RECYCLE TIMING − The first delay period begins when input
voltage is applied. At the end of the first delay, or “ON” period, the
internal relay pulls in, and the second delay, or “OFF” period
begins.When the second delay period ends, the relay drops out. This
recycling sequence will continue until the removal of input voltage.
When input voltage is removed, the relay drops out.
