Description
2.2 Functional description
2.2.1 Principle of operation of the DrägerSensor DD, LC
The DrägerSensor is a transducer for measuring the partial
pressure of flammable gases and vapors in ambient air.
It operates on the heat of combustion principle.
The ambient air to be monitored diffuses through the flame
arrestor in the sensor. The mixture of flammable gases and
vapors is burned catalytically on the heated measuring element
(pellistor). The oxygen required for combustion is taken from
the monitored ambient air (must be greater than 12 vol.%).
The measuring element receives additional warming from the
heat arising from the combustion. This warming causes
a change in the resistance of the measuring element which is
proportional to the concentration of the mixture of flamable
gases and vapors in the air being monitored.
In addition to the catalytically activated measuring element, the
sensor also has a compensating element. Both elements are
part of a Wheatstone bridge circuit. Consequently, environmental
influences such as changes in temperature or humidity are
almost completely compensated for.
The DrägerSensor LC includes additional processing and
amplification of the measuring signal. As a result, the sensor is
suitable for the measuring range 0 - 10 %LEL.
2.2.2 Principle of operation of the DrägerSensor IR
The DrägerSensor IR infrared gas sensor is a gas transmitter
for determining the concentration of gases and vapors in
ambient air. The measuring principle is based on the
concentration-dependent absorption of infrared radiation in the
measured gases.
The ambient air to be monitored diffuses through a sintered
body into the pressure-tight housing of a measurement
cuvette. The broadband light produced by the emitter passes
through the gas in the cuvette, is reflected from the cuvette
walls and is focused on the entrance window of a dual-element
detector. One channel of the detector measures the gas-
dependent light transmission of the cuvette (measuring
channel) and the other is used as the reference. The gas
concentration in the cuvette can be determined from the ratio
of the measured signal to the reference signal. The cuvette is
heated to prevent condensation of atmospheric humidity.
The calculation of the concentration is performed by internal
electronics and software. For the output signal, the gas sensor
emulates the half bridge of a catalytic bead sensor.
2.2.3 Contaminating gases for the DrägerSensor DD, LC
It may be necessary to check the calibration if the sensor has
been exposed for a long time to a high concentration of
flammable gases or vapors or the above-mentioned
contaminating substances.
2.3 Intended use
The Dräger Polytron 8200/8310 is an explosion proof device for
continuous monitoring of the concentration of gases and vapors
containing hydrocarbons. The housing for the device consists
of robust, non-corroding stainless steel or aluminum and is
suitable for indoor or outdoor applications. The unit can be
connected to a Dräger monitoring system or a programmable
logic controller (PLC) by means of a sealed conduit or an
appropriately approved cable gland. With the optionally
integrated relay module, the device can be operated without a
central controller (with additional local alarm signalling). The
device is designed for fixed installation and is approved for use
in potentially explosive atmospheres, see chapter 2.5 on
page 7.

{Detection range: 0 to 10 % LEL 2)
NOTICE
Certain substances in the atmosphere to be measured
can impair the sensitivity of the sensors.
a) Polymerizing substances such as acrylonitrile,
butadiene and styrene
b) Corrosive compunds such as halogenated
hydrocarbons (which release halogens such as
bromine, chlorine or fluorine on oxidation) and halogen
hydracids, as well as gaseous acidic compounds such
as sulfur dioxide and oxides of nitrogen.
c) Catalyst poisons such as sulfur and phosphorus
compounds, silicon compounds (particularly silicones)
and organometallic vapors. The sensors used work with
measuring elements (pellistors) that are poison-resistant
(PR) and thus have a longer life than conventional
sensors when catalyst poisons are present.
WARNING
Not tested in oxygen enriched atmospheres
(>21% O2). High off-scale readings may indicate an
explosive concentration.

Installation
3.2 Restrictions on the installation
zThe device requires a DC voltage between 10 and 30 V.
The minimum supply voltage of 10 V and the cross-section
of the conductors used determine the distance of the
device from the supply or the central controller
(see chapter 12 on page 28). The device is designed for
cables of sizes 12 to 24 AWG (0.2 to 2.5 mm2). Use
a three-wire, shielded cable as a minimum.
zThe device must not be subjected to any radiant heat
(e.g. direct sunlight) as this will result in a temperature rise
above the specified thresholds (see chapter 12 on
page 28). The use of a reflective screen is recommended.
zThe housing is weather resistant and suitable for outdoor
applications. The use of the optional splash guard is
recommended to protect the sensor from water and dust.
zThe device must be installed and operated in an
environment which conforms to the stated specifications
(see chapter 12 on page 28).
zTo insure proper operation of the device, the impedance of
the 4 to 20 mA signal loop must not exceed 500 ohms.
Depending on the operating voltage and according to the
application (e.g. HART operation), certain minimum
impedances must be adhered to (see chapter 3.3 on
page 8). The conductors for the power supply must have
an adequately low resistance to insure the correct supply
voltage at the device.
3.3 Impedance range of the signal loop
Devices with a HART interface can be operated with HART
communication or in HART Multidrop mode.
3.4 Mechanical installation
zUse the supplied drilling template for mounting on a wall.
zThe mounting surface should be even and free of sharp
edges.
zDräger recommends using M6 Allen bolts.
zThe openings must be readily accessible to the surrounding
atmosphere.
NOTICE
A dust cap can be fitted to the cable entry of the device.
This cap is only used for transport purposes and must
be removed before the device is connected to a sealed
conduit.

2 Calibration adapter
3 Test gas cylinder
4Hose
For DSIR only (see also Instructions for Use for
DrägerSensor IR)
1. Position the magnetic wand on the sensor button marked
with and hold it there for at least 5 seconds.
A negative value will be displayed for as long as the
magnetic wand is held on the button (e.g. -10 %LEL).
This will start the automatic zeroing of the sensor.
2. Remove the magnetic wand.
The sensor ends the automatic zeroing after approx.
30 seconds. A negative value (e.g. -10 %LEL) is displayed
again as confirmation.
After the zero-point calibration of the DrägerSensor IR,
the instrument should show 0 %LEL in the display. If this is not
the case, a zero-point calibration must be performed on the
instrument (see chapter 5.1.1 on page 14).
5.1.1 Zero point calibration
1. Select Calibration > Zero Calibration and confirm.
The Maintenance signal is transmitted.
The message Apply zero gas appears.
2. Apply zero gas (synthetic air or nitrogen) to the sensor.
3. Select Next and confirm.
The current value is displayed.
After the displayed value is stable:
4. Set the value to 0 and confirm.
The message Please wait… appears.
The actual value is displayed.
zActual value within the permissible range:
{Select Next and confirm.
{Shut off the test gas and remove the calibration adapter
from the sensor or disconnect the hose.
CAUTION
Danger to health! Do not inhale the test gas.
Observe the hazard information in the corresponding
safety data sheets. Provide venting into a fume
cupboard or outside the building.
Always calibrate the zero point first before the
sensitivity. Otherwise the calibration will be faulty!
NOTICE
Calibration is not possible if the date and time are not
set (see chapter 8.2.3 on page 19).
Dräger recommends calibrating devices with the gas
that is to be measured operationally. This method of
measured gas calibration is more accurate than a
surrogate gas calibration. A surrogate gas calibration
may only be performed as an alternative if a measured
gas calibration is not possible.

NOTICE
Ambient air can also be used instead of nitrogen or
synthetic air to zero the sensor, provided it is insured
that the ambient air contains no measured gas or any
other gas for which the sensor may exhibit cross-
sensitivity (see the details in the sensor data sheet).
In this case, neither a gas cylinder nor a calibration
adapter is required for the zero point calibration.

be changed.
4. Start the calibration with Next; Back to menu aborts the
calibration.
5. Feed the relevant calibration gas to the sensor at a flow
rate of 0.5 - 2.0 L/min.
{When the measured value is stable, the device performs
the calibration automatically.
{After a successful calibration, the measurement and
the message Value OK? are displayed
6. When the measurement is stable, shut off the calibration
gas and wait until the measurement is below any possible
alarm thresholds again.
zThe calibration is performed again with Redo.
zComplete the calibration with Accept value.
The device returns to the measurement mode.
NOTICE
Not all of the available sensors and gases support auto
calibration. If the function is not available, a manual
calibration must be performed.
WARNING
It must be insured that during the zero point calibration,
no measured gas is present in the supplied calibration
gas. Particularly with a fresh air calibration, Dräger
recommends performing a second, independent
measurement. Some sensors may only be calibrated
with synthetic air or nitrogen (observe the relevant
sensor data sheets).
NOTICE
After 10 minutes, without confirmation the device
reverts to measurement mode without performing
a calibration.

8.3 Communication settings
8.3.1 Settings for the HART interface (only for devices
with the optional HART interface)
This group contains the setting functions for the HART interface.
Setting the polling address
The polling address configures the device for analog operation
(4 to 20 mA) or multidrop operation. Analog operation (4 to
20 mA) is activated by setting the polling address to 0.
For multidrop operation the polling address must be
configured to a value between 1 and 15, which will result in the
analog interface being deactivated and set to a constant
current of approx. 1 mA. To allow the control unit to request the
Unique Identifier (unique HART address) with HART command
#0, all the devices on a line must be configured with different
polling addresses. It is advisable to choose a sequence
starting with 1 and incrementing continuously.
This setting corresponds to HART command #6 (Write Polling
Address).
1. Select Settings > Communication > HART interface >
Polling address and confirm.
2. Select the address line for the entry and confirm in order to
switch to the Change mode.
3. Set the polling address and confirm.
4. Select Confirm and confirm.
