General Warnings and Cautions
1. The Ultima XI Infrared Gas Monitors described in this manual
must be installed, operated and maintained in strict accordance
with their labels, cautions, warnings,instructions, and within the
limitations stated. Verify that the class, group, and temperature
ratings of the equipment agree with the actual classification of
the location.
2. The Ultima XI Infrared Gas Monitor is designed to detect gases
or vapors in air. It can also measure the concentration of gases or
vapors in steam or inert or oxygen-deficient atmospheres. .
3. 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 XI Infrared Gas Monitor, beyond the scope of these
maintenance instructions or by anyone other than authorized MSA
service personnel, could cause the product to fail to perform as
designed.
4. The Ultima XI Infrared 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.
5. The standard Ultima XI Infrared Gas Monitor does not detect the
presence of acetylene gas. The presence of acetylene gas will
desensitize sensor performance. Custom-built acetylene sensors
are available through your MSA representative.
6. CSA performance Certification to standard C22.2 No. 152 is valid
only when the instrument is calibrated on methane per the
instruction manual.
"WARNING
ii
1. As with all gas monitors of this type, high levels of, or long
exposure to, certain compounds in the tested atmosphere could
contaminate the sensors. In atmospheres where an Ultima XI
Infrared Gas Monitor may be exposed to such materials, calibration
must be performed frequently to ensure that operation is
dependable and display indications are accurate.
2. The Ultima XI Infrared 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
environmental shield of the Ultima XI Infrared 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.
3. The only absolute method to ensure proper operation of an Ultima
XI Infrared 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.
4. Protect the Ultima XI Infrared Gas Monitor from extreme vibration.
FAILURE TO FOLLOW THE ABOVE CAN RESULT IN PRODUCT
DAMAGE AND/OR AN UNSAFE CONDITION.

Installation
General Description
The Ultima XI Infrared Gas Monitor is designed to sample the
environment where mounted and alert you to potentially dangerous
levels of combustible gas. The Ultima XI Infrared Gas Monitor is
shipped factory-calibrated and is labeled with target gas, calibration gas
and span setting information. The target gas is not field-configurable
and cannot be changed. The Ultima XI Gas Monitor is a stand-alone
unit with a 4 to 20 mA output.
Identifying Your Unit
• The Ultima XI Infrared Gas Monitor is housed in a 316 stainless
steel explosion-proof enclosure (FIGURE 1-1).
Do not mix units with different area classifications. All units
Figure 1-1. Explosion-Proof Ultima XI Infrared Gas Monitor
• The Ultima XI Infrared Gas Monitor is also available with an
optional junction box equipped with a terminal strip for easy wiring
(FIGURE 1-2).
Do not mix units with different area classifications. All units
Installing Your Gas Monitor
Generally, the Ultima XI Gas Monitor should be mounted close to the
area where a leak is likely to occur or where the gas is expected.
Testing for ventilation patterns may be helpful in establishing locations
for the Ultima XI Gas Monitor in enclosed areas. Smoke tubes
(P/N 458481) are useful in measuring these patterns to help determine
where gases may flow or accumulate.
Mount the Ultima XI Gas Monitor on a support by using suitable
hardware (not supplied), and attach rigid conduit and a conduit seal
fitting (for XP installations). The optional condulet assembly can also be
used for wiring power and signal.
NOTE: The XI Gas sensor must be mounted with the sensor
extended horizontally as shown in FIGURE 1-2.
The Ultima XI Infrared Gas Monitor contains no user- or field-
serviceable parts and must be returned to the factory for
repair. Any attempt to open the monitor will damage the unit
and void the warranty.
Mount the Ultima XI Infrared Gas Monitor with the sensor
inlet fitting extended horizontally from the main enclosure
(FIGURES 1-1 and 1-2). Horizontal mounting will help pre-
vent the build-up of particulate or liquid matter on the moni-
tor's optical surfaces.
"CAUTION
"WARNING
Figure 1-2. Explosion-Proof Ultima XI Infrared Gas Monitor
with Junction Box
1-2
Do not paint the Ultima XI Infrared Gas Monitor. If painting is
done in an area where a sensor is located, exercise caution
to ensure paint is not deposited on the sensor inlet fitting.
Such paint deposits would interfere with the diffusion
process, whereby a sample of the monitored atmosphere
diffuses into the sensor. In addition, solvents in the paint
may cause an alarm condition to occur.
Protect the Ultima XI Infrared Gas Monitor from extreme
vibration. Do not mount sensing head in direct sunlight as
this may cause the sensor to overheat.
During sensor installation or removal, do not use any tools
or apply excessive force to the two legs that support the
unit's reflectors (FIGURE 1-3). Applying force to the legs can
permanently damage the monitor.
The monitor's environmental guard should be installed on
the unit at all times. If the monitor is to be operated without
the guard, frequent checks should be made to ensure par-
ticulate or liquid matter has not collected on the windows.
Use a wrench on the hex nut in the sensor neck to install or
remove the sensor.
Do not mix units with different area classifications. All units
