1 Safety instructions
• This operator’s manual has to be read, understood and observed before commissioning the
test system.
• If one of the following safety instructions is not or only partially observed, the Paul Lippke
Handels-GmbH can assume no responsibility for any consequential damages, defects or the
reliability of the test system.
• We proceed on the assumption that the operator will use this test system carefully and
sensibly.
• You must not continue system operation if any system malfunctions occur.
• The test system must not be modified with regard to its construction and design without
prior consultation of the manufacturer.
• This operator’s manual must be enclosed if the test system is resold.
• Please make sure that the test system is only connected to the mains power supply men-
tioned on the nameplate.
• Please also make sure that the connection pressure of compressed air supply does not ex-
ceed the maximum pressure.
• Please provide sufficient air circulation and install the test system in a sufficient distance
to other objects.
• Never clean the test system with any liquids if it is connected to the mains socket-outlet.
• Disconnect the test system from the mains line and remove the compressed air supply be-
fore opening its front or rear panel.
• Maintenance works which are possibly required may only be performed by the customer
service department of the Lippke company.

2 Introduction
2.1 System survey
The system LIPPKE 2000 SL (see figure 2.1) developed by the Paul Lippke Handels-GmbH
offers the user the option to test packages with regard to their impermeability and sealing seam
stability (burst test = BURST mode) and to their tightness (pressure test = LOSS mode).
In the burst test a linear pressure rise is created in the package until the package bursts. Thus the
burst pressure is a measure for the impermeability of the seams of the package.
For measuring the tightness of a package, first a pressure is built up inside the package. There will
be a pressure loss in the package during test time if the tested package is leaky. This pressure loss
is measured and displayed.
Figure 2.1: Package test system LIPPKE 2000 SL
The serial interface permits the output of test reports to a printer or PC.
2.1.1 The LIPPKE 2000 SL control unit
The LIPPKE 2000 SL control unit houses the micro controller and the pneumatic system. Here
the air supply is connected and guided through the package holding device to the package in a
controlled way. Operation and display take place via the front panel.
In general, the test result is displayed on the digital display. However, the use of a serial interface
is recommended for optimum documentation and for outputs on a printer. It is also possible to
link the system to a PC (e.g. via the ”Terminal Program” by WINDOWS

). Apart from this
result, all test parameters as well as date and time are transmitted. A corresponding printer can be
purchased via LIPPKE.

2.1.2 Holding stand and needle heads
A closed package is connected to the control unit by means of the package holding stand (see
figure 2.2).
Figure 2.2: Package holding stand
Two different types of needle heads are used in order to conduct compressed air into the package:
the mono needles (type 1B and type 2B) and the double needle type 3B.
Mono needles are suitable for almost all packages. There is no danger of measuring needle clog-
ging by the product, since here only one needle is used for air supply and pressure measurement.
Pricking into the package is made easier by the needle type 1B (see figure 2.3). Nevertheless the
use of a needle type 2B (see figure 2.4) is recommended for flat packages in order avoid
undesired damage to the underside of the package.
Figure 2.3: Needle Type 1B

Package test system LIPPKE 2000 SL Introduction

Figure 2.4: Needle Type 2B
In case of the double needle (see figure 2.5), the sensor line is lead separately into the package. If
very large air supply is required for measuring, back-pressure is possible when using a mono
needle. This effect occurs above all with packages made of materials permeable to air, like sterile
paper, Tyvek etc. An O-ring inside the needle head provides the sealing of both air channels.
Figure 2.5: Needle Type 3B
2.1.3 Clamping device
A package open on one side is connected to the control unit by means of the clamping device (see
figure 2.6). The open end of the package is sealed almost airtight between the clamps. Only the
two connections for air supply and pressure measurement are lead to the control unit.

2.2 General operating instructions
After switching on (power switch on the rear panel, see figure 3.3, page 16), the LIPPKE 2000 SL
control unit first displays the parameter last used (see figure 2.7).
Figure 2.7: Control unit, front panel
The two red LEDs on the left side of the display field indicate the active mode: The BURST
TEST LED indicates a burst test and the PRESSURE LOSS TEST LED indicates a pressure loss
test. Depending on the four LEDS on the right side, the digital display has different meanings:
 “mbar”: The current pressure is displayed in ”mbar”, if this LED lights up, otherwise in
”PSI”
 “∆P” signalises pressure loss in ”mbar” or ”PSI” (see above)
 With ”SEC”, test time is indicated in seconds and with
 ”MIN” in minutes.
The LED bar display below the numerical display field has the following meaning:
Burst test: The current internal pressure inside the package is displayed in the overall
range of 0 - 3000 mbar on the ”ACTUAL PRESSURE” display. Thus one
LED corresponds to 300 mbar.
Pressure loss test: The selected test pressure is displayed on the ”SET PRESSURE” display.
All 10 LEDS always light up. The current internal pressure of the package
is displayed on the ”ACTUAL PRESSURE” display. One LED is
extinguished for each pressure loss of 10%.
Setting of mode and pressure is performed in the left part of the operator panel. The ”TEST
MODE” key serves for changing to the desired mode. The function is activated by pressing the
”+”- or ”-” key, i.e. a pressure value or a pressure rise rate is displayed on the display. Then the
pressure can be set by means of the ”+”- and ”-” key. The values are changing the faster the
longer the key is pressed. In test system configuration (see chapter 6), you can determine whether
the factory-set default pressure unit ”mbar” shall be changed into the pressure unit ”PSI”.
