General Specifications
KZR / SZR are the delay on timer.When the application of voltage to the
timer’s supply inputs, the counter starts counting (1-2 contacts are
shortcut).End of the adjusted time, counter stops counting and the output
becomes on (2-3 contacts are short cut). When the supply voltage cut off,
the timer reset.
