• With the controller not connected to power supply:
The memory card is equipped with an internal battery with
an autonomy of about 1000 operations (button battery
2032, replaceable). Insert the memory card and press the
programming button .
When writing the parameters, the led turns red and on
completing the procedure it turns green. It is possible to
repeat the procedure without any particular attention.
nB
: it is not possible to transfer parameters to a device with
different code: red LED is ON.
updating Memory card
Insert memory card when controller is on, to copy
parameters. Enter configuration and change at least one
parameter. Exit configuration. Changes are saved automatically.
9.5 Latch On function
For use with input
po1
(potentiometer ≤ 6K) and
po2
(potentiometer ≤150K ) and with linear inputs (0..10Volt,
0/4..20mA), it is possible to associate start value of the scale
(par.
Lo. n.
) to the minimum position of the sensor and value
of the scale end (par.
Hi. n.
) to the maximum position of the
sensor.
It is also possible to fix the point in which the controller will
display 0 (however keeping the scale range between Lo. n. and
Hi. n. ) using the “virtual zero” option by setting u.0m or u.0s on
par. 8 Lat | Latc.
If
u.0s is selected
, lthe virtual zero will reset after each
activation of the device; with
u.0m
, the virtual zero remains fixed
once tuned. To use the LATCH ON function configure according
to required operation the par. 8

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