!
2.2 Intended use
The Dräger Polytron 8000 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 standalone 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 37. With the
optionally integrated relay module, the instrument can be
operated without a central controller (with additional local
alarm signaling).
For safe operation, 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.
CAUTION
Not tested in oxygen enriched atmospheres
(>21% O2). High off-scale readings may indicate an
explosive concentration.
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 41). 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.
Navigation through the menu is done by taping a magnetic
wand on the glass at the appropriate indicator.
WARNING
Danger of explosions. Not to be used in oxygen
enriched atmospheres. None of the Polytron 8000
instruments are certified and approved to be operated
in oxygen enriched atmospheres.
The instrument can be configured, calibrated and maintained
non-intrusively without declassifying the area.

Installation
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 37 (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 10.8 on Page 42.
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.
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 8 (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.
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 10.6 on Page 41. 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 37.
To insure 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 8). The conductors for the power supply must
have an adequately low resistance to insure the correct
supply voltage at the instrument.
NOTICE
i
i
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.

adjustable for application specific requirements, see Section 7
on Page 34. This follows the NAMUR recommendation NE43.
4.1.2 The display and LEDs
In normal operation, the display shows the measured gas
concentration, the selected gas and the unit of measurement.
The green LED is lit.
The following symbols may also be displayed:
" ", when the measuring range is exceeded
" - - - - " and " X " when a fault has been detected. The
yellow LED is lit, see Section 6.3 on Page 31.
"SIL", when SIL status is activated.
If the optional relay board is installed:
When the first alarm (pre alarm) has been triggered the red
LED blinks in single mode. The A1 relay is asserted.
When the second alarm (main alarm) has been triggered
the red LED blinks in double mode. The A2 relay is
asserted.
If the A2 is configured as acknowledgeable, and the A1 is
configured as non-acknowledgeable, then, when an A2
alarm occurs, the red LED will blink in double blink A2
mode. After the alarm is acknowledged, the red LED will
blink in single blink mode to indicate A1 is still active.
