This v alue is usually set to be slightly g reater than the f astest process response
expected during a 1 second per iod, b ut measured for at least 2 seconds. If the
process is f aster than this setting, the SEnC bAd error message will appear. The
outputs will then be tur ned off . This function can be used to detect a r unaw ay
