1 Safety Regulations
1.1 Correct Use
The PrimaX Gas Transmitters are fixed gas transmitters for measuring toxic or
combustible gases or oxygen. They are suitable for outdoor and indoor applications
without limitations, e.g. offshore industry, chemical and petrochemical industry, wa-
ter and sewage industry. The signal of the transmitter can be used in combination
with MSA control units for further actions in safety or non safety applications, e. g.
MSA SUPREMA, Gasgard XL, 9010/9020.
The two versions of the gas transmitter are delivered either in a flameproof or in a
intrinsically safe enclosure. The electrical parts and interfaces have the same basic
functionality.
It is imperative that this operating manual be read and observed when using the
product. In particular, the safety instructions, as well as the information for the use
and operation of the product, 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-compli-
ance. This also applies especially to unauthorised alterations to the product 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 respon-
sibility 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, mainte-
nance or servicing may affect the function of the device and thereby se-
riously 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 compe-
tent servicing/maintenance has not been made, genuine MSA spare
parts have not been used.

1.3 Safety and Precautionary Measures to be Adopted
- The device described in this manual must be installed, operated and maintained
in strict accordance with their labels, cautions, instructions, and within the limi-
tations stated.
- The device is designed to detect gases or vapours in air.
- Protect the device from extreme vibration. Do not mount the sensing head in di-
rect sunlight as this may cause overheating of the sensor.
- The device must be installed with the sensor inlet pointing downwards to avoid
clogging of the gas inlet by particles or liquids.
- Electrochemical sensors are sealed units which contain a corrosive electrolyte.
Should a sensor develop leakage, it must be immediately removed from service
and disposed of properly. Caution must be exercised so that the electrolyte
does not contact skin, clothing or circuitry otherwise personal injury [burns] and/
or equipment damage may result.
- The only absolute method to ensure proper overall operation of the device 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 inspec-
tion of the system.
- As with all devices of these types, high levels of, or long exposure to, certain
compounds in the tested atmosphere could contaminate the sensor. In atmos-
pheres where the device may be exposed to such materials, calibration must be
performed frequently to ensure that the operation is dependable and display in-
dications are accurate.
- The device must not be painted. If painting is done in an area where a device is
located, care must be exercised to ensure that paint is not deposited on the sin-
tered metal flashback arrestor in the gas sensor inlet, if so equipped. Such paint
deposits would interfere with the gas diffusion process.
- Use only genuine MSA replacement parts when performing any maintenance
procedures provided in this manual. Failure to do so may seriously impair instru-
ment performance. Repair or alteration of the device, beyond the scope of these
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.

MSASafety Regulations
PrimaX
8GB
maintenance instructions or by anyone other than an authorised MSA service
personnel, could cause the product to fail to perform as designed.
- The device is designed for applications in hazardous areas under atmospheric
conditions.
- For correct measurements, the combustible gas sensors require an oxygen
concentration greater than 10 Vol%. Oxygen enriched atmospheres, greater
then 21 Vol%, can affect the measurement and the electrical safety of the de-
vice.
- The response time of the device will be increased by significant dust deposits
on the Sensor. Checks for dust deposits must be done at regular intervals.
- Catalytic combustible gas sensors may produce low or zero response to com-
bustible gas after exposure to substances as Silicon, Silane, Silicate, Halide
and compounds containing Fluorine, Chlorine, Iodine or Bromine.
1.4 MSA Permanent Instrument Warranty
Warranty
Seller warrants that this product will be free from mechanical defect or faulty work-
manship for
- Gas Transmitter: eighteen [18] months from date of shipment or one [1] year
from installation, whichever occurs first;
- Oxygen, Toxic or Catalytic Combustible Sensor: eighteen [18] months from date

This warranty is applicable provided the product is maintained and used in accord-
ance with Seller's instructions and/or recommendations. This warranty does not ap-
ply to expendable or consumable parts, whose normal life expectancy is less than
one [1] year.
The Seller shall be released from all obligations under this warranty in the event re-
pairs or modifications are made by persons other than its own or authorized service
personnel or if the warranty claim results from physical abuse or misuse of the prod-
uct. No agent, employee or representative of the Seller has any authority to bind the
Seller to any affirmation, representation or warranty concerning the goods sold un-
der this contract. Seller makes no warranty concerning components or accessories
not manufactured by the Seller, but will pass onto the Purchaser all warranties of
manufacturers of such components.

purpose version [not intended for hazardous area] or intrinsically safe version. Both
versions are designed for a detection of toxic gases or oxygen.
2.2 Overview
The device is factory-calibrated and delivered ready for installation. Each device is
configured and calibrated for only one specific gas or vapour.

As an optional feature additional modules are available for these configurations of
PrimaX transmitter:
For more information on the HART module →chapter 4.7.
3 Installation
The device should be installed where gas leaks are expected. The installation po-
sition depends on the gas density, either in the upper area of the room under the
ceiling for gases lighter than air or close to the ground for gases heavier than air.
Also consider how air movement may affect the abilty of the device to detect gas.
The display on the front of the instrument must always be clearly visible, the view
must not be obstructed.

Instructions for Electrical Connection
- Shielded cable for measuring devices is recommended.
- Always observe maximum cable lengths and cross-sections [→chapter 6.2].
- Water or impurities can penetrate the instrument through the cable. In hazar-
dous areas, it is recommended to install the cable in a loop just before entry into
the instrument or to slightly bend it to prevent water from entering.

4.3 Calibrations
General
The calibration must be done at regular intervals in accordance with applicable na-
tional and regional regulations.
The device is calibrated at the factory. Nevertheless, it is recommended to re-
calibrate the device after installation. The frequency of calibration depends on the
duration of use and the chemical exposure of the sensor. New sensors must be
calibrated frequently until it is clear from the calibration data that they have stabi-
lised.

Connect power to the device at least one hour before attempting a cal-
ibration.
Carry out the calibration during commissioning as well as at regular in-
tervals. This ensures optimum operation of the sensor.
It is recommended that all calibration components are connected before
starting a calibration as it is necessary to apply test gas to the device
during a countdown.
The calibration can be performed as a manual or an automatic calibra-
tion [→M-04].
