Hello Jon,
I sent Mark Phillips (at the possum works) a couple of general purpose time
delay relay modules that I use from time to time in my electronics control
business. They are dip switch settable to do many functions, are dual
voltage (12 & 24) and they cost less than twenty bucks each. I bread boarded
for Mark a configuration that will do just what you are asking. He is using
two tanks with a module controlling the low fuel light for each low fuel
sensor switch. A count down time delay can be set so that the LED is kept
off until the time out is complete. The low fuel sensor must remain in alarm
during the entire count down to turn the LED on. A return to normal signal
from the low fuel sensor cancels the time out. Both sensor alarm input and
completed time delay must be true to turn the light on.
He may see this post and chime in to let you know how they are working out
for him so far.
