Power-ON Start/Power-OFF Reset

The start terminals are connected. Timing starts when power is

applied. 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.

Mode C

Signal ON/OFF-Delay

Power is continuously applied. Timing begins on both the leading

and trailing edges of the start input. The output relay is energized

during timing. Once the timer has timed out from the trailing edge,

it resets and is ready for subsequent start inputs.

Mode D

Signal OFF-Delay (I)

Power is continuously applied. The output relay is energized at

the leading edge of the start input. Timing starts at the trailing

edge of the start input. The output relay is de-energized when the

accumulated time equals the set time.
