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