A dangerous situation may possibly occur, which can lead to burns
due to hot surfaces or liquids if they are not avoided.
Warning!
This device is designed for connection to hazardous electric
voltages. Ignoring this warning can result in severe personal injury or
mechanical damage. To avoid the risk of electric shock and fire, the
safety instructions of this manual must be observed and the
guidelines followed. The specifications must not be exceeded, and
the device must only be applied as described in the following. Prior to
the commissioning of the device, this manual must be examined
carefully. Only qualified personnel (technicans) should install this
device. If the equipment is used in manner not specified by the
manufacturer, the protection provieded by the equipment may be
impaired.
Warning!
No dangerous voltage may be connected to the device before its per-
manent installation has been completed, and the following measures
should only be carried out when the device is in a de-energized state
and under ESD-safe conditions:
Installation, assembly and disassembly of pipelines.
Troubleshooting the device.
Warning!
The front panel of the device must not be opened, as this may da-
mage the contacts for contacting the UMU-FD front display.
The device does not contain any internal DIP switches or program-
ming jumpers.

Triangle with exclamation mark: Warning / Regulation. Operations
that can lead to life-threatening situations. The manual must be read
carefully before installing and commissioning the device in order to avoid
serious injuries or mechanical destruction.
The CE-Mark is the visible sign that the device complies with the regula-
tions.
The double isulation symbol is the symbol that the device meets
special requirements for insulation.
2. transport, packaging and storage
2.1 transport
Inspect the device for a damage that may have occurred during transport. Report
obvious damage immediately.
2.2 packaging
Do not remove the packaging until immediately before assembly. Keep the packa-
ging, because it provides optimal protection during transport (e. g. changeable
installation location, return).
2.3 storage
Avoid the following influences during longer storage:
-Direct sunlight or close to hot objects
-Mechanical vibration, mechanical shock (hard set up)
-Soot, steam, dust and corrosive gases
If possible, store the device in the original packaging or appropriate packaging.

3. Safety rules
Further important safety instructions can be found in the individual
chapters.
Definitions:
Hazardous voltages have been defined as the range: 75...1500 Volt DC and
50...1000 Volt AC.
Technicians are qualified persons educated or trained to mount, operate, and also
trouble-shoot technically correct and in accordance with safety regulations.
Operators, are persons who set or operate the pushbuttons or potentiometers of the
product during normal operation and who have been familiarized with the contents of
this manual.
Receipt and unpacking:
Unpack the device without damaging it and check the device type
corresponds to the one ordered. The packaging should always follow with the
device until this has been permanently mounted.
3.1 Intended use of the product
Environment:
Avoid direct sunlight, strong dust or heat, mechanical shocks and impacts; do not
expose the device to rain or strong humidity. If necessary, heating is excess of the
stated limits for ambient temperatures should be avoided by way of ventilation. The
device must be installed in pollution degree 2 or better.

3.2 Personnel qualification
Risk of injury due to insufficient qualification Improper handling can
lead to considerable personal injury and property damage.
The activities described in these operating instructions may only be
performed by qualified personnel with the following qualifications.
Keep unqualified personnel away from the hazardous areas.
For mounting and commissioning of the sensor, these persons must be familiar with
the applicable country-specific directives and standards, and have the appropriate
qualification. You must have knowledge of measurement and control technology, be
familiar with electrical circuits and be able to carry out the work described and recog-
nize possible hazards independently. Depending on the operating conditions, other
knowledge may also be required, e.g. about aggressive media.
3.3 Special hazards
Observe the country-specific regulations (e.g. standards) and, in the
case of special applications, observe the applicable standards and
directives (e.g. for hazardous media such as Acetylene, flammable
or toxic substances as well as refrigeration plants and compres-
sors).
If the relevant regulations are not observed, serious personal
injury and damage to property may result!
Electrostatic discharge (ESD) protection is required. Proper use of
grounded work surfaces and personal wrist straps is required when
working with open circuits (printed circuit boards) to prevent damage
to sensitive electronic components from electrostatic discharge.
There is danger to life from electric current. There is a immediate risk
of death if live parts are touched. Installation and mounting of
electrical equipment may only be carried out by qualified electricians.
When operating with a defective power supply unit (e.g. short-circuit
from mains voltage to output voltage), life-threatening voltages can
result at the device.
Residual media in devices that have been removed can be
hazardous to persons, the environmet and equipment. Sufficient
precautions must be taken. This device must not be used in safety or
emergency stop devices. Incorrect applications of the device can
lead to injuries. In case of a fault, aggressive media at extreme
temperatures and under high pressure or vacuum may be present at
the device.

4. Commissioning and operation
4.1 Before mounting
Check whether a completely assembled measuring transducer has
been supplied. Inspect the device for any transport damage that
may have occurred. If such damage ispresent, notify the carrier and
supplier immediately. Keep the packaging, as it provides optimum
protection during tranport. Make sure that the housing and the
connection contacts are not damaged.
4.2 Mounting / Installation / configuration
•Due to the extremely low power consumption, the units can be mounted side by
side without an air gap between them even at an ambient temperature of 60°C.
•Configuration, monitoring, 2-point process calibration and more are performed
with either the UMU-FD detachable displays.
•All programming can be password protected.
Calibration and adjustment
During calibration and adjustment, the measurement and connection of external vol-
tages must be carried out in accordance with this manual, and the technician must
use tools and instruments that are safe for this purpose.
Normal operation
The operating personnel may only set or operate the device if these are permanently
installed in control panels or similar in a justifiable manner so that the operation does
not involve any danger to life or material. I.e., there must be no danger from contact
and the device must be placed so that it can be easily operated.

5. Decomposition of the system UMU 100-A-B
First, disconnect dangerous voltage from the terminals.
The device is released from the DIN rail by loosening the lower catch.
When the front LED is red / display shows AO.ER
The device has been developed with a high level of safety. Therefore, a continuous
measurement of the output current takes place at the 4...20 mA output signal. When
the current is 0 mA, the device switches to error mode and the LED indicator lights
red. This function is not a standard option, but must be actively selected in the menu.
The error mode can only be reset by switching the power supply of the device off and
on again.
