It is imperative that the following safety instructions and precautionary measures are observed and
followed. They are intended to avoid hazards that can arise during the use of the system.
In addition, the applicable national health and safety regulations and safety regulations from the
trade associations are to be observed. For example, in Germany:
Health and safety regulations from the trade associations
a) DGUV Vorschrift 1 Grundsätze der Prävention (principles of prevention)
b) DGUV Vorschrift 3 Elektrische Anlagen und Betriebsmittel
(Electrical Systems and Equipment)
c) BGR 500 Kap. 2.33 Gase (Gases)
No claim is made that this list is absolute.
Along with the instruction manual and the health and safety regulations applicable in the country
and place of use, recognised engineering regulations for safe and correct working are to be ob-
served.
The operating organisation must ensure that only authorised persons work on or with the system.
The gas mixer is built to the state of the art and is safe to operate. Hazards can be produced by the
gas mixer if it is used incorrectly by untrained personnel, or is not used for the purpose intended.
3.1 General safety instructions
Caution!
Only persons who have been instructed on the operation of the system and who have read
and understood this manual are permitted to use the system.
Observe national technical regulations on the handling of gases, e.g. applicable health and
safety regulations.
Any unauthorised modifications or changes to the system are forbidden for safety reasons.
Malfunctions arising during operation may only be rectified by trained personnel.
Maintenance- and repair tasks may only be performed by trained personnel.
During all maintenance- and repair tasks ensure that the device is isolated from mains electric-
ity and is de-pressurised.
All supply pipes to and from the device are to be designed for the maximum / minimum permit-
ted gas pressure. If this is not possible, it must be ensured that the permitted pressures cannot
be exceeded respective undercut by means of the installation of suitable fittings, e.g., bursting
discs, safety valves or vacuum limiter.
The material for the gas pipes, all fittings installed there (e.g. shut-off valves, gauges, etc.) and
all sealing elements there must be designed for the related type of gas.
The maximum gas inlet pressures in the technical data must not be exceeded. If necessary
this is to be ensured by the installation of safety valves or bursting discs.
Also check cables for damage, as well as the gas pipes for breaks / leaks.
3.2 Liability
The liability for the function of the unit passes in all cases to the owner or operating organisation as
far as the unit is operated by persons who do not belong to WITT Service, is incorrectly maintained

4 Description of alternative control «Leak-Master®Easy Plus»
The benefits of the Leak-Master®Easy Plus alternative control are:
Easy intuitive handling by means of the Gas Control 50 (GC50) SPS with touch screen moni-
tor.
User / tester management
Product management with test parameter individually stored for the respective product
User and product selection by means of barcode scanner (option)
Electronically documentation of the test results
Export and back-up of the test results
via LAN network to a PC or
The Leak-Master®Easy Plus (LME+) alternative control can be used with every Leak-Master®Easy
Modell (LME) model.
The compounds for vacuum generation and setting of the LME will still be used. The LME+ control
takes over the function of the ball valve (6) in the compressed air supply. In addition the vacuum
level need not be set by means of the operating pressure regulator (5). Instead of that the reached
vacuum is measured by a pressure transmitter (PIT). If the vacuum reaches the value set at the
GC50 a solenoid valve closes and further evacuation is stopped.
The ball valve (6) and the operating pressure regulator (5) can stay in the system. So fast back fit-
ting to the original state of the LME is possible.
Important Note!
For proper function of the LME+ control it is necessary that the ball valve (6) is open and
that operation pressure regulator (5) is tensed.

6.5 Testing products
For testing products the Leak-Master®Easy+ (LME+) control must be proper connected to a Leak-
Master®Easy (LME) and a compressed air supply (Section 5.4). At the connected LME the ball
valve (6) must be open and the pressure regulator (5) must be tensed – the LME+ control will in-
herit their functionality.
On testing products always also observe the manual of the LME.
After a product is selected for testing the measurement
window is shown in Display.
It is shown:
«Start», to show a test can be performed.
the name and number of the product as well as the
measurement number.
the actual vacuum (only Admin) / the set test vacuum.
the set measuring time.
Only for the Admin the following additional operating possibilities are faded in:
By means of the button Auto a measurement will be started and repeated until this is
manual interrupted. A decision in evaluation screen is not required. The number of the al-
ready performed measurement cycle is indicated below the button.
This function can be used to perform an endurance test for a product packaging.
At the right side the set test vacuum and measuring time for the selected product can be
directly changed in the measurement window. This is helpful to determine the test param-
eter for a new product.
Place the product in the test chamber according to the separate manual of the LME.
Close the lid of the test chamber.
Press the button «START».
Note!
By pressing the button «STOPP» or «Break» the meas-
urement can be interrupted at any time.
The compressed air supply opens and the vacuum suction
nozzle generates vacuum in the test chamber. If the set
vacuum setpoint is reached, the test chamber is locked and
disconnected from the vacuum generation by means of the
solenoid valve in the vacuum pipe. Afterwards the com-
pressed air supply is closed.
Now an evaluation screen is indicated and the countdown
of the set measurement time starts.
During the measurement time the user has to check wheth-
er there are leakages in the packaging of the product.
Press «OK» if the packaging is tight.
or
Press «ERROR» if the packaging is not tight.
After expiring of the measurement time the measurement chamber is aerated.
The evaluating screen will be indicated until the user made a decision. If the decision is made the
measurement is stored together with the decision of the user.
Afterwards the measurement window is indicated again and the next measurement can be started.

The last 100 test results are stored in a Ring Data Memory and can be displayed in the Data Ad-
ministration. The last 10,000 test results, maybe more, are stored in a “CSV file” (Data Safety
Memory). This file can be read and saved (see Section 7.2) by means of a browser or the optional
available evaluation software “GasControlCenter”. The actual test results in the Ring Data
Memory are also saved in that file.
A warning occurs in time before the limit of the Data Safety Memory is reached.
Warning limits are:
Below 10 % free – a warning after every 25 measurements
Below 2 % free – a warning after each measurement

By means of the button “ON” or “OFF” the scanner is switched on or off.
The scanner is activated if the button shows ON with green background.
You can state from which position on the read barcode is used (start position 1 to 20).
The maximum length of the barcode is limited to 20. If the Code Length is set to “0” means that the
barcode is not used.
Per default the complete string of the fed barcode is processed by the control system. If additional
information about the product (e.g. production date) is included the barcode it is necessary to dis-
regard this additional information. For this purpose the start position and the length of the string to
be used from the barcode can be set under this menu item.
Example:
The string of the bar code is 23XXXXXX1004.
XXXXXX is the area which contains the necessary information to identify the product.
To regard only this area when scanning you have to set the following:
start position = 3
code length = 6 (maximal 20)

7 Connection to a PC
For reading out data you need a network-compatible PC (TCP/IP-protocol) with installed
MS Internet Explorer.
7.1 Establish a LAN connection
To address the LME+ via network the subnet mask and IP-address normally must be changed in
the control system of the LME+.
The default settings of the LME+ control system are:
IP- address: 192.168.1.254
Subnet mask: 255.255.255.0
At the PC and the LME+ the same subnet mask must be set. The first three blocks of the IP-
address must be identical, in the fourth block must be different numbers within the range of 0 –
255. Every IP-address must be unique in a network.
Note!
Which values you can use is dependent of your locally network.
Ask your network administrator which subnet mask, IP-address and if necessary gateway
you shall use (below these values will be called «your subnet mask» and «your IP-address»
etc.).
Establish a connection between LME+ and the PC with a network cable (max. length 5 meter.
For greater distances a switch must be interconnected as repeater).
At the Leak-Master®EASY+:
Log in as «Administrator».
Select options to change to options.
Select System Option to change to the system options.
A window is shown in which the data which are relevant for the LAN connection can be set:
Input «your IP address» at IP address.
Input «your Subnet» at Net mask.
If necessary change the address for the Gateway.
Select Store to save the settings before restarting the device.
or
Select Finish to return to the option selection.
Restart the LME+ to take over the changed settings.

At the PC:
Open a browser at a PC in the same network and type in the address
ftp://«your IP address»
to establish the connection to the LME+ control system.
In the browser window the folder and files
on the control system will be shown.
Only the folder «a» is relevant for data ex-
change.
«a»
Here data which are designated to be pro-
cessed by the control system are to be
stored.
«b» only for internal use.
«media/USB1»
data from the control copied to an USB stick, e.g. “USB1”.
Attention!
Always use the folder «a/» or «a/dat» to write data to the control system.
Any change of files in other folders can cause malfunctions of the device.
7.2 Data exchange
Note!
We recommend to use the optional available evaluation software «GasControlCenter» for
data exchange.
7.2.1 Copy data from the control system to PC
Establish a network connection to the Leak-Master as described in Section 7.1.
Change to folder «a/DAT/».
The following files will be shown in
the browser window:
MEAS_DAT.CSV
contains measurement data.
PROD_DAT.CSV
contains the data of the
stored products.
USER_DAT.CSV
contains the data of the
stored users.
Copy the desired files with e.g. Copy/Paste to the hard disk of the PC.
Start Excel.
Open the “CSV-files” in Excel. Choose the data type “text files”.
Note!
If you open the files with double-click Excel often does not recognize the correct data type.
In this case the data are not displayed correct.
