Hi,
I am trying to make a battery powered garden timer with a stack of solenoid valves I have come across. The solenoid on the valve model is a bermad S392 and the data sheet indicates that 9v connection one way will latch the valve open and 9v the other way will latch it closed.
My experimenting yields different results. The valve is normally closed and supplying 9v opens the valve while energised but when the 9V is disconnected, it fails to latch. I have tried adding a 4700uF capacitor and also tried a 12V lipo battery (capable of 30A) and I get the same result.
Any assistance would be appreciated.
Thanks,
Kim
