2.2 Intended use
The Dräger Polytron 8100 is an explosion proof instrument for
continuous monitoring of toxic gases or oxygen in the ambient
air. The instrument is housed in a rugged stainless steel or
aluminum enclosure for indoor and outdoor applications. The
instrument can be connected through a sealed conduit or
approved cable gland to a Dräger monitoring system or a
Programmable Logic Controller (PLC). With the optional alarm
relay configuration, the instrument can be operated as a stand-
alone unit. The instrument is designed to be installed in
permanent locations and is approved for use in hazardous,
classified areas, see Section 10.1 on Page 38. With the
optionally integrated relay module, the instrument can be
operated without a central controller (with additional local
alarm signaling).
For a safe operation in accordance with BVS 13 ATEX G001 X,
the connection to a central controller is necessary. This also
applies if all relays are connected because the fault relay is not
activated during maintenance. In any case, the analog output
must be monitored because it might indicate a special status
by a current between 0 and 3.5 mA. Additionally Dräger
Polytron 8100 is available with fieldbus interfaces. Using the
fieldbus interface no relays are available. The fieldbus
interface is not in accordance with the BVS 13 ATEX G 001 X.
2.3 Intended operating area and conditions
Hazardous areas classified by zones:
The device is intended to be used only in hazardous areas
classified Zone 1 or Zone 2, within a temperature range as
marked on the device, where gases of explosion Groups IIA,
IIB or IIC and temperature class T4 or T6 (depending on the
maximum ambient temperature) or dusts of Groups IIIA, IIIB or
IIIC may be present.
Hazardous areas classified by divisions:
The device is intended to be used only in hazardous areas
Class I or II, Div. 1 or Div. 2, within a temperature range as
marked on the device, where gases or dusts of Groups A, B,
C, D or E, F, G and temperature class T4 or T6 (depending on
the maximum ambient temperature) may be present.
2.4 Design
The instrument is powered by 10 to 30 VDC (see Section 10.4
on Page 43). Gas concentrations, status messages, and menu
choices are displayed on a backlit graphic LC-display and 3
colored LEDs. The measured gas concentration is converted
to a 4 to 20 mA analog (per NAMUR recommendation NE43)
or a digital HART output signal. The instrument can be
operated as current source or sink. Optionally the instrument
can be equipped with a fieldbus interface allowing the
integration in an asset management system. Using the
fieldbus interface no relays are available. The fieldbus
interface is not in accordance with the BVS 13 ATEX G 001 X
Navigation through the menu is done by taping a magnetic
wand on the glass at the appropriate indicator.
The instrument can be configured, calibrated and maintained
non-intrusively without declassifying the area.
NOTICE

Installation
Dräger Polytron 8100 9
3 Installation
3.1 General information for installation
To ensure overall system performance and effectiveness, the
selection of an installation site for the instrument is one of the
most important factors. Strict compliance where possible and
considerable thought must be given to every detail of
installation, particularly:
the local, state, national codes and regulations that govern
the installation of gas monitoring equipment.
the electrical codes that govern the routing and connection
of electrical power and signal cables to gas monitoring
equipment.
for non-conduit installations, an approved cable gland must
be used, see Section 10.1 on Page 38 (e.g. Hawke A501/
421/A/¾” NPT or equivalent). It might be necessary to
connect the shield of the cable to the cable gland and to the
controller in order to improve RFI immunity.
the full range of environmental conditions to which the
instruments will be exposed to.
the physical data of the gas or vapor to be detected.
the specifics of the application, (e.g. possible leaks, air
movement/draft, etc.).
the degree of accessibility required for maintenance
purposes.
the types of optional and accessory equipment that will be
used with the system.
any other limiting factors or regulations that would affect
system performance or installations.
the flameproof / explosion proof enclosure provides three
¾" NPT openings, which can be used for field wiring, direct
attachment of a sensor or wiring of a remote sensor.
unused openings must be closed with a plug. For correct
tightening torques of conduit hubs, cable glands, plugs and
sensor see Section 10.9 on Page 44.
secondary circuit intended to be supplied from an isolating
source (N/A for relay circuits).
the optional increased safety terminal box provides up to
four 20 mm openings, which can be used for field wiring or
wiring of a remote sensor. The permissible cable diameter
range is 7 to 12 mm.
In case of optional increased safety terminal box, securely
screw the transmitter onto the docking station using 4
screws with a tightening torque of 8Nm.
when installed at locations exceeding ambient
temperatures of 55 °C, use only appropriate wiring,
specified for at least 25 °C above the maximum ambient
temperature.
strip wire insulation by 5 to 7 mm.
connect the wires as indicated in wiring figure Section 3 on
Page 9 (also showing grounding conductor terminal).
the wiring for the optional relay module must be selected
and fused according to the rated voltages, currents and
environmental conditions.
if stranded conductors are used, a ferrule must be used.
For further information regarding the fieldbus interface
installation consult the corresponding Technical Handbook.
3.2 Installation restrictions
The instrument must have between 10 to 30 VDC at the
instrument. This ultimately determines the distance the
instrument can be mounted from the controller or power
supply. The instrument accepts wire sizes of 12 to 24 AWG
(0.2 to 2.5 mm²). Use at least a three-conductor, shielded
cable.
The instrument must not be exposed to radiant heat that
will cause the temperature to rise beyond the limits stated
in see Section 10.7 on Page 44. The use of a reflecting
shield is recommended.
The enclosure is weatherproof within environmental
parameters and suitable for outdoor installation. The use of
the optional splash guard (6812510) is recommended to
protect the sensor from water and dust.
Each instrument must be installed and operated in an
environment that conforms to the specifications, see
Section 10 on Page 38.
To ensure proper operation of the instrument, 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 observed (see Section 3.3
on Page 10). The conductors for the power supply must
have an adequately low resistance to ensure the correct
supply voltage at the instrument.
Recommended orientation: Sensor orientation downwards
as shown in Section 3.7 on Page 12.
NOTICE
The instrument may be equipped with a dust plug at
the conduit entry. This plug is not explosion proof nor
meant to be watertight, and must be removed before
connecting the instrument to a sealed conduit or
installation of a flameproof cable gland.
CAUTION
Not tested in oxygen enriched atmospheres
(>21% O2). High off-scale readings may indicate an
explosive concentration.
WARNING
Danger of explosions. Not to be used in oxygen
enriched atmospheres. None of the Polytron 8100
instruments are certified and approved to be operated
in oxygen enriched atmospheres.

3.6 Electrical installation with Docking
Station
Installing this configuration is a two-step process.
First, the Docking Station is mounted and connected to the
field wires. Second, the main instrument enclosure with the
electronics and sensor is attached to the Docking Station.
The Docking Station can be pre-mounted, wired and sealed
with the supplied cover. Once the site is ready for
commissioning, the instrument is then hooked up to the
Docking Station and taken into operation; avoiding that the
instrument is damaged during the construction phase.
The connection between the Docking Station and the main
instrument is realized via a ‘feedthrough’. Depending on the
instrument selected, there are 2 types of feed-through.
feedthrough 3 wires for power (part number 4544182)
feedthrough 9 wire for power and relay (part number

4 Operation
4.1 Normal operation
1. Switch power supply on.
The instrument will go through a start-up sequence (LCD / LED
test, software version, and initialization) and start the warm-up
period. The display shows that the sensor will be ready for
measurement in hh:mm:ss (countdown) and the instrument
transmits the maintenance signal, see Section 10.3 on
Page 43. The fault relay is activated.
After the warm-up period, the instrument goes into normal
operation. The display shows the current gas concentration,
the selected gas and the units of measurement. The green
LED is lit.
4.1.1 Analog signals
The current output of the instrument during normal operation is
between 4 and 20 mA and is proportional to the detected gas
concentration.
Polytron 8xx0 uses different current values to indicate various
modes of operation. The factory default settings are user
adjustable for application specific requirements, see Section 7
on Page 36. This follows the NAMUR recommendation NE43.

5.7 Combinations of acknowledgments,
latching and the corresponding relay/
LED status
This section gives explanation of combining latching,
acknowledgment and pre-acknowledgment of alarms and the
corresponding LED status.
5.7.1 Acknowledgments and latching
Latching means that once the alarm level is reached, the
instrument will trigger the alarm. It will remain in alarm status
even if the gas concentration subsequently does not meet the
alarm condition any more. To clear a latching alarm it has to be
acknowledged with [OK].
In non-latching mode, the alarm status clears if the gas
concentration does not meet the alarm condition anymore.
Acknowledgeable means that alarm relay and LED can be
reset before alarm condition clears.
Pre-acknowledgeable means that the alarm status is
acknowledgeable before the alarm condition clears.
However, the alarm relay and LED stay active until the
alarm condition clears.
Non-acknowledgeable means that alarm relay and LED
can not be reset until the alarm condition clears.
5.7.2 LED status:
When the first alarm (pre alarm) has been triggered the red
LED flashes in single mode.
When the second alarm (main alarm) has been triggered
the red LED flashes in double mode.
With the non-relay version the red LED flashes to inform
visually and no relay is energized. To energize the A1 or A2
relay the optional relay board must be installed.
For LED flashing patterns depending on combinations of
acknowledgements and latching, see 5.7.3 on Page 20.
NOTICE
SIL lock is only available for certain sensors (refer to
the Polytron 8xx0 Safety Manual part number
9033307).
SIL lock can only be activated if the sensor test is
activated see Section 5.10.9 on Page 28.
NOTICE
When SIL is activated, the instrument displays all
safety-relevant parameters and settings before
returning to normal operation. Carefully review all
parameters and settings and confirm.
