average alarms will be activated. In the LEL profile average alarms are forbidden
and therefore the option is not visible in the related alarm window.
2)
The
“Gas Type”
represents the list of gases belonging to the related
“Profile”.
for each gas type the formula and the % LEL-value or for toxic gases the
TLV of the gas are indicated.
3)
The
“Detector Model”
lists the available detectors measuring the chosen gas
of the related profile. A detector is related to
one specific gas to be measured.
a value for full scale e.g. 100% LEL ; 300 ppm CO ; 1000 ppm CO
The “Detector Model” lists the available detectors for the chosen gas. For each
detector model default values are automatically set e.g. for alarm levels.
Alternative approach with known detector type:
1)
Choose the detector model e.g. the type “S1096PR” from the long drop down
list of all detectors available.
2)
Automatically the Profile “LEL” and the Gas-Type “Propane” will be indicated.
The
“Channel Description”
is not mandatory for the reliable function of the gas
detection system. It is an aid for the user to indicate useful additional information in
the case of alarms.
In the case of alarms all information related to the detector(s) in alarm condition will
be indicated at the display on request.
The
“Channel Description”
may be additional to the “zone” description and may
include data according redundancy to another channel or describe the measurement
task in detail.
