Operation of the switch time delay
DELY
:
Using this setting a time delay
DELY
between switch threshold
SETP
and activating the alarm indicator/relay can be installed.
If the measurement value falls below the preset switch
threshold
SETP
(without hysteresis) within the time delay
DELY
then the switch delay time counter is reset to zero. The time
counter restarts after a new infringement of the preset switch
threshold
SETP
.
This is also valid for minimum monitoring.
