Fill Transition
Fill Transition is the user-defined Net Volume value to switch from full flow to
trickle flow.
Fill Transition Timer
After the transition from full flow to trickle flow, the Fill Transition Timer
value determines how long the trickle will last (that is, this feature sets the time
that the trickle valve is open or ON).
Alarms with the Filler Function
The module offers these alarms when operating the filler function:
•
Overflow Alarm - TotalCounts > RollOver Value
•
Overrange Alarm - FreqPeriod > 100kHz
•
Overspeed Alarm - Speed > Highest Allowed Frequency
•
Acceleration Alarm - Acceleration > Acceleration Alarm Value
You must enable each alarm. When any of the alarms occur, it is latched and
remains on until you reset the alarm. (Toggle the alarm enable bit to reset the
alarm.)
