MIL-R-83726/8E
Recycle characteristics:
Before time out: Control power must remain off at least 25 milliseconds or 1 percent of the nominal time delay, whichever is greater, after which reapplication of control power for 25 milliseconds minimum will recycle the timer with a loss in timing no greater than 10 percent.
After time out: Reapplication and subsequent removal of control power will recycle the timer. Control power must be applied for 25 milliseconds or 1 percent of the total time delay, whichever is greater, to insure a loss in timing accuracy no greater than 10 percent.
Polarity protection: The unit will be inoperative during, and undamaged by, reversal of the input polarity.
