1.1 Correct use
The PrimaX Gas Transmitters are fixed gas transmitters for measuring toxic or combustible gases and
for monitoring oxygen deficiency, excess or inerting. They are suitable for outdoor and indoor applica-
tions without limitations, e.g. offshore industry, chemical and petrochemical industry, water 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 device. In particular,
the safety instructions, as well as the information for the use and operation of the device, must be care-
fully read and observed. Furthermore, the national regulations applicable in the user's country must be
taken into account for a safe use.
WARNING!
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.
Alternative use, or use outside this specification will be considered as non-compliance. 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.

1.3 Safety and Precautionary Measures to be Adopted
WARNING!
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 device, be guaranteed.
• The device described in this manual must be installed, operated and maintained in strict accor-
dance with their labels, cautions, instructions, and within the limitations stated.
• The device is designed to detect gases or vapours in air.
• If a device with a combustible sensor is exposed to vibrations, calibration shall be done in sufficient
short intervals until it is verified that the device is not affected by the vibration stress.
• Do not mount the sensing head in direct sunlight as this could 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
