1 Safety guidelines
1.1 General
WARNING
This operating manual contains instructions fundamental to the installation, op-
eration 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 re-
sponsible personnel.
The following sections, in particular instructions about the assembly, commis-
sioning 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 manu-
factured 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 person-
nel 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.
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 theinstrument 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.

1 | Safety guidelines FISCHER Mess- und Regeltechnik GmbH
6 / 60 BA_EN_EA15
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 Product and functional description
2.1 Lieferumfang
• Measured value display EA15
• Operating instructions
2.2 Use as intended
The EA15 is a measuring value display unit for measuring transducers with out-
put signals for current and voltage acc. to IEC 60381. Up to four measuring
transducers in two or three-conductor versions can be connected.
Typical applications
• Universal measurement display in an industrial environment.
Important features
• 2.8" (7.2 cm) TFT Touch LCD colour display
• Configurable colour switching
• 2 or 4 channel mode with …
– 2 or 4 configurable analogue inputs
(for uniform signals (0/4 … 20 mA, 0 … 10 V) acc. to IEC 60381)
– 2 or 4 configurable analogue outputs
(with possibility of characteristic curve spread and reversal with any off-
set)
– 2 or 4 configurable switching outputs
(with potential-free relay contacts or semiconductor switches)
• Optional Modbus RTU interface
– Units with Modbus interfaces do not have analogue nor switch outputs
• USB interface
• Mathematical functions like formulas or tables
• Optional data logger function with data storage on conventional Micro SD
cards
• Configuration of all parameters and a measuring point protocol(1) are pos-
sible via an optionally available PC software
(1) parameter profile that can be saved and loaded

2.4 Design and mode of operation
The measuring signals of up to four connected measuring transducers can be
analysed simultaneously by the microcontroller electronics. The configurable
2.8" touch display can display up to four measuring values at the same time. A
configurable colour switch serves to present specific operating modes. Option-
ally, the device can be delivered with a data logger function.

FISCHER Mess- und Regeltechnik GmbH Product and functional description | 2
BA_EN_EA15 9 / 60
All parameters can also be set on the device via the touch display or (optionally)
via a PC software. The measuring value display unit has a USB interface to
which a USB stick can be connected for this purpose. For instance, the USB
stick can be used to allow simple configurations to be exported to other devices.
The PC software also allows a measuring point protocol (2) .
Units with analogue and switch outputs
The processed input signals are converted into the following output signals:
• 2 or 4 configurable switching outputs Parameters, such as activation and
deactivation points, switching function or delay, are available for this pur-
pose. The switching states are displayed with symbols on the display.
• 2 or 4 analogue outputs with configurable output range. Every output signal
can be set freely within the signal limits (see Technical Data). The charac-
teristic curve change can be made in a linear, rooted, tabular or mathematic
form proportional to the displayed value.
Units with Modbus RTU interface
Units with Modbus RTU interface do not have analogue or switch outputs
The input signals can be queried via the Modbus and processed by the Master.
For more information about this topic, please reference the product user manual
and the Modbus reference manual.(http://www.fischermesstechnik.de/de/

3 Installation and assembly
3.1 General
The device is designed for installation onto flat assembly plates. For screw con-
nection to the assembly plate, the device features four assembly bores on its
back, which can be used for Ø 3.5 mm tapping screws.
Optionally, the device can be delivered with a wall-mounting plate.
The enclosure protection type IP 65 is only guaranteed, if a suitable power sup-
ply cable is used (see accessories) and the rubber strap is closed tightly.
