocks of the two distributors (pressure line and
measurement line).
2. Connect a pressure gauge to the lateral connection of the lateral
connection of the measuring valve.
3. Open the pair of stop cocks of the first tank.
4. If the pressure gauge does not indicate a pressure drop, close
the two stop cocks of the first tank and open the pair of stop
cocks of the second tank.
5. If the pressure gauge does not indicate a pressure drop, con-
tinue with the same test at all further tanks until you have lo-
cated the defective tank.
6. When the reason for the alarm has been properly fixed, open all
stop cocks of the connected tanks.
7.2 Function test
1. The function of the leak detector must be tested each time it is
commissioned and at least once per year by an expert and after
each alarm and troubleshooting activity.
2. Create a test report after each function test and keep it along
with the other documents for the leak detector.
The pressure switch integrated in the leak detector and the over-
pressure safety valve may only be adjusted and calibrated by the
manufacturer or by trained staff.
Function test by simulation
1. Set the test valve (white connection) to position "Vent".
Air is supplied to the interstitial space of the tank.
The pressure in the interstitial space drops and the leak detector
triggers an alarm.
2. Set the test valve (white connection) to position "Normal Opera-
tion".
