Bistable Reset-Start/Stop
At the 1
st
impulse on the
CNT
input the timer is reset and
started, at the 2
nd
impulse, if given before the end of the
count, the count is stopped (disabling the output if active)
and the 3
rd
impulse starts a new cycle, otherwise, if the
2
nd
impulse should arrive after the end of the count it
starts directly a new cycle.
In this mode, the front
-Start/Stop
button (if
t.UFt
=
2
)
acts in exactly the same way as the
CNT
input.

Monostable Start/Stop
Activating the
CNT
input and keeping it active, the count
is started; the count stops on the value reached when
the input is disabled (without disabling the output if ac-
tive); re-activating the
CNT
input, the count restarts from
the value reached and so on until the
Reset
signal.
In this operating mode, the front
-Start/Stop
key (if
t.UFt
is different from

) only acts as a

Monostable Reset-Start/Stop
Activating the
CNT
input and keeping it active, the timer
resets and starts counting, disabling the

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.
In this operating mode, the front
