Updating Memory Card
To update the memory card values, follow the procedure described on first mode, setting
display 2 to
----
so as not to load the parameters on controller
1
.
Enter configuration and change at least one parameter .
Exit configuration. Changes are stored automatically.
7.9 Latch-on function
For use with input
Pot.1
(potentiometer 6 KΩ) and
Pot.2
(potentiometer 150 KΩ) and with
linear input (0…10 V, 0...40 mV, 0/4…20 mA), it is possible to associate start value of the
scale (parameter 6
LoL.i
) to the minimum position of the sensor and value of end scale
(parameter 7
uP.L.i
) to the maximum position of the sensor (parameter 8
Latc.
configured
as
Std.
).
It is also possible to fix the point in which the controller will display 0 (however keeping
the scale range between
LoL.i
and
uP.L.i
) using the “virtual zero” option by setting
u.OSt.
or
u.Oin.
in parameter 8
Latc
.
If you set
u.Oin.
the virtual zero will reset after each activation of the tool; if you set
u.OSt.
the virtual zero remains fixed once tuned.
Selecting “
dYn.L
” (dynamic limits) it is possible to surpass lower and upper limits if on
input there are values out of 0/4…20mA or 0…10V .
To enable the LATCH ON function select chosen configuration for parameter
LAtc

.
For the calibration procedure refer to the following table:

Place the sensor on minimum
operating value (associated
with

Place the sensor on maximum
operating value (associated
with

NB : For selection of
u.0in.
the procedure in point 4
should be followed on each
re-activation.
To exit procedure press

If on activation the controller does not display memo it means no data have been saved on the memory
card, but it is possible to update values.

The tuning procedure starts by exiting the configuration after changing the parameter.
