Installing the Gas Transmitter
Installing the Gas Transmitter
Only trained service personnel (e.g. of Dräger Safety) may install the gas transmitter
under observation of relevant regulations.
Installation and commissioning are described in the "Dräger PIR 3000 Installation
Instructions" which are supplied with the gas transmitter.
Mounting Location
The protecting effect of the gas transmitter depends on the selection of the mounting location. By taking the site's air flow conditions into account, the best possible
mounting location should be chosen as close as possible to where a decisively
noticeable rise in gas concentration can be expected in case of a leakage, i. e.
— as close as possible to the potential leakage place
— when monitoring gases and vapours which are lighter than air:
above the potential leakage place
— when monitoring gases and vapours which are heavier than air:
near to ground.
In addition, it must be assured that:
— the air circulation in the gas transmitter vicinity is not hindered
— the danger of mechanical damage is reduced as far as possible
— the gas transmitter is sufficiently accessible for maintenance purposes. Especially
the configuration via magnetic pin requires a clearance of approx. 20 cm around
at least half of the sensor perimeter.
The gas transmitter can be mounted horizontally as well as vertically.
Mechanical Installation
Terminal box
The gas transmitter is designed to be directly attached to a terminal box.
Approved connector boxes of the following makes are available as gas transmitter
accessories: EEx d (explosion proof, 3/4" NPT) and EEx e (increased safety, M25) (see "Order List" on page 28).
● To maintain the housing protection class, the enclosed O-ring seal must be used
for an EEx e-type explosion protection connection.
Use a thread locking adhesive, e.g. Loctite® to prevent the M25 nut (torque of
15 Nm ±3 Nm) from self-loosening.
● Use approved plugs to close any unused cable entry openings at the terminal box.

Splash Guard and Calibration Adapter
We recommend using the supplied accessories - splash guard (1) and calibration
adapter (2) - to increase protection against water jets and contamination.
The splash guard is held by a fixture provided with screw-thread, which is also used
as calibration adapter.
Make sure that the calibration adapter is correctly seated. To this end, manually
tighten the calibration adapter to a point where the sealing line leaves a permanent
mark on the splash guard.

Installing the Gas Transmitter
Gas Exposure / Process Adapter (see "Accessories/Spare parts" on page 28)
For continuous flow operation of the gas transmitter, the calibration adapter can be
replaced with an optional gas exposure / process adapter.
— Suitable for flow rates between 1 and 3 L/min.
— Use external pump to ensure gas flow.
— External flow monitoring required.
— Also suitable for calibration gas application.

Assembly:
● Unscrew the calibration adapter from the gas transmitter. While doing so, leave
splash guard on the gas transmitter.
● Screw gas exposure / process adapter onto the gas transmitter and tighten firmly
by hand.
● Check the gas-carrying system for leaks, e.g. with a soap bubble test.
Dirt Deflector (see "Accessories/Spare parts" on page 28)
Instead of the calibration adapter, a double-walled dirt deflector can optionally be fitted to the gas transmitter. This is recommended for locations with a high rate of contaminations through salt crusts, oil films, resin or similar substances. In addition to
the dirt deflector, the use of a splash guard is strongly recommended.
● Also suitable for calibration gas application.

Installing the Gas Transmitter
Electrical Installation
The entire wiring must correspond with applicable local regulations concerning the installation of electrical devices in potentially
explosive atmospheres. In case of doubt, consult the responsible authorities before installing the device.
We recommend a three-core, screened connection cable (mesh wire shield with a shielding factor of ≥80 %).
Attention:
Earth leakages on two phases can cause EMC problems. To avoid these problems, the cable screen may only be connected to earth potential on one side (either at the central unit or at the gas transmitter). In most cases, connecting the
cable screen to the PE terminal of the terminal box has proven to work better than connecting it to the central device.
● If the corresponding connection is available:
Electrically connect the terminal box to earth.
● For installation in protection pipe: cast protection pipe seals and allow to harden.
● Do not connect gas transmitter and power supply before the wiring has been installed and tested.

RI
Installing the Gas Transmitter
— The leads between central device and gas transmitter must have a sufficiently low
resistance to ensure the correct supply voltage at the gas transmitter. The maximum resistance per core is calculated as follows:
R = 2.5 x UC – 25
with
R: maximum resistance per core
UC: voltage supplied by central device in volts (usually depends on the
supply voltage of the central device)
Example: With UC = 24 V, the result is a maximum resistance per core of R = 35 Ω.
With cable lengths per core of 1000 m, the resistance per unit length
R’ = 35 Ω/1000 m = 35 Ω/km may not be exceeded.
NOTICE:
Cable resistance deviations caused by temperature influences, transition
resistances of terminals, etc. can also contribute to the fact that the calculated cable length can not be fully used.
— The maximum resistance of the loop RI (sum of the internal resistance of the central device and of the cable resistance of the signal line) depends on the transmitter supply voltage as described below:

self check (10 seconds), then automatically uses the factory-preset calibration
(see page 11) and gas category.
For the duration of the self test, a signal of 1 mA is issued.
Wait for the running-in period of one minute to expire. No settings can be changed
at the gas transmitter during this period. The gas transmitter will emit a 1 mA signal for the duration of the running-in period.
Check signal transmission and adjust if required (see "Checking the signal transmission, checking the alarm trigger and displaying the gas category" on page 17).
Check setting of the gas category for the intended use. If required, set the gas
category (see "Changing the gas category " on page 18).
Check the calibration of the gas warning system (see "Calibration" on page 11).
Reactivate the alarm call to put the system back to normal operating state.
NOTICE:
To prevent moisture condensation on the optic surfaces of the device, parts of
the transmitter housing are heated from the inside. This can increase the
surface temperature by approx. 5 oC.

Operational Characteristics
Operational Characteristics
The gas transmitter generates an output signal which is proportional to the measured gas concentration. The factor of proportionality between displayed value and
the measured gas concentration is determined by the span calibration of the gas
transmitter (see "Manual Span Calibration of the Output Signal." on page 15).
The gas transmitter regularly runs self tests for numerous internal functions. As soon
as a divergence from normal operation is detected, the device will issue a fault message.

Calibration
A functional check and - if necessary - a calibration must be carried out regularly for
gas warning systems (see page 20, Maintenance).
Zero gas and test gas are to be applied for functional check and calibration of the
infrared gas transmitter Dräger PIR 3000. To this end, the gas is applied either with
— the calibration adapter in connection with the splash guard (see page 5, part of
the scope of delivery) or
— the gas exposure / process adapter (see page 6 and order list) or
— the dirt deflector in connection with the splash guard (see order list).
The required gas flow rate for functional check and calibration is as follows:
— 0.5 to 1 L/min. for the calibration adapter with splash guard and the dirt deflector
with splash guard in closed rooms at wind speeds up to 5 m/s (3 Beaufort),
— 1 to 2 L/min. for the calibration adapter with splash guard and the dirt deflector
with splash guard at wind speeds up to 27 m/s (10 Beaufort),
— 0.5 to 3 L/min. for the gas exposure / process adapter.
Make sure that the calibration adapter is correctly seated. To this end, manually
tighten the calibration adapter to a point where the sealing line leaves a permanent
mark on the splash guard.
Nitrogen, synthetic air or fresh air (hydrocarbon content <50 ppm) can be used for
zero point calibration.
11
Operational Characteristics
Commercially available calibration gas can be used to calibrate the respective gas
category (methane, propane, ethylene). The highest accuracy is achieved using test
gas concentrations of 40 to 70 percent of the measurement span.
The infrared gas transmitter Dräger PIR 3000 can also be used to measure other
gases than mentioned above. For detailed information, refer to "Substitute Gas Calibration" on page 16.
● Select the measured gas in the corresponding table and determine the corre-
sponding gas category.
● Set the gas transmitter to the determined gas category.
Where possible, calibration gas should match with the measured gas for span calibration. In exceptional cases, span calibration can be carried out using a suitable
substitute gas and the associated calibration factor. The suitable substitute gas as
well as the associated calibration factor is shown in the table "Substitute Gas Calibration" on page 16.
● Select the substitute gas (gas category) and the calibration factor in table "Substi-
tute Gas Calibration" on page 16.
● Multiply the concentration of the substitute gas by the calibration factor to get the
gas concentration to be set.
Example:
Measured gas:
Gas category:
Calibration factor:
Span gas concentration:
Setting:

Propane (see table "Substitute Gas Calibration",
page 16)
1.8 (in table "Substitute Gas Calibration", page 16)

40 %LEL x 1.8 (calibration factor) = 72 %LEL
CAUTION:
Never inhale test gas. Danger to health!
Observe the safety information in the corresponding safety data sheets.
Ensure that gases are vented or otherwise guided outside the building.

Operational Characteristics
Checking the Signal Transmission, Checking the Alarm Trigger and Displaying
the Gas Category
The gas transmitter can create an output signal of 80 % of the full scale value, even
without exposure to test gas. This 80% signal can be used to
— check the signal transmission of the central device,
— match central device and sensor signal,
— check the alarm triggering of the gas warning system.
After issuing the 80% signal, the gas category set at the gas transmitter is displayed
before the gas transmitter returns to normal operation.
● De-energising the alarm activation of the central device (not during alarm testing).
● Expose the gas transmitter to nitrogen, synthetic air, and/or fresh air via calibra-

and remains there for as long as the magnetic pin is held against it. At the same
time, a zerosetting of the optical measuring unit is carried out automatically.
● Remove the magnetic pin. After 30 seconds, the device exits the automatic zerosetting routine. As confirmation of the automatic zerosetting, the output signal
changes back to the span gas signal (3 mA). This signal is indicated for the same
period of time as when starting the automatic zerosetting routine. After that, the
output signal of the gas transmitter changes to 4 mA (0% signal).
● Check the display of the central device: set point 0 %LEL.
● If required, manually set the zero point at the gas transmitter to a display of 0

Operational Characteristics
— This signal is maintained for 30 seconds. The gas transmitter will then switch back
to normal operation.
— The central device display now matches the output signal of the gas transmitter.
ATTENTION:
Using the 80% signal to match central device and transmitter signal without
test gas is no replacement for the span calibration of the gas warning system.
Changing the gas category
The gas transmitter supports the linearized and temperature compensated display of
a wide spectrum of gases and vapours. Depending on the measured gas, you can
select one of the three gas categories "methane", "propane" or "ethylene" stored in
the software. A table which allocates a row of checked gases and vapours is available in the table "Substitute Gas Calibration" on page 16.
Changing the gas category is only possible under the following conditions:
— The device was less was started up less than an hour ago.
— The last zero calibration of the gas transmitter was less than an hour ago.
— The gas concentration measured by the device is below 10% LEL (expose to zero
gas if necessary).
To change the gas category of commissioned gas transmitters, interrupt the power
supply for a short period of time, wait for the running-in period of one minute to
expire, and then carry out an automatic zero calibration (see "Automatic Zero Calibration" on page 13).
Then:
● Deactivate alarm activation of the central device.
● Place the magnetic pin onto the transmitter surface area marked by the "
S "
icon (within the black frame) and hold it there.
After ten seconds, the output signal of the gas transmitter changes to 16.8 mA
(80% signal) and remains there for as long as the magnetic pin is held against it.

This signal is maintained for 30 seconds. Within this period of time, the magnetic pin
can be placed upon the area marked by the " S " icon to select the next gas listed
in the table. In the process, the output signal of the gas transmitter changes to the
value which corresponds with the newly selected value which corresponds with the
gas category.
The gas transmitter returns to normal operation if no further entry with the magnetic
pin is performed for 30 seconds.
● Check span calibration (see page 15).
● Reactivate alarm activation of the central device.

Maintenance
Maintenance
Regular intervals
are to be determined for the following tasks by the persons responsible for the gas
warning system while taking local regulations into account:
● Visual inspection to look for damage and contamination. Special attention is required for gas entrance to the gas transmitter. Anything that blocks the gas entrance to the transmitter, e.g. dirt, ice, precipitation, etc., can prolong the response
times or even completely disable the gas transmitter. Recommended inspection
interval: 3 months.
● Visual inspection of the splash guard. If required, dismount gas exposure / process adapter and/or dirt deflector. Clean or replace damaged splash guard.
● Visual inspection of gas exposure / process adapter. Clean or replace damaged
gas exposure / process adapter.
● Visual inspection of the dirt deflector. Clean or replace damaged dirt deflector.
● Check signal transmission and adjust if required (see "Checking the signal transmission, checking the alarm trigger and displaying the gas category" on page 13).
● Check the calibration of the gas warning system (see "Calibration" on page 9).
Recommended calibration interval: 6 months.
Extending the maintenance intervals is possible if local conditions are taken into
account, and if the recommended maintenance intervals require cleaning, maintenance or setup work. However, we do not recommend maintenance intervals that are
longer than 12 months.
Yearly
Inspection by competent personnel. The inspection intervals are to be individually
determined with regard to safety regulations, process control conditions and devicerelated requirements. We strongly recommend that a service contract be signed with
Dräger Safety to have them handle repairs and maintenance.

Description of Design
Description of Design
The Dräger PIR 3000 infrared gas transmitter is a gas transmitter designed to determine the concentration of gases and vapours in the ambient air. The principle of
measurement is based on the concentration-dependent absorption of infrared radiation in measured gases.
The monitored ambient air diffuses through sintered material into the flameproof
housing of a measuring cuvette. The broadband light emitted by the radiator passes
through the gas in the cuvette and is reflected by the cuvette walls from where it is
directed towards the inlet window of a dual element detector. One channel of the
detector measures the gas-dependent light transmission of the cuvette (measuring
channel), the other channel is used as reference. The ratio between measuring and
reference signal is used to determine the gas concentration in the cuvette. The
cuvette is heated to avoid condensation of the atmosphere's moisture content.
Internal electronics and software are used to calculate the concentration. The gas
transmitter sends a standard 4 to 20 mA output signal.
Due to its robust design and the measuring method, the gas transmitter has long
maintenance and calibration intervals (see "Maintenance" on page 20). A gas sensitivity drift is very unlikely due to the infrared-optical principle of measurement and in
addition, the zero point stability is enhanced by an automatic tracking system.
