127 (Escape). It is not possible to set extended ASCII characters (over 127) and
the control ones (from zero to 31).
Bits
:
Some parameters are managed in bit. Each bit at 1 enables a function and each
bit at 0 disables a function. Each bit is assigned a value. The parameter must be set
as the result of the sum of the values associated to the functions you require to enable.
8 bits can be used. The description of these parameters is shown in a table like the
one below:

Enable function 8
If the operator wants to:
o
Disable all functions: you must set 0 in the related parameter.
o
Enable all functions: the value to set is given by the sum
1+2+4+8+16+32+64+128 = 255.
o
Enable, for example, functions 3, 4, 6 e 8: the value to set is given by the sum
4+8+32+128 = 172 (where 4 is the value associated to function 3, 8 to function
4, 32 to function 6 e 128 to function 8).
Attention: the value must be set with the hexadecimal noting:
o

8.2.3
Set up limits
The operator has not to worry about verifying that the set up value is acceptable for the
controller since it is not possible to set up not acceptable values.
This goes for individual parameters; however, it is possible to set two or more parameters in
incongruent or incompatible ways. It is up to the operator to prevent this from occurring.
