WARNING
The equipment is only approved for use in potentially
explosive atmospheres when using components
suitable for such areas, complete with test certificate.
Risk of explosion!
Devices or components for use in potentially explosive
atmospheres, which have been tested and approved
according to national, European or international Explosion
Protection Regulations, may only be used under the
conditions specified in the approval and with consideration
of the relevant legal regulations. The devices or
components may not be modified in any manner. The use
of faulty or incomplete parts is forbidden. The appropriate
regulations must be observed at all times when carrying
out repairs on these devices or components.

and highlight areas of the associated text that require a greater
awareness by the user. A definition of the meaning of each
icon is as follows:
WARNING
Indicates a potentially hazardous situation which, if not
avoided, could result in death or serious injury.
CAUTION
!
Indicates a potentially hazardous situation which, if not
avoided, could result in physical injury, or damage to
the product or environment. It may also be used to
alert against unsafe practices.

Indicates additional information on how to use
the product.
2 Intended use
The Dräger SAM 3100/SAM 3200 is an aspirator system for
continual intake of gas/air mixtures for a gas transmitter
(SAM 3100) or for two gas transmitters (SAM 3200), in order
to carry out measurements of toxic and/or explosive
substances in hard-to-access places.
In the event of insufficient process overpressure, a partial flow
of the process gas is siphoned off from the process using
a gas sampling pump with electric drive, or alternatively using
an ejector.
In order to separate solid particles from the gas flow,
the gas is passed across a filter.
The sample gas is passed to the flow meter with ring
initiator (for flow monitoring) via a 3/2-way spherical valve
(option for simplified feeding of test gas) and then flows into
the sample chamber of the sensor or sensors.
The air is either discharged to atmosphere or fed back
to the intake point by means of the air outlet on
the transmitter.
WARNING
During installation without return feed for the sample
gas back to the intake point, the sample gas should be
guided to a vent or outside. Risk of poisoning or
explosion! The return feed must not be pressurised.

4 Settings
4.1 Air quantity
The flow should be set according to the sensor type:
Transmitter with electrochemical sensor ~60 l/h
Transmitter with electrochemical sensor + IR transmitter
in series ~80 l/h
IR transmitter ~180 l/h
The flow should be matched to the circumstances in the system
as a whole.
4.2 Standard system without delivery unit
The sample air leaves the process with excess pressure!
The sample gas flow should be set to 60 l/h at the fine
regulating valve on the flow meter. The top of the ball is the
read mark for the scale.
Notice on handling: see the Instructions for Use for the
flow meter.
4.3 System with ejector unit
To function correctly, the regulating valve needs an input
pressure of 1 bar to 10 bar. The control range of the
regulating valve is 0.2 bar to 10 bar.
Setting the sample gas flow:
Open the fine regulating valve on the flow meter (turn anti-
clockwise to the stop, then 1 turn back).
Set the flow approximately at the regulating valve, then carry
out the fine regulation using the regulating valve on the
flow meter . The top of the ball is the read mark for the scale.
Notice on handling: see the Instructions for Use for the
flow meter and for the regulating valve.
4.4 System with gas sampling pump
The sample gas flow should be set to 60 l/h at the fine
regulating valve on the flow meter. The top of the ball is the
read mark for the scale.
Setting the sample gas flow:
Open the fine regulating valve on the flow meter (turn anti-
clockwise to the stop, then 1 turn back), set the flow
approximately at the bypass valve on the gas sampling
pump, then carry out the fine regulation using the
regulating valve on the flow meter. The top of the ball is the
read mark for the scale.
Notice on handling: see the Instructions for Use for the
flow meter and for the gas sampling pump.
Regulating valve (option)
Input pressure: 1 bar to 10 bar
Control range: 0.2 bar to 10 bar
3/2-way spherical valve (option)
Material: Stainless steel
WARNING
The equipment is only approved for use in potentially
explosive atmospheres when using components
suitable for such areas, complete with test certificate.
Risk of explosion!
Test certificates are included in the equipment documentation.
4.5 Circuit breaker (option)
The circuit breaker is delivered together with the aspirator
system as a separate item. Installation is carried out on site
by the operator in accordance with the assembly
instructions. Information is included in the documentation.
The circuit breaker makes it possible to monitor line breaks
and short circuits. Furthermore, the action of the relay can
be reversed by means of a switch. Settings should be
adjusted in accordance with the operator's requirements
during commissioning. Information is included in
the documentation.
Standard: Auxiliary power 24 V DC
Optional: Auxiliary power 230 V, 50 Hz
