4.10.2 Application Examples
Rain Gauge :
Each time a tipping bucket fills and tips, a contact opens indicating that 0.1 inch of rain has filled the bucket.
Attaching the L404 to this contact allows recording of both the number of times the bucket has tipped, as well
as the totalization of rainfall during the recording.
In the configuration menu, the user has the ability to program both the weight and value of an event pulse. In
this case, the weight would be 0.1 and the value would be in inches.
In the Figure 4-2, eight tips occurred for a total of 0.8 inches of rainfall.
Sequencing:
In a processing plant it has been determined that timing on several positions is out of specification. The
service staff needs to know the sequence of valve opening and closing, and the duration of each, to correct
the problem. The L404 can be connected to four valves in the process and keep track of the time and
duration of each opening and closing, thus providing the technician with the data they need to solve the
sequence issue.
In the example below we can see that the valve 1 opened and closed several times during a one minute
period, but valves 2, 3 and 4 did not respond.
