* Ranges available with RS485C detectors compatible with EUROSONDELCO / SIEMENS CC62P

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 exproof detectors have been designed for environments in which the formation of explosive atmospheres 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 accessible with factory based methodology allow us to check on the sensor remaining 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 H

2

S, 25ppm for NH

, 5ppm for NO

2

, <18% for O

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 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 device. 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.

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.
