Description
2.2 Intended use
The Dräger Polytron 5000 is an explosion-proof instrument for
the continuous monitoring of combustible gases and vapors
containing hydrocarbons. The instrument is housed in a rug-
ged, stainless steel or aluminum enclosure for indoor and out-
door 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 oper-
ated as a stand-alone instrument. The instrument is designed
to be installed in permanent locations and is approved for use
in hazardous, classified areas, see Section 8.1 on Page 24.
Caution: Not tested in oxygen enriched atmospheres (>21%

). High off-scale readings may indicate an explosive con-
centration.

2.3 Intended operating area and operating
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&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. Gas concentra-
tions, status messages, and menu choices are displayed on a
4 digit LCD display and 3 colored LEDs. The measured gas
concentration is converted to a 4 to 20 mA analog output
signal. The instrument detects whether it is operating in current
source versus sink mode when power is applied.
Navigation through the menu is done by tapping a magnetic
wand on the glass at the Up and Down arrows or OK .
The instrument can be configured, calibrated and maintained
non-intrusively without declassifying the area.
WARNING
Explosive. Not to be used in oxygen enriched atmo-
spheres. None of the Polytron 5000 instruments are
certified and approved to be operated in oxygen
enriched atmospheres.
