92 EL3060 CONTINUOUS GAS ANALYZERS | OI/EL3060-EN REV. A
Externally controlled sample component switch-over
Description
Externally controlled switch-over of the active sample component is possible
via appropriately configured digital inputs (see page 39). The respectively
configured digital outputs are required for sample component feedback.
Function
The sample component is activated via a signal on the digital input which is
assigned to the sample component switch-over. The respectively configured
digital output is set for feedback of the active sample component.
After a restart of the gas analyzer, the sample component which was last
saved as active is active again unless there is a signal present on one of the
configured digital inputs.
Configuration with ECT
In the example shown in the figure, the following digital inputs and outputs
are assigned to the sample components of the Caldos27 detector (see yel-
low marking):
• The digital inputs X24-DI2 to X24-DI4 are for the external control of the
sample component switch-over ("Comp. Control") and
• The digital outputs X24-DO2 to X24-DO4 are for the sample component
feedback signal ("Comp. Feedback").
