Access to the configuration, and the display and
modification of the operative parameters, can be
protected by a secret code. The code is entered in
configuration, by means of parameters P11 and
P14.
P11 = 0 P11 = 0 P11 = 0 P11 = 0 P11 = 0 All the operative parameters can be
displayed and modified. Access to the
configuration is free.
P11 = 1 and P14 = On P11 = 1 and P14 = On P11 = 1 and P14 = On P11 = 1 and P14 = On P11 = 1 and P14 = On All the operative
parameters can be displayed but not modified,
apart from SP (Set Point). Access to the
configuration is only possible by entering code 408
when requested.
P11 = 1 and P14 = OFF No operative parameter P11 = 1 and P14 = OFF P11 = 1 and P14 = OFF P11 = 1 and P14 = OFF P11 = 1 and P14 = OFF
can be displayed and modified, apart from SP.
Access to the configuration is only possible by
entering code 408 when requested.
P11 = 2/499 P11 = 2/499 P11 = 2/499 P11 = 2/499 P11 = 2/499 In this case the value programmed in
P11 represents a numerical key which can be
used to protect access to the configuration and, in
operative mode, the modification of the
parameters (SP can always be modified).
To set P11 see section 4.4.
If the modification of the parameters has been
enabled, the passage in configuration is free.
If not it will be allowed by entering, when
requested, the numerical value programmed in
P11, or code 408.
P11 = 500/999 P11 = 500/999 P11 = 500/999 P11 = 500/999 As for the previous point, with the P11 = 500/999
difference that AL (alarm threshold) can be
modified as well as SP.
In the two previous cases, with P14 = On the
parameters set as not modifiable can however be
displayed. With P14 = OFF they are not.

To access the configuration, press SMT and
FUNC simultaneously (press first SMT and
immediately afterwards FUNC) keeping both the
pushbuttons pressed for three seconds.
