Integral gas feed
Versions
The integral gas feed (optional in model EL3020) is available in
two versions. It includes
– either the solenoid valve, pump, coarse filter, capillary tube
and flow sensor modules
– or the flow sensor module.
The integral gas feed cannot be installed when the internal gas
lines are made up of PTFE or stainless steel pipes. It cannot be
used in combination with Limas23 or ZO23.

Gas inlet conditions
The integral gas feed modules must not be used for measure-
ment of flammable gases and ignitable gas/air or gas/oxygen
mixtures.
Temperature
+5 to +45 °C
The sample gas dew point should be at least 5 °C below the
temperature throughout the sample gas path. Otherwise a
sample gas cooler or condensate trap is required.
Flow rate
30–60 l/h
Corrosive gases
Corrosive associated gas components and aerosols must be
cooled or undergo prior absorption.

Housing purge
Possible only with model EL3040 (wall-mount housing).
Housing purge is mandatory when measuring flammable
gases (see page 16). Purge gas flow during operation

Display and operation
Display
Backlit graphics display with 240 x 160-pixel resolution
Measured value display
– Numerical value with physical unit,
also with bar graph indication in single display
– Resolution better than 0.2 % of the measurement span
– Simultaneous display of up to 5 measured values
– Flow: bar graph indication
Status display
Symbols in the display; the active status messages can be
accessed directly from the measured value display
Operation
5 keys (cursor cross and OK); menu-assisted operation
Concept of operation
The functions required in normal operation are operated and
configured directly on the gas analyzer. The functions which
are only seldom required, e.g. during start-up, are configured
offline using the configuration software ECT ("EasyLine Con-
figuration Tool" on the enclosed CD-ROM) and then loaded
into the gas analyzer.
Measuring range switch-over and feedback
There are three ways of executing the measuring range
switch-over:
– Manually on the gas analyzer
– Automatically (autorange) by means of appropriate
configured switch-over thresholds
– Externally controlled via appropriately configured digital
inputs.
The measuring range feedback can be implemented via
appropriately configured digital outputs; it is independent of
the selected type of measuring range switch-over.
The gas analyzer is set ex works to measuring range 2 and to
manual measuring range switch-over.
Limit value monitoring
Limit values can be set using the configuration software ECT.
The limit value signals (alarms) are output via digital outputs.
