Free Form Logic
Lets you enter up to 64 characters as a custom logic equation (EQ) containing inputs and logical operators.
The result of this equation is called "Result". Result is then processed according to the specified condition
type and condition time. The final output is CVn OS. See Figure 4-7 .
Table 4-27 describes the Free Form Logic prompts. See Table 4-2 for additional prompts.

Letter O is the symbol for output CVn OS from the previous
logic calculation. Use for iterative calculations.
One = ON
Zero = OFF
Expressions enclosed by parentheses are evaluated first.
Up to 8 input sources.
Resets the output to OFF (0). Use when using the letter O
in equations.
