Operating Modes
| On-Delay
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.
|
 |
| Off-Delay
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.
|
 |
| Interval
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
interrupted. Removal of the start signal will also cause the ouput to
be deactivated and the time value reset. The reset input is not used.
|
 |
| Repeat Cycle
Timing begins on
the leading edge of the start input. 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-Delay/Interval
Timing begins on
the leading edge of the start signal. The output turns ON when the
delay preset time (T1) has elapsed. The output remains ON for the
duration of the interval time (T2), then turns OFF. T2 is settable
from 0.1 to 999.9 seconds
