Ok here is the issuse chiller system that doses 3 chemicals
1 every 36hrs of run time
so chem 1 at 36 hours
chem 2 at 72 hours
chem 3 at 98 hours
then starts over after 36 hrs
this is done with a micrologics 1500 just by timer done bits turning on second and thrid timers
but the issue is if we lose power
we you get power back the program starts at the 1st chem
Is there a way to make it know what chem got dosed last if that makes sense
The only thing I can think of is a back up power supply
