Feature description
®
Polytron
8xx0 instruments are housed in a rugged stainless
steel or aluminum enclosure for indoor and outdoor
applications.
There are 3 main versions of the Polytron
®
– Polytron
8100 EC is intended for electrochemical
sensors (EC sensors).
®
– Polytron
8200 CAT / Polytron
catalytic Ex sensors (CatEx sensors) and infrared Ex
sensors (IREx sensors).
®
– Polytron
87x0 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.
The instrument come with a data logger. For information on
how to handle the data logger, see the technical manual.
The data logger can store up to 35000 values. At a sampling
interval of 1 measurement per minute the data logger stores
the measurement history of approximately 24 days. This time
can be significantly increased if the trigger function is enabled.

3.3.3 Explosion protection
®
The Polytron
8xx0 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 increased 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
continuous monitoring of the ambient air.
With the optionally integrated relay module, the instrument
can be operated without a control unit (with additional local
alarm signaling).
With a sealed conduit or approved cable gland, the instrument
can be connected to a Dräger control unit or a Programmable
Logic Controller (PLC).
If the 4 - 20 mA interface is used, the current between 0 and
3.5 mA must be monitored. Currents between 0 and 3.5 mA
can indicate a special state.
1) Using the fieldbus interface no relays are available. The fieldbus inter-
face is not in accordance with the BVS 13 ATEX G 001 X.
