Closing the control input A1-Y1, with control supply voltage
applied, energizes the output relay for the selected ON time.
Operating the control input during timing has no effect. When
the ON time is complete, the output relay de-energizes.
Timing can be restarted by re-closing control input A1-Y1. If
control supply voltage is interrupted during timing, the output
relay de-energizes and the ON time is reset.
