Terminology
The marking system for dete tor DEGA NSx-yL III LCD:
Gas detector DEGA NSx-yL III LCD
Series of detectors in potentially explosive atmospheres
Type of detected gas
Sensor type with linear output
Third generation product with new DEGA design
Versions with an LCD display
DEGA NSx-EL III LCD with an ele tro hemi al sensor
They operate on the principle of change of electrical parameters on the electrodes stored in electrolyte, due to
oxidation/reduction reactions of the detected gas on it's surface. These sensors have good selectivity and the ability to detect
very low concentrations of toxic gases.
DEGA NSx-CL III LCD with a atalyti sensor (Pelistor)
They operate on the principle of catalytic combustion - gas concentration is measured based on the amount of heat released
in a controlled combustion reaction. The reaction is supported by a suitable temperature and the pressence of a catalyst.
These sensors can be used to detect a broad range of flammable gases. The sensors are characterized by fast response,a long
lifetime and high stability. A minimum of 10 % of Oxygen in the air is required for it's proper function.
DEGA NSx-IL III LCD with an infrared sensor (NDIR)
Top quality scanning method. They operate on the principle of infrared spectroscopy. The sensors have excellent selecivity in
organic matter, do not require any oxygen in the atmoshpere and are resistant to catalyst poisons (sulfur and silicon

5
compounds) which cause a change of sensitivity of catalytic sensors. The sensors are characterized by high stability and a long
lifetime.
DEGA NSx-SL III LCD with a semi ondu tor sensor
They operate on the principle of changes in electrical conductivity of semiconductors by changing the concentration of the
detected gas. Their advatage is a long lifetime in a clean environment and a wide range of different types of gases and vapors.
Their disadvatage is their low selectivity - the sensor largly responds to other gases for which it is not calibrated.
DEGA NSx-PL III LCD PID with a PID – photoionization sensor
Typical photoionization detectors measure volatile organic compounds and other gases in concentrations from sub parts per
billion to 10 000 parts per million (ppm). The photoionization detector is an efficient and inexpensive detector for many gas
and vapor analytes. PIDs produce instantaneous readings, operate continuously, and are commonly used as detectors for gas
chromatography or as hand-held portable instruments. Hand-held, battery-operated versions are widely used in military,
industrial, and confined working facilities for health and safety. Their primary use is for monitoring possible worker exposure
to volatile organic compounds (VOCs) such as solvents, fuels, degreasers, plastics & their precursors, heat transfer fluids,
lubricants, etc. during manufacturing processes and waste handling.

Instalation, assembly and disassembly of the dete tor
Before assembling, read the valid instalation standarts EN 60079- 9- (Selection, instalation, use and maintenance of
detectors for combustible gases and oxygen) and EN 45544-4 (Guildelines for the selection, installation, use and maintenance
of detectors of toxic substances).
In explosive environments the electrical installation must be performed according to DIN EN 60079.14 (Electrical instalation in
hazardours areas)
Secure that the sensor is reachable by air. The detector must be in a free area with no obstacles in its way (furniture etc.)
Ensure that the input of the sensor cannot be polluted by layers of dust or other contamination.
1. Assembly of the dete tor
The detector consists of four parts - the body of the detector, the removable sensor and Ex „d“ cable glands.
Detector assembly procedure is as follows:
a) Disassemble the detector using four screws with an internal hexagon of 5 mm.
b) Disconnect the LCD from the motherboard.
c) Mount the detector on a flat surface using four 6 mm dowels to a height above the floor according to the
specification of the detected substance with the gas inlet facing downwards.
d) Pass the cable through the gland.
e) Connect the cabling to the detector terminal board according to the chapters "connection of the detector to
control panels". It is only permitted to use an Ex "d" gland with an M 0x1.5 thread.
f) Interconnect using M4 grounding screws. A CUPAL washer must be used.
g) Connect the LCD.
h) Assemble the detector using four screws with an internal hexagon of 5 mm.
2. Replacement of the sensor module
This activity must not be performed when the detector is energized.
In case of need to replace the sensor module with a new piece, unscrew and remove the
cover. Disconnect the sensor module cable from the PCB (1), loosen the sink screw ( ) and
unscrew the steel cylinder with the sensor (3). Screw the new sensor module, retain it
with the sink screw and connect the cable to the PCB. Finally, mount the cover and
connect to the power supply.
3. Replacement of the battery
The battery lifetime in the
sensor is approximately 5 years. After
this time some functions of the
detector may not work properly. Remove the battery from the holder and replace it with one of the
recommended types. Replacing the battery in the transmitter, which is not connected to the power,
will erase the internal clock.

4. Connecting the detector via current loop to the controler DEG UP II/DEG UP III
Connect one detector to each channel of the controler as shown in the picture below
5. Connecting the sensor via RS485 to the controller DEG UK III/DEG UP III/DEG UD III
6. Installation of wiring for RS485
Wiring must be installed using bus topology and in compliance with the RS485 policy.
The maximum number of connected transmitters per controller channel is 16 (may be less depending on the configuration of
the controller), while the total length of the controller (electrical distance between the controller and the last transmitter)
should not exceed 400 meters.
Sele ting the appropriate type of able depends on the fire report and the proto ol for determining external influen es.
7. Setting the RS485 adress of the detector
Each detector must have a unique adr
ess within the entire bus, otherwise there will be communication
collisions and malfunctions.
The detector adress can either be set internally using the DegaConfig program or using the DIP switch
on the PCB.
If the position 6 (labeled ADD) is in the ON position, then the adress according to the setting of pins 1-5
is considered. Otherwise the adress set in DegaConfig is considered.
The adress can be set from range 1-31 using binary values. A table with DIP settings for individual
adresses is listed in the attachment "Chart for setting the detector adress"
8. Terminating resistor
According to the RS48
5 specifications, the last device on the bus must be ending with a terminating
resistor 1 0R. Plug a jumper on the JP connector of the last device on the bus to include the 1 0R
terminating resistor. In the default configuaration, the jumper connector is not plugged.

8
9. Communication protocol switch DEG /MODBUS
Plugging a jumper in the JP1 connector will swtich from the DEGA communication protocol to the
MODBUS communication protocol.
Dete tor fun tions
The detector's motherboard is equipped by status LEDs, which help in detecting problems during the installation.
LED „POW“ shines at correct power
LED „TxD“ flashes when transmitting a packet via RS485
LED „RxD“ flashes when a packet is correctly recieved via RS485
LED „ERR“ shines/flashes in case of malfunction or substandart situations
1. Turning on the detector
After turning on the power the LED "POW" starts shining and the LED "ERR" starts flashing, indicating a forming sequence of
the sensor and automatic testing procedures, which can take up to 180 s depending on the sensor used. The output of the
current loop is 1 mA. During this sequence, testing of internal electronics and stabilization of the sensor in order to eliminate
false alarms after turning on, is taking place. At this time, the display only shows the time to the beginning of the
measurement loop.
After completion of the formation, a 4 mA current begins to flow on the output of the current loop and the detector starts
working according to it's settings.
2. Gas detection
The detector continuously measures the detected gas concentration in the atmoshpere and converts it's current value into a
4- 0 mA signal or transmits it's value to the evaluation unit via DEGA/MOBUS protocol.
3. Malfunction
In case of malfunction the LCD displays the measured concentration, an error code and a key symbol . On the PCB this
condition is indicated by the yellow „ERR“ LED. The meaning of each error code is included in the attachment "Table of error
codes"
4. Monitoring the calibration periods
The detector continuously checks the calibration validity of the connected sensor.
After 1 months since the last calibration (Max. calibration interval) the LED "ERR" starts flashing and an inscription
starts flashing on the LCD display. The connected sensor must be calibrated immediately. The detector will
transmit the information about the ending calibration via current loop. The transmission will be the following:
10 s transmitting a 4- 0 mA signal informing about the actual gas concentration following a 1 second interval of mA current.
5. Reading the record of measured concentrations and alarms
The detector periodically after 60 s stores the current detected concentration into it's internal memory. The internal memory
retains data from the last 64 60 measurements (cca 44 days). In order to read this information, the program DegaConfig is
required. Refer to the DegaConfig program instruction.

To maintain proper operation of the detector it is neccesery to respect the fact, that step changes of humidity, condensation
or rapid changes of pressure can cause incorrect indication of the measured value. Each sensing technology is suited for
different methods of application, which is described below. All sensors are characterized by a smaller or larger cross-sensitivity
to other gases than those which are set. Therefore before processing project documentation we recommend to have the air in
the deployment area of the detection system analyzed.
a) atalyti sensors: Trace amount of vapors of silicon compounds and sulfur compounds cause a permanent loss of sensitivity,
which requires recalibration or replacement of the sensor. Longterm crossing of the measuring range causes a decrease in
sensitivity. In case of an atmoshpere having an oxygen content of less than 17 %, there will be an underestimaton of the
measured value. In case of an atmoshpere having an oxygen content of more than 5 %, there will be an overestimation of the
measured value.
b) ele tro hemi al sensors: Constant exposure to toxic gases or short-term exposure to gases, which greatly exceed the
maximum range of the sensor, can damage the electrochemical sensor, which requires recalibration or replacement. High
temperature along with low relative humidity have a negative effect on the sensor's lifetime. In case of an atmoshpere having
an oxygen content of less than 1 % for longer than 1 hour, there will be an underestimation of the measured value.
c) infrared sensors: Vapor acids and alkalis can etch the optical system and distort the measurements. A check or a calibration
may be neccesery.
d) semi ondu tor sensors: Short-term exposure to gases or vapors of organic solvents, which greatly exceed the maximum
range of the sensor, may damage the sensor and a recalibration or replacement may be required. In case of an atmoshpere
having na oxygen content of less than 18 %, there will be an underestimation of the measured value.
e) photoionization sensors: the UV lamp or sensor must be replaced regularly, its clogging may cause loss of signal.
2. Operation
To maintain proper operation of the detector it is neccesery to respect the fact, that the presence of certain concentrations of
gases or vapors, other than those for which the sensor is set, can cause an alarm, even if the concentration of the gas does not
exceed the set level. Given the range of disturbing gases or vapors (diluents, exhaust gases, vapors of organic substances,
disinfectants, etc.) a generally allowable concentration of interfering gases can not be determined. Data on cross-sensitivity to
certail gases are included at the apporpriate sensors. Therefore before processing project documentation we recommend to
have the air in the deployment area of the detection system analyzed .
3. Operation/Maintenance
In case of contamination the surface can be cleaned with a slightly moistened cloth.
The seonsors have a different lifetime depending on the sensing technology used, and environmental conditions.
Characteristics of the sensors vary over time. Therefore it is required to perform regular checks and calibrations, which can be
done in two ways:
a) 1 x every six months carry out a „ alibration“ and fun tional ontrol - adjust the sesitivity of the sensor using
calibration gas and check the functionality of the system. The exact interval depends on the purity of the environment,
required accuracy and the occurrance of disturbing gases in the atmoshpere .
b) 1 x every twelve months carry out a „ alibration“ - adjust the sesitivity of the sensor using calibration gas and check the
functionality of the system. The exact interval depends on the purity of the environment, required accuracy and the
occurrance of disturbing gases in the atmoshpere. Also carry out a „fun tional ontrol" 1 x every three months -
checking the function of the entire detection system using a test gas, which does not exceed the range of the sensor.
We recommend using gas intended for laboratory use .
For the „fun tional ontrol“ do not use means for testing fire alarm dete tors!
Perform calibration only at certified service centers with a valid certificate of competence or the manufacturer.
