Note
The process controller automatically checks to ensure that
the entered data matches other related variables. If a wrong
configuration is entered, “WRONG” blinks on the LCD to
prompt the user. The correct configurations are the following:
If M1=
/ 0 then S1
If M2=
/ 0 then S2
If M1= 1 then S1-H1>LA;
If M1= 2 then S1+H1
If M2= 1 then S2-H2>LA;
If M2= 2 then S2+H2
If M1= 1 and M2 = 2
then S1-H1>S2+H2, S2>LA, HA>S1;
If M1 = 2 and M2 = 1
then S2-H2>S1+H1, S1>LA, HA>S2;
If M1 = 3 and M2 = 2
then S1>S2+H2, S2>LA, HA>S1+D1;
If M1 = 2 and M2 = 3
then S1+H1
If M1 = 4 and M2 = 1
then S1
If M1 = 1 and M2 = 4
