DI: Digital input; M: Electronics ground; M1, M2: Ground reference
Note
Ensuring the function of digital inputs
An open input is inte
rpreted as "low".
Terminal M1 or M2 must be connected in order that digital inputs (DI) can function.
This is achieved through one of the following measures:
1.
Provide the ground reference of the digital inputs
2.
A jumper to terminal M
Note
: This removes isolation for these digital inputs.
