3 Safety instructions and precautionary measures
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
or repaired, or if the unit is used in a manner that does not comply with the intended usage of the
unit, or is contrary to the applicable regulations.
WITT-GASETECHNIK GmbH & Co KG is not liable for damages arising from failure to observe
these instructions.

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.

5 Setting up and installation
In this section you will find information on the correct location for setting up the device, and notes
on installations.
5.1 Checking for transport damage
Note!
Perform a visual inspection for external damage and damage to cables / tubes (nicks, dam-
age to the insulation).
The Leak-Master®Easy Plus (LME+) control is supplied ready to use.
It must be correctly transported.
5.2 Place for setting up
Note!
Never subject the device to direct sunlight or sources of large amounts of heat.
Note!
Do not operate the device in an environment with increased electromagnetic activity (out-
side the standardised limits).
Place the undamaged unit on a solid surface in a place protected from the weather and se-
cured against accidents.
During setting up observe the ambient conditions stated in the technical data (Section 8)
(e.g., ambient temperature, safety zone, humidity, dust, altitude).
5.3 Electrical installation
Establish the connection to the mains using the plug.
The installation of the electrical connections as per the electrical circuit diagram must be per-
formed in accordance with VDE 0100.
Observe following instructions:
Note!
The usage of cables that are not approved can result in irreparable damage to the cables in
the case of heavy mechanical loading. In the case of cables that are not twisted or screened,
signal processing may be imprecise.
Note!
Protect the cables from mechanical loads (e.g. using a suitable cable duct). Excessive me-
chanical loading can result in irreparable damage to the cable.
Note!
It is imperative that the supply voltage in the Technical Data is provided.

5.4 Installation of the hose connections
Releasing of a hose connection
1 Press the coloured circle of the plug connection to release the arrest of the
hose.
2 Afterwards pull out the hose.
Establish a hose connection
Insert the hose into the plug connection as far as possible.
The arrestor will lock the hose automatically.
Connect the Leak-Master®Easy+ control to a Leak-Master®Easy
If a 12 mm hose is used for the compressed air supply of the LME to be connected, first install
the both adaptors as described in Section 5.4.1.
Remove compressed air supply
from the LME and connect to the
compressed air connection of the
LME+ control.
Connect the delivered compressed
air hose to the compressed air outlet
of the LME+ and the compressed air
inlet of the LME.
Disconnect the vacuum hose from
the measurement chamber and
connect to the vacuum connection
of the LME+ control.
Connect the delivered vacuum hose
to the vacuum outlet of the LME+
and the vacuum connection of the
measurement chamber.
After installation the appearance of the complete setup
should be similar as the picture below.
