Digital inputs |
To simplify adaptation to external functions, all digital inputs can be configured to be either Normally open (NO) or Normally closed (NC).
The inputs are as standard normally open, i. e. if the input is closed, the function connected to the input is activated.
Be careful when changing the input from NO to NC since some digital functions can be configured to either NO or NC themselves. For example, you can choose if the Fire alarm input should be activated when it is closed or opened. Therefore, there is a risk that the signal is changed twice and the result is the opposite of the desired.
