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.* For B856-
511, the instantaneous output will
activate upon the start signal 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 1
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.
Interval 2
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.*
The reset input is not used.
Reapplying the start signal has no
effect unless the cycle has
completed.
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.
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. T2 is settable from 0.1 to
999.9 seconds. The timing
sequence and output can also be
reset through the reset input or
interruption of power.*
