Hello, I hope I'm allowed here - I know very little about electronics.
I have an LCD panel mount counter that works on 10-300 VDC and 20-300 VAC and I want to count the number of times my well pump (240 VAC) activates.
I connected the counter to one side of the well pump power (120 VAC) but in addition to the counter incrementing once when the pump turns on, it also increments 2 or 3 times when the pump turns off. The counter's specs say it will register 40 pulses per second. (If each pump cycle were counted consistently I could just divide the count to get my actual number of cycles - but sometimes it increments 3 and sometimes it's 4)
I added a solid state relay (control 120 VAC) thinking that would correct the problem, but when it did not correct the problem, I realized that the relay was just responding to the pulses just as the counter was.
I searched the Web for a constant to momentary circuit or relay and all I found were solutions for 12 VDC.
Does anyone know of a source for a solution that is a circuit I could build that would make the relay fire momentarily?
Or any fairly simple and inexpensive alternate way to achieve the same results?
I would prefer that the solution fit inside a single-gang wall box for simplicity, but if I have to add components outside the box that will be okay.
Thank you for your help.
