Revision D.0
3.2 Gas detectors
Refer to the manual supplied with each detector.
3.2.1 Location
Each detector shall be positioned at ground level, on the ceiling, at human height or near air
extraction ducts, depending on the density of the gas to be detected or the application. Heavy
gases are detected close to the ground, while lighter gases are present along the ceiling. If
necessary, contact
TELEDYNE OLDHAM SIMTRONICS
for any questions regarding proper
detector positioning.
3.2.2 Fixing
The detectors shall preferably be positioned in an accessible place so that inspections and
maintenance can be carried out as well as to ensure the absolute safety of the operators. The
detectors must not be obstructed by anything that will prevent them from measuring the ambient
environment to be checked.
3.3 Digital Modules
For cabling and electrical information see paragraph
Connections
on page 33.
LocationThe relay modules, logic outputs, analog outputs, and analog inputs are positioned
depending on the installation layout, mandatorily in places free from explosive atmospheres,
protected from humidity, dust, and temperature variations; for example in technical cabinets.
Fixing
These modules shall be mounted on a DIN rail in
a cabinet or in an electrical cabinet.
For relay
modules connected to low voltage electrical
parts, the installation is carried out according to
the standards in force.
