Figure 3.10 - Jumpers position for selecting the analog inputs and outputs operation mode (voltage - 0 to 10 Vdc
or current - 0 to 20 mA / 4 to 20 mA) as well as the digital inputs operation mode (high logic level - PNP or low
logic level - NPN). Refer to the digital inputs definition on items 3.2.5.1 and 3.2.5.2

As a default, the analog inputs and outputs are set to voltage
mode (0 to 10) Vdc and the digital inputs are set to active
(NPN logic). Change it by using DIP switch S1 (refer to figure
3.10) on the control board and by setting parameters P235,
P239 and P253 (refer to table 3.6).
Factory Default Setting
Table 3.6 - Dip switch configuration (inputs and outputs)
NOTE!
If it's used a (4 to 20) mA signal, set parameter P235, P239
and P253 that defines the signal type at AI1, AI2 and AO
respectively.
The parameters related to the analog inputs are: P221,
P222, P234, P235, P236, P238, P239, P240, P251, P252,
P253.
