In the schematic diagrams, each thick line indicates the external wiring necessary for the selected operation.

The start terminals are connected. Timing starts when power is

applied. The output is energized when the accumulated time

equals the set time. The output remains energized until power is

disconnected or a reset input is applied.

Timing Charts

Power is applied continuously. Timing starts at the leading edge

of the start input. The output is energized when the accumu-

lated time equals the set time. Subsequent start signals during

or after timing will not be accepted. The output relay will remain

energized until a reset input is applied or power is interrupted.

Signal Start

Power is continuously applied. The OFF/ON cycle is initiated at

the leading edge of the start input. The output relay will be OFF

for the set time and then ON for the set time. This cycle will be

repeated until a reset input is applied or power is disconnected.
