and then removing it. Referred to as tap. Since the magnetic field penetrates the window, the enclosure cover is not
removed in order to perform calibration.
Three alarm points are preprogrammed into the EX-5130-IS sensor/transmitters. At each alarm point, an LED on the
front panel is activated. These internal alarm settings are independent of the 4-20mA output alarm values that can be
set at a controller.

:
Area must be declassified during installation.
The ENMET EX-5130-IS gas sensor/transmitter (S/T) is a 3-wire, 24 VDC, 4-20 mA S/T for the detection of toxic
gas. The S/T is meant to be used in conjunction with an appropriate power supply and controller. The ENMET EX-
5130-IS sensor/transmitter has been designed to be used in a Class I, Div. 1, Groups B, C, D, classified areas.
Appropriate wiring, conduit and fittings are required for proper installation in a explosion proof rated environment.
: 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.
Also, 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 know hazards. Also, take precautions to
insure condensation inside of the conduit does not enter the S/T.
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.
: Before connecting S/T to controller remove the power source to controller. Failure to do so may cause
damage to sensitive components.
