Figure 3: Well and Pump Control via Machine-to-Machine Commands
Let's suppose the well level is 25' and you need to maintain the
level between 5' and 20'. The first thing you would need is a level
transducer in the well. Next, program your two machine-to-machine
events into the WTU-14 located at the well. The first would be to
turn ON the pump if the level is Less-Than 5'. The second event
would be to turn the pump OFF if the level is Greater-Than 20'.
Consider the rate at which the well fills when the pump is running,
in order to account for the machine-to-machine command delay
time between the WTU-14 units. Also note that machine-to-machine
control is completely independent of alarm processing, so you can
also trip high or low-level alarms based on the well level.
