Recycle characteristics:
Before time out: Power must be removed for 50 milliseconds or 5 percent of the nominal time
delay, whichever is greater, to insure a loss in timing no greater than 10 percent.
After time out: Power must be applied for 10 milliseconds or 1 percent of the nominal time
delay, whichever is greater, after which an interruption of 10 milliseconds will insure a loss in
timing no greater than 10 percent.
Polarity protection: The unit will be inoperative during, and undamaged by, reversal of the input
polarity.
