Digital Input Functions
On ATR142 model, digital input can be enabled by using para-
meters 48
op.mo.
and 50
dGt.i.
• Parameter 48
op.mo.
cont.
: Operating as controller.
NB : When using this settings, parameter 50
dGt.i.
is ignored.
2t.s.
: Switch two thresholds setpoint: with open contact
ATR142 regulates on SET1; with closed contact regulates on
SET2;
2t.s.i.
: Switch two thresholds setpoint: setpoint selection is
done by an impulse on digital input;
3t.s.i.
: Switch three thresholds setpoint by an impulse on
digital input;
4t.s.i
: Switch four thresholds setpoint by an impulse on
digital input;
p.r.c.Y.
: Pre-programmed cycle (par. 7.7).
Setpoints values can be modified any time pressing key.
• Parameter 50
dGt.i.
NB : Settings on this parameter are available only if
cont.
or
pr.cY.
are selected on parameter 48
op.mo.
st.st.
: Start / Stop; operating on digital input the controller
switches alternatively from start to stop;
rn.n.o.
: Run N.O. Controller is in start only with closed input;
rn.n.c.
: Run N.C. Controller is in start only with open input;
L.c.n.o.
: With closed input allows to lock the reading of sen-
sors;
Lc.n.c.
: With open input allows to lock the reading of sensors;
tune
: Enables/disables Tuning function if parameter 46
