Timing begins on the leading edge of the start input. The output will activate
at the completion of the preset time (T) and will remain active until the reset
signal is applied or power is interrupted.*
The output is activated at the leading edge of the start signal. Timing begins
on the trailing edge. The output will remain active until the preset time (T) has
elapsed or power is interrupted.* Reapplying the start signal before T has
elapsed will reset the time value. The reset input is not used.

Repeat Cycle
Timing begins on the leading edge of the start signal. A cycle is initiated
where the output will be OFF for the preset time (T), then ON for the preset
time. This cycle will continue until a reset signal is applied or power is
interrupted,* The unit can also be programmed for the timing sequence to
begin with an ON cycle.

On the leading of the start input, the output is activated and timing begins.
The output will remain active until the preset time (T) has elapsed or power is

deactivated and the time value to be reset. The reset input is not used.

Delay/Interval
The delay cycle begins upon application of the start signal. The output will
activate at the completion of the preset time (T1). Upon activation of the
output, the Interval cycle will begin. The output will be deactivated at the end
of the Interval time (T2). T1 is the primary preset value and is set in Operation
Mode. T2 is set in Program Mode in a range from 0.1 to 999.9 seconds. The
timing sequence and output can also be reset through the reset input or
interruption of power.*
* The Power Reset parameter in Program Mode can be set so that a timing
sequence will not be reset upon power interruption but instead continue
on when power is restored.
