p Analog sensors with ±10 V interface:
 In the form, the voltage at the input of the analog module is
displayed as a numerical value and in a bar graph.
Power supply
Check the supply voltage at encoder inputs X1 and X2 (optional). It
should normally be slightly above 5 V in order to ensure that the
voltage level at the encoder input complies with the specification (5 V
± 5%) even at greater cable lengths.
