Hello,

I have a pump that runs occasionally, and I want to monitor it. I want to set an output when it runs for two hours. When I use the on time function, the pump stops counting when it stops. How can I fix this? The algorithm will be as follows: The timer will count as the I5 input arrives, and when it reaches two hours, Q1 will output. However, this I5 only completes two hours in a month.

Hello,

The picture below has two instructions highlighted.
Each represent one possible option.
HOURS COUNTER is the one meant for this task.
Have a read in the instruction help what each offer.
Activate the retentive attribute to keep memory through a power outage.

Hello,

Due to the short operating time of the pump, the LOGO's operating hour counter is too inaccurate! Here is a good solution for recording these short operating times.

Hello AutoGen,

Quirin has presented a really nice overall concept .

I, on the other hand, use a counter for time recording. It's timed via the stopwatch. This is a bit more accurate than the Logo's pulse generator. After two hours (7200 seconds) of activation via I5, Q1 is switched on.
