happen.
1.4 Safety Instructions for the Operating Company and the
Operator
The safety instructions governing correct operation of theinstrument must be
observed. The operating company must make them available to the installation,
maintenance, inspection and operating personnel.
Dangers arising from electrical components, energy discharged by the medium,
escaping medium and incorrect installation of the device must be eliminated.
See the information in the applicable national and international regulations.
Please observe the information about certification and approvals in the Tech-
nical Data section.
1.5 Unauthorised Modification
Modifications of or other technical alterations to the instrument by the customer
are not permitted. This also applies to replacement parts. Only the manufacturer
is authorised to make any modifications or changes.
1.6 Inadmissible Modes of Operation
The operational safety of this instrument can only be guaranteed if it is used as
intended. The instrument model must be suitable for the medium used in the
system. The limit values given in the technical data may not be exceeded.
The manufacturer is not liable for damage resulting from improper or incorrect
use.

1.7 Safe working practices for maintenance and installation work
The safety instructions given in this operating manual, any nationally applicable
regulations on accident prevention and any of the operating company's internal
work, operating and safety guidelines must be observed.
The operating company is responsible for ensuring that all required mainten-
ance, inspection and installation work is carried out by qualified specialized per-
sonnel.

2.3 Intended use
The MS11 contact manometer is a combined measuring and switch device for
pressure measurements under difficult conditions, such as pressure impacts, vi-
brations, frequent switch processes or high requirements on the switch perform-
ance.
The device is suitable for gaseous media and fluid media. Please contact the
manufacturer before using this unit with dirty or aggressive media because the
unit needs to be adapted in terms of the parts that come into contact with the
media.
The device can be used as a functional safety components (SIL) as agreed with
the manufacturer (see order code).
The device is to be exclusively used for the applications agreed between the
manufacturer and the user.

2.5 Design and mode of operation
The basis for this measurement and switch unit is a sturdy non-sensitive dia-
phragm measuring unit that is suitable for measuring over and under-pressure.
In the rest position, the spring forces on both sides of the membrane are bal-
anced out. Due to the pressure or underpressure to be measured, a single-
sided force is created on the membrane which shifts the membrane system
against the measurement range springs up to compensation of the spring
forces. In case of overload, the membrane supports against the metallic support
surfaces.
A centrally positioned tappet transfers the movement of the membrane system
on the motion train and operating elements of the micro-switches.

3 Assembly
3.1 General
The device is designed for a direct process connection acc. to DIN EN 837. Op-
tionally, the device can also be supplied for wall mounting or with an installed
switch panel set.
NOTICE!At the factory, the device is calibrated for vertical installation and
only this installation position is allowed.
To ensure safety during installation and maintenance, we recommend installing
a suitable shut-off valve on the system (see accessories). A shut-off valve offers
the following advantages:
• The device can be depressurized or decommissioned.
• The device can be disconnected from the power supply within the applic-
able system for repairs or inspections.
• A function test of the device can be performed on-site.
3.2 Process connection
• By authorized and qualified specialized personnel only.
• The pipes need to be depressurized when the instrument is being connec-
ted.
• Appropriate steps must be taken to protect the device from pressure surges.
• Check that the device is suitable for the medium being measured.
• Maximum pressures must be observed (cf. Tech. data)
The pressure line must be kept as short as possible and installed without any
tight bends to avoid delays.
The pressurized line must be installed on a gradient so that no air pockets can
be created when measuring fluids and that no water pockets are created when
measuring gas. If the required inclination is not reached, water or air filters must
be installed at suitable places.
In the case of fluid media, the pressurized line needs to be vented because dif-
ferent fluid pillars in the lines can distort measurements.
If water is used as a measuring medium, the unit must be protected against
frost.
Pulsating pressure on the system side can lead to wear and functional prob-
lems. To safeguard this, we recommend installing absorption elements in the
pressure line.

In the operational status, the reactor pins need to be set so that the measure-
ment display follows the pressure changes with a delay.
