An open input is interpreted as "low".
Note
Terminal M1 must be connected for the digital inputs (DI) 0 to 3 and 16/17 to function. This
can be done as follows:
● Connect the ground reference of the digital inputs.
● Jumper to terminal M: This removes the electrical isolation for these digital inputs.
