Consilium ST350 Quick Installation Manual

QUICK INSTALLATION GUIDE
Consilium ST350/ST450/ST650
NOTE! Read and understand this entire guide before
installing the detector. It contains information that is
essential for your safety and for the correct installation
and operation of the Consilium detector.

Safety

• If the detector is used in a potentially gas hazardous
environment, the relevant regulations for explosion classified
equipment must be observed at all times.
• Never change a sensor in a potentially hazardous atmosphere
while the transmitter is still powered.

Installation

Location:

Gas detectors should be installed where a potential gas hazard is
most likely to be present. Consider the behaviour of the specific gas
as well as factors such as the influence of temperature and natural
or forced air currents.
NOTE! Do not install the detectors on open weather
deck.
Location requirements for a correct function of the detector:
• Area free from shocks or vibrations
• Protection against rain or flooding
• Ease of access for maintenance and calibration purposes
Limitations for catalytic sensors (ST650EX):
• Minimum 10% oxygen in the surrounding atmosphere
• Not suitable for non-stop gas exposure
• Not suitable in areas where compounds containing silicon,
halogens, lead, organometals, sulphur, or organophosphates are
present

Mounting:

Arrange the detector in a vertical position, with the sensor pointing
downwards, to avoid accumulation of moisture, dirt, dust, silicone,
and/or chemical residue.

NOTE! The detector should always be mounted
vertically.
NOTE! To increase the oxygen sensor lifetime, avoid
exposing it to air until commissioning.
