If an input pulse is received before the end of the set time period, the relay continues operating for a full new time period starting at the leading edge of the input pulse. If the set time period expires before a new input pulse is received, the relay releases. Wiring Diagram Example 2 Start with relay OFF The relay operates and the time period starts at the leading edge of the first input pulse. If a new input pulse is received before the end of the set time period, the relay continues operating for a full new time period starting at the leading edge of the new input pulse. If the time expires before a new input pulse is received, the relay releases. Time Setting L µ Selection of time ranges Upper knob: 3-position rotary switch.
