1.0 Introduction
The ENMET EX-5120 infrared sensor/transmitter (S/T) is a 3-wire, 24Vdc, 4-20mA S/T for the detection of combustible gas.
The EX-5120 is meant to be used in conjunction with an appropriate power supply and controller.
The ENMET EX-5120 sensor/transmitter has been designed for use in a Class I, Div. 1, Groups B, C, D, classified areas.

OTE
: All specifications stated in this manual may change without notice.
1.1 Unpack
Unpack the EX-5120 and examine it for shipping damage. If such damage is observed, notify both ENMET customer service
personnel and the commercial carrier involved immediately.
Regarding Damaged Shipments
N
OTE
: It is your responsibility to follow these instructions. If they are not followed, the carrier will not honor
any claims for damage.
This shipment was carefully inspected, verified and properly packaged at our company and delivered to the carrier in
good condition.
When it was picked up by the carrier at ENMET, it legally became your company’s property.
If your shipment arrives damaged:
• Keep the items, packing material, and carton “As Is.” Within 5 days of receipt, notify the carrier’s local office and
request immediate inspection of the carton and the contents.
• After the inspection and after you have received written acknowledgment of the damage from the carrier, contact
ENMET Customer Service for return authorization and further instructions. Have your Purchase Order and Sales
Order numbers available.
ENMET either repairs or replaces damaged equipment and invoices the carrier to the extent of the liability coverage,
usually $100.00. Repair or replacement charges above that value are your company’s responsibility.
The shipping company may offer optional insurance coverage. ENMET only insures shipments with the shipping
company when asked to do so in writing by our customer. If you need your shipments insured, please forward a written
request to ENMET Customer Service.
Regarding Shortages

:
Area must be declassified during installation.
The ENMET EX-5120 gas sensor/transmitter (S/T) is a 3-wire, 24 Vdc, 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 ENMET EX-5120 sensor/transmitter is in an enclosure rated for use in a Class I, Div. 1, Groups B, C, D, classified area.
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 known 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. 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.

5.2 Calibration of the EX-5120
Calibration is the process of setting the instrument up to read accurately when exposed to a target gas. The Zero function sets
the clean air reference point and the Span function sets the sensitivity of the instrument.
Initial Calibration:
before initial calibration. The S/T has been precalibrated at the factory, and initial field calibration should result in only fine
tuning to circuit, as well as a way to check that installation is successful. It is not necessary to open the enclosure to make
adjustment. The calibration functions are operated with magnets from outside the enclosure through the
switches. Do Not open the S/T unless the area is de-classified.
Calibration Zero and Span functions are two separate procedures. They operate independently of each other. It is
recommended that the Zero procedure be done prior to the Span procedure.

Generally, a cylinder of 20.9% Oxygen is used to provide a fresh air reference or Zero point for the calibration. Another
cylinder is used to provide the Span reference point for calibration. Depending on the instrument calibration, the Span gas may
be the same gas that the instrument is calibrated to display, or it may be another gas, which

To replace a sensor, it is not necessary to open the transmitter housing.
Remove the set screw from sensor housing base.
Unscrew the sensor housing cover and remove Sensor/PC Board Assembly.
Plug in new Sensor/PC Board Assembly.
Reassemble the sensor housing.
After the new sensor has been installed, it is suggested to allow the sensor to stabilize for several minutes.
A Factory calibration must be performed.
After entering the Maintenance menu, advance to the Zero menu. Then while viewing the Zero menu, hold the magnet over the

After 2-4 seconds, an F will appear on the far right hand side of the display. The F indicates that the instrument is in Factory
mode.
Perform the calibration Zero and Span procedures as outlined in Section 5.2. Be sure that the F is present when selecting the
Zero and Span functions.
The Factory calibration sets a calibration window for future standard instrument calibrations.
Only perform a factory calibration when installing a new sensor!!

Returning an Instrument for Repair
ENMET instruments may be returned to the factory or any one of our Field Service Centers for regular repair
service or calibration. The ENMET Repair Department and Field Service Centers also perform warranty
service work.
When returning an instrument to the factory or service center for service, paperwork must be included which
contains the following information:
A purchase order number or reference number.
A contact name with return address, telephone and fax numbers
Specific instructions regarding desired service or description
of the problems being encountered.
Date of original purchase and copy of packing slip or invoice
for warranty consideration.
If a price estimate is required, please note it accordingly and be
sure to include a fax number.
Providing the above information assists in the expedient repair and return of your unit.
Failure to provide this information can result in processing delays.
ENMET charges a one hour minimum billing for all approved repairs with additional time billed to the closest
tenth of an hour. All instruments sent to ENMET are subject to a minimum evaluation fee, even if returned
unrepaired. Unclaimed instruments that ENMET has received without appropriate paperwork or attempts to
advise repair costs that have been unanswered, after a period of 60 days, may be disposed of or returned
unrepaired COD with the evaluation fee.
Service centers may have different rates or terms. Be sure to contact them for this information.
Repaired instruments are returned by UPS/FedEx Ground and are not insured unless otherwise specified. If
expedited shipping methods or insurance is required, it must be stated in your paperwork.
Note: Warranty of customer installed components.
If a component is purchased and installed in the field, and fails within the warranty term, it can be
returned to ENMET and will be replaced, free of charge, per ENMET’s returned goods procedure.
If the entire instrument is returned to ENMET Corporation with the defective item installed, the item will
be replaced at no cost, but the instrument will be subject to labor charges at half of the standard rate.
