The
EX-6120, 6165 S
ERIES
IR
gas sensor/transmitter (S/T) is a 3-wire, 24
V
DC
4-20 mA S/T for the detection of
combustible gas. The S/T is meant to be used in conjunction with an appropriate power supply and controller. The
EX-
6120, 6165 S
ERIES
IR
sensor/transmitter is in an enclosure rated for use in area listed below:

Appropriate wiring, conduit and fittings are required for proper installation in an explosion proof rated environment.
C
AUTION
:
Since the sensor/transmitter detects gas only at the sensor location, pay attention to the possible sources of gas,
the density of the gas, locations where the gas may be confined and locations where the gas may damage or
injure property or personnel, when choosing locations of sensor/transmitters.
Take into consideration environmental factors when deciding on S/T location. Avoid locations where the S/T may be
damaged by liquid immersion, excessive heat or other known hazards. Also, take precautions to insure condensation
inside of the conduit does not enter the S/T.
3.1 Mounting the EX-6120, 6165 S
ERIES
IR Enclosure
Mount the enclosure, using the two mounting holes provided see Figure 2. Pay particular attention to the source and
density of the gas being detected when choosing the location. Mount the S/T near the ceiling for lighter than air gases
/vapors and near the floor for heavier then air gas/vapors. Contact
ENMET
if you have questions regarding your
application.
C
AUTION
:
Before connecting S/T to controller remove the power source to controller. Failure to do so may cause damage
to sensitive components.
