Hi all
I found this picture on one forum. The original poster said the system is used to control a solenoid valve for sprinklers in repeat cycle manner, i.e. on for a set time and off for another set time and repeat on and so on.
Unfortunately the poster said it does not work correctly. My question is can we connect two timers as shown in the picture to make a repeat cycle(twin timer).
If not, how to make it works.
My guess is that the left timer is a countdown timer with solenoid valve(and so the transformer) connected to NO. When the system starts, the vale is on for a set period of time then the timer switch to NC. NC pin feeds the right timer and start a countdown "off" time. When the right timer off time is reached it switch off the line that feed the left timer.
But then I don't know how the left timer would start again , so can this possibly works?
Any idea?
Mick
