Design
Design
The Dräger PIR 7000 is an infrared gas transmitter for the detection of flammable
hydrocarbons in the ambient air or in other suitable atmospheres.
The Dräger PIR 7200 is used for detecting carbon dioxide (CO2) in the ambient air or in other
suitable atmospheres.
The optical 4-beam technology ensures utmost signal stability for all models over long periods.
The gas transmitter is available with an M25 or a 3/4 inch NPT thread.
The Dräger PIR 7000 type 334 model provides comparable sensitivity in the measuring
range of the Lower Explosion Limit (LEL) for many gases and vapours containing
hydrocarbons such as methane, propane and ethylene.
The Dräger PIR 7000 type 340 model offers a high sensitivity for propane and alcanes of
greater length such as octane and nonane. This allows for more sensitive measurements and
alarm thresholds in the ppm range. Methane and ethylene are more weakly detectable with
this model (see “Cross-Sensitivities Dräger PIR 7000 Type 340” on page 76).
The Dräger PIR 7200 model is used to detect carbon dioxide (CO2) in a recommended
measuring range from 0 to 30 % vol. Lower concentrations are sensitively detected so that
even here a measuring range and corresponding alarm thresholds in the ppm range are
possible.
The gas transmitters are designed for use under the most adverse conditions (e. g. offshore).
A robust stainless steel housing protects the electronic and the optical components. Thus
only non-corrosive materials are subjected to the environment.
Due to the extensive range of accessories, the device can be adapted to almost any application.
Status indicator, flowcell and bump test adapter display different device statuses: normal
operation is indicated by a continuous green light and faults are indicated by a continuous
yellow light.
The device offers a fast and simple possibility for calibration of zero-point and sensitivity
(span). The magnetic wand is used to carry out corresponding calibration functions. The lights
support the calibration procedure with simple blink patterns.
Optionally the Dräger PIR 7000 is available with a HART® interface.
The Dräger PIR 7200 is equipped with the HART® interface in every version.
All models have a 4 to 20 mA current output (current source or current sink, automatically
detected) and a serial "one-wire" interface for the configuration via Dräger CC-Vision GDS
software.

Design
The software of the Dräger PIR 7000 type 334 contains linearised characteristics for the
gases methane, propane and ethylene. The software of the Dräger PIR 7000 type 340
contains linearised characteristics for the gases propane and methane. With the Dräger
CC-Vision GDS software, a software based on HART® DD/DTM or a HART® handheld
terminal, the gas transmitter can be configured to any of these gases without re-calibration. In
addition, the Dräger PIR 7000 offers an internal memory for up to ten substances with
individual linearised characteristics which can be loaded additionally (for more information,
please refer to page 46).
The Dräger PIR 7000 / Dräger PIR 7200 can be switched into "fast response mode" using
the Dräger CC-Vision GDS software (or a software based on HART® DD/DTM or a HART®
handheld terminal).
In standard configuration ("normal resonse mode") the measured value response time (t0...90)
is approx. four seconds when the measured gas concentration changes abruptly. In "fast
response mode" configuration, the measured value response time (t0...90) is less than one
second.

The Dräger PIR 7000 / Dräger PIR 7200 gas transmitter complies with the SIL standards
EN 61508 and EN 50402 and is SIL Level 2 certified.
Parameterisation of the Dräger PIR 7000 / Dräger PIR 7200 is an essential aspect of the
functional safety. Settings such as full-scale deflection, calibration values or the configuration
of the lower explosion limit (LEL) significantly influence the measured value output of the gas
transmitter.
To protect the gas transmitter parameterisation against unauthorised or accidental changes,
the access for device configuration can be locked (SIL lock). In this case, a parameterisation
of the device can only be carried out after a SIL passcode has been entered via Dräger
CC-Vision GDS Software, via HART® DD/DTM based software or via HART® handheld
terminal.

Assembly and Installation
Assembly and Installation
The gas transmitter installation may only be carried out by competent personnel (e.g. Dräger
Safety service personnel) under observation of the regulations applicable at the respective
location.
Assembly
—
—
—
—
—
Select the mounting location to achieve the maximum detection effect.
Free air circulation around the gas transmitter must not be hampered.
The mounting location of the gas transmitter must be selected as near as possible to the
location of the possible leakage place:
— to monitor gases or vapours that are lighter than air, the gas transmitter should be
installed above the possible leakage place.
— to monitor gases or vapours that are heavier than air, the gas transmitter should be
installed as near to the ground as possible.
Local air flow conditions must be considered. Install the gas transmitter at the location at
which you can expect the highest gas concentration.
Install the gas transmitter in a position where there is the lowest risk of mechanical damage.
The gas transmitter must be sufficiently accessible for maintenance. Observe a clearance
of approx. 20 cm (7.9 inch) around the gas transmitter!
Please observe the preferred orientation
— If a splash guard (part no. 68 11 911 or 68 11 912) is used then take care during assembly
to ensure that the status indicator lights are in a vertical line. The "Dräger" writing of the
splash guard must be able to be read horizontally. A maximum deviation of ±30 o from the
horizontal position is permissible.
—
Another assembly method is only permissible for gas transmitters without splash guard,
e.g. for applications in ducts – this increases the risk of contamination of the optical
surfaces.
NOTICE
Water and/or dirt on the optical surface areas may trip a warning or fault.

The gas transmitter is designed to be directly attached to a junction box.
For the model with M25 thread (IDS 011x) we recommend using the junction box Ex e
PIR 7000 (EAC 0000, part no. 68 11 898) – assembly: See page 39.
Furthermore, any approved junction box can be used that has an M25 (Ex e and Ex tD) or
3/4" NPT (Ex d or Explosion Proof and Ex tD) insertion opening (depending on the thread
of the gas transmitter) and connection terminals for at least three conductors (four
conductors when using the serial interface communication) and earth.
The junction box must be suitable for the mounting location and the application.
—
When mounting the junction box and gas transmitter, make sure that the junction box is not
subject to mechanical stress at the location of the connection.
● Close any unused cable entry openings at the junction box using approved plugs.
Dräger Safety recommends to use the mounting set PIR 7000 (part no. 68 11 648). The
mounting set is suited for attaching the gas transmitter to level and arched surface areas.
● Assembly: See page 25.
● As an alternative, the joint ring PIR 7000 (part no. 68 11 908) can be used the if the
mounting set is not used, see page 26.
— Sufficient distance to the wall, the ceiling and to the floor is ensured by using the PIR 7000
mounting set.
— In case of other assembly types, make sure that the distance between transmitter and wall,
ceiling or floor is above 4 cm (1.58 inch).
Orientation
The gas transmitter Dräger PIR 7000 / Dräger PIR 7200 is suited for wall, floor and ceiling
assembly.
The mounting set PIR 7000 can be mounted in offset positions of 90o, see page 25.
● Loosen the mounting set, rotate it according to the requirements and fasten the screws
again.

explosion protection
● If required: Mount the connecting union approved for the corresponding type of explosion
protection between the junction box and the gas transmitter.
For connection in the "increased safety" (Ex e) type of explosion protection in
conjunction with an approved, commercially available junction box
— The wall thickness of the junction box must be 4.2 mm to 12 mm at the mounting surface.
— The sealing surface towards the gas transmitter must be level and clean in the range from
28 mm to 32 mm diameter in order to ensure a flawless sealing by means of the provided
O-ring.
● Secure the M25 nut against self-loosening.
For connection in the "increased safety" (Ex e) type of explosion protection in conjunction with the junction box Ex e PIR 7000 (EAC 0000, part no. 68 11 648)

Assembly and Installation
Electrical Installation
Electrical installation to be done only by qualified professional observing all applicable
regulations. When installing the cabling, observe national regulations for the separation of
mains, low voltage and control current circuits (in Germany: VDE Regulations).
For hazardous area:
When installing, the entire wiring must meet currently valid national regulations
regarding the installation of electrical devices, and - if necessary - the national
regulations regarding the installation in potentially explosive atmospheres. In case of
doubt, the official responsible authorities are to be consulted prior to installation of the
device. Devices with a measuring function for explosion protection in accordance to
Directive 94/9/EC, Appendix II, 1.5.5 to 1.5.7, must be operated with a power supply
that do not transfer power interruptions on the primary side of up to 10 ms to the
secondary side.
—
Installation using three or more wire cable 0.5 mm 2 (AWG 20) to 2.5 mm 2 (AWG 13).
Recommendation: Shielded wire, shield braiding with an average coverage of ≥80 %.
Shielding connection: Recommended only at the central device. When operating with
HART® communication (HART ® operation), it may be necessary to connect the cable
shielding to the gas transmitter.
To ensure proper operation of the gas transmitter, the impedance of the 4 to 20 mA signal
loop must not exceed 500 ohms. Depending on the operating voltage and on the
application (e.g. HART ® operation), certain minimum impedances must be observed – see
table on page 20.
The power conductors must have a sufficiently low resistance to ensure the correct supply
voltage at the gas transmitter.
CAUTION
Do not connect the device to the power supply before the wiring is complete and has been
tested. This could damage the device.

Assembly and Installation
Current Source / Current Sink Operation
— The 4 to 20 mA signal output of the gas transmitter Dräger PIR 7000 / Dräger PIR 7200
can be switched both as current source (source operation) or as current sink (sink
operation). The gas transmitter detects whether the loop resistance is connected to (+) or
(–) and then automatically switches into current source operation or into current sink
operation.
NOTICE
The gas transmitter monitors the signal output current. If the loop resistance RS is not
present or is too high, the gas transmitter switches into fault and emits the fault signal.

Operation with Separation of Power Supply and Signal Lines
For gas transmitter operation with isolated power supply and signal lines to the central device,
the junction box Ex e PIR 7000 (68 11 898) provides an unused terminal (terminal no. 3).
Depending on the operating mode of the current output, a bridge between terminal number 2
and terminal number 3 (source operation) or between terminal number 1 and terminal number
3 (sink operation) should be installed in the junction box.
NOTICE
You have to use identical conductors of the same diameter and type for multi-wire
connection. Maximally two conductors per terminal (see page 13).

NOTICE
In the case of strong wind (wind speeds greater than 30 m/s, 11 Beaufort) there is a risk of
test gas mixing with the ambient air. This may lead to incorrect calibration gas
concentrations.
NOTICE
Detach the calibration adapter from the splash guard of the gas transmitter once the
calibration has been completed. The gas transmitter is not operational when the calibration
adapter is connected.
Remove calibration adapter:
● Gently pull on the hose connector of the calibration adapter; the calibration adapter snaps
out.
30
01723886_01.eps
Mounting:
1 Fit calibration adapter to splash guard of
gas transmitter until it snaps into place.
Make sure that the sealing surfaces
around the openings of the splash guard
are clean (clean before gassing, if
required). The insect guard PIR 7000
(part no. 6811609) does not need to be
removed for gassing.
— Calibrating the gas transmitter is only
possible when the supplied test gas
concentration in the measuring cuvette of
the gas transmitter is sufficiently stabile.
Therefore, the time required for
calibration is greatly dependent on the
gas flow, the hose diameter and the
length of the hose between test gas
container and calibration adapter.
— The gas rate of the test gas should be
between 0.5 and 2.0 L/min and never fall
short of 0.5 L/min.

Status Indicator PIR 7000 / 7200
(Part no. 68 11 625 / 68 11 920)
Intended use:
The status indicator contains light-conducting components for transmitting light signals to the
outer edge of the status indicator.
The gas transmitter features two status lights and provides the following information:
— Continuous green for indicating operational readiness
— Continuous yellow for displaying a fault or a warning
— Continuous yellow for displaying an error or a warning.
These light signals are arranged on two opposing sides of the status display.
NOTICE
The positioning of the light signals in relation to the upper side/underside of the gas
transmitter may change dependent on how the gas transmitter is mounted. Basically, the
colour assignment (yellow/green) is decisive, not the position of the light signals on the
status indicator.
Dräger Safety recommends that the labels (Power/Fault) are affixed in a such a way that the
outlet areas of the light signals are identified unambiguously.
01823886_01.eps

● Check system for sufficient gas-tightness.
If there are leaks, effluent gas may enter the measuring cuvette and lead to incorrect
measurements.
To protect the flowcell from dust and moisture:
● Fit air filter in the connected gas supply system.
● Cover flowcell connections with protective caps when not in use, or connect the inlet and
outlet e.g. with a hose connector.
Operation
● Prior to commissioning perform a zero-point and span calibration of the gas transmitter.
● Disable the alarm activation in the central device and/or start maintenance mode of gas
transmitter – see "Calibration", on page 57.
● Connect test gas supply to inlet of flowcell.
Recommended flow rate: 0.5 to 1.0 l/min.
Make sure no escaped gas can reach the remaining open IR measuring cuvette!
— If test gas flows through flowcell, the gas transmitter generates an analogue output signal
corresponding to the concentration.
— All alarm settings should be checked or deactivated during the test.
CAUTION
After the functional test: Purge flowcell using dry air or nitrogen to secure the zero-point.
Theory of operation
— Depending on the optical cuvette length of flowcell, the signal generated by the test gas
can be calculated as follows (example for Dräger PIR 7000 type 334, measured gas
methane):

Flowcell PIR 7000 Duct*)
(Part no. 68 11 945)
— In combination with the duct mount set PIR 7000, the PIR 7000 Duct flowcell is intended
for testing the function of the gas transmitter with high test gas concentration and external
test gas feed.
— Dräger Safety recommends a test gas flow of 0.5 to 1.0 L/min. The gas flow should be
monitored.
— For gas transmitters with or without splash guard.
— The performance characteristics of the gas transmitter are influenced by flowcell. A
calibration of zero-point and sensitivity (span) is therefore necessary after assembly or
disassembly of the flowcell!
— For further information, see page 32.
Bump Test Adapter PIR 7000 Duct*)
(Part no. 68 11 990)
— In combination with the duct mount set PIR 7000, the bump test adapter PIR 7000 Duct is
intended for testing the function of the gas transmitter (with splash guard) with a gas/air
mix in concentrations below the lower explosion limit (test gas).
— Since dilution effects (convection current, wind) may lead to concentrations lower than that
of the test gas in the measuring cuvette of the gas transmitter, the bump test adapter is not
generally suitable for calibration purposes.
Notices on operation:
● In order to minimise the effect of flow during function test, gassing of the gas transmitter
via the bump test adapter should be done with no less than 10 litre of test gas per minute.
Suitable pressure reducers should be used for this purpose.
● Operation with a bump test adapter does not influence the performance characteristics
and the approvals of the gas transmitter.
● For further information, see page 35.
The gas transmitter features two status lights and provides the following information:
— Continuous green for indicating operational readiness
— Continuous yellow for displaying a fault
— Flashing green/yellow for status messages during the calibration procedure.
These light signals are arranged on two opposing sides of the flowcell or the bump test
adapter.
NOTICE
The allocation of light signals relative to the upper / lower side of the gas transmitter may be
reversed depending on the assembly of the gas transmitter. Basically the colour allocation
(yellow/green) does not determine the position of the light signals on the status indicator.
Dräger Safety recommends proper attachment of the labels (Power/Fault) at the outlets of
the light signals.

Operational Characteristics
Operational Characteristics
Commissioning
The Dräger PIR 7000 / Dräger PIR 7200 gas transmitter is either set on delivery in
accordance to the details in the table on page 63 and page 64 or is built-to-order. The
essential settings of this configuration are specified on the configuration label on the device
or on the configuration certificate provided with the device (see page 8).
The device has been factory-calibrated, so after finishing the electrical and mechanical
installation, the device is ready to operate.
● To avoid false alarms, the alarm activation in the central device has to be disabled.
● Supply the system with power. The gas transmitter runs an internal self-test during which
the status indicator's lights flash alternately for a short time. During the first warm-up phase
of 60 seconds, the green status light is on and the yellow status light flashes. Operation
then subsequently begins using the configuration set on delivery.
● We recommend checking if the factory-preset calibration and configuration match with the
intended use of the gas transmitter. Due to national regulations, it may be necessary to run
a calibration of the zero-point and the sensitivity (span).
● After installation, Dräger Safety recommends checking the measured value output within
the configured measuring range (to the full-scale deflection) as well as checking if all
relevant alarms are triggered.
● Enable the alarm activation in the central device to put the system back to normal operating
mode.
— Wait for warm-up time to end.
The gas transmitter distinguishes between two warm-up phases:
Warm-up phase 1: Duration: 60 seconds. Green status light on, yellow status light flashes.
The gas transmitter is in maintenance mode and provides the configured
maintenance signal. No digital measured value is output via the serial
interface or the HART® interface.
Warm-up phase 2: Duration: 180 minutes. Green status light on. Gas transmitter is ready for
use. A corresponding digital warning is output via the serial and the
HART® interface. When warm-up phase 2 is finished, the warm-up phase
of the gas transmitter is typically completed. The gas transmitter then
reaches the specifications stated in the “Performance Characteristics
(typical values)” on page 73.

Configuration
Selecting a Measured Gas
The Dräger PIR 7000 / Dräger PIR 7200 gas transmitter supports the linearised and
temperature compensated display of several gases and vapours.
Before commissioning, the measured gas suitable for the application can be selected from
the gas library included in the device software. The configuration of the measured gas as well
as the measurement unit and measuring range, in which the gas concentration is indicated,
can be changed using the Dräger CC-Vision GDS Software as well as a HART® DD/DTM
based software or a HART® handheld terminal. The procedure is described in the
corresponding Instructions for Use.

The Dräger PIR 7000 gas library is prepared for up to ten additional measured gases. The
currently available selection of gases and vapours supported by the gas transmitter will be
supplied by Dräger Safety on request. The Dräger Safety service department can perform the
upload of additional measured gases.
Selection and Modification of LEL (Dräger PIR 7000 only)
Regionally different conversion factors may apply for the display of measured concentrations
in percent of the lower explosion limit LEL. The Dräger PIR 7000 gas transmitter allows you to
select one of three LEL categories which basically correspond with common explosion limits
in the USA (acc. to NIOSH), Europe (acc. to IEC 60079-20) and Germany (acc. to Brandes /
Möller – Sicherheitstechnische Kenngrößen, Band 1: Brennbare Flüssigkeiten und Gase).
The stored values are specified in the tables "Cross-Sensitivities" on page 75 to page 76.
In addition, individual conversion factors can be set based on the stored value of the selected
LEL category. In this case, the range is always limited to 75 % to 125 % of the value of the
selected LEL category.
Calibration Gas
For many gases and vapours, the calibration with the target substance is a major problem
because either a suitable calibration gas is not available, or because the vapour pressure of
the liquid is too low at the ambient temperature, or because the handling of a calibration
chamber in the field is problematic. A calibration using a substitute gas is always a tedious
process which can end with a significant linearity error.
The Dräger PIR 7000 gas transmitter allows a free selection of substitute gas calibrations with
any commercially available test gas (e. g. methane or propane) without further conversion,
provided this gas is listed in the gas library of the gas transmitter.
A calibration gas deviating from the selected measured gas is set for the calibration of
sensitivity (span). In calibration mode, the gas transmitter is first calibrated to the actual,
currently configured test gas concentration. Calibration data are then automatically converted
to the measured gas setting upon exiting the calibration mode. The specified measurement
accuracy for the selected measured gas is ensured by means of the specific gas parameters
stored in the gas transmitter.
All settings described above can be carried out using Dräger CC-Vision GDS Software as
well as using HART® DD/DTM based software or a HART® handheld terminal.

Beam Block Warning (patented by Dräger Safety)
Although the gas transmitter Dräger PIR 7000 / Dräger PIR 7200 is equipped with effective
facilities to protect the optic, in rugged environments the beam path may be subject to
contamination over time. In order to prevent interruptions of normal operation caused by heavy
contamination, a concept has been implemented which provides early warning of impending
contamination in the beam path in order to avoid immediate stop of normal operation. For this
purpose, the beam block warning can be activated.
In case the light intensity at the input of the optical measurement module falls below a critical
value due to increasing contamination so that the stability of the measurement signal can no
longer be guaranteed, the gas transmitter outputs a constant current of factory-preset 2 mA at
the analogue interface in case the beam block warning has been activated (configurable
between 0.7 and 3.6 mA). Since the remaining light intensity is still sufficiently high to ensure
a safe detection of alarm states above 15 %LEL (Dräger PIR 7000) or above 15 % of measuring range/15 FSD (Dräger PIR 7200), measurement of the current gas concentration continues in the background.
47
Operational Characteristics
Any arising risk caused by flammable gases or vapours or caused by carbon dioxide above a
concentration of 15 %LEL/15 %FSD will still be detected. For this purpose, the gas transmitter switches back to measuring mode and displays the measured value between 4 and 20 mA
either digitally or at the analogue output.
This procedure allows for any necessary service measures to be better scheduled and
controlled since no immediate intervention / cleaning is required.
In case the contamination should reach a degree which no longer allows for the safe detection
of gas concentrations above 15 %LEL/15 %FSD, a fault status will be emitted, either digitally
or with the associated factory-preset 1mA analogue signal (configurable between 0.7 and
3.6 mA). In this case the measurement readiness of the system is no longer guaranteed.
Warning
The Dräger PIR 7000 / Dräger PIR 7200 gas transmitter can be set to output a second
warning via 4 to 20 mA current interface. This is the device status "Warm-up 2".
If this warning is activated (e.g. via Dräger CC--Vision GDS Software), the current output is
switched to "fault signal" for approx. 0.7 seconds. This is repeated every 11 seconds. In the
factory-preset configuration of the gas transmitter, the warning is set to "inactive".

Operational Characteristics
Calibration Range Limits
During a calibration using the magnetic wand (part no. 45 43 428), the gas transmitter
provides information concerning the measured value of the device relative to the zero-point
and the set calibration gas concentration. This information is signalled as pulse sequences via
green status light as part of the zero-point and span calibration. This makes possible the
detection of a deviation of the zero-point and the sensitivity before a calibration. The deviations
are zero after calibration has been completed.

control system (Software Version 1.2 Polytron IR)
or
—
any HART® communication tool interpreting the HART ® commands selected for the
Dräger PIR 7000 / Dräger PIR 7200
or
—
Operating and display unit Dräger PEX 3300 / PEX 7300.
The gas transmitter periodically runs self tests for numerous internal functions. The gas
transmitter outputs a fault signal as soon as a deviation from normal operation is detected.
CAUTION
Gas transmitters with splash guard must be regularly checked for contamination of the
splash guard. Any contamination may cause an increase of the measured value response
time.
In case of contamination: Clean splash guard, replace if necessary.

Maintenance
Maintenance
Maintenance Intervals
Observe EN 50073 and respective national regulations.
Daily
● Visual inspection to determine readiness for operation – the green status light must be on.
While commissioning
● During the automatic self-test, check the function of the yellow and green status lights.
● Check zero-point calibration.
● Check the current interface and if required also the HART ® communication.
● Check measuring value output and alarm activation by applying suitable test gas.
Prior to the inspection: Disable the alarm activation in the central device. Re-activate it when
the inspection is over.
At regular intervals,
that are to be determined by the persons responsible for the gas detection system –
recommended after 6 months:
● Check the zero-point and sensitivity calibration (if necessary, temporarily disable the alarm
activation in the central device and re-activate it afterwards).
● Check signal transmission to central device and alarm activation.
● A calibration interval of more than 6 months is possible under the following conditions:
After an operation period of a maximum of six months, a check should be made of whether
an obstruction can occur in the gas entrance to the measuring cuvette within the given
application, e.g. due to dust, dirt, etc. If a restriction to the function caused by these effects
is excluded then the calibration interval can be prolonged – recommendation: Maximum
24 months.
Yearly
● Inspection by competent personnel.
The inspection intervals are to be individually determined with regard to safety regulations,
process control conditions and device-related requirements.
We strongly recommend that a service contract be signed with Dräger Safety to have them
handle repairs and maintenance.
52
Maintenance
Check the Measuring Cuvette of the Gas Transmitter and Clean if
Required
● To avoid false alarms during inspection, set the analogue output signal to maintenance
signal and/or ensure that the alarm activation in the central device is disabled.
● Remove the splash guard and, when required, any additional accessories from the gas
transmitter.
● Examine the air inlet and air outlet openings for contamination and damage.
● Check optical surface areas (mirror 1
1
2
04323886_01.eps
and window 2) and other accessories for
contamination, clean with water or alcohol and carefully dry with absorbent cotton or a smooth cloth.
Do not scratch the mirror or window!
Completely remove all cleaning agents!
Do not use sharp tools like scrapers or
screwdrivers!
● Install the splash guard and when required any other accessories to the gas transmitter.
● Re-activate the analogue output signal if it has been set to maintenance signal. And/or,
enable the alarm activation in the central device.

Calibration
General
The gas transmitter has been factory-calibrated for methane, propane and ethylene (Dräger
PIR 7000 type 334) or methane and propane (Dräger PIR 7000 type 340) or carbon dioxide
(Dräger PIR 7200). It can be useful and necessary to renew or to check the calibration.
Observe national instructions and regulations, if applicable.
The gas transmitter requires a 2-point calibration: A zero-point calibration and a sensitivity
calibration at a suitable point within the measuring range (span calibration).
Always use calibration adapter PIR 7000 (part no. 68 11 610).
Zero gas free of measurement gas must basically be used for zero-point calibration. Dräger
Safety recommends to use clean compressed air or nitrogen.
If calibration is performed on the Dräger PIR 7000 gas transmitter using ambient air (fresh
gas calibration), make sure that no measured gas and no other hydrocarbons are in the
ambient air during calibration.
The zero-point calibration of the Dräger PIR 7200 gas transmitter must always be carried out
using nitrogen or synthetic compressed air (without carbon dioxide traces, i.e. with a
percentage of <0.001 % vol.).
The sensitivity calibration can be performed with gas from the device's internal gas library. In
an ideal state of affairs (which is however not essential), the calibration gas is identical with
the measured gas.
CAUTION
The gas transmitter is factory-preset to a calibration gas concentration for the span
calibration, see table on page 63. Perform the span calibration with this concentration;
otherwise, the risk of getting higher measuring errors during operation increases. The
calibration gas concentration can also be found on the configuration label and – if
necessary – the calibration value can be changed using the Dräger CC-Vision GDS
Software, see “Calibration using the Dräger CC-Vision GDS Software” or the Instructions
for Use of the Dräger CC-Vision GDS.
Possible Ways of Calibration for the Dräger PIR 7000 / Dräger PIR 7200
— Locally using the magnetic wand (part no. 45 43 428).
— Using the Dräger CC-Vision GDS Software.
— Using a HART® handheld terminal (only devices with integrated HART ® interface).
Dependance of Calibration on Ambient Pressure
The gas transmitter provides a measurement signal which depends on the partial pressure of
the gas component to be measured. Variations of atmospheric pressure, or of absolute
pressure in dependance of the altitude of the site of operation, cause variations of the partial
pressure.
Dräger PIR 7000 [%LEL]
Measured value [%LEL]
Pi
The influence is: Dräger PIR 7200 [% vol.]
= Measured value [% vol.] X
1013 mbar
Pi = current pressure in the measuring cuvette
54
Maintenance
Example: If the gas transmitter Dräger PIR 7000 has been calibrated under normal air
pressure (1013 mbar), a pressure change to 900 mbar would result in the following change of
the measuring value:
900 mbar
50 %LEL X
= 44 %LEL
1013 mbar
(Remedy: Applying 50 %LEL calibration gas at 900 mbar pressure)
NOTICE
When delivered, the gas transmitter is calibrated with a reference pressure of 1013 mbar.
Deviations from this reference pressure can lead to deviating measured values at any
concentration.
Preparing Calibration
● Provide calibration gas.
For gas transmitters with mounted splash guard PIR 7000 / 7200:
● Push calibration adapter PIR 7000 onto the splash guard until it locks into place.
For gas transmitters with mounted flowcell PIR 7000 / 7200, bump test adapter PIR 7000 /
7200, process adapter PIR 7000 or process cuvette PIR 7000:
● Connect calibration gas feed directly to the flowcell, the bump test adapter, the process
adapter or the process cuvette.
Calibration Using the Magnetic Wand
The calibration can be performed directly at the gas transmitter using the magnetic wand (part
no. 45 43 428).
CAUTION
Always first calibrate the zero-point before the sensitivity (span).

Maintenance
NOTICE
If the status lights of the gas transmitter's status indicator, flowcell or bump test adapter are
not visible due to the type of installation (e.g. duct installation), the calibration can be
performed using Dräger CC-Vision GDS Software or (if the device is equipped with a
HART® interface) using a HART® handheld terminal.
After starting the calibration, if no further operation is done, the device automatically switches
to normal operation / measuring mode after some time without saving changed calibration
values. You can find additional information on this in the tables on page 57 and page 58,
column "Timeout".
NOTICE
In case of timeout, or when calibration is aborted, always make sure to disconnect the test
gas and to remove the calibration adapter. Otherwise, alarms can be triggered, or the
measurement readiness of the system is no longer guaranteed.

Maintenance
Fast Response Mode
In the factory-preset configuration ("normal response mode"), the gas transmitter provides a
minimum measured value response time of 4 seconds. The gas transmitter can be switched to
"fast response mode" using the Dräger CC-Vision GDS Software or (optional) with a software
based on HART® DD/DTM or a HART® handheld terminal. This can be useful when the
measured gas is fed via pump or when the gas transmitter is operated in ducts where fast
monitoring of gas concentration changes is required.
CAUTION
When "fast response mode" is set, the repeatability error increases by the factor 2. After
changing the response mode, it is absolutely necessary to perform a complete calibration.
Due to the system design, very fast gas changes could lead to increased measured values.
Remedy (if necessary): Reduce the gas exchange rate by reducing the flow rate at the process
cuvette or at the process adapter, and/or in the duct.
Disposing of the Device
From August 2005, regulations apply to the whole of the EC for the disposal of
electrical and electronic devices; these regulations are set in the EU Directive 2002/
96/EC and in national laws relating to this device.
Special collection and recycling possibilities have been established for private
households. However, since the device has not been registered for use in private
households, it cannot be disposed of as special household waste. For disposal, it can
be sent back to your national Dräger Safety Sales organisation; if you have any
questions requiring disposal, then please contact this location.

Faults, Cause and Remedy
Faults, Cause and Remedy
03623886_01.eps
The yellow status light signals errors or
faults of the gas transmitter. It is irrelevant
which error/fault has occurred. The current
output in the factory pre-set configuration is
<1.2 mA.
An output signal of 0 mA indicates an error
in the current loop or a defective device.
● Check current loop.
Remedy:
● Disassemble splash guard, check optical surfaces (mirror, window) for contamination and
clean if required, see “Check the Measuring Cuvette of the Gas Transmitter and Clean if
Required” on page 53.
● Calibrate zero-point, see “Zero-Point Calibration Dräger PIR 7000 / Dräger PIR 7200” on
page 57.
● Mount splash guard.
If the error persists:
● Check output circuit (load resistance) and power supply.
If the fault can not be rectified with these measures, the error is often a serious one. You can
use the Dräger CC-Vision GDS software to read out a detailed fault information.
● To do so, connect the gas transmitter via HART ® or the serial interface with the PC (see
page 63).
● Start Dräger CC-Vision GDS Software and read out the errors/error code.
● Contact Dräger Safety, if necessary.

Description of Design
Description of Design
The gas transmitter Dräger PIR 7000 / Dräger PIR 7200 is a measurement transducer to
measure the concentration of hydrocarbons / carbon dioxide in the atmosphere according to
the principle of absorption of infrared radiation.
The infrared technology differs from other sensing technologies by:
Clarity of reading for concentrations above the lower explosion limit (resp. up to 100 % vol.
carbon dioxide for Dräger PIR 7200), reduced maintenance efforts due to increased longterm stability, fault safety (Fail Safe), insensitivity against flow velocity, insensitivity against
polymerising and corrosive substances and catalyst poisons, unlimited measuring sensitivity in
oxygen deficient and oxygen free mixtures, no proof of ethine, hydrogen and carbon
disulphide.
The microprocessor technology allows for:
Detection of device faults and warning via status indicator and current output and/or digitally,
special calibration mode for suppressing the alarm triggering in the central device during
maintenance (one-man-calibration), individual linearisation of reading for all characterised
measured gases, temperature compensation, measuring range freely selectable.
The ambient air to be monitored gets into the measuring cuvette by diffusion, supported by a
thermally generated suction through the splash guard ("chimney effect").
An infrared radiation source generates a wideband modulated radiation (visible part
recognised from flashing). The radiation emerges from the stainless steel housing through a
sapphire window and passes through the measuring cuvette twice. The mirror reflects the
radiation which is guided into the optic module and to the detectors. The measuring cuvette is
heated to avoid condensation of the atmospheric humidity.
Compounds of hydrocarbons resp. carbon dioxide in the atmosphere lead to an absorption of
radiation at the measured wavelength and thus to a signal decrease of the measuring detector.
The zero-point stability is ensured by a reference detector which compensates for the effects
of contamination of mirror and window as well as potential variations of intensity of the infrared
radiation source.
A second internal radiation source allows for the compensation of thermal drift and ageing
processes of both detectors or sources. The combination of these two compensation
processes provides optimum signal stability.
