Monostable Reset-Start/Stop
Activating the
CNT
input and keeping it active, the timer
resets and starts counting, disabling the
CNT
input the
count stops disabling the output if active.
This operating mode is similar to the one of the tradition-
al timers in which counting is enabled when the instru-
ment is powered while the
Reset
occurs when power
supply is removed.

Bistable Start/Stop-Reset
At 1
st
CNT
impulse the count is started, while at the 2
nd
impulse, if given before the end of the count, the count is
stopped disabling the output if active and reset, other-
wise, if the 2
nd
impulse should arrive after the end of the
count it starts directly a new cycle.

Out1 Operating mode
The Output 1 operation can be programmed in
6 different
modes
with
F.o1t
parameter:
F.o1t
=

-
ON DELAY
Received the
Start
signal, instrument starts counting and,
at the end of
S.t1
time, activates the
Out1
output. The
output is disabled by the
Reset
signal.

Feed-through
Received the

signal, the instrument starts counting
and activates the
Out1
output;
Out1 is disabled
when
S.t1
time has elapsed. The output can be reactivated
only after a
Reset
and a new
Start
signal.

Asymmetrical oscillator with start ON
This operating mode requires the setting of both
S.t1
and
S.t2
Set times.
Received the
Start
signal,
Out1
is enabled for the
S.t1
time
then disabled, reactivated when
S.t2
time has elapsed and
so on until the
Stop
/
Reset
signal is detected.

Asymmetrical oscillator with start OFF
This operating mode implies the setting of both

Set times.
Received the
Start
signal,
Out1
remains disabled for the
S.t1
time then is activated for the time set at
S.t2
and so
on until the

signal is detected.

Asymmetrical oscillator with start OFF 1 cycle
This operating mode operates as
f.o1t
=
4
but executes
only 1 Start/Pause
cycle.
Received the
Start
signal,
Out1
remains disabled for the
S.t1
time then is activated for the time set at
S.t2
.
The cycle can be repeated only after a
Reset
signal and
a new
Start
command.

Delay in lack of excitation (or delay in
de-excitation)
On the rising edge of the
CNT
input
Start signal
,
Out1
is
energized
. When the
CNT
signal
is removed
,
Out1 re-
mains energized
and
starts the
S.t1
count
elapsed which
Out1 is de-energized
. If, during the
S.t1
count, a signal
is detected on the
CNT
input, the
time is reset
and
will be
restarted
when
signal ceases
.
Note:
This functioning mode operates in this way
regard-
less
the
i.Fct
parameter setting.
Out2
output (if
used) in this operating mode
can only operate
in
F.o2t
=
1
or
2
modes. In
F.o2t
=
2
mode
OUT2
output is activated when the
CNT
input is enabled and
then deactivated when
CNT
input is disabled.
