#92729 - the problem Responding to: ???'s previous message |
the problem is NOT the reset at AC cutoff, it is the reset at AC return.
The AC cutoff is easy to catch, although it may cause you to enter PD, exit PD, enter PD. So, if you use a supervisor connected to voltage derived from AC only and make a port pin "see" that AC voltage exist, just enter PD every time you see no AC and you will be home free. Erik |
