Assembly and installation instructions
Parameter P44
Parameter P44 is used to set the function of the digital input DI2 when DIP
switch no. 4 = OFF.
Parameter P56
The polarity of digital input DI2 is set using parameter P56 when setting
DIP switch no. 4 to ON.
The digital input DI1 is predominantly used to execute specific functions. If
the use of the digital input DI2 is needed, then the following settings have
to be made:
1. Set DIP switch no. 4 to OFF.
2. Configuration of the digital input DI2 using parameter settings P44.
