If you’re able to reset on of these (actually clear the counters C&D), it’s the same process for resetting each time. You’ll find with these particular models they’ll fault on a “time out” regardless of number of days since last reset. IIRC, time out was based on number of runs but that never seemed to be the case for me. Designed to force you to reset the counters (do your PM) before it hits that elusive magic number.
