Hello to all,
I’ve go an interesting problem. It’s is about an timer.
We’ve have programmed a “on delay” timer witch waits for an input and after the input (logical 1), the input shows a negative flank (logic 0) the timer starts to run for a period of 1 minute. If the input is a 1 the output of the timer becomes a 1 to until the time has elapsed.
The problem is that after the minute the output signal of the timer still is a 1 and the time starts to count again.
You’ve got something like a endless loop.
The input of the timer is (the SET condition) a valve is open and we’ve got no RESET because the output will be a logical 0 if the time has elapsed. Well normally spoken.
Does anyone have any idea how this is possible and if there is some solution for this (except “use an other timer”)?
