1. DURTOX-X. Electrochemical technology detectors
DURTOX-X is an exproof detector using electrochemical technology for the detection of toxic gases and O2.
Communication formats
• RS485C addressable, 4 wire connection, compatible with EUROSONDELCO and SIEMENS
CC62P control panels. Up to 16 detectors can be connected in parallel on the same loop.
•4-20mA, 3 wire connection, compatible with any standard system provided with this type of input.
Applications
DURTOX-X exproofdetectorshavebeendesignedforenvironmentsinwhichtheformationofexplosiveatmospheres
due to gases or vapours is probable, and assure a high level of protection.
(Group of apparatus II – ATEX Directive Category 2)
Special features
• Provided with a 12bit microprocessor allowing total control over the sensor status..
• Thermal compensation that allows a correct response from each of the electrochemical sensors
when faced with temperature variations, except for DURTOX-X O2, which due to its systems does
not require such a feature.
• Self testing hardware.
• Digital filter based on variable samplings of the sensor average values
• Auto-Zero automatic adjustment This special feature monitors zero value in relation to sensor
response and electronics. The following protocol is used for this: Every 30 minutes an automatic
test is performed, if drift is +/- than 2% of the full scale, it will readjust itself to zero, otherwise it
will be shown as a readout.
• Other features accessiblewithfactorybasedmethodologyallowustocheckonthesensorremaining
useful life, date of manufacture, date of last calibration and serial number.
2. RELAY OUTPUT MODULE (optional)
The optional relay output for the RS485 models of DURTOX-X is programmed with the following default values:
Activated, instantaneous –no delay-
Alarm: 50ppm for CO, 10ppm for H2S, 25ppm for NH3, 5ppm for NO2, <18% for O2
Available gases Standard range* Installation height Area covered
Carbon monoxide CO 0-300ppm* 1,50 to 2m from floor 300 m2
Hydrogen sulfide H2S 0-100ppm / 0-200ppm* 1m from floor 150 m2
Ammonia NH30-100ppm*/0-1000ppm/0-5000ppm 30cm from ceiling 75 m2
Nitrogen dioxide NO20-20ppm* 1m from floor 200 m2
Oxygen O20-25% vol* 1,70 to 2m from floor 200 m2
* Ranges available with RS485C detectors compatible with EUROSONDELCO / SIEMENS CC62P

3. CONNECTIONS
IMPORTANT – Instructions regarding cable glands for ATEX detectors:
The user must ensure the cable is well anchored. The minimum torque setting applicable to the cap is 20 Nm.. Check
cable entry tightness after any maintenance operation: If cable has moved, tighten up the cap again. If tightening
isn’t possible, send the detector back to factory for cable gland replacement.
DURTOX-X with RS485C communication:

DURTOX-X with 4-20mA communication :
IMPORTANT: If the system where detectors are to be connected does not have 4-20mA inputs, but 0-5 or
0-10V DC tension inputs, a resistance must be connected between negative (-) and signal (s), on the receptor devi-
ce. Resistance value will depend on the detector power tension in accordance to the following table:

4. ADDRESSING RS485 DETECTORS
Before connecting DURTOX-X detectors to EUROSONDELCO or SIEMENS CC62P, they must be addressed. If
more than one detector is connected to the same loop, assign a number to each of them according to table 1.
Table 1- NUMBERING DETECTORS USING SW1 (addressing)
5. OPTICAL INDICATORS (internal LEDs): signals and functioning
RS485C models – installed in vertical module -
• Fast intermittent: during initialization and recognition of the loop by the module line.
• Periodic intermittent: normal functioning. Time between blinking, in seconds, will correspond with
the assigned number of the detector (1 to 16).
• 6-blink burst: Line failure. A-B communication cable is cut.
• 1 second cadence: failure or short circuit in the A-B communication lines. More than 5 minutes
have passed without the detector being able to communicate with the module line.
4-20mA models –installed in main module-
• LD1: indicates the detector operational status.
• LD2: this LED will turn on in case of any internal failure in the detector as well as to indicate a
positive or negative scale overflow.

6. TEST
Once connected, DURTOX-X begins to count a 60 second sensor stabilization time. During this time the 4-20mA
model will have a tension output of only 1,9mA, later increasing to 4mA.
Do not open these detectors while powered. Adjustments or calibrations of the installation are not allowed. Due to
the technology applied, these operations can only be carried out at the factory.
Perform a check-up test at least once a year using gas tester containers with the right composition for each gas.
Using any other means could poison or destroy the sensor and, therefore, the guarantee would be invalidated.
All detectors manufactured by DURAN ELECTRONICA are factory calibrated with the appropriate target gas.
Therefore, manipulation is neither required nor advisable once installed.
