2.5.4 Voltage level
Apply a DC voltage to the inputs (respect polarity). If the voltage is low (0 to 2.5 V), the function
is Active (or Inactive). If the voltage is high (4 to 24 V) the function is Inactive (or Active). The

2.5.5 Open circuit/Voltage level
Leave the circuit open or apply a DC voltage to the inputs (respect polarity). If the circuit is
open, the function is Active (or Inactive). If the voltage is high (4 to 24 V) the function is Inactive
Menu setting Input is 0 to 2.5V: Input is 4 to 24V:
