1 Safety information
1.1 General
WARNING
This operating manual contains instructions fundamental to the installation, operation and maintenance of the device that must be observed unconditionally. It
must be read by the assembler, operator and the specialized personnel in
charge of the instrument before it is installed and put into operation.
This operating manual is an integral part of the product and therefore needs to
be kept close to the instrument in a place that is accessible at all times to the responsible personnel.
The following sections, in particular instructions about the assembly, commissioning and maintenance, contain important information, non-observance of
which could pose a threat to humans, animals, the environment and property.
The instrument described in these operating instructions is designed and manufactured in line with the state of the art and good engineering practice.
1.2 Personnel Qualification
The instrument may only be installed and commissioned by specialized personnel familiar with the installation, commissioning and operation of this product.
Specialized personnel are persons who can assess the work they have been
assigned and recognize potential dangers by virtue of their specialized training,
their skills and experience and their knowledge of the pertinent standards.
WARNING
For explosion-proof models the specialized personnel must have received special training or instruction or be authorized to work with explosion-proof instruments in explosion hazard areas.
1.3 Risks due to Non-Observance of Safety Instructions
Non-observance of these safety instructions, the intended use of the device or
the limit values given in the technical specifications can be hazardous or cause
harm to persons, the environment or the plant itself.
The supplier of the equipment will not be liable for damage claims if this should
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 Technical Data section.
The instrument must be decommissioned and secured against inadvertent reoperationif a situation arises in which it must be assumed that safe operation is
no longer possible. Reasons for this assumption could be:
FISCHER Mess- und Regeltechnik GmbH Safety information | 1
BA_EN_MA15_ATEX 5 / 36
• evident damage to the instrument
• failure of the electrical circuits
• longer storage outside the approved temperature range.
• considerable strain due to transport
Repairs may be carried out by the manufacturer only.
A professional single conformity inspection as per DIN EN 61010, section 1,
must be carried out before the instrument can be re-commissioned. This inspection must be performed at the manufacturer's location. Correct transport and
storage of the instrument are required.
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 maintenance, inspection and installation work is carried out by qualified specialized personnel.

2.3 Intended use
The units may only be used for the purpose stipulated by the manufacturer.
The units serve to measure over-pressure and under-pressure in industrial ap-
plications in areas at risk of explosion acc. to directive 2014/34/EU.
The optional installed switch elements are low-action contacts, mechanical
magnetic spring contacts, inductive proximity switches in a slotted design or capacitive rotation angle encoder.

If the set limit values are exceeded, the out-
put power circuits are opened or closed.
The corresponding setup regulations are to be considered for each application
case.

2.5 Design and mode of operation
The measuring element, the concentric corrugated diaphragm, is clamped
between two flanges and the medium is applied on one side.
The diaphragm bulges elastically from its normal position as a result of the applied pressure. The linear movement is proportional to the applied pressure. A
rod assembly on the side of the diaphragm that faces away from the medium
captures the expansion movement and transfers it to the indicator.
The measurement display is shown on a 270 W° scale.

3 Assembly
3.1 Generalities
The instrument may only be installed and commissioned by specialized personnel familiar with the installation, commissioning and operation of this product.
Specialized personnel are persons who can assess the work they have been
assigned and recognize potential dangers by virtue of their specialized training,
their skills and experience and their knowledge of the pertinent standards.
WARNING
Mounting pressure transmitters
During assembly, observe the respective national and international guidelines
and safety regulations.
Only mount the unit to systems that are depressurized. Only ever operate the
unit within the permitted measuring range or below the maximum overload.
Fig.5: Shutoff valve.
The device is set ex-works for vertical installation, however any installation position is possible.
To guarantee safe working conditions during installation and maintenance, suitable stop valves must be fitted in the system (see accessories). By means of
the manometer shutoff, the unit
• Can be depressurized or taken out of operation.
• Be disconnected from the power supply within the applicable system for repairs or inspections.
3.2 Process connection
• By authorized and qualified specialized personnel only.
• The pipes need to be depressurized when the instrument is being connected.
• 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)
WARNING
Earth connection via the system earth
During assembly, ensure that the earth connection between the unit and the
system earth is ensured. The connection to the system earth is realised via the
process connection. Therefore, never use an insulated Teflon tape or similar.
Design the process connection acc. to EN 837 and use a suitable flat seal.
3.2.1 Measuring lines that need to be connected
The following points need to be observed when connecting the pressure line:
• To ensure there is no influence on the measured values, severe bends and
coils in the wire should be avoided.
• To prevent deposits, there should be a continuous incline or drop of at least
8%.
• When measuring steam pressure, a water bag-forming loop must be
provided due to the temperature (see accessories).

• The transmitter must be positioned below the measuring point for liquid
measurements. Vent the pressure line before commissioning.
• The transmitter must be positioned above the measuring point for gas
measurements.
3.2.2 Pressure surge absorption
Pulsating pressure on the system side can lead to functional problems. We recommend installing a damping element in the pressure connection lines as a
protective measure.
