The programming module is equipped with an internal battery with an au-
tonomy of about 1000 uses (2032 button battery, replaceable).
Insert the programming module and press the programming buttons.
When writing the parameters, led turns red and on completing the proce-
dure it changes to green. It is possible to repeat the procedure without any
particular attention.
WARNING
Updating Programming module
To update the programming module values, follow the proce-
dure described on rst mode, setting display 2 to
---- so as
not to load the parameters on controller
1
.
Enter conguration and change at least one parameter.
Exit conguration. Changes are stored automatically.

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

7.10 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 asso-
ciate 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. congured as Std. ).
It is also possible to x 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” op-
tion 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 xed once tuned.
To enable the LATCH ON function select chosen conguration for parameter
LAtc

.
For the calibration procedure refer to the following table:

The tuning procedure starts by exiting the conguration after changing the parameter.
