There are 3 main versions of the Polytron 5xx0 family:
– Polytron 5100 EC is intended for electrochemical sensors
(EC sensors).
– Polytron 5200 CAT / Polytron 5310 IR is intended for
catalytic Ex sensors (CatEx sensors) and infrared Ex
sensors (IREx sensors).
– Polytron 57x0 IR is intended for PIR 7x00 sensors.
Gas concentrations, status messages, and menu choices are
displayed on a backlit graphic LC-display and 3 colored LEDs.
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.
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.
The instrument can be operated as current source or sink.
Polytron 5100 EC-specific:
Polytron 5100 EC can be operated in a 2-wire and 3-wire
configuration.
This function changes the operation mode disabling options
which are too power consuming (e. g. current source
operation).
3.3
Configuration possibilities
3.3.1 Interfaces
● 4 to 20 mA analog (per NAMUR recommendation NE43)
● Relay board
3.3.2 Explosion protection
The Polytron 5xx0 instruments are available in 2 explosion
protection types.
● Explosion proof instrument (Ex d)
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.
● Instrument for enhanced safety (Ex e)
The instrument is extended by an increased safety
terminal box (docking station) that 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.
3.4
Intended use
The instruments of the Polytron 5xx0 family can be connected
through a sealed conduit or approved cable gland to a Dräger
monitoring system or a Programmable Logic Controller (PLC).
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.
Instructions for use

Dräger Polytron 5000 Series
Explosion proof (Ex d) installation - without Docking Station
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.
The instrument is designed to be installed in permanent
locations and is approved for use in hazardous, classified
areas.
Polytron 5100 EC-specific
– The Polytron 5100 EC is an explosion proof instrument for
continuous monitoring of toxic gases or oxygen in the
ambient air.
Polytron 5200 CAT-specific
– The Polytron 5200 CAT with catalytic DrägerSensor DD,
DQ or LC is an explosion proof instrument for the
continuous monitoring of combustible gases and vapors
containing hydrocarbons and non-hydrocarbons (e.g.
hydrogen or ammonia) in ambient air.
Polytron 5310 IR-specific
– The Polytron 5310 IR with infrared DrägerSensor IR is an
explosion proof instrument for the continuous monitoring
of combustible gases and vapors containing hydrocarbons
in ambient air.
Polytron 57x0 IR-specific
– Dräger Polytron 5700 IR with PIR 7000 is an explosion
proof instrument for the continuous monitoring of
combustible gases and vapors containing hydrocarbons.
– Dräger Polytron 5720 IR with PIR 7200 is an explosion
proof instrument for the continuous monitoring of carbon
dioxide.
3.5
Approvals
3.5.1 ATEX, IECEx, UL, CSA
See a sample of approval label on the fold-out page. There is
also a printout of the approval label inside the shipping box of
the instrument.
3.5.2 Marking
The marking is reproduced on a separate piece of paper
shipped with the instrument.
Serial Number key: The third letter of the serial number
specifies the manufacturing year: A = 2009, B = 2010, C =
2011, D = 2012, E = 2013, F = 2014, H = 2015, J = 2016, K =
2017, etc.
Example: Serial Number ARJB-0001: the third letter is J,
which means that the unit was manufactured in 2016.
