1 Safety informat ion
General
This manual contains information that must be observed in the interest of your own safety and to avoid
material damage. This information is supported by symbols which are used in this manual as indicated.
Please read this manual before starting up the device. Store this manual in a place that is accessible to
all users at all times.
If difficulties occur during startup, please do not intervene in any way that could jeopardize your warranty
rights!
Warning symbols
DANGER!
This symbol indicates that personal injury from electrocution may occur if the appropriate precaution-
ary measures are not taken.
CAUTION!
This symbol in connection with the signal word indicates that material damage or data loss will occur
if the respective precautionary measures are not taken.
Note symbols
NOTE!
This symbol refers to important information about the product, its handling, or additional benefits.
1.1 Hazardous materials
Using hazardous materials as a medium may result in abrasive and corrosive damage to components
of the product that come into contact with the medium. The medium may leak and present a fire hazard
and a risk to health.
Carry out a risk assessment taking into consideration the safety data sheet for the relevant hazardous
substance for mounting, operation, maintenance, cleaning, and disposal:
• Comparison and systematic checking of the durability of the components of the product that come
into contact with the medium and the admissible environmental influences.
• Assessment of the risk to people and the environment.
• Assessment of the fire hazard due to the product materials, the admissible environmental influences,
and the voltage supply.

2 General information
2 General information
DANGER!
The device is suitable for measuring pressure in gases and liquids without solids content.
In the SIL version (functional safety), this device is used in safety-related systems for minimum,
maximum and area monitoring that fulfil the requirements of the series of standards
IEC 61508:2010.
A failure of the device or other devices connected to it, e.g. due to an operating error, can lead to
dangerous malfunctions of the whole plant.
Therefore please also observe the corresponding safety manual from the device series.
NOTE!
Read this operating manual before putting the device into service. Keep the operating manual in a place
that is accessible to all users at all times.
All necessary settings are described in this operating manual. Nevertheless, should problems be en-
countered during startup please do not make any unauthorized manipulations. This could endanger your
rights under the warranty!
Please contact the nearest branch office or the head office.
2.1 Areas of application
General information
The pressure transmitter with HART® interface combines maximum precision with simple operation. It
is used to measure the relative or absolute pressures of gases, vapors, and liquids. The integrated LCD
display shows the measured values and device data.
The pressure transmitter with flameproof enclosure can be installed up until zone 0. The housing and
sensors are manufactured from high-grade stainless steel. Various flush-mounted process connections
are available for applications with hygienic requirements, including PEKA connection system (see data
sheet 409711).
Diaphragm seals can also be connected for specific process technology applications (see data sheets
409772 to 409784).
The transmitter is programmable and therefore readily adaptable to a variety of different measurement
tasks. An easy-to-use setup program is available as an accessory to enable operation via the interfaces.
A rotary knob makes manual operation on-site very convenient and quick.
The pressure transmitter with 4 to 20 mA and HART® protocol was evaluated with regard to functional
safety and is certified by exida according to IEC 61508/-1/-2/-3. These measuring devices are suitable
for monitoring process level and process pressure up to SIL2. Further details can be found in the Safety
Manual.
Use in „Ex-area“
The device is permitted for use in the „Ex-area“. The device is flameproof enclosed and ca be mounted
in Zone 1!
Functional safety use
In the SIL version, the device is permitted for use according to IEC 61508 if it has a corresponding iden-
tification marking on the nameplate.

CAUTION!
The device‘s membranes must not be damaged at the process connection!
Do not insert any objects into the drilled holes of the pressure connections!
The device must be sent back if there is damage to the housing or membrane!

Operating Manual
The operating manual describe the mounting, the electrical connection, the startup and operation of the
device.
Safety manual (option)
The safety manual describes the safe application with the installation according to IEC 61508.
Calibration certificate
The device is supplied with a calibration certificate and a setup print-out.
These documents contain information about the set parameters and/or the measured parameters for the
respective device.
If the calibration certificate is lost or if you need another copy, the calibration certificate can be requested
from the manufacturer by specifying the device's F number (see nameplate). You will find the supplier's
address on the back cover of the manual.
Setup program (option)
The setup program is available as an option: part no. 00537577
All the device's parameters can be conveniently checked and adjusted using the setup program - there
are also additional functions, e.g.:
• Recording the measured values
• Graphical view of temperature and pressure
• Detailed diagnostic messages
• Display of the complete order code and the device configuration (for follow-up orders)
The setup program accesses the device via
• the JUMO interface (standard) or
• the HART® interface (optional)

DANGER!
The JUMO interface must not be used in the Ex-area!
The device may only be operated using the rotary knob or the HART® interface!
PC interface cable (option)
Available as an accessory: PC interface cable with USB/TTL converter and two adapters (USB transmit-
ter cable), part no. 00456352.
The device can be connected to a PC's USB port via the JUMO interface with the PC interface cable.
HART® modem (option)
Available as an accessory: HART® modem for USB, part no. 00443447.
The device can be connected to a PC's USB® port via the HART® interface with the HART® modem.
Diaphragm seal (option)
Available as an accessory: see data sheets 409770 to 409786.
Diaphragm seals are used for adjusting to particular applications if conventional pressure connections
cannot be used.
CAUTION!
Diaphragm seals are installed by default and must not be removed from the device!
