Start End
The KI recorder follows the course of the process and releases a messages in
the event of a deviation. It is called from the measuring mode: meas
Continuous processes
The measured signal is surrounded by a dynamically tracked,
process- controlled tolerance band. Slight fluctuations are tolerated.
If the measured value leaves the tolerance range, a message is released (Fig.).
The recording interval can be set from 10 s to 60 h.
Batch processes
The KI recorder provides an automatic self-learning function. This allows
checking whether regularly recurring processes keep the preset tolerances.
Deviations from the normal course of process (plus preset tolerances) generate
a message (Fig.). Maximum process duration can be set from 1 to 60 h.
