ABB EasyLine EL3000 Continuous Gas Analyzers

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 Configuration 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 switchover: – 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.
