3.4 Programming
The parameters divide into 4 different levels according to their accessibility by the
user via password and their function. Entering a certain level it is possible:
1. to access all parameters of the same level and the lower levels (S-P menu);
2. set the desired level for each parameter (L-P menu).
3.4.1 Levels
“Factory”: accessible with password 66, it allows the configuration of all unit
parameters;
“Super User”: accessible with password 11, it allows the configuration of the Super
User, User and Direct parameters;
“User”: accessible with password 22, it allows the configuration of those parameters
that can be set typically by the user and Direct, therefore relative to the options.
“Direct”: accessible by pressing “ ” for 5 s, it allows to read the probes and any
data, which can be interrogated by anyone without compromising unit operation.
3.4.2 Default parameters setting
To enable the setting procedure for parameters at default values (controller power
supply with pressed) set the parameter H22 = 1.
Parameters modification procedure:
1. Press “ “ and “ ” for 5 s;
2. The and symbols appear along with “00”;
3. Set the password via “ ” and “ ” and confirm with “ “;
4. Select the parameters menu (S-P) via “ ” and “ “. Confirm with “ ”;
5. Select the parameters category (A,b,c,d..) via “ ” and “ “. Confirm with “ ”;
6. Select the parameter via “ ” and “ “. Confirm with “ ”;
7. Modify the parameter value with “ ” and “ ;
8. After modification, press “ ” to confirm or “ ” to annul the modification;
9. Press “ ” to return to the previous menu;
10. To save the modifications, press “ ” several time until going back to the main
menu.
Notes:
1.the parameters modified without confirmation via the “ ” key go back to the
previous value;
2. if no operations are performed on the keyboard for 60 seconds, the controller
exits the parameter modification menu by timeout and the changes are cancelled.
3. to modify the level of a parameter, enter the levels menu L-P and assign the
desired level to each parameter.
