1 Safety Regulations
1.1 Correct Use
The ULTIMA XL/ULTIMA XT Series are fixed gas monitors for measuring toxic and
combustible gases as well as oxygen. They are suitable for outdoor and indoor applications without limitations, e.g. offshore industry, chemical and petrochemical industry, water and sewage industry. Using sensors, the instruments test the ambient
air and trigger the alarm as soon as the gas exceeds a specific concentration level.
It is imperative that this operating manual be read and observed when using the
ULTIMA XL/ULTIMA XT Series of gas monitors. In particular, the safety instructions, as well as the information for the use and operation of the apparatus, must be
carefully read and observed. Furthermore, the national regulations applicable in the
user's country must be taken into account for a safe use.
Alternative use, or use outside this specification will be considered as non-compliance. This also applies especially to unauthorised alterations to the apparatus and
to commissioning work that has not been carried out by MSA or authorised persons.
1.2 Liability Information
MSA accepts no liability in cases where the product has been used inappropriately
or not as intended. The selection and use of the product are the exclusive responsibility of the individual operator.
Product liability claims, warranties also as guarantees made by MSA with respect
to the product are voided, if it is not used, serviced or maintained in accordance with
the instructions in this manual.
Danger!
This product is supporting life and health. Inappropriate use, maintenance or servicing may affect the function of the device and thereby seriously compromise the user’s life.
Before use the product operability must be verified. The product must
not be used if the function test is unsuccessful, it is damaged, a competent servicing/maintenance has not been made, genuine MSA spare
parts have not been used.
MSASafety Regulations
ULTIMA XL/ULTIMA XT

GB
1.3 Safety and Precautionary Measures to be Adopted
(1) The ULTIMA X Series Gas Monitors described in this manual must be in-
stalled, operated and maintained in strict accordance with their labels, cautions, warnings, instructions, and within the limitations stated.
(2) The ULTIMA X Series Gas Monitor is designed to detect gases or vapors in
air. It cannot measure the concentration of gases or vapors in steam or inert
or oxygen-deficient atmospheres. The oxygen sensor can measure oxygendeficient atmospheres.
(3) Electrochemical sensors are sealed units which contain a corrosive electro-
lyte. Should a sensor develop leakage, it must be immediately removed from
service; then, remove it from the sensing head and discard it properly. Caution
must be exercised so that the electrolyte does not contact skin, eyes, clothing
or circuitry; otherwise, serious personal injury [burns] and/or equipment damage may result.
(4) Use only genuine MSA replacement parts when performing any maintenance
procedures provided in this manual. Failure to do so may seriously impair instrument performance. Repair or alteration of the ULTIMA X Series Gas Monitor, beyond the scope of these maintenance instructions or by anyone other
than an authorized MSA service personnel, could cause the product to fail to
perform as designed and persons who rely on this product for their safety
could sustain serious personal injury or loss of life.
(5) General-purpose [GP] ULTIMA X Series Gas Monitors can be a source of ig-
nition. Install, locate, and operate GP models in a non-hazardous area and in
accordance with all applicable codes. If a hazardous area must be monitored,
use only an explosion-proof/ flameproof ULTIMA X Series Gas Monitor model.
(6) The ULTIMA XIR Infrared combustible gas monitor detects the presence of
most combustible gases by identifying the difference in the amount of infrared
light energy absorbed during the presence of these gases. This monitor, however, does NOT detect the presence of hydrogen gas and must never be used
to monitor for hydrogen gas.
(7) The standard ULTIMA XIR Infrared Combustible Gas Monitor does not detect
the presence of acetylene gas and the presence of acetylene gas will degrade
sensor performance. Custom-built acetylene sensors are available through
your MSA representative.
Attention!
The following safety instructions must be observed implicitly. Only in this
way can the safety and health of the individual operators, and the correct
functioning of the instrument, be guaranteed.
Safety RegulationsMSA
ULTIMA XL/ULTIMA XT
GB
11
(8) As with all gas monitors of these types, high levels of, or long exposure to, cer-
tain compounds in the tested atmosphere could contaminate the sensors. In
atmospheres where an ULTIMA X Series Gas Monitor may be exposed to
such materials, calibration must be performed frequently to ensure that operation is dependable and display indications are accurate.
(9) The ULTIMA X Series Gas Monitor must not be painted. If painting is done in
an area where a Monitor is located, care must be exercised to ensure that
paint is not deposited on the sintered, metal flashback arrestor in the inlet fitting of the ULTIMA X Series Gas Monitor, if so equipped. Such paint deposits
would interfere with the diffusion process, whereby a sample of the atmosphere being monitored diffuses into the Monitor.
(10) The only absolute method to ensure proper overall operation of an ULTIMA X
Series Monitor is to check it with a known concentration of the gas for which it
has been calibrated. Consequently, calibration checks must be included as
part of the routine inspection of the system.
(11) Protect the ULTIMA X Series Gas Monitor from extreme vibration. Do not
mount the sensing head in direct sunlight as this may cause overheating of the
sensor.

Five conductors are required for the ULTIMA XL and ULTIMA XT Remote Sensor
Modules to operate catalytic or electrochemical sensor modules of the ULTIMA XE
type. Four conductors are required for the ULTIMA XIR Remote Sensor Module.
The ULTIMA X Series Monitor has a five-wire terminal to accommodate up to
1.50 mm
2
[16 AWG] conductors.
For open wiring, shielded wire or cable should be used to minimize the possibility
of noise interference and contact with other voltages. Selection of this shielded cable must comply with local requirements.
Warning!
Before wiring the ULTIMA X Series Remote Sensor Module, disconnect
the power source feeding the Remote Sensor Module and the ULTIMA X
Series Gas Monitor/Less Sensor; otherwise, electrical shock could occur.
Attention!
When installing an ULTIMA X Series Remote Sensor Module with its
mating ULTIMA X Series Gas Monitor/Less Sensor, follow National
Electrical and local procedural Codes for US, or relevant codes for country of installation; failure to do so can result in an unsafe condition.

Remote Module Wiring and Placement
At the ULTIMA X Series Remote Sensor Location:
(1) Open the ULTIMA X Series Remote Sensor cover by removing lid.
For the ULTIMA XT Gas Monitor, route the cable from the Gas Monitor
through a customer-supplied opening in the enclosure and wire it to the terminal block [Æ Fig. 4].
For the ULTIMA XL or XLIR Gas Monitor, route the cable from the Gas Mon-
itor through a wire entry hole in the enclosure and wire it to the terminal block
[Æ Fig. 5 or Æ Fig. 6].
(2) Verify the identity of each conductor of the cable and connect the wire to the
terminal block.
(3) Re-install the cover of the ULTIMA X Series Remote Sensor.
