4 │1Introduction
Explosion protection
●Do not operate the device in oxygen-enriched atmospheres,
otherwise the device will not be explosion-proof.
●The device must not be stored or operated in explosive envi-
ronments if there is a chance of strong electrostatic charges
occurring (e.g. from fast moving particles, hydraulically pro-
pelled liquids, pneumatically extracted dust or materials, in
electrostatic coating processes).
Maintenance
●Perform device inspection and adjustment only in well venti-
lated rooms or outdoors.
●Handle test gases in a professional manner.
Sensors
●Have sensors replaced by SEWERIN Service when their ser-
vice life has expired.
● SEWERIN recommends: Perform a device inspection when
the device has been exposed to gas concentrations above the
end of measuring range.
Special environments
● Substances containing silicone, and silicone vapours, can con-
taminate the sensors.
− Do not allow the device to come into contact with substances
containing silicone.
−Use the device only in a silicone-free environment.
● The device complies with the requirements of Directive
2014/30/EU (EMC). When using the product close to devices

10 │2Productdescription
Technical information about the sensors, including their meas-
urement ranges, can be found in section 9.2.
Information about electrochemical sensors
Very high gas concentrations can reduce the lifetime of electro-
chemical sensors.
Information about semiconductor sensors and catalytic
combustion sensors
Thesesensorsaresensitivetoexternalinuences.
− Oxygen-decientatmospherescanreducethesensitivityofthe
sensor(sensorsu󰀨ocation).
−Gaseous components of silicones, oils and phosphate esters
etc. can irreversibly damage the sensor.
−Contamination of the measuring environment with halogens,
burnt neoprene, PVC, trichloroethylene etc. will also reduce
the sensitivity of the sensor. However, the sensor can usually
regenerate itself during further operation.

2.3.2 Gas types
By default the device is set up for gas type methane CH4.
However,thesensorsttedtoadeviceasstandard(section 2.3.1)
can be set up for other gas types or for additional gas types.
The following gas types can be set up:
Gas type PM 580 PM 550 PM 500 PM 400
CH4× × × ×
C3H8o o o o
C9H20 – – – o
C2H2– – – o
H2– – – o
JFuel – – – o
× as standard, o optional, – not possible
The gas types can be set up:
−when the device is purchased
−subsequently using GasCom software1
You can switch between all gas types for which a device is set
up during operation (section 3.7).
2.3.3 Visual and audible signals
2.3.3.1 Overview
The device can emit the following signals:
●visual signal (via the signal light)
●audible signal (via the buzzer)
The two signal types are displayed together.
1The new gas type is available in the device only when an adjustment has
been performed after setting up.

12 │2Productdescription
Signals are emitted at:
●Alarm
●Error (error message)
●Device inspection or inspection due2
●Warning, information
● Switchdeviceonando󰀨
There are also signals as:
●Operating signal
●concentration-dependent signal
2.3.3.2 Alarm signals
Warning alarms are emitted if the concentration of one or more
gases exceeds certain limit values (alarm thresholds).
AWARNING! Risk to life from dangerous gas concen-
trations
An alarm always indicates danger.
●Immediately take all necessary measures for your own
safety and the safety of others.
The concrete measures depend on the situation.
●In the event of a pre-alarm AL1 itmaybesu󰀩cientto
ventilate thoroughly.
●In the event of a main alarm AL2 it may be necessary
to leave the danger zone immediately.
Acknowledgement
Under certain conditions, the audible signal can be muted during
alarms. In some measurement situations, the visual signal and
symbol can also be deactivated. The process is referred to as
acknowledgement.
2Signals when device inspections are due are issued only if the guided
device inspection has been activated using the GasCom software.
