Fig. 1: Exterior view and dimensions
The leak detector Europress generates a constant overpressure in
the interstitial space of the tank and triggers an alarm in the case of a
pressure drop.
Europress contains the following elements in an impact-resistant
plastic housing: display elements and controls, a pressure pump, a
pressure switch, a safety valve, a printed circuit board with the elec-
tronic components for processing the output signal, a filter and three
hose connections for the pneumatic connection to the interstitial
space of the tank.
The green LED “Supply ON” lights up when mains voltage is avail-
able. The alarm is indicated visually and audibly and is made avail-
able via a voltage-free relay contact (1 changeover contact).

Product description
Europress 9
Drying filters (not included) are used to dry the air compressed for
the operating pressure to a residual humidity level of approx. 10 %
and a filter is used to remove the dust particles. The dried and fil-
tered air is pumped into the interstitial space of the tank. Pressure
fluctuations in the interstitial space are compensated for by the pump
and the safety valve.
3.1 Function
The green LED “Supply ON” lights up when mains voltage is avail-
able and the device is ready for operation.. The pump integrated into
the leak detector draws in air via the drying filter and pumps it via the
pressure line to the tank's interstitial space until a constant overpres-
sure has been built up.
The pressure switch measures the pressure in the interstitial space
via the measurement line and keeps it at a constant level together
with the pump. The safety valve at the pump opens if the pressure is
too high in order to prevent the interstitial space test pressure (0.6
bar) from being reached.
If a leak occurs in the tank's inner or outer wall either above or below
the level of the stored liquid or the ground water, and if this leak is
greater than the pump's pumping capacity, the overpressure will
drop. When the alarm threshold is reached, the red LED “Alarm” and
the audible alarm are activated and the relay is energised.
The audible alarm can be muted with the button “Mute”. The switch-
ing point for "Alarm on" is at least 30 mbar higher than the static
pressure of the stored liquid or the ground water.
3.2 Operating modes
Europress is equipped with an output relay to transmit the alarm sig-
nal to additional external devices. If no error condition is present, the
relay is de-energised. In the case of an alarm, the relay is energised.
Europress can be operated with or without additional external de-
vices. The following types of additional devices can be used: visual
and audible alarm units, telecommunication devices, building control
systems, building automation systems, etc.

ing by the enclosed cable gland.
 Close any cable glands at the bottom of the housing that are not
used by means of the enclosed plugs.

Mounting and commissioning
16 Europress
Power supply
Connect the leak detector to mains by means of a permanently in-
stalled cable such as NYM-J 2 x 1.5 mm².
1. Route the mains cable through the upper or bottom cable gland
into the leak detector.
2. The phase must be connected to terminal L1, the neutral con-
ductor to terminal N. The leak detector supply cable must have
a separate fuse (max. 16 A). Do not connect it to the circuit of
other electrical devices.
Output
The output signal of the leak detector is made available via a volt-
age-free relay contact (1 changeover contact).
 Permanently install the relay cable, route it through the upper or
bottom cable gland into the leak detector and connect it to the
terminals with the corresponding designations.
 Safely isolate the relay cable. The isolation characteristics of the
relay cable must at least comply with IEC 60227 or IEC 60245.
If no error condition is present, the relay is de-energised. In the case
of an alarm, the relay is energised.
CAUTION
Destruction of the switching contact and adverse effects on the
function of electrical systems due to voltage peaks when induc-
tive consumers are switched off.
 Use commercially available standard RC combinations such as
0.1 µF/100 Ohm for inductive consumers.

Mounting and commissioning
Europress 17
9 V battery for alarm in the case of power failure
If a standard 9 V battery is connected, an alarm sound is activated in
the case of a power failure. The alarm sound cannot be muted; it re-
mains on until mains power is available again. When mains power is
available again, the device immediately resumes operation. If a leak
has occurred in the meantime, this is indicated.
6.5 Connection line
Hoses from the leak detector to the tank to be monitored, see also
fig. 6 and fig. 7, page 19.
1. Use pressure-proof (at least PN10 for tanks containing inflam-
mable liquids), oil- and water-resistant plastic hoses 6 x 2 mm
for the measurement hose (red), the suction hose (green) and
the pressure hose (transparent. The hoses must be resistant to
the stored liquid and its vapours.
2. Protect the plastic hoses by means of rigid, weather-proof pro-
tective pipes. According to the German TRbF 20 No. 4.1.4 sec-
tion 8, the protective pipes must be resistant to the permeation
of inflammable liquids and their vapours.
3. The connection lines must have the full cross section over the
entire length, there must be no bends and indentations.
4. Do not fit any shut-off elements.
5. Hose connections must be secured by means of hose clamps
which fit over the entire circumference.
Under the following conditions, you may also use quick-action cou-
plings (shutting off at one end, nominal diameter 7.2, Rectu Base

Mounting and commissioning
18 Europress
type 26) at the tank side of the pressure line and the measurement
line of the interstitial space:
• The coupling part with the shut-off element is directly and per-
manently mounted to the tank.
• The connection piece for the pressure line and the measure-
ment line is secured by means of one hose clamp for each
hose.
• The pressure line and measurement line must be mounted and
connected in such a way as to prevent twisting.
Quick-action couplings enable factory-filling of the interstitial space
with dried air which considerably reduces the time required on site
for commissioning. The following must ensured:
• There is only dried air (or nitrogen) in the interstitial space.
• The coupling part at the tank end must not get dirty during
mounting in order to prevent damage to the seal.
6. Slide the cover over the connections to protect hose connec-
tions.

Leak test
1. Check the connection lines for leaks prior to connection to the
interstitial space. To do so, perform a leak test with 600 mbar.
CAUTION
Damage to or destruction of the measurement system if the test
pressure at the connected Europress exceeds 600 mbar.
 Make sure the test pressure does not exceed 600 mbar.

The connection lines can be considered to be tight if the pres-
sure drop within a period of 30 minutes is less than 20 mbar.
2. Connect the connection lines to the interstitial space of the tank
after a successful leak test.
Basic filling
The pump of the leak detector must not exceed the pump capacity of
100 l/h.
1. Fill the interstitial space to obtain a pressure of approx. 500
mbar. Use an installation pump with a greater capacity for this
purpose.
2. The intake air must be dried by means of a sufficiently large dry-
ing filter.
3. Once a pressure of 500 mbar has been built up, disconnect the
installation pump and connect the leak detector.
